 ### Testing
 
 Use compile-time fixtures to verify the published type contract. Reserve runtime tests for behavior that can fail at runtime; avoid testing guarantees already enforced by the type system.

+# Dependency installation
+
+Use the pnpm version pinned in `package.json`. Keep these workspace settings:
+
+```yaml
+minimumReleaseAge: 10080
+minimumReleaseAgeStrict: true
+minimumReleaseAgeIgnoreMissingTime: false
+trustLockfile: false
+```
+
+Every registry version, including transitive dependencies, must have a known publication time
+at least seven days old. Do not approve pnpm's interactive exception prompt, add an exclusion,
+override these settings through flags or environment variables, trust the lockfile without
+verification, use an alternate installer, or replace an ineligible registry package with a direct
+URL or copied artifact. This also applies to package-manager and tool upgrades: verify their
+publication dates before updating their exact pins.
+
+Run workspace installs from the root. CI and the Dev Container retain `--frozen-lockfile` and the
+existing `allowBuilds` lifecycle permissions. Frozen lockfiles and cached artifacts are rechecked
+against registry publication metadata; neither supplies an age exemption.
+
+For a temporary consumer, call `writeConsumerWorkspace` from `scripts/install-policy.mts` before
+its pnpm install. It copies the full workspace policy, including catalogs and lifecycle permissions,
+and rejects weakened quarantine settings. Preserve `--ignore-scripts` for packed consumers.
+Locally built project tarballs are repository artifacts; their registry dependencies still need
+to satisfy the quarantine.
+
+When an install fails, record the rejected version, registry publication time, and earliest
+eligibility time. A missing publication time remains a blocking condition. Continue independent
+work using already-installed dependencies read-only. Do not weaken the policy to unblock work.
+
+Run `vp run install-policy` after changes to installation policy or consumer setup. This invokes
+the real pnpm CLI against an isolated fixture registry and checks fresh resolution plus frozen
+installs with cached artifacts, including under-age and missing-time rejection. The normal packed
+consumer checks verify real eligible registry dependencies with the same copied policy.
+
+After publishing a new package version, registry installation waits for that version's own
+seven-day eligibility. Metadata and provenance checks and local-tarball acceptance may run sooner.

+# Use public decoded-message clients for server-local RPC
+
+Status: Accepted. Extends [ADR 0007](0007-keep-the-core-factory-lifecycle-neutral.md)
+and [ADR 0019](0019-host-effect-rpc-inside-tanstack-start.md).
+
+Effect 4.0.0 exposes `RpcServer.makeNoSerialization` and
+`RpcClient.makeNoSerialization` as public constructors for decoded message
+channels. An application may connect their write callbacks within its own
+Scope, supply the server handler and middleware Context, and pass the resulting
+flat ready client to `createRpcQueryUtils`. Server-local execution therefore
+needs no loopback request or library-owned client factory. The browser keeps
+its independently scoped HTTP or socket client.
+
+Use a separate connection and QueryClient for each request identity. The
+server-owned handler Context determines services and authority; validate
+request headers in middleware. Do not substitute arbitrary caller Context for
+the server Context. Keep stream acknowledgements enabled, and set the server's
+`disableFatalDefects: true` to preserve complete failed Exits rather than
+collapsing fatal defect Causes. Cancel queries before closing the caller-owned
+Scope.
+
+This route constructs payloads and carries decoded values, middleware headers,
+Exits, acknowledgements, and interrupts. It deliberately performs no transport
+Schema encoding or decoding. Native call types retain residual Schema service
+requirements, so the adapter still requires the application's matching runner;
+this does not prove that codec effects execute on a decoded channel. Applications
+that require wire validation or codec side effects should keep the schema-aware
+`RpcClient.make` protocol. An application-owned `FetchHttpClient.Fetch` can
+dispatch that protocol to its existing Web handler without a network request;
+that separate recipe must verify its own transport and resource semantics.
+
+The bounded executable proof is
+[`tests/create-rpc-query-utils-server-local.test.ts`](../../tests/create-rpc-query-utils-server-local.test.ts),
+with its application recipe in
+[`tests/fixtures/server-local-rpc.ts`](../../tests/fixtures/server-local-rpc.ts)
+and native service/type evidence in
+[`tests/types/server-local-client-contract.ts`](../../tests/types/server-local-client-contract.ts).
+It uses the public constructors directly, with the network fetch boundary
+disabled. It verifies decoded class behavior, payload defaults, authenticated
+request isolation, complete Causes, cancellation, finalization, and independent
+Scope disposal. `RpcTest` and `HttpApiTest` remain test support rather than
+production construction guarantees. The unstable upstream constructors remain
+qualified by the package's exact Effect peer.
+
+`vp run test` includes the native constructor contract through
+`vp run server-local-types`, using the repository compiler and TypeScript 5.9.

+# Project HTTP streams and buffered metadata into separate cached views
+
+Status: Accepted design for the review programme. Implementation follows in issues #104–#106.
+Amends [ADR 0020](0020-generate-accumulated-and-live-stream-queries.md),
+[ADR 0022](0022-add-buffered-http-utilities-with-separate-key-roots.md), and
+[ADR 0023](0023-expose-buffered-multipart-http-mutations.md).
+
+## Decision
+
+An endpoint with exactly one success alternative, whose body is `HttpApiSchema.StreamSse`,
+exposes accumulated and live query builders. A declared `WithHeaders` wrapper projects onto each
+emitted chunk: `HttpApiSchema.withHeaders({ body: chunk, headers: decodedHeaders })`. Accumulated
+query data is an array of those values; live query data is the latest value. Neither view caches a
+Stream or a response object. An unwrapped successful live `undefined` becomes `null`; an accumulated
+`undefined` element or a declared wrapper containing it keeps its original representation.
+
+Keep the existing `streamedKey`/`streamedOptions` and `liveKey`/`liveOptions` vocabulary. Accept
+`sseOptions` beside `input` in option builders and beside the retention policy in concrete key
+builders. Decoded request input and custom key-encoder input contain only declared request parts.
+Normalize the installed decoder's `maxEventSize` default to 10 MiB of string code units. Its
+effective value belongs in both concrete view keys because it changes successful consumption into
+a failure for sufficiently large pending events. Accumulated identity also includes effective
+`maxChunks` and `refetchMode`. Key-prefix invalidation remains independent of those concrete policies.
+
+Expose `metadataKey`/`metadataOptions` on query-enabled buffered endpoints. Execute the ready
+client with `responseMode: 'decoded-and-response'` and return a readonly, frozen outer record
+`{ data, status, headers }`, with copied, frozen plain string headers. Normalize decoded `undefined`
+to `null` in `data`; preserve any declared decoded `WithHeaders` value intact. Give this view its
+own `metadata` operation identity. Ordinary query, infinite-query, and mutation behavior stays as
+specified by the existing buffered contracts. Header copying reads raw string entries rather than
+Effect's redacting `Headers.toJSON` representation.
+
+The supplied ready client and runner own encoding, middleware, residual services, and transport.
+Acquire the SSE value and consume it under the caller's runner Context; forward Query's abort
+signal and close the iterator on cancellation. Both acquisition and consumption failures retain
+the complete Cause in `EffectHttpApiQueryError`, with `streamed`, `live`, or `metadata` operation
+metadata. An independent interruption is a failure; signal cancellation follows native Query
+reversion. Empty accumulated completion succeeds with the appropriate retained history. Empty
+live completion raises `EffectHttpApiQueryEmptyStreamError` with declaration identity. Runner
+rejections pass through unchanged.
+
+## Supported limits
+
+Effect 4.0.0 permits only one streaming success alternative, but it can combine that alternative
+with buffered successes selected by status/content type. Such a ready client can return either
+buffered data or a Stream. Keep the whole mixed endpoint omitted: assigning a stream view or a
+buffered view would misrepresent one successful outcome. Revisit only with an explicitly proved
+discriminated contract. Streaming multipart request payloads remain omitted. Buffered multipart
+requests remain mutation-only when their successes are buffered; they do not gain SSE query views.
+
+Keep raw `StreamUint8Array` successes omitted, including wrappers and mixed alternatives. Transport
+chunks partition the same bytes differently, and `maxChunks` counts transport chunks rather than
+bytes or application records. A latest-chunk cache is not a download snapshot. Applications can
+consume the native ready client into their own sink or declare an explicitly buffered byte result;
+this programme adds no generic download accumulator or sink ownership.
+
+SSE event declarations preserve their declared event fields and IDs; data declarations emit only
+decoded data. The adapter does not reconstruct dropped event IDs, reconnect, retry a parser
+directive, or invent resume semantics. `Sse.Retry`, its `lastEventId`, and all other failures remain
+available in the Cause for an application-owned retry/resume policy.
+
+The [support matrix and proof](../design/http-cached-views.md) record the exact upstream seam,
+service channels, resource behavior, and executable evidence behind this decision.

+# HTTP cached-view contract and design proof
+
+This is the implementation contract for issues #104–#106 under spec #95. The retained proof uses
+the already installed Effect 4.0.0 public exports. It does not install dependencies or add shipped
+features. [ADR 0024](../adr/0024-project-http-streams-and-buffered-metadata.md) records the decision.
+
+## Input and output support matrix
+
+The request and success rows compose: a request must permit a particular view and its success
+must have the corresponding representation. HTTP method does not determine cache capability.

+Native transport headers declared as request input, including an application resume cursor, remain
+request identity input. Middleware-owned identity must be partitioned in the caller's key prefix.

+
+For ordinary query data and live values, successful top-level `undefined` becomes `null`.
+Accumulated arrays preserve `undefined` elements. Metadata normalizes its decoded `data` field;
+it leaves a decoded wrapper and its fields unchanged. Live completion preserves the latest value;
+completion without any emission is a distinct package empty-stream error.
+
+## Concrete interface
+
+Streaming leaves provide `key()`, `streamedKey(...)`, `streamedOptions(...)`, `liveKey(...)`, and
+`liveOptions(...)`. Query-enabled buffered leaves additionally provide `metadataKey(...)` and
+`metadataOptions(...)`. The metadata result shape is
+`{ readonly data: QueryData<DecodedSuccess>; readonly status: number; readonly headers: Readonly<Record<string, string>> }`.
+Metadata gets the normal unary options' native selection, initial-data, skip-token, and error
+inference with this result shape. It does not create metadata mutation or infinite-query methods.
+
+Option builders accept `sseOptions?: Sse.DecodeOptions` alongside `input`, with accumulated
+`maxChunks` and `refetchMode` alongside it. Concrete key builders accept the same policy object
+after decoded input, or as their only argument for inputless endpoints. Live concrete key policy
+contains only decoder controls. Prefix keys continue to select every policy for that endpoint.
+
+The installed decoder has one control, `maxEventSize`. Absent options, an empty options record,
+an undefined field, and the explicit 10 MiB default must have identical normalized identity. A
+non-default effective limit splits both SSE views. Require a positive safe integer and reject
+invalid values synchronously with a configuration error. This protects finite, JSON-safe view
+identity. The same normalized value must be passed to the ready client.
+
+`maxEventSize` limits pending parser text, measured in JavaScript string code units. It is neither
+a network byte limit nor a maximum decoded payload size: in installed Effect, a complete event
+that is parsed within one input chunk can clear pending state before that limit check. The proof
+deliberately splits a pending event before its terminator to demonstrate the control. No adapter
+parser replacement or stronger size guarantee is added.

+
+The generated client acquisition Effect requires declared request encoding and response decoding
+services, declared error/middleware services, and any additional client requirements. A serviceful
+SSE event decoder is captured in the acquisition Context by public `HttpApiClient`; its resulting
+Stream advertises `never` residual services. The retained compile fixture proves those channels,
+including a caller's additional error/service types and declared stream errors. A caller-supplied
+ready client must satisfy that public interface; the adapter does not erase requirements to make
+construction compile.
+
+Public `Stream.toAsyncIterable` closes its scope and interrupts pending pulls on `return()`.
+The proof observes one Web body cancellation and an aborted transport signal both when returning
+after the first event and when aborting consumption. These observations do not transfer ownership
+of the acquired client, runtime, or application Scope to the adapter. Upstream transport remains
+responsible for resources when acquisition fails before a usable Stream is returned.
+
+Buffered metadata uses `decoded-and-response` so normal buffering/decoding finishes before the
+metadata record is returned. Copy raw enumerable string entries into an ordinary frozen record;
+never cache `HttpClientResponse`, Web `Response`, Effect `Headers`, cookies, or an open body. Do not
+use `Headers.toJSON`, which applies redaction rather than copying raw strings. Decoded data retains
+its declared representation and ownership; freeze only the new metadata envelope and plain header
+snapshot. Applications choose whether those headers may be persisted or dehydrated.
+
+Raw-byte proof observations show `[1, 2, 3]` returned as one transport chunk and as two chunks
+`[1, 2]`, `[3]`. Retention by chunk count therefore changes which bytes remain despite identical
+full-body content. Native byte Streams also retain transport/body lifetime until consumed or
+closed. The programme deliberately limits generated streaming views to schema-decoded SSE
+application records. Existing explicitly buffered byte schemas keep their existing behavior.
+
+## Executable evidence
+
+- [`tests/http-view-proof.test.ts`](../../tests/http-view-proof.test.ts) uses `HttpApiTest.groups`
+  with real handlers for finite SSE/event/header/error round trips, and public
+  `HttpApiClient.makeWith`/`HttpClient.make` for controlled wire and body-lifecycle observations.
+- [`tests/types/http-view-proof.ts`](../../tests/types/http-view-proof.ts) compiles upstream
+  acquisition, stream, decoded-wrapper, additional-client, and separated-request contracts. It
+  passes with installed TypeScript 5.9.3 and 7.0.2 without a registry installation.
+- `vp test tests/http-view-proof.test.ts` runs the focused runtime proof. Implementation tickets
+  must additionally verify their shipped builders through the agreed installed-tarball seam.
+
+Upstream evidence is available in the installed public `effect/http-api`, `effect/http`,
+`effect/encoding`, and `effect` exports. Source inspection used `HttpApiClient`'s stream decoding
+and captured Context, `HttpApiEndpoint`'s success validation/client channels, `HttpApiSchema`'s
+stream/wrapper declarations, `Sse`'s decoder controls, and the public iterator/HTTP finalization
+contracts. Re-run this evidence when the coordinated Effect patch changes.

+# RPC transport batching decision
+
+Keep transport policy in Effect and the application. The installed Effect 4.0.0 HTTP and socket
+protocols send one request envelope per independent call. A shared WebSocket removes repeated HTTP
+request headers and shares one connection, but it still sends each envelope separately. This
+measurement supports an application-owned multiplexed transport when request overhead matters;
+it does not justify an automatic batching engine in the RPC utility tree.
+
+## Reproduce the measurement
+
+Run the retained [protocol fixture](../examples/server/tests/rpc-transport-overhead.test.ts):
+
+```sh
+RPC_TRANSPORT_MEASURE=1 vp run --no-cache test examples/server/tests/rpc-transport-overhead.test.ts
+```
+
+The fixture uses the public package factory, a real QueryClient, public Effect clients/servers,
+and the existing server workspace's Node platform adapter. It runs 1, 8, and 32 concurrent unary
+queries with distinct integer payloads and empty caches. Each call returns its own integer; Query
+retries are disabled. Fixed request IDs and disabled RPC tracing make envelope sizes reproducible.
+No dependencies are installed.
+
+The October 9, 2026 baseline used Node 24.5.0, Effect and Node platform 4.0.0, Query Core 5.104.0,
+and Vite+ 1.0.0. Each row starts a fresh loopback host and ready client. HTTP uses FetchHttpClient
+with JSON serialization; WebSocket uses the installed Node WebSocket constructor with the same
+serialization. HTTP connection counts describe this concurrent HTTP/1.1 workload and the default
+fetch connection pool, rather than a requirement of the RPC protocol.
+

+For eight calls, multiplexing reduces measured client-to-server bytes by about 75%; at 32 calls,
+the reduction is about 80%. Envelope counts and envelope bytes remain equal. All calls produce
+separate successful cache entries.
+
+Byte counts come from encoded HTTP bodies, the actual request line and raw headers, actual
+WebSocket sends, and the server TCP sockets' `bytesRead`. WebSocket totals include one upgrade
+request and the six-byte masked frame overhead of each small request in this fixture. Counts end
+after responses arrive and before disposal. They exclude response traffic, TCP/IP packet headers,
+TLS, connection setup packets, and later keepalives. They measure bytes and calls, not latency,
+throughput, or CPU cost. Browser, HTTP/2, TLS, compression, warm connections, larger payloads, and
+remote backends require their own application measurement. Exact header bytes may change with the
+Node/fetch version or application headers.
+
+## Configure the layer that owns the cost

+
+Effect's HTTP client protocol encodes a single request and performs a single POST in
+`node_modules/effect/src/rpc/RpcClient.ts`, `makeProtocolHttp` (lines 937–949). The socket protocol
+shares a writer and routes responses by request ID, then encodes and writes each message separately
+in `makeProtocolSocket` (lines 1068–1072, 1103–1110, 1195–1204). The public WebSocket adapter maps
+each write to one `send` in `node_modules/effect/src/socket/Socket.ts` (lines 1128–1137).
+
+`node_modules/effect/src/rpc/RpcSerialization.ts` accepts JSON arrays and provides NDJSON/JSON-RPC
+framing. The HTTP server also accepts multiple decoded messages in one request
+(`RpcServer.ts`, lines 1160–1168). Those parsing capabilities do not collect independent calls in
+the stock ready client. No stock-client aggregation option is supported by this exact version.
+
+For backend batching, construct one shared `RequestResolver.make` in the server service, optionally
+set its collection delay with `RequestResolver.setDelay`, invoke a backend bulk operation for the
+collected IDs, and complete every entry with its individual Exit. Handlers use
+`Effect.request(request, resolver)`. Sharing the resolver is essential: its instance and batch key
+own collection, and a delay adds latency before backend execution. The installed primary-source
+recipe is `node_modules/effect/ai-docs/src/05_batching/10_request-resolver.ts` (lines 39–73); resolver
+collection lives in `node_modules/effect/src/internal/request.ts` (lines 82–98, 116–165).
+
+Query Core's `node_modules/@tanstack/query-core/src/notifyManager.ts` batches notification
+callbacks (lines 32–73, 100–113). This does not aggregate requests or replace individual cache
+writes. A policy that batches streamed Query data publication addresses another cost and must
+define its own delivery and cancellation behavior.
+
+## Keep the ready client alive
+
+The fixture demonstrates the supported socket ownership recipe: acquire the Socket, build
+`RpcClient.layerProtocolSocket()` with serialization into the application's client Scope using
+`Layer.buildWithScope`, and acquire `RpcClient.make(..., { flatten: true })` with that Context and
+Scope. Pass the resulting ready RPC client to `createRpcQueryUtils`. Finish/cancel its queries and
+close the client Scope before closing the host. The package acquires or disposes none of these
+resources, as required by [ADR 0007](adr/0007-keep-the-core-factory-lifecycle-neutral.md).
+
+Providing a socket protocol Layer only around the acquisition Effect closes its receive-loop
+resources when that Effect returns. Keep the Layer's Scope alive for all later calls. The fixture
+closes its explicitly owned client Scope and loopback listener on every run.
+
+The bounded decision is to retain ordinary independent Query execution. Applications can choose
+the proven shared WebSocket transport when repeated HTTP overhead matters, declare an explicit
+bulk operation when their domain supports one, or batch backend work with RequestResolver. A
+generic HTTP collection window has no stock-client support here and would introduce latency,
+failure, cancellation, and retry policy that belongs to the application.

+# Keep RPC transport aggregation in the application
+
+Status: Accepted. Extends [ADR 0007](0007-keep-the-core-factory-lifecycle-neutral.md).
+
+## Context
+
+Independent ready RPC client calls can incur repeated HTTP headers and connection overhead. A
+shared WebSocket can reduce that cost while preserving individual request envelopes, responses,
+failures, and cancellation.
+
+## Decision
+
+The application selects and owns the transport. Keep independent Query execution in the RPC
+utility tree. Use a shared WebSocket when repeated HTTP overhead matters, or declare an explicit
+bulk RPC when the domain supports one. A collecting custom protocol must own its collection delay,
+response routing, retries, failures, interruption, and lifetime.
+
+Transport aggregation, backend RequestResolver batching, and Query publication address separate
+costs. A shared server RequestResolver can combine backend lookups while frontend RPC requests
+remain independent. Query notification batching changes callback scheduling; streamed publication
+batching changes cache update frequency. Neither reduces transport request count.
+
+Effect 4.0.0's stock HTTP protocol performs one POST per Request in
+`node_modules/effect/src/rpc/RpcClient.ts`, `makeProtocolHttp`. Its `makeProtocolSocket` shares a
+writer and routes responses by request ID, then writes each encoded message separately. The
+WebSocket adapter's writer maps each write to one send in `node_modules/effect/src/socket/Socket.ts`.
+JSON array/framing support in `RpcSerialization.ts` and batch input parsing in `RpcServer.ts`
+provide no stock-client collection window.
+
+## Measurement
+
+The [protocol fixture](../../examples/server/tests/rpc-transport-overhead.test.ts) uses real loopback
+Effect HTTP/WebSocket servers, ready clients, the public package factory, and a real QueryClient.
+Each row starts a fresh host, client, and cache, then runs concurrent unary queries with distinct
+integer payloads. JSON serialization, fixed request IDs, disabled RPC tracing, and disabled Query
+retries keep the request sizes comparable.
+
+```sh
+RPC_TRANSPORT_MEASURE=1 vp run --no-cache test examples/server/tests/rpc-transport-overhead.test.ts
+```
+
+The October 9, 2026 measurement used Node 24.5.0, Effect and Node platform 4.0.0, Query Core 5.104.0,
+and Vite+ 1.0.0.

+
+At eight calls, WebSocket multiplexing reduces outbound bytes by about 75% while retaining eight
+envelopes and eight sends. At 32 calls the reduction is about 80%. Each query returns its individual
+value and creates a separate successful cache entry.
+
+Counts use encoded HTTP bodies, actual request lines/raw headers, WebSocket sends, and server TCP
+`bytesRead`. WebSocket totals include one upgrade and six masked-frame bytes per small request.
+Counts end after responses arrive and before disposal. Responses, TCP/IP headers, TLS, connection
+setup packets, and later keepalives are excluded. This measures bytes and requests, not latency,
+throughput, or CPU cost. HTTP connection counts reflect this cold concurrent HTTP/1.1 fetch pool;
+warm connections, HTTP/2, browsers, compression, larger payloads, and remote backends need their own
+measurement. Header sizes depend on the Node/fetch version and application headers.
+
+## Consequences
+
+Acquire the socket, build its protocol Layer into an application-owned client Scope with
+`Layer.buildWithScope`, and acquire the flat client with that Context and Scope. Keep the Scope
+alive while the utility tree uses the ready RPC client. Close the client Scope before its host;
+providing the socket protocol Layer only around acquisition closes its receive loop too early.
+
+For backend batching, share one `RequestResolver.make` instance in the server service, optionally
+set a collection delay with `RequestResolver.setDelay`, run the backend bulk operation, and complete
+each entry with its individual Exit. Handlers call `Effect.request(request, resolver)`. The installed
+recipe is `node_modules/effect/ai-docs/src/05_batching/10_request-resolver.ts`; collection belongs to
+the shared resolver instance and batch key. A collection delay adds latency.
+
+The package retains its lifecycle-neutral ready-client boundary and adds no automatic transport
+batching API.

-# RPC transport batching decision
-
-Keep transport policy in Effect and the application. The installed Effect 4.0.0 HTTP and socket
-protocols send one request envelope per independent call. A shared WebSocket removes repeated HTTP
-request headers and shares one connection, but it still sends each envelope separately. This
-measurement supports an application-owned multiplexed transport when request overhead matters;
-it does not justify an automatic batching engine in the RPC utility tree.
-
-## Reproduce the measurement
-
-Run the retained [protocol fixture](../examples/server/tests/rpc-transport-overhead.test.ts):
-
-```sh
-RPC_TRANSPORT_MEASURE=1 vp run --no-cache test examples/server/tests/rpc-transport-overhead.test.ts
-```
-
-The fixture uses the public package factory, a real QueryClient, public Effect clients/servers,
-and the existing server workspace's Node platform adapter. It runs 1, 8, and 32 concurrent unary
-queries with distinct integer payloads and empty caches. Each call returns its own integer; Query
-retries are disabled. Fixed request IDs and disabled RPC tracing make envelope sizes reproducible.
-No dependencies are installed.
-
-The October 9, 2026 baseline used Node 24.5.0, Effect and Node platform 4.0.0, Query Core 5.104.0,
-and Vite+ 1.0.0. Each row starts a fresh loopback host and ready client. HTTP uses FetchHttpClient
-with JSON serialization; WebSocket uses the installed Node WebSocket constructor with the same
-serialization. HTTP connection counts describe this concurrent HTTP/1.1 workload and the default
-fetch connection pool, rather than a requirement of the RPC protocol.

-For eight calls, multiplexing reduces measured client-to-server bytes by about 75%; at 32 calls,
-the reduction is about 80%. Envelope counts and envelope bytes remain equal. All calls produce
-separate successful cache entries.
-
-Byte counts come from encoded HTTP bodies, the actual request line and raw headers, actual
-WebSocket sends, and the server TCP sockets' `bytesRead`. WebSocket totals include one upgrade
-request and the six-byte masked frame overhead of each small request in this fixture. Counts end
-after responses arrive and before disposal. They exclude response traffic, TCP/IP packet headers,
-TLS, connection setup packets, and later keepalives. They measure bytes and calls, not latency,
-throughput, or CPU cost. Browser, HTTP/2, TLS, compression, warm connections, larger payloads, and
-remote backends require their own application measurement. Exact header bytes may change with the
-Node/fetch version or application headers.

-
-Effect's HTTP client protocol encodes a single request and performs a single POST in
-`node_modules/effect/src/rpc/RpcClient.ts`, `makeProtocolHttp` (lines 937–949). The socket protocol
-shares a writer and routes responses by request ID, then encodes and writes each message separately
-in `makeProtocolSocket` (lines 1068–1072, 1103–1110, 1195–1204). The public WebSocket adapter maps
-each write to one `send` in `node_modules/effect/src/socket/Socket.ts` (lines 1128–1137).
-
-`node_modules/effect/src/rpc/RpcSerialization.ts` accepts JSON arrays and provides NDJSON/JSON-RPC
-framing. The HTTP server also accepts multiple decoded messages in one request
-(`RpcServer.ts`, lines 1160–1168). Those parsing capabilities do not collect independent calls in
-the stock ready client. No stock-client aggregation option is supported by this exact version.
-
-For backend batching, construct one shared `RequestResolver.make` in the server service, optionally
-set its collection delay with `RequestResolver.setDelay`, invoke a backend bulk operation for the
-collected IDs, and complete every entry with its individual Exit. Handlers use
-`Effect.request(request, resolver)`. Sharing the resolver is essential: its instance and batch key
-own collection, and a delay adds latency before backend execution. The installed primary-source
-recipe is `node_modules/effect/ai-docs/src/05_batching/10_request-resolver.ts` (lines 39–73); resolver
-collection lives in `node_modules/effect/src/internal/request.ts` (lines 82–98, 116–165).
-
-Query Core's `node_modules/@tanstack/query-core/src/notifyManager.ts` batches notification
-callbacks (lines 32–73, 100–113). This does not aggregate requests or replace individual cache
-writes. A policy that batches streamed Query data publication addresses another cost and must
-define its own delivery and cancellation behavior.
-
-## Keep the ready client alive
-
-The fixture demonstrates the supported socket ownership recipe: acquire the Socket, build
-`RpcClient.layerProtocolSocket()` with serialization into the application's client Scope using
-`Layer.buildWithScope`, and acquire `RpcClient.make(..., { flatten: true })` with that Context and
-Scope. Pass the resulting ready RPC client to `createRpcQueryUtils`. Finish/cancel its queries and
-close the client Scope before closing the host. The package acquires or disposes none of these
-resources, as required by [ADR 0007](adr/0007-keep-the-core-factory-lifecycle-neutral.md).
-
-Providing a socket protocol Layer only around the acquisition Effect closes its receive-loop
-resources when that Effect returns. Keep the Layer's Scope alive for all later calls. The fixture
-closes its explicitly owned client Scope and loopback listener on every run.
-
-The bounded decision is to retain ordinary independent Query execution. Applications can choose
-the proven shared WebSocket transport when repeated HTTP overhead matters, declare an explicit
-bulk operation when their domain supports one, or batch backend work with RequestResolver. A
-generic HTTP collection window has no stock-client support here and would introduce latency,
-failure, cancellation, and retry policy that belongs to the application.

 # Project HTTP streams and buffered metadata into separate cached views
 
-Status: Accepted design for the review programme. Implementation follows in issues #104–#106.
-Amends [ADR 0020](0020-generate-accumulated-and-live-stream-queries.md),
+Status: Accepted. Amends [ADR 0020](0020-generate-accumulated-and-live-stream-queries.md),
 [ADR 0022](0022-add-buffered-http-utilities-with-separate-key-roots.md), and
 [ADR 0023](0023-expose-buffered-multipart-http-mutations.md).
 
+## Context
+
+A query cache needs decoded application values with stable identity. SSE declarations provide
+such values; raw transport chunks do not. Buffered responses can also expose status and headers
+without retaining a response object or its resources.
+
 ## Decision
 
-An endpoint with exactly one success alternative, whose body is `HttpApiSchema.StreamSse`,
-exposes accumulated and live query builders. A declared `WithHeaders` wrapper projects onto each
-emitted chunk: `HttpApiSchema.withHeaders({ body: chunk, headers: decodedHeaders })`. Accumulated
-query data is an array of those values; live query data is the latest value. Neither view caches a
-Stream or a response object. An unwrapped successful live `undefined` becomes `null`; an accumulated
-`undefined` element or a declared wrapper containing it keeps its original representation.
-
-Keep the existing `streamedKey`/`streamedOptions` and `liveKey`/`liveOptions` vocabulary. Accept
-`sseOptions` beside `input` in option builders and beside the retention policy in concrete key
-builders. Decoded request input and custom key-encoder input contain only declared request parts.
-Normalize the installed decoder's `maxEventSize` default to 10 MiB of string code units. Its
-effective value belongs in both concrete view keys because it changes successful consumption into
-a failure for sufficiently large pending events. Accumulated identity also includes effective
-`maxChunks` and `refetchMode`. Key-prefix invalidation remains independent of those concrete policies.
-
-Expose `metadataKey`/`metadataOptions` on query-enabled buffered endpoints. Execute the ready
-client with `responseMode: 'decoded-and-response'` and return a readonly, frozen outer record
-`{ data, status, headers }`, with copied, frozen plain string headers. Normalize decoded `undefined`
-to `null` in `data`; preserve any declared decoded `WithHeaders` value intact. Give this view its
-own `metadata` operation identity. Ordinary query, infinite-query, and mutation behavior stays as
-specified by the existing buffered contracts. Header copying reads raw string entries rather than
-Effect's redacting `Headers.toJSON` representation.
-
-The supplied ready client and runner own encoding, middleware, residual services, and transport.
-Acquire the SSE value and consume it under the caller's runner Context; forward Query's abort
-signal and close the iterator on cancellation. Both acquisition and consumption failures retain
-the complete Cause in `EffectHttpApiQueryError`, with `streamed`, `live`, or `metadata` operation
-metadata. An independent interruption is a failure; signal cancellation follows native Query
-reversion. Empty accumulated completion succeeds with the appropriate retained history. Empty
-live completion raises `EffectHttpApiQueryEmptyStreamError` with declaration identity. Runner
-rejections pass through unchanged.
-
-## Supported limits
-
-Effect 4.0.0 permits only one streaming success alternative, but it can combine that alternative
-with buffered successes selected by status/content type. Such a ready client can return either
-buffered data or a Stream. Keep the whole mixed endpoint omitted: assigning a stream view or a
-buffered view would misrepresent one successful outcome. Revisit only with an explicitly proved
-discriminated contract. Streaming multipart request payloads remain omitted. Buffered multipart
-requests remain mutation-only when their successes are buffered; they do not gain SSE query views.
-
-Keep raw `StreamUint8Array` successes omitted, including wrappers and mixed alternatives. Transport
-chunks partition the same bytes differently, and `maxChunks` counts transport chunks rather than
-bytes or application records. A latest-chunk cache is not a download snapshot. Applications can
-consume the native ready client into their own sink or declare an explicitly buffered byte result;
-this programme adds no generic download accumulator or sink ownership.
-
-SSE event declarations preserve their declared event fields and IDs; data declarations emit only
-decoded data. The adapter does not reconstruct dropped event IDs, reconnect, retry a parser
-directive, or invent resume semantics. `Sse.Retry`, its `lastEventId`, and all other failures remain
-available in the Cause for an application-owned retry/resume policy.
-
-The [support matrix and proof](../design/http-cached-views.md) record the exact upstream seam,
-service channels, resource behavior, and executable evidence behind this decision.
+Generate accumulated and live query builders for endpoints with exactly one SSE success
+alternative. A declared `WithHeaders` wrapper projects onto each emission as
+`HttpApiSchema.withHeaders({ body: chunk, headers: decodedHeaders })`. Accumulated data is an array
+of emissions; live data is the latest emission. Data declarations emit decoded data, while event
+declarations preserve their declared fields, event names, and IDs.
+
+Expose opt-in `metadataKey` and `metadataOptions` on query-enabled buffered endpoints. Execute the
+ready client with `responseMode: 'decoded-and-response'` and return a frozen readonly envelope:
+`{ readonly data: QueryData<DecodedSuccess>; readonly status: number; readonly headers: Readonly<Record<string, string>> }`.
+Copy raw enumerable string headers into an ordinary frozen record. Preserve declared decoded
+`WithHeaders` values inside `data`; normalize only a top-level successful `undefined` to `null`.
+Metadata uses its own operation identity and the ordinary query options' selection, initial-data,
+skip-token, and error inference. It adds no metadata mutation or infinite-query methods.
+
+### Supported declarations
+
+Request and success rows compose: the request must permit the view, and the success must have
+that representation. HTTP method does not determine cache capability.

+
+Effect 4.0.0 permits one streaming success alternative with additional buffered alternatives
+selected by status/content type. Keep such mixed endpoints omitted until a discriminated contract
+can represent every successful outcome.
+
+For ordinary queries and unwrapped live values, successful top-level `undefined` becomes `null`.
+Accumulated arrays preserve `undefined` elements. Decoded wrappers and their fields keep their
+original representation. Live completion preserves the latest value; completion without an
+emission raises `EffectHttpApiQueryEmptyStreamError` with declaration identity. Empty accumulated
+completion succeeds with the appropriate retained history.
+
+### View identity
+
+Streaming leaves provide `key`, `streamedKey`, `streamedOptions`, `liveKey`, and `liveOptions`.
+Option builders accept `sseOptions?: Sse.DecodeOptions` beside `input`; accumulated builders also
+accept `maxChunks` and `refetchMode`. Concrete key builders accept the same policy after decoded
+input, or as their only argument for inputless endpoints. Live key policy contains decoder controls
+only. Endpoint prefixes select every concrete policy.
+
+Decoded request input and custom key-encoder input contain only declared request parts. Response
+mode belongs to the adapter; decoder controls belong to the view. Declared transport headers,
+including an application resume cursor, remain request identity input. Middleware-owned identity
+belongs in the caller's key prefix. Captured request values remain immutable so identity and
+execution describe the same request.
+
+The decoder's `maxEventSize` default is 10 MiB of JavaScript string code units. Absent options,
+an empty record, an undefined field, and an explicit default share normalized identity. A
+non-default effective limit splits both SSE view keys. Require a positive safe integer and reject
+invalid values synchronously with a configuration error. Pass the same normalized value to the
+ready client. Accumulated identity also includes effective `maxChunks` and `refetchMode`.
+
+`maxEventSize` limits pending parser text, rather than network bytes or decoded payload size.
+A complete event parsed within one input chunk can clear pending state before Effect checks the
+limit. A pending event split before its terminator demonstrates the actual control; the adapter
+retains that upstream guarantee.
+
+### Failures and resource lifetime

+| Empty successful SSE completion                                | Empty Stream                            | Accumulated empty/history result; live empty-stream error       |

+
+Acquisition requires declared encoding, response decoding, error, and middleware services, plus
+additional client requirements. Public `HttpApiClient` captures an SSE decoder's services in the
+acquisition Context; the resulting Stream advertises `never` residual services. A ready client
+must satisfy that public interface, including additional error and service channels.
+
+The supplied ready client and runner own transport, middleware, runtime, and Scope. Acquire and
+consume SSE under the caller's runner Context, forward Query's abort signal, and close the iterator
+on cancellation. Acquisition and consumption failures preserve the complete Cause in
+`EffectHttpApiQueryError` with `streamed`, `live`, or `metadata` operation identity. Independent
+interruption is a failure; signal cancellation follows native Query reversion.
+
+Public `Stream.toAsyncIterable` closes its scope and interrupts pending pulls on `return()`.
+Returning after the first event and aborting consumption each cancel the Web body once and abort
+the transport signal. Upstream transport retains responsibility when acquisition fails before a
+usable Stream is returned.
+
+Buffered metadata finishes buffering and decoding before returning its envelope. Cache only that
+envelope and header snapshot, never `HttpClientResponse`, Web `Response`, Effect `Headers`, a cookie
+collection, or an open body. `Headers.toJSON` applies redaction, so it cannot produce the required
+raw snapshot. Decoded data retains its declared representation and ownership. Applications choose
+whether raw headers may be persisted or dehydrated.
+
+## Consequences
+
+Raw byte partitions depend on transport chunking: `[1, 2, 3]` can arrive as one chunk or as
+`[1, 2]`, `[3]`. Retention by chunk count therefore changes retained bytes despite identical body
+content, and native byte Streams retain body lifetime until consumed or closed. Applications own
+download accumulation and sinks; explicitly buffered byte schemas keep their existing behavior.
+
+The adapter preserves declared event fields and IDs. Application code owns reconnection,
+`Sse.Retry` handling, and resume semantics, including use of its `lastEventId`.
+
+## Evidence
+
+- [`tests/http-view-proof.test.ts`](../../tests/http-view-proof.test.ts) uses public
+  `HttpApiTest.groups`, `HttpApiClient.makeWith`, and `HttpClient.make` for decoded SSE, headers,
+  reserved failures, retry directives, parser limits, raw byte partitions, and body finalization.
+- [`tests/types/http-view-proof.ts`](../../tests/types/http-view-proof.ts) verifies acquisition and
+  stream channels, decoded wrappers, additional client requirements, and separated request controls
+  with TypeScript 5.9 and the repository compiler.
+
+The upstream contracts come from `HttpApiClient` stream decoding and captured Context,
+`HttpApiEndpoint` success validation and client channels, `HttpApiSchema` declarations, `Sse`
+decoder controls, and public iterator and HTTP finalization. Reverify them when the exact Effect
+peer changes.

-and rejects weakened quarantine settings. Preserve `--ignore-scripts` for packed consumers.
-Locally built project tarballs are repository artifacts; their registry dependencies still need
-to satisfy the quarantine.
-
-When an install fails, record the rejected version, registry publication time, and earliest
-eligibility time. A missing publication time remains a blocking condition. Continue independent
-work using already-installed dependencies read-only. Do not weaken the policy to unblock work.
-
-Run `vp run install-policy` after changes to installation policy or consumer setup. This invokes
-the real pnpm CLI against an isolated fixture registry and checks fresh resolution plus frozen
-installs with cached artifacts, including under-age and missing-time rejection. The normal packed
-consumer checks verify real eligible registry dependencies with the same copied policy.
-
-After publishing a new package version, registry installation waits for that version's own
-seven-day eligibility. Metadata and provenance checks and local-tarball acceptance may run sooner.

-# HTTP cached-view contract and design proof
-
-This is the implementation contract for issues #104–#106 under spec #95. The retained proof uses
-the already installed Effect 4.0.0 public exports. It does not install dependencies or add shipped
-features. [ADR 0024](../adr/0024-project-http-streams-and-buffered-metadata.md) records the decision.
-
-## Input and output support matrix
-
-The request and success rows compose: a request must permit a particular view and its success
-must have the corresponding representation. HTTP method does not determine cache capability.

-
-For ordinary query data and live values, successful top-level `undefined` becomes `null`.
-Accumulated arrays preserve `undefined` elements. Metadata normalizes its decoded `data` field;
-it leaves a decoded wrapper and its fields unchanged. Live completion preserves the latest value;
-completion without any emission is a distinct package empty-stream error.
-
-## Concrete interface
-
-Streaming leaves provide `key()`, `streamedKey(...)`, `streamedOptions(...)`, `liveKey(...)`, and
-`liveOptions(...)`. Query-enabled buffered leaves additionally provide `metadataKey(...)` and
-`metadataOptions(...)`. The metadata result shape is
-`{ readonly data: QueryData<DecodedSuccess>; readonly status: number; readonly headers: Readonly<Record<string, string>> }`.
-Metadata gets the normal unary options' native selection, initial-data, skip-token, and error
-inference with this result shape. It does not create metadata mutation or infinite-query methods.
-
-Option builders accept `sseOptions?: Sse.DecodeOptions` alongside `input`, with accumulated
-`maxChunks` and `refetchMode` alongside it. Concrete key builders accept the same policy object
-after decoded input, or as their only argument for inputless endpoints. Live concrete key policy
-contains only decoder controls. Prefix keys continue to select every policy for that endpoint.
-
-The installed decoder has one control, `maxEventSize`. Absent options, an empty options record,
-an undefined field, and the explicit 10 MiB default must have identical normalized identity. A
-non-default effective limit splits both SSE views. Require a positive safe integer and reject
-invalid values synchronously with a configuration error. This protects finite, JSON-safe view
-identity. The same normalized value must be passed to the ready client.
-
-`maxEventSize` limits pending parser text, measured in JavaScript string code units. It is neither
-a network byte limit nor a maximum decoded payload size: in installed Effect, a complete event
-that is parsed within one input chunk can clear pending state before that limit check. The proof
-deliberately splits a pending event before its terminator to demonstrate the control. No adapter
-parser replacement or stronger size guarantee is added.
-

-
-The generated client acquisition Effect requires declared request encoding and response decoding
-services, declared error/middleware services, and any additional client requirements. A serviceful
-SSE event decoder is captured in the acquisition Context by public `HttpApiClient`; its resulting
-Stream advertises `never` residual services. The retained compile fixture proves those channels,
-including a caller's additional error/service types and declared stream errors. A caller-supplied
-ready client must satisfy that public interface; the adapter does not erase requirements to make
-construction compile.
-
-Public `Stream.toAsyncIterable` closes its scope and interrupts pending pulls on `return()`.
-The proof observes one Web body cancellation and an aborted transport signal both when returning
-after the first event and when aborting consumption. These observations do not transfer ownership
-of the acquired client, runtime, or application Scope to the adapter. Upstream transport remains
-responsible for resources when acquisition fails before a usable Stream is returned.
-
-Buffered metadata uses `decoded-and-response` so normal buffering/decoding finishes before the
-metadata record is returned. Copy raw enumerable string entries into an ordinary frozen record;
-never cache `HttpClientResponse`, Web `Response`, Effect `Headers`, cookies, or an open body. Do not
-use `Headers.toJSON`, which applies redaction rather than copying raw strings. Decoded data retains
-its declared representation and ownership; freeze only the new metadata envelope and plain header
-snapshot. Applications choose whether those headers may be persisted or dehydrated.
-
-Raw-byte proof observations show `[1, 2, 3]` returned as one transport chunk and as two chunks
-`[1, 2]`, `[3]`. Retention by chunk count therefore changes which bytes remain despite identical
-full-body content. Native byte Streams also retain transport/body lifetime until consumed or
-closed. The programme deliberately limits generated streaming views to schema-decoded SSE
-application records. Existing explicitly buffered byte schemas keep their existing behavior.
-
-## Executable evidence
-
-- [`tests/http-view-proof.test.ts`](../../tests/http-view-proof.test.ts) uses `HttpApiTest.groups`
-  with real handlers for finite SSE/event/header/error round trips, and public
-  `HttpApiClient.makeWith`/`HttpClient.make` for controlled wire and body-lifecycle observations.
-- [`tests/types/http-view-proof.ts`](../../tests/types/http-view-proof.ts) compiles upstream
-  acquisition, stream, decoded-wrapper, additional-client, and separated-request contracts. It
-  passes with installed TypeScript 5.9.3 and 7.0.2 without a registry installation.
-- `vp test tests/http-view-proof.test.ts` runs the focused runtime proof. Implementation tickets
-  must additionally verify their shipped builders through the agreed installed-tarball seam.
-
-Upstream evidence is available in the installed public `effect/http-api`, `effect/http`,
-`effect/encoding`, and `effect` exports. Source inspection used `HttpApiClient`'s stream decoding
-and captured Context, `HttpApiEndpoint`'s success validation/client channels, `HttpApiSchema`'s
-stream/wrapper declarations, `Sse`'s decoder controls, and the public iterator/HTTP finalization
-contracts. Re-run this evidence when the coordinated Effect patch changes.

+TanStack's abort signal and close the AsyncIterator on cancellation. A stream failure preserves its
+complete Cause in `EffectRpcQueryError`, including interruption-only and mixed interruption/defect
+Causes, while that signal is not aborted. Requested cancellation retains TanStack's native result
+and cache reversion, including superseded refetches and removal of the last observer.
 The application owns client/runtime resources, transport, middleware, Scope, QueryClient, and
 framework lifecycle. SSR dehydrates completed data normally; open streams require cancellation
 after the first successful snapshot. Mutations have no cancellation signal.

 # Project HTTP streams and buffered metadata into separate cached views
 
-Status: Accepted. Amends [ADR 0020](0020-generate-accumulated-and-live-stream-queries.md),
-[ADR 0022](0022-add-buffered-http-utilities-with-separate-key-roots.md), and
-[ADR 0023](0023-expose-buffered-multipart-http-mutations.md).
-
-## Context
-
-A query cache needs decoded application values with stable identity. SSE declarations provide
-such values; raw transport chunks do not. Buffered responses can also expose status and headers
-without retaining a response object or its resources.
-
-## Decision
-
-Generate accumulated and live query builders for endpoints with exactly one SSE success
-alternative. A declared `WithHeaders` wrapper projects onto each emission as
-`HttpApiSchema.withHeaders({ body: chunk, headers: decodedHeaders })`. Accumulated data is an array
-of emissions; live data is the latest emission. Data declarations emit decoded data, while event
-declarations preserve their declared fields, event names, and IDs.
-
-Expose opt-in `metadataKey` and `metadataOptions` on query-enabled buffered endpoints. Execute the
-ready client with `responseMode: 'decoded-and-response'` and return a frozen readonly envelope:
-`{ readonly data: QueryData<DecodedSuccess>; readonly status: number; readonly headers: Readonly<Record<string, string>> }`.
-Copy raw enumerable string headers into an ordinary frozen record. Preserve declared decoded
-`WithHeaders` values inside `data`; normalize only a top-level successful `undefined` to `null`.
-Metadata uses its own operation identity and the ordinary query options' selection, initial-data,
-skip-token, and error inference. It adds no metadata mutation or infinite-query methods.
-
-### Supported declarations
-
-Request and success rows compose: the request must permit the view, and the success must have
-that representation. HTTP method does not determine cache capability.

-
-Effect 4.0.0 permits one streaming success alternative with additional buffered alternatives
-selected by status/content type. Keep such mixed endpoints omitted until a discriminated contract
-can represent every successful outcome.
-
-For ordinary queries and unwrapped live values, successful top-level `undefined` becomes `null`.
-Accumulated arrays preserve `undefined` elements. Decoded wrappers and their fields keep their
-original representation. Live completion preserves the latest value; completion without an
-emission raises `EffectHttpApiQueryEmptyStreamError` with declaration identity. Empty accumulated
-completion succeeds with the appropriate retained history.
-
-### View identity
-
-Streaming leaves provide `key`, `streamedKey`, `streamedOptions`, `liveKey`, and `liveOptions`.
-Option builders accept `sseOptions?: Sse.DecodeOptions` beside `input`; accumulated builders also
-accept `maxChunks` and `refetchMode`. Concrete key builders accept the same policy after decoded
-input, or as their only argument for inputless endpoints. Live key policy contains decoder controls
-only. Endpoint prefixes select every concrete policy.
-
-Decoded request input and custom key-encoder input contain only declared request parts. Response
-mode belongs to the adapter; decoder controls belong to the view. Declared transport headers,
-including an application resume cursor, remain request identity input. Middleware-owned identity
-belongs in the caller's key prefix. Captured request values remain immutable so identity and
-execution describe the same request.
-
-The decoder's `maxEventSize` default is 10 MiB of JavaScript string code units. Absent options,
-an empty record, an undefined field, and an explicit default share normalized identity. A
-non-default effective limit splits both SSE view keys. Require a positive safe integer and reject
-invalid values synchronously with a configuration error. Pass the same normalized value to the
-ready client. Accumulated identity also includes effective `maxChunks` and `refetchMode`.
-
-`maxEventSize` limits pending parser text, rather than network bytes or decoded payload size.
-A complete event parsed within one input chunk can clear pending state before Effect checks the
-limit. A pending event split before its terminator demonstrates the actual control; the adapter
-retains that upstream guarantee.
-
-### Failures and resource lifetime

-| Injected runner rejects                                        | Rejected Promise                        | Preserve rejection unchanged                                    |
-
-Acquisition requires declared encoding, response decoding, error, and middleware services, plus
-additional client requirements. Public `HttpApiClient` captures an SSE decoder's services in the
-acquisition Context; the resulting Stream advertises `never` residual services. A ready client
-must satisfy that public interface, including additional error and service channels.
-
-The supplied ready client and runner own transport, middleware, runtime, and Scope. Acquire and
-consume SSE under the caller's runner Context, forward Query's abort signal, and close the iterator
-on cancellation. Acquisition and consumption failures preserve the complete Cause in
-`EffectHttpApiQueryError` with `streamed`, `live`, or `metadata` operation identity. Independent
-interruption is a failure; signal cancellation follows native Query reversion.
-
-Public `Stream.toAsyncIterable` closes its scope and interrupts pending pulls on `return()`.
-Returning after the first event and aborting consumption each cancel the Web body once and abort
-the transport signal. Upstream transport retains responsibility when acquisition fails before a
-usable Stream is returned.
-
-Buffered metadata finishes buffering and decoding before returning its envelope. Cache only that
-envelope and header snapshot, never `HttpClientResponse`, Web `Response`, Effect `Headers`, a cookie
-collection, or an open body. `Headers.toJSON` applies redaction, so it cannot produce the required
-raw snapshot. Decoded data retains its declared representation and ownership. Applications choose
-whether raw headers may be persisted or dehydrated.
-
-## Consequences
-
-Raw byte partitions depend on transport chunking: `[1, 2, 3]` can arrive as one chunk or as
-`[1, 2]`, `[3]`. Retention by chunk count therefore changes retained bytes despite identical body
-content, and native byte Streams retain body lifetime until consumed or closed. Applications own
-download accumulation and sinks; explicitly buffered byte schemas keep their existing behavior.
-
-The adapter preserves declared event fields and IDs. Application code owns reconnection,
-`Sse.Retry` handling, and resume semantics, including use of its `lastEventId`.
-
-## Evidence
-
-- [`tests/http-view-proof.test.ts`](../../tests/http-view-proof.test.ts) uses public
-  `HttpApiTest.groups`, `HttpApiClient.makeWith`, and `HttpClient.make` for decoded SSE, headers,
-  reserved failures, retry directives, parser limits, raw byte partitions, and body finalization.
-- [`tests/types/http-view-proof.ts`](../../tests/types/http-view-proof.ts) verifies acquisition and
-  stream channels, decoded wrappers, additional client requirements, and separated request controls
-  with TypeScript 5.9 and the repository compiler.
-
-The upstream contracts come from `HttpApiClient` stream decoding and captured Context,
-`HttpApiEndpoint` success validation and client channels, `HttpApiSchema` declarations, `Sse`
-decoder controls, and public iterator and HTTP finalization. Reverify them when the exact Effect
-peer changes.

-Effect 4.0.0 exposes `RpcServer.makeNoSerialization` and
-`RpcClient.makeNoSerialization` as public constructors for decoded message
-channels. An application may connect their write callbacks within its own
-Scope, supply the server handler and middleware Context, and pass the resulting
-flat ready client to `createRpcQueryUtils`. Server-local execution therefore
-needs no loopback request or library-owned client factory. The browser keeps
-its independently scoped HTTP or socket client.
-
-Use a separate connection and QueryClient for each request identity. The
-server-owned handler Context determines services and authority; validate
-request headers in middleware. Capture the application's server Context during
-construction and provide it to every `server.write` call. Native dispatch merges
-the handler Context with its current fiber Context; dispatching directly from a
-caller runner permits that runner's services to override handler-owned services.
-The proof supplies conflicting runner identities to both concurrent clients and
-preserves their server-owned identities. Caller Context and explicit native call
-Context stay outside the authority-owning dispatch boundary. Keep stream
-acknowledgements enabled, and set the server's
-`disableFatalDefects: true` to preserve complete failed Exits rather than
-collapsing fatal defect Causes. Cancel queries before closing the caller-owned
-Scope.
-
-This route constructs payloads and carries decoded values, middleware headers,
-Exits, acknowledgements, and interrupts. It deliberately performs no transport
-Schema encoding or decoding. Native call types retain residual Schema service
-requirements, so the adapter still requires the application's matching runner;
-this does not prove that codec effects execute on a decoded channel. Applications
-that require wire validation or codec side effects should keep the schema-aware
-`RpcClient.make` protocol. An application-owned `FetchHttpClient.Fetch` can
-dispatch that protocol to its existing Web handler without a network request;
-that separate recipe must verify its own transport and resource semantics.
-
-The bounded executable proof is
-[`tests/create-rpc-query-utils-server-local.test.ts`](../../tests/create-rpc-query-utils-server-local.test.ts),
-with its application recipe in
-[`tests/fixtures/server-local-rpc.ts`](../../tests/fixtures/server-local-rpc.ts)
-and native service/type evidence in
-[`tests/types/server-local-client-contract.ts`](../../tests/types/server-local-client-contract.ts).
-It uses the public constructors directly, with the network fetch boundary
-disabled. It verifies decoded class behavior, payload defaults, authenticated
-request isolation, complete Causes, cancellation, finalization, and independent
-Scope disposal. `RpcTest` and `HttpApiTest` remain test support rather than
-production construction guarantees. The unstable upstream constructors remain
-qualified by the package's exact Effect peer.
-
-`vp run test` includes the native constructor contract through
-`vp run server-local-types`, using the repository compiler and TypeScript 5.9.
-Published adapter contracts remain covered by the existing packed consumers.
+Server rendering can execute local handlers without a network round trip. Applications may
+connect Effect's public decoded-message client and server within a request-owned Scope and pass
+the ready client to the adapter. This preserves the lifecycle-neutral boundary without adding a

-## Context
+Repeated RPC calls can incur substantial transport overhead. Keep transport selection and
+aggregation in the application because they determine connection lifetime, latency, routing,
+retries, and cancellation. Shared WebSocket transport reduces repeated headers while preserving
+independent calls; explicit bulk RPCs remain a domain choice.
 
-Independent ready RPC client calls can incur repeated HTTP headers and connection overhead. A
-shared WebSocket can reduce that cost while preserving individual request envelopes, responses,
-failures, and cancellation.
-
-## Decision
-
-The application selects and owns the transport. Keep independent Query execution in the RPC
-utility tree. Use a shared WebSocket when repeated HTTP overhead matters, or declare an explicit
-bulk RPC when the domain supports one. A collecting custom protocol must own its collection delay,
-response routing, retries, failures, interruption, and lifetime.
-
-Transport aggregation, backend RequestResolver batching, and Query publication address separate
-costs. A shared server RequestResolver can combine backend lookups while frontend RPC requests
-remain independent. Query notification batching changes callback scheduling; streamed publication
-batching changes cache update frequency. Neither reduces transport request count.
-
-Effect 4.0.0's stock HTTP protocol performs one POST per Request in
-`node_modules/effect/src/rpc/RpcClient.ts`, `makeProtocolHttp`. Its `makeProtocolSocket` shares a
-writer and routes responses by request ID, then writes each encoded message separately. The
-WebSocket adapter's writer maps each write to one send in `node_modules/effect/src/socket/Socket.ts`.
-JSON array/framing support in `RpcSerialization.ts` and batch input parsing in `RpcServer.ts`
-provide no stock-client collection window.
-
-## Measurement
-
-The [protocol fixture](../../examples/server/tests/rpc-transport-overhead.test.ts) uses real loopback
-Effect HTTP/WebSocket servers, ready clients, the public package factory, and a real QueryClient.
-Each row starts a fresh host, client, and cache, then runs concurrent unary queries with distinct
-integer payloads. JSON serialization, fixed request IDs, disabled RPC tracing, and disabled Query
-retries keep the request sizes comparable.

-At eight calls, WebSocket multiplexing reduces outbound bytes by about 75% while retaining eight
-envelopes and eight sends. At 32 calls the reduction is about 80%. Each query returns its individual
-value and creates a separate successful cache entry.
-
-Counts use encoded HTTP bodies, actual request lines/raw headers, WebSocket sends, and server TCP
-`bytesRead`. WebSocket totals include one upgrade and six masked-frame bytes per small request.
-Counts end after responses arrive and before disposal. Responses, TCP/IP headers, TLS, connection
-setup packets, and later keepalives are excluded. This measures bytes and requests, not latency,
-throughput, or CPU cost. HTTP connection counts reflect this cold concurrent HTTP/1.1 fetch pool;
-warm connections, HTTP/2, browsers, compression, larger payloads, and remote backends need their own
-measurement. Header sizes depend on the Node/fetch version and application headers.
-
-## Consequences
-
-Acquire the socket, build its protocol Layer into an application-owned client Scope with
-`Layer.buildWithScope`, and acquire the flat client with that Context and Scope. Keep the Scope
-alive while the utility tree uses the ready RPC client. Close the client Scope before its host;
-providing the socket protocol Layer only around acquisition closes its receive loop too early.
-
-For backend batching, share one `RequestResolver.make` instance in the server service, optionally
-set a collection delay with `RequestResolver.setDelay`, run the backend bulk operation, and complete
-each entry with its individual Exit. Handlers call `Effect.request(request, resolver)`. The installed
-recipe is `node_modules/effect/ai-docs/src/05_batching/10_request-resolver.ts`; collection belongs to
-the shared resolver instance and batch key. A collection delay adds latency.
-
-The package retains its lifecycle-neutral ready-client boundary and adds no automatic transport
-batching API.
+The utility tree adds no automatic transport batching. Backend request batching, transport
+aggregation, and Query publication address different costs and retain separate ownership.

 An encoder receives the normalized payload and must return a strict `JsonValue` synchronously. It
 must not reveal secrets. Return a stable public identifier, digest, or other safe semantic identity.
 
+Broad payload declarations such as `Schema.Unknown`, `Schema.Any`, and void-containing unions
+accept encoders too. Their default keys still require strict JSON: an accepted RPC input such as
+`undefined`, a bigint, or a class instance may require an encoder to supply JSON-safe identity.
+
 Define encoders as own enumerable properties keyed by literal payload-bearing RPC tags. TypeScript
 requires entries for unsafe payloads; the factory also rejects missing or unknown entries at runtime.

+## Stream creation and consumption
+
+For an accumulated streamed RPC or live RPC query, the runner executes
+`Stream.toAsyncIterableEffect` to create an iterable and capture its Effect `Context`. The runner
+returns a successful `Exit` before Query Core pulls values. Iterator pulls then use that captured
+Context while the query remains fetching. Keep its services and the ready client's Scope alive
+until consumption finishes.
+
+Apply transformations to the stream returned by the ready client, before it reaches the utility
+tree. Use `Stream.map` for value changes, `Stream.mapEffect` for service-dependent work,
+`Stream.tap` for per-emission instrumentation, and `Stream.ensuring` for completion or cancellation
+cleanup. For RPC, wrap the streaming call at the ready-client boundary; preserve its payload,
+request options, and declared success/error types. For HTTP, retain the native client's response
+mode contract when applying a stream transformation.
+
+A timer, span, finalizer, or retry schedule around the runner's creation Effect ends with iterable
+creation. It does not wrap the later pulls. Put stream-lifetime instrumentation and recovery on the
+stream itself. A retry in generated Query options reruns the query function and creates another
+iterable. Coordinate it with stream and transport schedules as described in
+[retry queries](/effect-api-query/guides/retry-queries/#set-defaults-deliberately).
+
+At shutdown, cancel active queries, await application-owned stream finalization, clear the cache,
+and then dispose the runtime or close the client Scope. `cancelQueries` restores Query's cache
+state; iterator cleanup can finish asynchronously, so wait for your resource's completion signal
+before disposal. Settle pending mutations separately because they have no query abort signal.
+
+The [packed runner fixture](https://github.com/ueberBrot/effect-api-query/blob/main/tests/packed-consumer/retry-runtime.mts)
+checks both stream views: creation finishes before the first transformed emission, pulls and
+finalizers retain the runner's provided Context, and cancellation finalizes the stream before
+client disposal.

+title: Retry Queries
+description: Choose bounded retries by inspecting typed Effect failures and native Query options.
+---
+
+Set an explicit retry policy for an idempotent read. The callbacks below allow two retries after
+an initial failure: at most three client executions. They retry a declared `RetryLater` or an HTTP
+transport failure, and stop for `NotFound`, `AuthenticationRequired`, Schema failures, defects,
+interruptions, and rejected runners.
+
+## Inspect the typed failure
+
+Share the declarations with your server and pass your application's ready client to
+`rpcReadOptions` or `httpReadOptions`. Both functions return native query options for `useQuery`
+or `queryClient.query`. Adapt the allowed tags and transport reasons to your read's contract.

+
+`Cause.findError` returns a `Result`; after `Result.isSuccess`, `success` retains the declared
+error union. It extracts the first typed failure. Check defects and interruptions first, and
+inspect all `cause.reasons` when several failures are meaningful to your policy. This example
+rejects every Cause with more than one reason, including a retryable failure combined with a defect,
+interruption, or another typed failure.
+
+The runtime guard also rejects a custom runner's original rejection. A runner rejection produces
+no failed Effect `Exit`, so it need not have the statically declared execution-error shape. Keep
+this guard in retry and retry-delay callbacks that can receive custom runner failures.
+
+An HTTP `TransportError` is safe to retry here because this operation is an idempotent read. Other
+`HttpClientError` reasons include encoding, decoding, and response failures. An RPC
+`RpcClientError` can contain HTTP, socket, worker, or protocol failures; the RPC policy above
+explicitly allows only its HTTP transport reason. Choose socket/worker reconnection policy in the
+application that owns that transport. Handle expired authentication by restoring the application
+session and invalidating affected queries, instead of repeatedly sending the same credentials.
+
+`retryDelay` receives the zero-based attempt index and the same typed error. It returns milliseconds,
+not an Effect or Promise. Query Core can evaluate it even for a terminal failure, so keep it pure.
+The example bounds server-provided delays and caps exponential backoff at 30 seconds.
+
+## Set defaults deliberately
+
+| Execution                                                      | Native retry default without application overrides |
+| -------------------------------------------------------------- | -------------------------------------------------- |
+| Browser query observer, such as `useQuery`                     | Three retries after the initial attempt            |
+| Server query observer                                          | Zero retries                                       |
+| Imperative `queryClient.query` and `queryClient.infiniteQuery` | Retries disabled                                   |
+| Mutation                                                       | Retries disabled                                   |
+
+Generated options preserve Query Core policy. QueryClient defaults, prefix defaults, and explicit
+builder options can change these defaults. Set `retry` explicitly when attempt counts matter;
+`retry: 2` also means at most three executions, while `retry: false` permits one.
+
+Apply the same decision in an infinite, accumulated-stream, or live builder only when restarting
+that operation is safe. A stream retry starts a new stream invocation; its retained data and refetch
+policy still govern cache publication. Mutation retries require an application idempotency contract.
+
+Choose one layer to own retries. If TanStack allows two retries and the underlying Effect or
+transport schedule also allows two retries per invocation, one query can make nine client attempts.
+Set `retry: false` in Query options when the ready client or runner owns a retry schedule. A retry
+around the runner's iterable-creation Effect does not retry subsequent stream consumption; see
+[client lifecycle](/effect-api-query/concepts/client-lifecycle/#stream-creation-and-consumption).
+
+## Handle preparation before execution
+
+Factory and option-builder configuration errors and key-generation errors are synchronous. Prepare
+options inside a `try` block when input or custom encoders may fail, then pass the successful options
+to Query Core. These errors occur before a query is registered and never enter execution retry.
+For an infinite query, the later page-input mapper executes during fetching; errors it throws reach
+TanStack unchanged and need an explicit non-retry decision. Mutations encode input inside the
+ready client's Effect, so their encoding failures use the execution Cause.
+
+Use [failure handling](/effect-api-query/guides/handle-failures/) for error-stage guards and
+[the error reference](/effect-api-query/reference/errors/) for stable metadata. The complete example
+is compiled against the installed package in
+[`tests/packed-consumer/docs-retry.ts`](https://github.com/ueberBrot/effect-api-query/blob/main/tests/packed-consumer/docs-retry.ts).

-Streaming RPC leaves expose `streamedKey`/`streamedOptions` for ordered history with `reset`,
-`append`, and `replace` refetch modes, and `liveKey`/`liveOptions` for the latest value. A live stream
-that completes without emitting a value raises `EffectRpcQueryEmptyStreamError`. Separate `streamed`
-and `live` key segments prevent collisions with other query shapes and mutations; generated prefixes
-support invalidation.
-
-Concrete accumulated-stream identity includes the normalized retention bound and refetch mode,
-so incompatible histories occupy separate cache entries. Omitted bounds mean unlimited retention;
-omitted refetch mode means reset. Exact key builders accept the same policy as options builders,
-and explicit defaults share identity with omitted defaults. Broad prefixes remain stable; persisted
-accumulated histories require a version change when adopting this identity.
-
-Live emissions normalize `undefined` to `null` under
-[ADR 0012](0012-normalize-undefined-query-success-to-null.md); accumulated elements remain
-unchanged. On an initial fetch, the first emission makes either view successful while the open
-stream remains fetching. Live completion preserves the latest normalized value.
-
-The ready RPC client remains the execution seam, including direct execution outside TanStack.
-Client construction and Effect middleware remain interception seams. Stream functions forward
-TanStack's abort signal and close the AsyncIterator on cancellation. A stream failure preserves its
-complete Cause in `EffectRpcQueryError`, including interruption-only and mixed interruption/defect
-Causes, while that signal is not aborted. Requested cancellation retains TanStack's native result
-and cache reversion, including superseded refetches and removal of the last observer.
-The application owns client/runtime resources, transport, middleware, Scope, QueryClient, and
-framework lifecycle. SSR dehydrates completed data normally; open streams require cancellation
-after the first successful snapshot. Mutations have no cancellation signal.
+Streams support two cached representations: ordered accumulated history and the latest live value.
+Keep these representations separate, and include retention and refetch policies in accumulated
+cache identity, because incompatible histories cannot safely share an entry. Broad key prefixes
+still support invalidation across views and policies.
+
+The adapter consumes caller-owned ready clients and follows TanStack cancellation while preserving
+complete Effect failures. Applications own transport, reconnection, and resource lifetime; server
+rendering must settle and stop open work before disposing those resources. Live values follow

-Publish one `effect-api-query` package at the workspace root. Export `createHttpApiQueryUtils` beside

-their distinct request and projection contracts.

+Expose HTTP and RPC utilities through one package, sharing private construction while preserving
+their distinct declaration and request contracts. HTTP utilities consume caller-owned ready clients
+and project only response shapes they can represent truthfully.
 
-HTTP mirrors literal group/endpoint names, including dots and top-level projection. The original buffered projection omitted an entire
-endpoint if any success alternative streams (including header-wrapped streams); omit empty groups.
-ADR 0024 permits an unambiguous single SSE success while retaining omission for mixed buffered/streamed successes and raw byte streams.
-The original decision also omitted any multipart payload alternative. ADR 0023 permits buffered
-multipart mutation builders while preserving omission for streaming multipart payloads. This prevents
-falsely buffered result types. Unsafe paths, collisions, and contradictory multipart metadata fail atomically.
-
-Accept decoded request parts and force decoded-only responses. Preserve query normalization and
-mutation data. Applications own ready-client resources and supply runners for encoding, decoding,
-and residual client services; key encoders supply only cache identity. HTTP-specific errors retain
-declaration metadata and untouched failed-Exit Causes, which may contain upstream request, response,
-or Schema issue values. Runner rejections pass through.
-
-Keys append `rpc` plus tag segments, or `http` plus API identifier and projected path, after the
-caller prefix. Operation and canonical query input follow. Factory `key()` includes this generated
-root, preventing cross-adapter collisions while retaining prefix invalidation. Applications own
-safe client-identity partitions and deliberate cross-adapter invalidation through the caller prefix.
+HTTP cache roots include the adapter and API identity, so HTTP endpoints and RPC tags cannot collide

 still infers the decoded user type.
 
+## Update with an ETag
+
+Use a metadata view to read decoded data, status, and raw response headers together. For this
+recipe, `users.get` returns a user and its server supplies an ETag. The `users.update` endpoint
+declares numeric `id` params, a string `if-match` header, a `{ name: string }` payload, and its
+precondition failure as a declared error.
+
+```ts
+const input = { params: { id: 1 } }
+const metadataOptions = http.users.get.metadataOptions({ input })
+const current = await queryClient.query(metadataOptions)
+const etag = current.headers['etag']
+if (etag === undefined) throw new Error('The server supplied no ETag')
+
+await queryClient.cancelQueries({ queryKey: http.users.get.key() })
+const update = new MutationObserver(
+  queryClient,
+  http.users.update.mutationOptions({
+    onSuccess: () => queryClient.invalidateQueries({ queryKey: http.users.get.key() }),
+  }),
+)
+await update.mutate({
+  params: input.params,
+  headers: { 'if-match': etag },
+  payload: { name: 'Ada' },
+})
+
+const refreshed = await queryClient.query(metadataOptions)
+```
+
+Send the ETag unchanged, including quotes. The server owns conditional-write enforcement; handle a
+declared precondition failure through the mutation's HTTP execution error. Invalidation uses the
+endpoint prefix so both ordinary data and metadata views refresh. Read the next ETag from the fresh
+metadata result before another write.
+
+`current.data` retains the endpoint's decoded success, including any declared decoded header
+wrapper. A top-level successful `undefined` becomes `null`. `current.status` is the response status;
+`current.headers` is a copied, frozen plain string record. The outer result is frozen, while decoded
+data keeps its declared representation. Raw headers can contain private values: choose which headers
+your application may persist or dehydrate.
+
+`metadataKey(input)` provides a typed key for cache reads and writes. Metadata options support
+selection, initial data, skipped input, native hashing defaults, and cancellation like ordinary
+queries. Metadata has its own cache identity and no mutation or infinite-query builders.

+## Retain SSE events
+
+An endpoint with one `HttpApiSchema.StreamSse` success exposes `streamedKey` and
+`streamedOptions`. For a `watch` endpoint whose query declares `channel: Schema.String`,
+retain its latest 100 decoded events:
+
+```ts
+const events = http.events.watch.streamedOptions({
+  input: { query: { channel: 'news' } },
+  maxChunks: 100,
+  refetchMode: 'reset',
+  sseOptions: { maxEventSize: 1024 * 1024 },
+})
+
+const observer = new QueryObserver(queryClient, events)
+const unsubscribe = observer.subscribe((result) => {
+  renderEvents(result.data ?? [])
+})
+```
+
+Import `QueryObserver` from `@tanstack/query-core`, or pass the options to your framework's
+query hook. Replace `renderEvents` with your application's rendering callback. The first event
+makes the query successful while it remains fetching. Unsubscribe and cancel the owning queries
+before disposing the ready client and runtime.
+
+The cache holds decoded events in order. Omit `maxChunks` for unlimited history; use a positive
+safe integer to bound retention. `reset` starts a fresh history on refetch, `append` extends the
+existing history, and `replace` keeps the previous history visible until the refetch completes.
+Empty completion succeeds with an empty or retained history according to the refetch mode.
+Accumulated arrays preserve decoded `undefined` elements. A declared `WithHeaders` success wraps
+each event with the response's decoded headers.
+
+Keep `sseOptions` beside `input`. Its `maxEventSize` limits pending SSE parser text in JavaScript
+string code units and defaults to 10 MiB. The same request with different effective decoder,
+retention, or refetch policies has a different cache key. To read that exact entry, pass the
+same policy to `streamedKey(input, policy)`; inputless endpoints accept policy alone.
+`key()` remains a prefix matching every policy. Input-bearing builders also support `skipToken`.
+
+Declared request headers, such as a resume cursor, remain inside `input.headers` and contribute
+to request identity. The ready client handles SSE decoding and failures; the adapter preserves
+complete Causes, including `Sse.Retry`. Your application owns reconnection and resume policy.
+Raw byte streams, mixed buffered/SSE successes, and SSE endpoints with multipart payloads are
+omitted. Consume unsupported streams directly through the ready client.

+wrappers surround each emitted body. Empty completion succeeds. Acquisition and consumption errors
+use `EffectHttpApiQueryError` with operation `streamed`, preserving declared event failures,
+`Sse.Retry`, `Sse.SseError`, HTTP and Schema errors, and additional client channels.
+The caller's runner supplies acquisition and consumption services and receives Query's abort signal.
+Cancellation closes the iterator and follows native Query cache reversion.
+
+`streamedKey(input, policy)` accepts the same decoder, retention, and refetch policy; inputless
+endpoints use `streamedKey(policy)`. Equivalent defaults have equal keys. Different effective
+policies occupy separate entries. Endpoint `key()` selects them all. Decoder controls are excluded
+from decoded request input and custom encoders. Declared resume headers remain request identity.

+title: Hydrate Unary Data
+description: Keep DTOs or rich Schema values consistent across JSON hydration and client refetch.
+---
+
+Choose the cache representation before connecting server rendering to TanStack Query. The server
+and browser must use the same contract, key prefix, and inputs. Each owns its Query Client, ready
+Effect client, and runtime. Cancel outstanding queries before disposing a runtime.
+
+These recipes cover unary profile reads through either factory. They keep only successful profile
+queries and omit mutations. Use an explicit strategy for other cached shapes, including infinite
+pages and stream snapshots.
+
+## Keep DTOs in both caches
+
+Use a JSON-safe success schema when components need plain data. The contract below keeps credits
+as decimal strings and binary data as base64 strings. Return this DTO from the server operation;
+the ready RPC or HTTP client produces the same DTO on the server and browser.
+
+Save the following as `docs-hydration-dto.ts`:
+
+```ts
+import { defaultShouldDehydrateQuery, dehydrate, hydrate } from '@tanstack/query-core'
+import type { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+import { createHttpApiQueryUtils, createRpcQueryUtils } from 'effect-api-query'
+import { HttpApi, HttpApiClient, HttpApiEndpoint, HttpApiGroup } from 'effect/http-api'
+import { Rpc, RpcClient, RpcGroup } from 'effect/rpc'
+
+export const ProfileDto = Schema.Struct({
+  name: Schema.String,
+  credits: Schema.String,
+  avatar: Schema.String.check(Schema.isBase64()),
+})
+
+export const dtoGroup = RpcGroup.make(Rpc.make('profile.read', { success: ProfileDto }))
+export const dtoApi = HttpApi.make('dto').add(
+  HttpApiGroup.make('profile').add(
+    HttpApiEndpoint.get('read', '/profile', { success: ProfileDto }),
+  ),
+)
+
+export function dtoRpcOptions<E>(
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof dtoGroup>, E>,
+) {
+  return createRpcQueryUtils<typeof dtoGroup, readonly ['dto', 'rpc'], E>(dtoGroup, {
+    client,
+    keyPrefix: ['dto', 'rpc'],
+  }).profile.read.queryOptions({ retry: false, staleTime: 60_000 })
+}
+
+export function dtoHttpOptions(client: HttpApiClient.ForApi<typeof dtoApi>) {
+  return createHttpApiQueryUtils(dtoApi, {
+    client,
+    keyPrefix: ['dto', 'http'],
+  }).profile.read.queryOptions({ retry: false, staleTime: 60_000 })
+}
+
+export const snapshotDto = (queryClient: QueryClient): string =>
+  JSON.stringify(
+    dehydrate(queryClient, {
+      shouldDehydrateMutation: () => false,
+      shouldDehydrateQuery: (query) =>
+        defaultShouldDehydrateQuery(query) && query.queryKey[0] === 'dto',
+    }),
+  )
+
+export const hydrateDto = (queryClient: QueryClient, json: string): void =>
+  hydrate(queryClient, JSON.parse(json))
+```
+
+Prefetch with `queryClient.query(dtoRpcOptions(rpcClient))` or the HTTP equivalent, then publish
+`snapshotDto(queryClient)` through your framework's JSON transport. Call `hydrateDto` on the
+browser's Query Client before its first query. The 60-second freshness window avoids an immediate
+duplicate read; subsequent invalidation and refetch still produce DTOs.
+
+If your domain layer uses classes, convert them to this DTO in the operation or ready-client
+adapter on both sides. TanStack's `select` changes an observer's result; it does not change cached
+query data.
+
+## Reconstruct Schema classes with paired codecs
+
+Keep decoded domain objects in the cache when components need methods or rich values. Encode at
+the snapshot boundary and decode during hydration. This `Profile` encodes bigint credits as a
+string and its `Uint8Array` avatar as base64. Decoding reconstructs the class and its `summary`
+method.
+
+Save the following as `docs-hydration-rich.ts`:
+
+```ts
+import { defaultShouldDehydrateQuery, dehydrate, hydrate } from '@tanstack/query-core'
+import type { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+import { createHttpApiQueryUtils, createRpcQueryUtils } from 'effect-api-query'
+import { HttpApi, HttpApiClient, HttpApiEndpoint, HttpApiGroup } from 'effect/http-api'
+import { Rpc, RpcClient, RpcGroup } from 'effect/rpc'
+
+export class Profile extends Schema.Class<Profile>('Profile')({
+  name: Schema.String,
+  credits: Schema.BigIntFromString,
+  avatar: Schema.Uint8ArrayFromBase64,
+}) {
+  summary(): string {
+    return `${this.name}: ${this.credits} credits`
+  }
+}
+
+export const profileGroup = RpcGroup.make(
+  Rpc.make('profile.read', { success: Profile, error: Schema.String }),
+)
+export const profileApi = HttpApi.make('rich').add(
+  HttpApiGroup.make('profile').add(
+    HttpApiEndpoint.get('read', '/profile', { success: Profile, error: Schema.String }),
+  ),
+)
+
+export function profileRpcOptions<E>(
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof profileGroup>, E>,
+) {
+  return createRpcQueryUtils<typeof profileGroup, readonly ['profile', 'rpc'], E>(profileGroup, {
+    client,
+    keyPrefix: ['profile', 'rpc'],
+  }).profile.read.queryOptions({ retry: false, staleTime: 60_000 })
+}
+
+export function profileHttpOptions(client: HttpApiClient.ForApi<typeof profileApi>) {
+  return createHttpApiQueryUtils(profileApi, {
+    client,
+    keyPrefix: ['profile', 'http'],
+  }).profile.read.queryOptions({ retry: false, staleTime: 60_000 })
+}
+
+export const snapshotProfile = (queryClient: QueryClient): string =>
+  JSON.stringify(
+    dehydrate(queryClient, {
+      shouldDehydrateMutation: () => false,
+      shouldDehydrateQuery: (query) =>
+        defaultShouldDehydrateQuery(query) && query.queryKey[0] === 'profile',
+      serializeData: Schema.encodeUnknownSync(Profile),
+    }),
+  )
+
+export const hydrateProfile = (queryClient: QueryClient, json: string): void =>
+  hydrate(queryClient, JSON.parse(json), {
+    defaultOptions: { deserializeData: Schema.decodeUnknownSync(Profile) },
+  })
+```
+
+Prefetch with `profileRpcOptions` or `profileHttpOptions`, publish `snapshotProfile`, then call
+`hydrateProfile` on the browser's Query Client. The hydrated value and a later browser refetch
+both have the `Profile` prototype, bigint credits, and byte array. Only the snapshot contains the
+encoded strings. The `'profile'` prefix in this recipe is reserved for unary `Profile` data;
+other query shapes need their own codec selection.
+
+`serializeData` and `deserializeData` are synchronous callbacks. The synchronous Schema functions
+must be able to finish without asynchronous work or required services. A codec failure throws;
+handle it through your rendering or hydration error path.
+
+`structuredClone` is not a paired JSON codec. It copies class properties without restoring the
+class prototype or methods. It preserves bigint and typed arrays in memory, but JSON still
+requires an encoding for those values. Cloning a server class alone also leaves hydration and a
+later class-valued refetch with different representations.
+
+## Finish effectful preparation before publishing or hydrating
+
+When a codec needs services or asynchronous work, prepare the entire snapshot outside TanStack's
+synchronous callbacks. This example adds a caller-owned preparation service to the same Profile
+codec. Its hooks can await application work before encoding or decoding.
+
+Save the following alongside `docs-hydration-rich.ts`:
+
+```ts
+import { defaultShouldDehydrateQuery, dehydrate, hydrate } from '@tanstack/query-core'
+import type { DehydratedState, QueryClient } from '@tanstack/query-core'
+import { Context, Effect, Schema } from 'effect'
+
+import { Profile } from './docs-hydration-rich.ts'
+
+export class HydrationPreparation extends Context.Service<
+  HydrationPreparation,
+  {
+    readonly beforeEncode: Effect.Effect<void>
+    readonly beforeDecode: Effect.Effect<void>
+  }
+>()('HydrationPreparation') {}
+
+const PreparedProfile = Profile.pipe(
+  Schema.middlewareEncoding<typeof Profile, HydrationPreparation>((encoding) =>
+    Effect.flatMap(HydrationPreparation, ({ beforeEncode }) =>
+      Effect.andThen(beforeEncode, encoding),
+    ),
+  ),
+  Schema.middlewareDecoding((decoding) =>
+    Effect.flatMap(HydrationPreparation, ({ beforeDecode }) =>
+      Effect.andThen(beforeDecode, decoding),
+    ),
+  ),
+)
+
+export const prepareProfileSnapshot = (queryClient: QueryClient) =>
+  Effect.gen(function* () {
+    const snapshot = dehydrate(queryClient, {
+      shouldDehydrateMutation: () => false,
+      shouldDehydrateQuery: (query) =>
+        defaultShouldDehydrateQuery(query) && query.queryKey[0] === 'profile',
+    })
+    const queries = yield* Effect.forEach(snapshot.queries, (query) =>
+      Schema.encodeUnknownEffect(PreparedProfile)(query.state.data).pipe(
+        Effect.map((data) => ({ ...query, state: { ...query.state, data } })),
+      ),
+    )
+    return JSON.stringify({ ...snapshot, queries })
+  })
+
+export const prepareProfileHydration = (queryClient: QueryClient, json: string) =>
+  Effect.gen(function* () {
+    const snapshot: DehydratedState = JSON.parse(json)
+    const queries = yield* Effect.forEach(snapshot.queries, (query) =>
+      Schema.decodeUnknownEffect(PreparedProfile)(query.state.data).pipe(
+        Effect.map((data) => ({ ...query, state: { ...query.state, data } })),
+      ),
+    )
+    yield* Effect.sync(() => hydrate(queryClient, { ...snapshot, queries }))
+  })
+```
+
+Provide `HydrationPreparation` through your application Context or ManagedRuntime. Await the
+result of `prepareProfileSnapshot` before publishing its JSON. On the browser, await
+`prepareProfileHydration` before allowing queries or components to read the hydrated cache. The
+latter decodes every entry before calling `hydrate`, so decoding failure leaves the destination
+cache untouched. Keep the preparation runtime alive until the Effect completes, and dispose it
+through the application's lifecycle.
+
+Neither preparation function puts an Effect or Promise into query data. The server cache keeps
+`Profile` values, the published snapshot contains encoded data, and the browser cache receives
+fully decoded `Profile` values. The Schema codec validates each profile; the surrounding snapshot
+must come from the matching application encoder. Query keys and metadata must also satisfy your
+JSON transport.
+
+## Omit failed queries by default
+
+Retain `defaultShouldDehydrateQuery` so failed queries stay out of the snapshot. The browser can
+refetch them with its own client and receive a fresh `EffectRpcQueryError` or
+`EffectHttpApiQueryError` and Cause. The recipes above preserve this policy even when selecting a
+profile prefix.
+
+If you deliberately transfer failed queries, define a safe application error representation.
+Encode and decode both `state.error` and `state.fetchFailureReason`; `serializeData` and
+`deserializeData` transform query data, not those error fields. Allowlist public failure tags and
+fields, omit private messages, defects, and transport details, and reconstruct the error behavior
+your UI requires. JSON serialization of an Error or Cause does not supply that policy. A safe
+error DTO will not automatically become either package error class or pass its type guard.
+
+For normal retry and error handling, keep failures local to each client and follow
+[Handle Failures](/effect-api-query/guides/handle-failures/) and
+[Retry Queries](/effect-api-query/guides/retry-queries/). For router ownership and cleanup, see
+[TanStack Start](/effect-api-query/guides/tanstack-start/).

+title: Query Defaults
+description: Reuse QueryClient policies with generated prefixes and typed call-site options.
+---
+
+Configure common freshness and retry policies on your application-owned `QueryClient`. Use
+generated prefixes to specialize those policies, then pass call-site options to the generated
+builders. The utility tree owns keys and execution functions; QueryClient owns hashing.
+
+Create the utility tree and QueryClient once for each cache owner. Keep the ready client's Scope
+alive while its queries run. Use a request-local QueryClient during SSR and dispose application
+resources through their owning runtime.
+
+## Register RPC policies from broad to specific
+
+This example disables retries globally, retries reads in the `users` branch twice, and keeps the
+`users.get` query view fresh for two minutes. The call-site `refreshUser` options request an
+immediate fetch without retries. `user` selects a name while the cache retains the full user.
+
+```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+import { createRpcQueryUtils } from 'effect-api-query'
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+
+export const usersRpc = RpcGroup.make(
+  Rpc.make('users.get', {
+    payload: { id: Schema.Int },
+    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+    error: Schema.TaggedStruct('RetryLater', {}),
+  }),
+)
+
+export const createApplicationQueries = <ClientError>(
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof usersRpc>, ClientError>,
+) => {
+  const rpc = createRpcQueryUtils<typeof usersRpc, readonly ['users-app'], ClientError>(usersRpc, {
+    client,
+    keyPrefix: ['users-app'],
+  })
+  const queryClient = new QueryClient({
+    defaultOptions: {
+      queries: { staleTime: 30_000, gcTime: 600_000, retry: false, retryDelay: 250 },
+      mutations: { retry: false },
+    },
+  })
+  queryClient.setQueryDefaults(rpc.key(), { staleTime: 60_000 })
+  queryClient.setQueryDefaults(rpc.users.key(), { retry: 2 })
+  queryClient.setQueryDefaults([...rpc.users.get.key(), 'query'], { staleTime: 120_000 })
+
+  const user = rpc.users.get.queryOptions({
+    input: { id: 1 },
+    select: (value) => value.name,
+  })
+  const refreshUser = rpc.users.get.queryOptions({
+    input: { id: 1 },
+    staleTime: 0,
+    retry: false,
+  })
+  return { queryClient, rpc, user, refreshUser }
+}
+```
+
+TanStack merges the QueryClient's global query defaults, every matching registered prefix in
+registration order, and the explicit options passed to the builder. Register broader prefixes
+first: TanStack does not sort them by specificity. Here the query inherits `gcTime: 600_000`,
+`retry: 2`, and `staleTime: 120_000`. `refreshUser` overrides freshness and retries for that call.
+
+`rpc.key()` covers the utility tree, `rpc.users.key()` covers its branch, and
+`rpc.users.get.key()` covers the leaf. Appending `'query'` targets that leaf's ordinary query view
+without applying its stale policy to an infinite or stream view. An operation prefix also covers
+all inputs of that view. Mutation policies use native `setMutationDefaults` separately.
+
+Omit an option to inherit its defaults. Use `staleTime: 0` to override an inherited freshness
+policy with immediate staleness. QueryClient imperative fetches and observers can have different
+built-in retry defaults, so set retry policy explicitly when attempts matter. `retry: 2` allows at
+most three executions. For typed decisions
+based on domain failures or transport errors, pass `retry` to the builder as shown in
+[Retry Queries](/effect-api-query/guides/retry-queries/).
+
+## Apply HTTP policies to separate views
+
+HTTP prefixes use the same native APIs. This example retries the `users` group once, applies a
+five-second stale time only to the metadata view, and hashes every view through QueryClient's
+root-prefix policy. The ordinary query retains the global thirty-second stale time.
+
+```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+import { createHttpApiQueryUtils } from 'effect-api-query'
+import { HttpApi, HttpApiEndpoint, HttpApiGroup, HttpApiSchema } from 'effect/http-api'
+import type { HttpApiClient } from 'effect/http-api'
+
+export const usersApi = HttpApi.make('users').add(
+  HttpApiGroup.make('users').add(
+    HttpApiEndpoint.get('get', '/users/:id', {
+      params: { id: Schema.Int },
+      success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+      error: Schema.TaggedStruct('RetryLater', {}).pipe(HttpApiSchema.status(503)),
+    }),
+  ),
+)
+
+export const createHttpApplicationQueries = (client: HttpApiClient.ForApi<typeof usersApi>) => {
+  const http = createHttpApiQueryUtils(usersApi, { client, keyPrefix: ['users-app'] })
+  const queryClient = new QueryClient({
+    defaultOptions: {
+      queries: { staleTime: 30_000, retry: false, retryDelay: 250 },
+    },
+  })
+  queryClient.setQueryDefaults(http.key(), {
+    queryKeyHashFn: (key) => `users:${JSON.stringify(key)}`,
+  })
+  queryClient.setQueryDefaults(http.users.key(), { retry: 1 })
+  queryClient.setQueryDefaults([...http.users.get.key(), 'metadata'], { staleTime: 5_000 })
+
+  const input = { params: { id: 1 } }
+  const user = http.users.get.queryOptions({ input })
+  const metadata = http.users.get.metadataOptions({ input })
+  return { queryClient, http, user, metadata }
+}
+```
+
+The ordinary and metadata views have separate keys. Configure global or prefix `queryKeyHashFn`
+on QueryClient before using the cache, and keep it stable for the cache owner's lifetime. Generated
+options retain their own query function even if a prefix registers another one. Builders reject
+per-call `queryHash` and `queryKeyHashFn` because native key-only reads and writes must resolve the
+same entry.
+
+Use the generated exact `queryKey(input)` or `metadataKey(input)` with native `getQueryData` and
+`setQueryData`. Their data tags preserve the unselected query data type: selecting a name changes
+the observer result, while a native write still supplies the complete user. A fresh native write
+is visible to observers and subsequent imperative reads without another client execution.
+
+Fetched metadata snapshots inherit QueryClient's global or prefix `structuralSharing` policy.
+Selected metadata results and later manual writes use an explicit per-call `metadataOptions`
+policy, or standard deep sharing if omitted. Initial, hydrated, manually written, and selected
+objects remain application-owned. Decoded data is not deep-frozen. See
+[Buffered metadata](/effect-api-query/reference/http-factory/#buffered-metadata) for that boundary.
+
+## Keep defaults in native Query APIs
+
+A per-operation defaults map would replace the repeated `setQueryDefaults(prefix, policy)` calls
+with a map and a registration loop. These recipes need only prefix selection and native policy
+merging, both already provided by TanStack. The map would add configuration without useful
+behavior, so the package provides no defaults helper. Keep shared policies on QueryClient and
+operation-specific selection, input, and typed error callbacks on the generated builders.

+title: Cache Filters
+description: Compose native filters for operations, encoded partial inputs, and exact cache entries.
+---
+
+Pass generated prefixes or concrete keys to TanStack's native filters. Choose the scope before
+adding `type`, `stale`, `fetchStatus`, or `predicate` conditions:
+
+| Scope                 | Key                                                    | Matches                                                                |
+| --------------------- | ------------------------------------------------------ | ---------------------------------------------------------------------- |
+| Root                  | `rpc.key()` or `http.key()`                            | All cached query views in that utility tree                            |
+| Branch                | `rpc.users.key()`                                      | Every descendant leaf and query view                                   |
+| Leaf                  | `rpc.users.get.key()`                                  | Ordinary and infinite queries; HTTP leaves also include metadata views |
+| Operation             | `[...rpc.users.get.key(), 'query']`                    | Ordinary queries for that leaf                                         |
+| Encoded partial input | Operation prefix followed by an encoded partial object | Entries containing those encoded fields                                |
+| Exact entry           | Generated concrete key with `exact: true`              | One complete cache identity, including its stream policy               |
+
+A streaming leaf prefix includes accumulated and live views. Append `streamed` or `live` to select
+one representation. HTTP buffered metadata uses `metadata`; pagination uses `infinite`.
+Mutation keys belong to TanStack's separate mutation cache, and query invalidation does not affect
+pending mutations.
+
+## Filter RPC queries
+
+This recipe accepts an application-owned ready client. Its `forId` filter matches every locale for
+one user, while `exact` retains the generated DataTag for one complete payload:
+
+```ts
+import { Effect, Schema } from 'effect'
+import { createRpcQueryUtils } from 'effect-api-query'
+import { Rpc, RpcClient, RpcGroup } from 'effect/rpc'
+
+const User = Schema.Struct({ id: Schema.Finite, name: Schema.String })
+const payload = {
+  id: Schema.FiniteFromString,
+  locale: Schema.String.pipe(Schema.withConstructorDefault(Effect.succeed('en'))),
+}
+export const usersRpc = RpcGroup.make(
+  Rpc.make('users.get', { payload, success: User }),
+  Rpc.make('users.watch', { payload, success: User, stream: true }),
+  Rpc.make('users.list', { success: Schema.Array(User) }),
+  Rpc.make('health.ping', { success: Schema.String }),
+)
+
+export const userCacheFilters = (
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof usersRpc>>,
+) => {
+  const rpc = createRpcQueryUtils(usersRpc, { client, keyPrefix: ['users-app'] })
+  const queryPrefix = [...rpc.users.get.key(), 'query'] as const
+  const historyPrefix = [...rpc.users.watch.key(), 'streamed'] as const
+
+  return {
+    rpc,
+    root: { queryKey: rpc.key() },
+    branch: { queryKey: rpc.users.key() },
+    leaf: { queryKey: rpc.users.get.key() },
+    query: { queryKey: queryPrefix },
+    forId: (id: number) => ({ queryKey: [...queryPrefix, { id: String(id) }] as const }),
+    history: { queryKey: historyPrefix },
+    historyForId: (id: number) => ({
+      queryKey: [...historyPrefix, { id: String(id) }] as const,
+    }),
+    exact: (id: number, locale = 'en') => ({
+      queryKey: rpc.users.get.queryKey({ id, locale }),
+      exact: true as const,
+    }),
+  }
+}
+```
+
+Create the filters with `userCacheFilters(client)`, then pass a filter to
+`queryClient.invalidateQueries(filters.forId(1))`. Combine native conditions by spreading the filter,
+for example `{ ...filters.forId(1), type: 'inactive', stale: false }`. Use
+`queryClient.getQueryData(filters.exact(1).queryKey)` for a typed user read.
+
+Partial matching compares stored canonical key payloads. Here `FiniteFromString` encodes the numeric
+constructor input `1` as `"1"`, so the partial object must use `id: "1"`. A raw `id: 1` matches no
+entry. An omitted field places no constraint; specifying `locale: "en"` selects that locale.
+Nested objects match recursively, arrays match by position, and scalar values must match exactly.
+A scalar string filter does not perform substring matching.
+
+Use the concrete builder for complete constructor input. Calling `queryKey({ id: 1 })` materializes
+the default `locale: "en"`; its key therefore cannot express every locale for user 1. Passing only
+`{ locale: "en" }` rejects the missing required `id`. Do not cast partial constructor input into a
+key builder or run it through the full payload constructor to derive a broad filter.
+
+`historyForId(1)` stops before the stream-policy suffix and matches every retention bound and
+refetch mode for that encoded user. For one history, use
+`rpc.users.watch.streamedKey({ id: 1 }, { maxChunks: 2, refetchMode: 'append' })` with `exact: true`.
+The omitted policy and explicit unlimited/reset policy share the same normalized identity. Keep the
+remaining concrete suffix opaque; root, branch, leaf, and operation filters survive policy changes.
+
+## Filter HTTP queries
+
+HTTP partial objects retain their labelled request containers. This recipe selects a path parameter
+or normalized header without constraining the query or payload:
+
+```ts
+import { Schema } from 'effect'
+import { createHttpApiQueryUtils } from 'effect-api-query'
+import {
+  HttpApi,
+  HttpApiClient,
+  HttpApiEndpoint,
+  HttpApiGroup,
+  HttpApiSchema,
+} from 'effect/http-api'
+
+export const usersApi = HttpApi.make('users-api').add(
+  HttpApiGroup.make('users').add(
+    HttpApiEndpoint.post('get', '/users/:id', {
+      params: { id: Schema.FiniteFromString },
+      query: { id: Schema.FiniteFromString, filter: Schema.optional(Schema.String) },
+      headers: Schema.Record(Schema.String, Schema.optional(Schema.String)),
+      payload: Schema.Struct({ id: Schema.FiniteFromString }),
+      success: Schema.String,
+    }),
+    HttpApiEndpoint.get('watch', '/users/events', {
+      query: { id: Schema.FiniteFromString },
+      success: HttpApiSchema.StreamSse({ data: Schema.String }),
+    }),
+  ),
+  HttpApiGroup.make('system', { topLevel: true }).add(
+    HttpApiEndpoint.get('ping', '/health', { success: Schema.String }),
+  ),
+)
+
+export const httpCacheFilters = (client: HttpApiClient.ForApi<typeof usersApi>) => {
+  const http = createHttpApiQueryUtils(usersApi, { client, keyPrefix: ['users-app'] })
+  const queryPrefix = [...http.users.get.key(), 'query'] as const
+
+  return {
+    http,
+    root: { queryKey: http.key() },
+    branch: { queryKey: http.users.key() },
+    leaf: { queryKey: http.users.get.key() },
+    query: { queryKey: queryPrefix },
+    forId: (id: number) => ({
+      queryKey: [...queryPrefix, { params: { id: String(id) } }] as const,
+    }),
+    forLocale: (locale: string) => ({
+      queryKey: [...queryPrefix, { headers: { 'x-locale': locale } }] as const,
+    }),
+    historyForId: (id: number) => ({
+      queryKey: [...http.users.watch.key(), 'streamed', { query: { id: String(id) } }] as const,
+    }),
+    exact: (input: Parameters<typeof http.users.get.queryKey>[0]) => ({
+      queryKey: http.users.get.queryKey(input),
+      exact: true as const,
+    }),
+  }
+}
+```
+
+Pass `httpCacheFilters(client).forId(1)` to `invalidateQueries` to refresh ordinary queries for path
+parameter 1. Use the leaf filter to include infinite and metadata views too. `historyForId(1)`
+selects every accumulated retention policy for the SSE request with query parameter 1.
+
+Default HTTP keys Schema-encode each request part, omit encoded `undefined` object members, and
+lowercase header names. In this contract, `params: { id: "1" }` is a meaningful partial object;
+`params: { id: 1 }` is not. Filter `headers: { 'x-locale': 'en' }` even when the decoded request uses
+`'X-Locale'`. Preserve `params`, `query`, `headers`, and `payload`: `{ query: { id: "7" } }` and
+`{ payload: { id: "7" } }` select different requests. An unlabelled `{ id: "7" }` matches neither.
+HTTP request input does not use RPC payload construction.
+
+## Bound partial filters to the encoded shape
+
+A custom encoder replaces the default encoded shape. If it returns
+`{ entity: { identifier: "1" }, language: "en" }`, filter by
+`{ entity: { identifier: "1" } }`, using the same operation prefix. `{ id: "1" }` no longer matches.
+If it returns the scalar `"1:en"`, native partial object matching cannot recover the original `id` or
+locale. HTTP custom encoders also replace request labels and header normalization.
+
+Applications that need partial matching can define an explicit JSON object projection in their
+encoder and build filters against that projection. Preserve every safe value that distinguishes
+results. Treat projection changes as cache-identity changes, including persisted-cache version
+busters. For opaque or noninvertible projections, use generated broad prefixes or a generated exact
+key. A custom predicate can inspect only the information retained in the key or other
+application-owned query metadata; it cannot reconstruct omitted input.
+
+The package keeps filter composition native. A generic partial-constructor helper cannot promise
+meaningful matching across defaults, Schema transformations, and arbitrary encoder output. The
+small operation-prefix expressions already compose with every native condition, so an additional
+public helper would add no proven capability. This preserves the
+[filter-composition decision](https://github.com/ueberBrot/effect-api-query/blob/main/docs/adr/0008-use-flat-prefix-matchable-key-tuples.md).
+
+Concrete builders retain DataTags for typed `getQueryData` and `setQueryData`. Manually composed
+prefixes and partial keys carry no query-data tag, and native `getQueriesData` does not infer a
+homogeneous result from its filter. Keep broad reads as `unknown` until the application establishes
+the matched representation; an explicit generic or cast does not validate cached values.
+
+The [packed filter consumer](https://github.com/ueberBrot/effect-api-query/blob/main/tests/packed-consumer/filter-runtime.mts)
+executes these recipes with real QueryClient caches and official Effect test clients. Its
+[compiled contract](https://github.com/ueberBrot/effect-api-query/blob/main/tests/packed-consumer/filter-contract.ts)
+checks exact DataTags and the limits of partial-key inference.

+title: Stream Snapshots
+description: Capture an accumulated or live stream for server rendering and hydrate an independent browser cache.
+---
+
+Use `fetchStreamSnapshot` when server rendering needs data from an open RPC or HTTP SSE query.
+It waits for the first new cache publication or normal completion, cancels the exact query, and
+awaits its local iterator cleanup. Ordinary `queryClient.query` waits for an open stream to finish.
+
+## Capture data before dehydration
+
+Pass generated accumulated or live options to the helper. Keep the ready client and runner alive
+until the returned Promise settles. This example captures separate history and latest-value views:
+
+```ts
+import type { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+import { createRpcQueryUtils, fetchStreamSnapshot } from 'effect-api-query'
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+
+export const updates = RpcGroup.make(
+  Rpc.make('updates.watch', {
+    payload: { channel: Schema.String },
+    success: Schema.String,
+    stream: true,
+  }),
+)
+
+export async function captureUpdates<E>(
+  queryClient: QueryClient,
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof updates>, E>,
+  signal: AbortSignal,
+) {
+  const rpc = createRpcQueryUtils<typeof updates, readonly ['updates'], E>(updates, {
+    client,
+    keyPrefix: ['updates'],
+  })
+  const input = { channel: 'announcements' }
+  const history = await fetchStreamSnapshot(
+    queryClient,
+    rpc.updates.watch.streamedOptions({
+      input,
+      retry: false,
+      maxChunks: 20,
+    }),
+    { signal, timeoutMs: 5_000 },
+  )
+  const latest = await fetchStreamSnapshot(
+    queryClient,
+    rpc.updates.watch.liveOptions({
+      input,
+      retry: false,
+    }),
+    { signal, timeoutMs: 5_000 },
+  )
+  return { history, latest }
+}
+```
+
+Call `captureUpdates` with a request-local QueryClient, ready client, and request abort signal.
+Then dehydrate successful data with TanStack's normal policy and your application's serializer.
+For HTTP SSE, pass `streamedOptions` or `liveOptions` from the HTTP utility tree in the same way.
+Use [Hydrate Unary Data](/effect-api-query/guides/hydrate-unary-data/) for paired Schema codecs,
+including accumulated arrays and live values.
+
+The default `fresh` mode starts a new attempt even when cached or initial data has a future
+timestamp. Old data cannot settle that attempt. Native stream policies still apply: `append`
+includes existing history, and `replace` on a previously fetched query publishes only at completion.
+An open replacement stream therefore needs to complete or reach the timeout.
+
+Choose `mode: 'cached'` to return an existing successful value without starting or cancelling work.
+The helper applies native `select`, including QueryClient defaults. When no successful cache entry
+exists, cached mode starts a fresh capture.
+
+## Keep capture ownership exclusive
+
+Use a request-local QueryClient and reserve the exact key throughout capture. A fresh capture
+rejects a key that is fetching, paused, or observed. Other keys keep running. Avoid same-key writes,
+observers, or concurrent fetches until capture settles: an external `setQueryData` publication can
+otherwise be mistaken for the stream's first value. Configure hashing through QueryClient global
+or prefix defaults; per-call `queryHash` and `queryKeyHashFn` are rejected.
+
+The helper removes its cache listener, request abort listener, and timeout on every outcome. It
+waits for the supplied query function to finish local cleanup before returning or rejecting.
+Dispose the server's ready client, Scope, or runtime after that settlement. This does not await a
+remote server's cancellation acknowledgement. A finalizer that never finishes also prevents
+settlement; `timeoutMs` limits the wait for data, not the duration of finalization.
+
+## Hydrate and reconnect in the browser
+
+Give the browser its own QueryClient, ready client, runner, and Scope. Hydrate the server snapshot
+using the same safe key prefix and input, then observe the generated stream options with your
+usual refetch policy. A new browser fetch reconnects with browser-owned resources; disposing the
+server's resources cannot dispose those resources.
+
+The [TanStack Start example](/effect-api-query/guides/tanstack-start/) captures server snapshots
+and reconnects accumulated and live views after hydration. The
+[helper reference](/effect-api-query/reference/public-exports/#fetchstreamsnapshot) defines timeout,
+abort, failure, empty-stream, and completion outcomes.

-## Capture an RPC stream snapshot
+## Capture a stream snapshot
 
-Completed stream data uses TanStack's normal dehydration contract. An open RPC stream remains
-in `fetchStatus: 'fetching'`. To render its first successful value, start the generated query,
-wait for a successful cache snapshot, then cancel the query before dehydration completes.
-Cancellation closes the iterator and releases its Effect resources. The browser hydrates the

+title: Switch Cache Owners
+description: Isolate private queries, pending writes, and persisted directory data when an owner changes.
+---
+
+Include every safe identity that changes a result in the key prefix: tenant, user, session
+generation, and permission generation. Use application identifiers and numeric generations;
+bearer credentials never belong in keys or storage names. A permission change needs a new generation
+even when the user and tenant stay the same. These values partition caches; the server still
+owns authorization.
+
+## Capture one owner
+
+Copy [the existing Vite application's owner cache](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/lib/owner-cache.ts)
+into `owner-cache.ts`. The following focused recipe accepts already acquired clients and captures
+one QueryClient, identity, and set of generated utilities. Keep their owning Scopes and runtimes
+alive until this owner's work finishes.
+
+```ts

+
+import { makeOwnerCache, ownerKeyPrefix } from './owner-cache.ts'

+
+export const DirectoryUser = Schema.Struct({
+  id: Schema.Int,
+  name: Schema.String,
+  locale: Schema.String,
+})
+
+export const ownerGroup = RpcGroup.make(
+  Rpc.make('users.list', { success: Schema.Array(DirectoryUser) }),
+  Rpc.make('users.get', { payload: { id: Schema.Int }, success: DirectoryUser }),
+  Rpc.make('users.create', {
+    payload: { name: Schema.String },
+    success: DirectoryUser,
+  }),
+  Rpc.make('users.watch', { success: Schema.String, stream: true }),
+)
+
+export const ownerApi = HttpApi.make('owner-directory').add(

+    HttpApiEndpoint.post('create', '/users', {
+      payload: { name: Schema.String },

+  ),
+)

+  })

+    keyPrefix,
+    runPromiseExit,
+  })
+  const http = createHttpApiQueryUtils(ownerApi, { client: httpClient, keyPrefix, runPromiseExit })
+  const owner = makeOwnerCache({
+    identity,
+    queryClient,
+    directoryKeys: { rpc: rpc.users.list.queryKey(), http: http.users.list.queryKey() },
+    storage,
+  })
+  owner.restoreDirectory()
+  const invalidateUsers = async () => {
+    if (!owner.isActive()) {
+      return
+    }
+    await Promise.all([
+      queryClient.invalidateQueries({ queryKey: rpc.users.key() }),
+      queryClient.invalidateQueries({ queryKey: http.users.key() }),
+    ])
+  }
+  const createUser = owner.trackMutationOptions(
+    rpc.users.create.mutationOptions({
+      onSuccess: async (user) => {
+        if (!owner.isActive()) {
+          return
+        }
+        queryClient.setQueryData(rpc.users.get.queryKey({ id: user.id }), user)
+        await invalidateUsers()
+      },
+      onSettled: invalidateUsers,
+    }),
+  )
+  return { owner, queryClient, rpc, http, createUser, invalidateUsers }
+}
+```
+
+The success callback captures its original owner. It checks that owner before seeding a concrete
+query, and settlement invalidation uses the same guard. An old callback never looks up a current
+application variable to choose where to write. Apply the guard to rollback, optimistic writes,
+manual cache updates, and any later work after an `await` too.
+
+## Replace the consumer boundary
+
+The [existing Vite application](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/lib/application.ts)
+provides `switchViteReactApplication(previous, options)`. Capture `previous`, unmount its consumer
+tree, then await the handoff and render the returned application. The helper retires the old owner
+before constructing the new clients, QueryClient, and utilities. A failed acquisition leaves the
+old owner inactive; handle that failure in the surrounding application.
+
+[ViteReactExample](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/app.tsx)
+keys its QueryClientProvider by the immutable owner identity. A changed identity or generation
+therefore remounts query and mutation consumers. Passing a new QueryClient through an existing
+provider alone does not replace the QueryClient captured by existing hooks. Reassigning options
+on a pending MutationObserver can also replace its callbacks. Capture originating ownership in
+mutation context and replace observers at the handoff; arbitrary observer reassignment is outside
+this recipe.
+
+Retirement immediately marks the captured owner inactive and removes its persisted snapshot.
+It cancels old queries and streams, clears both native caches, and waits for accepted mutation
+requests to settle. The application then releases its HTTP runtime and RPC client Scope. Complete
+local stream cleanup before acquiring the next owner. Native `cancelQueries()` settlement alone
+is not a finalizer acknowledgement, and local disposal is not a remote server acknowledgement.
+
+The example attempts mutations immediately with `networkMode: 'always'` and `retry: false`.
+It does not keep an offline mutation queue. `runMutation` tracks requests that have started;
+new requests are rejected after retirement. Requests already accepted may complete on the server,
+and switching owners does not undo them. Their `onSuccess` or `onSettled` callbacks may finish
+after the request drain, so the ownership guard remains necessary. A hanging request or local
+finalizer can delay the handoff; this policy supplies no completion deadline. Do not introduce
+serialized mutation queues without an explicit ownership and shutdown policy.
+
+## Restore a directory snapshot
+
+Pass application-approved Storage to the Vite application through `directoryStorage`. The browser
+entry uses sessionStorage. `persistDirectory()` writes only the RPC and HTTP `users.list` DTOs:
+arrays of `{ id: number, name: string, locale: string }`. It stores no mutations, errors, arbitrary
+query keys, classes, streams, infinite pages, or bearer credentials. A pending mutation removes
+the stored snapshot so an optimistic directory cannot be reused after reload.
+
+Storage names include the full safe owner tuple. Each envelope repeats that identity and includes
+`schemaVersion: 1` and `keyVersion: 1`. Restoration validates the complete envelope and all DTO
+entries, checks both busters and all owner fields, then writes through keys derived by the current
+utilities. Foreign or incompatible data is deleted before any cache write. A different owner's
+storage slot is never read. Bump the schema buster when DTO meaning changes and the key buster
+when the persisted view's key contract changes.
+
+Restored DTOs are plain data with `dataUpdatedAt: 0`, so ordinary queries refetch them. Class
+constructors and methods are not restored by this recipe; use a paired codec from
+[Hydrate Unary Data](/effect-api-query/guides/hydrate-unary-data/) when the domain requires them.
+
+Default `dispose()` and owner switches erase persistence. The browser's pagehide cleanup explicitly
+uses `dispose({ discardPersistence: false })` to snapshot a settled directory for a reload while
+retiring the old in-memory owner and releasing its clients. Old-owner persistence calls become
+no-ops. Storage failures propagate while query, cache, and client cleanup still run.

+title: Optimistic User Writes
+description: Seed typed entries, roll back individual writes, and reconcile overlapping mutations.
+---
+
+Use generated concrete keys to update the reads affected by a mutation. Keep the write workflow
+in the application, where the relationship between a domain operation and its reads is known.
+
+The Vite React example applies this workflow to its existing user forms and directory. Copy
+[the user-write module](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/lib/user-writes.ts)
+and compose it with your application's ready clients and QueryClient, as in
+[the application](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/lib/application.ts).
+Its RPC and HTTP forms use the same application workflow and maintain distinct cache entries.
+
+## Seed the mutation response
+
+After creating a user, the example replaces that mutation's temporary entry in each cached
+list with the returned `User`. It also seeds these concrete detail keys:
+
+- `rpcQuery.users.get.queryKey({ id: user.id, locale: user.locale })`
+- `httpQuery.users.get.queryKey({ params: { id: user.id }, query: { locale: user.locale } })`
+
+The locale is part of the read input. A response with locale `fr` does not satisfy a detail query
+whose constructor supplies the default locale `en`.
+
+Use the generated DataTag keys directly with `getQueryData` and `setQueryData`. QueryClient owns
+the hash function, including global and prefix defaults; the generated keys also serve native
+cancellation and invalidation. Do not hash the keys independently.
+
+## Apply and reconcile an optimistic write
+
+The example's mutation options perform these actions:
+
+1. Capture the original owner and reserve the write before awaiting anything.
+2. Cancel the related RPC and HTTP reads through their generated user branch prefixes.
+3. Snapshot the affected list and infinite entries. For deletion, keep the removed entity and its
+   positions. For creation, allocate a temporary negative ID that belongs to this write.
+4. Publish the optimistic change. Pending users cannot be deleted through the forms.
+5. Replace a created user's temporary ID with the response, or roll back the failed write.
+6. Invalidate both user branches when the final overlapping write settles.
+
+Mutation responses remain ordinary Effect success values. An optimistic rollback restores the
+application's cache; it cannot undo work the server has accepted.
+
+## Preserve infinite pages
+
+The example updates its existing four-user page views through their generated infinite keys.
+It retains every page, `pageParams`, and unrelated user. A failed deletion restores only the
+removed user at its former page position, preserving users created in the meantime.
+
+Creation adjusts the total count on cached pages. It appends the new user to the last loaded page
+only when that page has no next cursor. A partial directory waits for reconciliation to determine
+where the user belongs. Each reconstructed page retains the `UserPage` representation.
+
+Offset pagination can change after deletion or insertion. Preserving the current page structure
+keeps the optimistic view usable until settlement invalidation refreshes the server's page
+boundaries and cursors. Add concrete keys for any other page sizes or filters your application
+uses; this example registers only its existing page size and initial cursor.
+
+## Keep overlapping writes safe
+
+A full snapshot rollback can erase a later successful write. The example instead removes a
+failed creation's own temporary user, or restores one deleted user without replacing the list.
+Overlapping deletions of the same user share the first snapshot: one successful deletion prevents
+an older failure from restoring it, while all failed deletions restore the original entity once.
+
+Each new write cancels an earlier reconciliation fetch before publishing its optimistic change.
+Only the final pending write triggers settlement refetches, so an older settlement does not
+refresh over a newer optimistic result. Success callbacks also cancel reads before seeding the
+returned value. Native cancellation prevents a cancelled query from publishing a late result.
+
+All writes to these views must participate in the same application workflow. Background domain
+refreshes, manual cache replacement, and server-side write conflicts need their own coordination.
+The example does not infer server ordering or define a general conflict-resolution policy.
+
+## Retain the original owner
+
+The `onMutate` result carries the original owner's commit, rollback, and settlement actions.
+Callbacks invoke those actions and check that owner is active. A late response can neither refill
+a cleared retired cache nor seed or invalidate a replacement client's entries.
+
+Native MutationObserver option updates can replace callbacks on a pending mutation. Carrying the
+transaction in `onMutate` prevents a later callback closure from redirecting an already-started
+write. Remount mutation consumers when replacing an application owner: an options change while
+`onMutate` awaits cancellation can otherwise replace the mutation function before it starts.
+
+Track mutation-function completion before releasing the application's ready clients. These
+writes use `networkMode: 'always'` and `retry: false`, so a retired owner does not retain paused
+mutation work. They do not use a native mutation scope queue. Mutations have no query abort signal;
+retirement and cache clearing do not cancel an accepted server write.
+
+The existing
+[Vite tests](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/tests/user-writes.test.ts)
+and
+[copied packed consumer](https://github.com/ueberBrot/effect-api-query/blob/main/tests/packed-consumer/optimistic-runtime.mts)
+exercise response seeding, page reconciliation, older failures, late callbacks, stale refetches,
+native hashes, and retired owners.

+title: Hydrate Query Views
+description: Preserve infinite pages, stream histories, live values, and HTTP metadata across JSON hydration and refetch.
+---
+
+Choose one codec for each cached representation. A success Schema describes a decoded result;
+infinite pages also contain page parameters, and HTTP metadata adds an envelope. Keep decoded
+values in the Query Client and encode only the snapshot sent to the browser.
+
+This recipe extends the [paired Profile codec](/effect-api-query/guides/hydrate-unary-data/).
+The server and browser own independent ready clients, runtimes, Scopes, and Query Clients.
+Use the same contract, input, key prefix, and Query Client hashing defaults on both sides.
+
+## Give each view an explicit codec
+
+Reserve a key prefix of `['hydration-views', codecId, ...applicationIdentity]` when creating each
+utility tree. The generated key suffix retains its usual operation, input, and view policies.
+Choose `codecId` from the map below; add your owner identity after it when data depends on an owner.
+
+| Codec ID          | Cached representation                                         |
+| ----------------- | ------------------------------------------------------------- |
+| `history`         | Ordered `Profile`, `undefined`, and `null` elements           |
+| `infinite`        | Profile pages and explicitly encoded `Cursor` page parameters |
+| `live`            | Latest Profile or normalized `null`                           |
+| `buffered`        | Decoded HTTP header wrapper with either declared success      |
+| `metadata`        | Buffered wrapper, response status, and raw string headers     |
+| `wrapped-history` | Ordered decoded HTTP header wrappers                          |
+| `wrapped-live`    | Latest decoded HTTP header wrapper                            |

+
+The map belongs to the application: it knows which page-parameter policy, declared success union,
+and public metadata each view needs. TanStack's `serializeData` callback receives data alone.
+Use the query key in an explicit preparation stage to choose among these codecs.
+
+## Preserve page parameters and stream values
+
+Use a `Cursor` as `infiniteOptions.initialPageParam`. Return the next Cursor from
+`getNextPageParam`, and let the deterministic `input` mapper convert its offset into your
+contract's request input. `ProfilePages` encodes both arrays: its page parameters become decimal
+strings at the JSON boundary and regain their Cursor prototype and methods during hydration.
+A result Schema alone cannot choose this page-parameter representation.
+
+Accumulated history preserves decoded `undefined` elements. Ordinary JSON would turn an
+undefined array element into `null`, so `UndefinedElement` encodes it as a distinct tagged value.
+A real `null` remains `null`. Live queries already normalize an entirely undefined emission to
+`null`; their codec retains that value.
+
+For an HTTP header wrapper, normalization applies to the whole emitted value. A wrapper whose
+`body` is undefined remains a wrapper with an undefined body. `WrappedElement` preserves that
+body with the same tagged encoding and reconstructs the wrapper with
+`HttpApiSchema.withHeaders`. `WithHeaders` is an HTTP declaration; use explicit body/header
+codecs at the JSON boundary so rich body values and decoded numeric headers regain their types.
+
+`BufferedProfile` includes both declared HTTP successes. Adapt that union to your endpoint and
+its status declarations. `ProfileMetadata` preserves decoded data, numeric status, and raw
+string headers. Hydrated envelopes belong to the application and remain unfrozen. A subsequent
+metadata fetch produces the library's frozen envelope and raw headers again; decoded data stays
+mutable. Select public response headers before sending metadata that contains private values.
+
+## Prepare the complete snapshot before continuing
+
+After prefetching finite queries, run `prepareViewSnapshot(serverQueryClient)` through the
+application's runner with `SnapshotEncoding` provided. Supply any asynchronous encoding work
+through `beforeEncode`, then await the returned JSON before publishing it through your framework.
+The original cache keeps decoded classes, bigint values, byte arrays, and page parameters.
+
+For an open HTTP or RPC stream, first await
+[fetchStreamSnapshot](/effect-api-query/guides/stream-snapshots/) with its exact generated stream
+options. It captures the first visible value and awaits local iterator cleanup. Keep exclusive
+ownership of that idle, unobserved key during capture. Only then prepare JSON and dispose the
+server's ready-client resources. Local cleanup does not acknowledge remote cancellation.
+
+On the browser, provide `SnapshotDecoding` and await `prepareViewHydration(browserQueryClient,
+json)` before querying or mounting observers. Encoding and decoding require separate services;
+one cannot satisfy the other. All selected data decodes before a single native `hydrate` call,
+so invalid codec data or an unknown codec ID leaves the browser cache untouched.
+
+This copied recipe accepts your own trusted server's native dehydrated envelope. It validates
+selected query data; it is not a validator for arbitrary external TanStack snapshots. Handle
+malformed JSON and preparation failures in the application's rendering or hydration error path.
+
+Only successful queries in the reserved family enter the snapshot. Mutations and failed-query
+errors/Causes are omitted. Hydration therefore leaves an omitted failed query available for a
+new browser fetch. Error hydration needs its own application-safe representation.
+
+Choose native freshness defaults to control duplicate reads. A successful fresh hydrated query
+can reuse its reconstructed data; later invalidation and refetch use the browser's independent
+ready client and the same decoded representation. For streams, explicit cached capture acquires
+no new work; fresh capture starts the browser stream again. Keep Effects and Promises outside
+query data and finish preparation before publishing or hydrating.

 A full snapshot rollback can erase a later successful write. The example instead removes a
 failed creation's own temporary user, or restores one deleted user without replacing the list.
+Overlapping deletions retain their original relative order, even when their failures finish in a
+different order. Rollback places the removed user beside surviving original neighbors and keeps
+newly created users.
 Overlapping deletions of the same user share the first snapshot: one successful deletion prevents
 an older failure from restoring it, while all failed deletions restore the original entity once.

+title: Refresh Reads from Domain Events
+description: Map domain delivery and Effect Reactivity to scoped native Query invalidation.
+---
+
+Use one application-owned consumer to map a domain event to the reads it changes. The mapping
+must name both adapters when RPC and HTTP represent the same domain: their generated cache roots
+remain separate.
+
+Copy [the user-event consumer](https://github.com/ueberBrot/effect-api-query/blob/main/tests/packed-consumer/user-events.ts)
+next to your owner, write, and client modules, adjusting its local application imports. Its inputs are the captured owner and
+an application-owned Effect Reactivity service. Supply your own decoded network stream; the module
+creates no connection, broker, provider, or second cache.
+
+## Register one consumer for the owner
+
+Acquire the consumer once in the owner's Scope. The following attachment accepts a supplied
+Effect Stream and preserves its failure and service requirements. Run its `consume` Effect with
+your application runtime and keep that Scope open across transport reconnects.
+
+```ts
+import { Effect, Stream } from 'effect'
+import type { Reactivity } from 'effect/reactivity'
+
+import { decodeUserEvent, makeUserEventConsumer } from './user-events.ts'
+import type { UserEventOwner } from './user-events.ts'
+
+export const attachUserEvents = Effect.fnUntraced(function* (
+  owner: UserEventOwner,
+  reactivity: Reactivity.Reactivity,
+) {
+  const consumer = yield* makeUserEventConsumer(owner, reactivity, {
+    observedUsers: [{ id: 1, locale: 'en' }],
+  })
+  const consume = <E, R>(events: Stream.Stream<unknown, E, R>) =>
+    events.pipe(
+      Stream.mapEffect((event) => decodeUserEvent(event)),
+      Stream.runForEach(consumer.deliver),
+      Effect.ensuring(Effect.promise(consumer.flush)),
+    )
+  return {
+    consumer,
+    consume,
+    latestDiagnostic: owner.rpcQuery.diagnostics.stream.liveOptions(),
+    diagnosticHistory: owner.rpcQuery.diagnostics.stream.streamedOptions({
+      maxChunks: 64,
+      refetchMode: 'reset',
+    }),
+  }
+})
+```
+
+`makeUserEventConsumer` rejects an inactive owner or a second consumer for the same QueryClient.
+Scope closure unregisters Reactivity handlers and the mutation-cache listener. Close the event
+Scope, retire the captured owner, and await its disposal before replacing clients; remount the
+React consumers as described in [Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/).
+
+A closed or retired consumer ignores queued delivery and invalidation callbacks. It retains its
+original QueryClient and cannot redirect an old event to a replacement client. A refresh already
+started belongs to the native query lifecycle; owner retirement cancels those reads and awaits
+local cleanup before releasing ready clients.
+
+## Map events to reads
+
+The `users.v1` envelope includes the consumer's `ownerKey`, a positive safe-integer cursor, and one
+of these event kinds:
+
+| Event                                  | Reads invalidated                                                 |
+| -------------------------------------- | ----------------------------------------------------------------- |
+| `users.changed`                        | RPC and HTTP list/page prefixes, including infinite page entries. |
+| `user.changed`, with `id` and `locale` | Those directory prefixes and both exact user-detail keys.         |
+| `users.reset`                          | Both complete user branches.                                      |
+
+Other user IDs, locales, and diagnostic branches remain untouched by an ordinary detail event.
+Generated keys and native filters retain the owning QueryClient's global and prefix hash defaults.
+The mapping depends on the domain relationship, so the package does not infer it from mutation or
+event names.
+
+The `ownerKey` contains safe tenant, user, session, and permission-generation identity. It is a
+routing partition, not authentication. The application must authenticate the transport and
+validate which owner may receive each event.
+
+## Coalesce local invalidation
+
+Use the consumer's `reactivityKeys.directory`, `reactivityKeys.all`, or
+`reactivityKeys.user({ id, locale })` with Effect Reactivity. Exact local user mappings exist for
+the `observedUsers` registered when the consumer starts; include every detail read your local
+writers must refresh. Delivered domain events can target any valid user.
+
+These keys are stable application strings. Reactivity hashes its own keys; a TanStack query tuple
+has no implied Reactivity subscription or prefix relationship. Register the deliberate mapping
+rather than passing generated tuples to both systems.
+
+Reactivity `withBatch` combines repeated invalidations of the same key. Distinct keys can still
+invoke distinct handlers. The consumer collects their intent in one microtask and lets a full
+user-branch refresh subsume narrower work. It merges more than 64 pending detail identities into
+a full refresh, bounding delivery bookkeeping. Events received during a refresh form the next
+batch.
+
+Refreshes wait while the captured QueryClient has pending mutations, so an event does not start a
+read over an optimistic write. The scoped mutation listener schedules retained intent when those
+writes settle. Use the same QueryClient for these writes and follow
+[Optimistic User Writes](/effect-api-query/guides/optimistic-writes/). Coordinate external writes
+and other manual refresh paths through your own application policy.
+
+`flush()` awaits currently runnable batches. During a pending mutation it leaves intent queued
+until settlement. `onRefreshError` receives failures from the refresh job; ordinary native query
+failures retain TanStack's query/error state and retry policy. The default refresh-job handler
+reports the error to the console.
+
+## Resume delivery deliberately
+
+This recipe assumes one ordered, monotonically increasing cursor sequence per owner. It ignores
+cursors already accepted. A gap queues a full user-branch refresh and advances the accepted cursor.
+The cursor records accepted invalidation intent; it is not a durable acknowledgement or a claim
+that a read succeeded.
+
+Reconnect using `consumer.cursor()` as the last accepted cursor. Call `consumer.resume(true)` when
+the transport can replay subsequent events in order. Replayed duplicates remain harmless. If
+replay is unavailable, call `consumer.resume(false)` before accepting the new sequence: it resets
+the cursor and refreshes both user branches. Stop delivery from the old connection first.
+
+The application owns reconnect backoff, replay retention, cursor storage, source epochs, schema
+migration, authorization, acknowledgements, and out-of-order delivery handling. A new owner Scope
+starts at cursor zero. Fetch its authoritative reads on startup; this recipe does not promise
+durable or exactly-once delivery. Invalid envelopes fail Schema decoding before changing the cursor.
+
+## Choose a visible stream view
+
+The example's diagnostic stream emits complete diagnostic values. `latestDiagnostic` uses a live
+query; `diagnosticHistory` keeps at most 64 values with reset refetch behavior. Use the same choices
+for an indefinitely running state stream: live queries require complete snapshots, while a bounded
+accumulated query can display a recent event history.
+
+An accumulated query with `refetchMode: 'replace'` publishes its replacement only when the refetch
+stream completes. An indefinite stream may never publish that replacement. Use a live full
+snapshot or a bounded history with a visibility policy suited to the UI. A live query containing
+only the latest delta does not reconstruct domain state.
+
+Native `Stream.runForEach` runs the supplied stream, and generated keys serve native Query filters.
+Keep delivery, replay, and owner policy in the application consumer so its runtime and Scope remain
+explicit.

+
+Server rendering uses request-owned connections built with Effect's public decoded-message client
+and server. They execute the same application state as the network handlers. RPC execution avoids
+HTTP round trips; HTTP loaders call the host's Web handler in process and retain HTTP Schema codecs.
+The browser acquires separate network clients and reconnects both stream views after hydration.
+
+Local RPC middleware captures the request's demonstration authorization value. Per-call headers and
+caller execution services cannot replace that authority. The example defaults that public value to
+`allowed`; replace this demonstration policy with your application's authentication. Decoded-message
+RPC execution bypasses transport Schema codecs. Keep a schema-aware protocol when wire validation
+or codec effects are required.
+
+The example pairs Schema encoding and decoding for its directory, pages, diagnostic history and
+live values. It awaits encoding before publishing the initial snapshot and each streamed batch,
+and awaits decoding of an entire batch before native hydration. Request disposal interrupts
+preparation and awaits its finalizers before releasing the clients. Serialization callbacks stay
+synchronous. Failed queries remain omitted. Its copied map covers the example's own generated
+key families; add an explicit codec when you add another hydratable view. See
+[Hydrate Query Views](/effect-api-query/guides/hydrate-query-views/) for page parameters, richer values
+and application-owned preparation services.

+title: Vue and Solid Query
+description: Rebuild generated options from reactive input and keep client resources alive.
+---
+
+Pass generated options from either factory to the framework's native Query hooks. Configure
+`VueQueryPlugin` in Vue or `QueryClientProvider` in Solid, and acquire the ready client before
+creating the utilities. Keep its `Scope` and any serviceful runner alive while queries use them.
+
+| Framework | Framework version | Query wrapper and matching Query Core |
+| --------- | ----------------- | ------------------------------------- |
+| Vue       | 3.5.43            | 5.103.1 and 5.104.0                   |
+| Solid     | 1.9.15            | 5.103.1 and 5.104.0                   |
+
+These combinations use Effect 4.0.0 with strict TypeScript 5.9.3 and 7.0.2. The same generated
+builders provide selection, defined initial data, skipping, mutations, pagination, accumulated
+streams, live values, and HTTP metadata views. See the
+[compatibility reference](/effect-api-query/reference/compatibility-and-limits/) for the wider scope.
+
+## Rebuild options when input changes
+
+Builders capture plain input when called. Build options inside Vue `computed` or Solid's options
+accessor so a changed input produces a new key and query function. Passing a builder's result
+once leaves the query attached to the original input.
+
+In Vue component setup, use a computed options object. This example assumes `rpc.users.read`
+returns a user with a `name`:
+
+```ts
+import type { InferDataFromTag, InferErrorFromTag } from '@tanstack/query-core'
+import { useQuery } from '@tanstack/vue-query'
+import { skipToken } from 'effect-api-query'
+import { computed, ref } from 'vue'
+
+const userId = ref<number | undefined>(1)
+const options = computed(() =>
+  rpc.users.read.queryOptions({
+    input: userId.value === undefined ? skipToken : { id: userId.value },
+    select: (user) => user.name,
+  }),
+)
+const user = useQuery<
+  InferDataFromTag<unknown, typeof options.value.queryKey>,
+  InferErrorFromTag<Error, typeof options.value.queryKey>,
+  string
+>(options)
+```
+
+Read the selected value from `user.data.value`. The explicit native hook generics preserve the
+data and error carried by the generated key while bounding Vue's recursive ref unwrapping.
+Automatic inference can otherwise exceed TypeScript's instantiation depth when it unwraps an
+Effect `Cause` through a tagged key. Let the builder infer its arguments; put these type arguments
+on the Vue hook.
+
+In a Solid component, pass the builder call as an accessor:
+
+```ts
+import { useQuery } from '@tanstack/solid-query'
+import { skipToken } from 'effect-api-query'
+import { createSignal } from 'solid-js'
+
+const [userId] = createSignal<number | undefined>(1)
+const user = useQuery(() => {
+  const id = userId()
+  return rpc.users.read.queryOptions({
+    input: id === undefined ? skipToken : { id },
+    select: (value) => value.name,
+  })
+})
+```
+
+Read the selected value from `user.data`. Apply the same computed/accessor pattern to
+`infiniteOptions`, `streamedOptions`, `liveOptions`, and `metadataOptions` when their input changes.
+
+## Choose native options carefully
+
+Vue evaluates a function-valued `enabled` as a getter with no arguments. Use a boolean inside
+computed options, or a zero-argument getter returning a boolean. A Core `enabled(query)` callback
+cannot be passed directly to Vue. Solid accepts the native Core callback.
+
+The pinned Solid query and infinite-query overloads accept defined initial data or absent initial
+data. A value or initializer that may return `undefined` does not match those overloads. Omit
+`initialData` or supply a defined seed. Vue accepts a possibly undefined initializer. An explicit
+`initialData: undefined` still overrides inherited QueryClient initial data in both integrations.
+
+## Own streams and disposal
+
+Open streams expose their first value while fetching continues. Changing reactive input replaces
+the query; when its last observer leaves, query cancellation closes the stream iterator. Component
+unmount or Solid owner disposal also releases observed streams. Keep client resources alive until
+these queries finish cancelling, then clear the owned QueryClient and close the client scope.
+Transport interruption depends on the ready client.
+
+Use `streamedOptions` for an accumulated history and `liveOptions` for its latest emission. HTTP
+`metadataOptions` retains decoded data, response status, and header snapshots in a separate cache
+entry. Follow [client lifecycle](/effect-api-query/concepts/client-lifecycle/) and
+[cancellation](/effect-api-query/guides/cancellation/) when disposing the cache owner.

+title: Svelte and Angular
+description: Rebuild generated options when reactive inputs change and keep client lifetime in the application.
+---
+
+Pass generated options through the framework's reactive accessor. Each builder captures its
+plain input when called, so create the options inside that accessor whenever the input can change.
+The same rule applies to RPC and HTTP queries, metadata views, accumulated streams, and live queries.
+
+## Svelte
+
+Create the utility tree in your application module from an acquired ready client. Provide a
+QueryClient through Svelte Query's `QueryClientProvider`, then read reactive inputs inside the
+accessor passed to `createQuery`:
+
+```svelte
+<script lang="ts">
+  import { createQuery } from '@tanstack/svelte-query'
+  import { rpc } from './api'
+
+  let id = $state(1)
+  const user = createQuery(() =>
+    rpc.users.read.queryOptions({
+      input: { id },
+      select: (user) => user.name,
+    }),
+  )
+</script>
+
+<button onclick={() => id += 1}>Next user</button>
+<p>{user.data}</p>
+```
+
+Use `createInfiniteQuery(() => rpc.users.list.infiniteOptions(...))` for pagination and
+`createMutation(() => rpc.users.write.mutationOptions(...))` for writes. A mutation's variables
+provide the input for each execution. Mutation options can be static when their callbacks and
+other settings do not depend on reactive state.
+
+Compile the Svelte application with `module: "ESNext"` and `moduleResolution: "Bundler"`.
+The supported Svelte Query releases require this resolution for their emitted `.svelte`
+declarations; strict NodeNext declaration checking reports an upstream `Box` import error.
+
+## Angular
+
+Register `provideTanStackQuery(queryClient)` in your application providers. Construct queries
+inside an Angular injection context and read the signal inside the accessor passed to `injectQuery`.
+The ready client below is acquired and disposed by the application:
+
+```ts
+import { Component, signal } from '@angular/core'
+import { injectQuery } from '@tanstack/angular-query-experimental'
+import { Schema } from 'effect'
+import { createRpcQueryUtils } from 'effect-api-query'
+import { Rpc, RpcGroup, type RpcClient } from 'effect/rpc'
+
+const group = RpcGroup.make(
+  Rpc.make('users.read', {
+    payload: { id: Schema.Int },
+    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+  }),
+)
+declare const client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof group>>
+const rpc = createRpcQueryUtils(group, { client, keyPrefix: ['current-owner'] })
+
+@Component({
+  selector: 'user-details',
+  standalone: true,
+  template: '<button (click)="next()">Next user</button><p>{{ user.data() }}</p>',
+})
+export class UserDetails {
+  readonly id = signal(1)
+  readonly user = injectQuery(() =>
+    rpc.users.read.queryOptions({
+      input: { id: this.id() },
+      select: (user) => user.name,
+    }),
+  )
+
+  next() {

+
+Use `injectInfiniteQuery` and `injectMutation` with the corresponding builders. Angular query
+results expose signals such as `data()`, `error()`, and `fetchStatus()`.
+
+Angular's defined-data overload accepts a query function rather than `skipToken`. A skipped query
+therefore retains `undefined` in its `data()` type even when it has defined `initialData`. Svelte
+preserves the defined-data type for that combination. Both frameworks accept initial-data functions
+that may return `undefined`, with optional result data.
+
+## Own the lifecycle
+
+Changing a generated query's key replaces the observer's active query. Unmounting a Svelte
+component or destroying an Angular component removes its observers; the last observer of an
+abort-aware open stream triggers cancellation. Keep the ready client and runtime alive until
+local stream finalizers finish. Other observers of the same query retain their subscription.
+
+For an owner change, unmount the old tree, cancel and clear its QueryClient, await local cleanup,
+then dispose its client resources. Mount the new tree with independently owned resources and a
+safe key prefix. See [Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/) and
+[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/).

+
+Angular core, common, compiler, and platform-browser use the same release, with RxJS 7.8.2.
+The published option contract supports TypeScript 5.9.3 and 7.0.2 with strict checking; choose a
+compiler release supported by your framework's build tooling. Framework query wrappers
+must share the application's Query Core version. This scope covers browser components; framework
+server rendering and hydration need their own application integration.

+title: Browser and Worker Hosts
+description: Framework-free browser and dedicated worker coverage, ready-client ownership, and transport limits.
+---
+
+The package root executes generated RPC and HTTP operations in browser windows and dedicated
+workers. Both hosts use the same factories and TanStack Query Core options. Each host acquires
+its own ready clients and owns their `Scope`, runner, QueryClient, and disposal.
+
+## Host and operation coverage
+
+The current host matrix uses Effect 4.0.0, Query Core 5.103.1 and 5.104.0, and Playwright 1.63.0.
+Chromium 153.0.8010.12 and Firefox 155.0 execute every operation below in both a window and a
+dedicated worker.
+
+| Operation or behavior      | RPC                                          | HTTP                                                                  |
+| -------------------------- | -------------------------------------------- | --------------------------------------------------------------------- |
+| Buffered reads and writes  | Generated unary queries and mutations        | Generated queries and mutations with native request/response encoding |
+| Accumulated streamed query | Ordered values from a ready RPC client       | Decoded SSE values from a ready HTTP API client                       |
+| Live query                 | Latest emitted value                         | Latest decoded SSE value                                              |
+| Declared response headers  | Outside the RPC contract                     | Preserved decoded header wrappers                                     |
+| Metadata view              | Outside the RPC contract                     | Decoded data, status, and immutable raw header snapshot               |
+| Conditional query sentinel | Consumer Query Core `skipToken` binding      | Consumer Query Core `skipToken` binding                               |
+| Independent cache owners   | Separate clients, prefixes, and QueryClients | Separate clients, prefixes, and QueryClients                          |
+| Cancellation and disposal  | Stream finalization before client disposal   | Stream finalization before client disposal                            |
+
+The RPC host coverage uses an in-process decoded-message ready client. HTTP coverage uses the
+native in-process routing, response encoding, and client decoding pipeline, including SSE. These
+hosts do not certify a network transport, browser authentication scheme, service worker, shared
+worker, or cross-host cache protocol.
+
+## Own the worker lifetime
+
+Create a utility tree inside the worker after acquiring its ready client. Run queries and maintain
+their QueryClient in that worker. Messages to the window may carry application DTOs or events;
+the utility tree, client, Effect runtime, and QueryClient remain owned by their host.
+
+On shutdown, stop accepting work, cancel the owner's queries, and await the application's active
+stream finalizers and accepted mutations before clearing private cache data and closing the
+client's `Scope`. Native query cancellation can settle before asynchronous finalizers finish.
+Wait for application-owned cleanup acknowledgements before terminating the worker. Disposing one
+owner must not close another owner's clients or cancel its queries.
+
+See [client lifecycle](/effect-api-query/concepts/client-lifecycle/) and
+[cancellation](/effect-api-query/guides/cancellation/) for the shared ownership contract.
+
+## Worker transport boundary
+
+A worker hosting ready-client queries is distinct from a window sending Effect RPC requests to
+a worker over `postMessage`. The latter is not certified by this matrix.
+
+Effect exposes worker protocols through `effect/rpc` and worker services through `effect/workers`.
+`RpcClient.layerProtocolWorker` requires application-supplied `WorkerPlatform` and `Spawner`
+services. The server's worker protocol requires `WorkerRunnerPlatform`. The package supplies none
+of these services and does not construct a worker transport. A browser worker transport needs a
+compatible platform integration and its own acquisition, interruption, and disposal contract.
+Supplying an already acquired client preserves the factories' existing ready-client boundary.

+title: WebSocket ready clients
+description: Acquire a shared RPC connection and keep cancellation and replacement application-owned.
+---
+
+Acquire a flat Effect RPC client inside an application Scope, then pass it to
+`createRpcQueryUtils`. The same connection can carry concurrent unary requests,
+accumulated streamed queries, and live queries. Each request retains its own query key
+and cancellation.
+
+## Acquire the connection
+
+Save this module as `socket-client.ts`, and replace `socketGroup` with your shared contract.
+Keep the parent Scope alive while any returned utility is in use. The child Scope owns
+the socket, protocol, ready client, and QueryClient cleanup.
+
+```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Effect, Exit, Layer, Schema, Scope } from 'effect'
+import { createRpcQueryUtils } from 'effect-api-query'
+import { Rpc, RpcClient, RpcGroup, RpcSerialization } from 'effect/rpc'
+import { Socket } from 'effect/socket'
+
+export const socketGroup = RpcGroup.make(
+  Rpc.make('values.read', { payload: { id: Schema.Int }, success: Schema.Int }),
+  Rpc.make('values.watch', {
+    payload: { channel: Schema.String },
+    success: Schema.Int,
+    stream: true,
+  }),
+)
+
+export const acquireSocketQueries = Effect.fn('acquireSocketQueries')(function* (
+  url: string,
+  owner: string,
+) {
+  const clientScope = yield* Scope.fork(yield* Effect.scope, 'sequential')
+  const socket = yield* Socket.makeWebSocket(url).pipe(Scope.provide(clientScope))
+  const protocol = yield* Layer.buildWithScope(
+    RpcClient.layerProtocolSocket().pipe(
+      Layer.provide(RpcSerialization.layerJson),
+      Layer.provide(Layer.succeed(Socket.Socket, socket)),
+    ),
+    clientScope,
+  )
+  const client = yield* RpcClient.make(socketGroup, { flatten: true }).pipe(
+    Effect.provide(protocol),
+    Scope.provide(clientScope),
+  )
+  const queryClient = new QueryClient({ defaultOptions: { queries: { retry: false } } })
+  const rpc = createRpcQueryUtils(socketGroup, { client, keyPrefix: ['socket', owner] })
+  yield* Scope.addFinalizer(
+    clientScope,
+    Effect.promise(async () => {
+      await queryClient.cancelQueries()
+      queryClient.clear()
+    }),
+  )
+  return { client, rpc, queryClient, dispose: Scope.close(clientScope, Exit.void) }
+})
+```
+
+Supply a WebSocket constructor for the host. Browsers can use
+`Socket.layerWebSocketConstructorGlobal`; Node applications can supply the existing
+`NodeSocket.layerWebSocketConstructorWS` from `@effect/platform-node`.
+The server must expose the matching group through `RpcServer.toHttpEffectWebsocket`
+and use the same serialization. This recipe uses JSON on both ends.
+
+## Read and capture stream data
+
+The following browser function runs two unary reads, then captures the first successful
+value from each stream view. Run it within a caller-owned Scope. `fetchStreamSnapshot`
+stops and drains local iterator work before returning, so an open stream can supply a
+snapshot without waiting for completion.
+
+```ts
+import { Effect } from 'effect'
+import { fetchStreamSnapshot } from 'effect-api-query'
+import { Socket } from 'effect/socket'
+
+import { acquireSocketQueries } from './socket-client.ts'
+
+export const readSocketSnapshot = Effect.fn('readSocketSnapshot')(function* (url: string) {
+  const application = yield* acquireSocketQueries(url, 'account-42').pipe(
+    Effect.provide(Socket.layerWebSocketConstructorGlobal),
+  )
+  const { queryClient, rpc } = application
+  try {
+    const reads = yield* Effect.promise(() =>

+```
+
+For a long-lived UI, give the generated `streamedOptions` or `liveOptions` to a native
+observer instead. Its first emission becomes successful query data while `fetchStatus`
+remains `fetching`. Accumulated streams preserve history; live queries retain the latest
+value. `maxChunks` controls cached history, and `rpcOptions.streamBufferSize` controls
+the ready client's transport queue. They govern different resources.
+
+## Cancel and replace an owner
+
+Cancel one stream with its generated exact key, for example
+`cancelQueries({ queryKey: options.queryKey, exact: true })`. Other stream keys and
+concurrent unary calls continue on the same connection. TanStack retains its native
+cancellation result: after a stream has published data, cancellation can settle its
+query promise successfully with cached data.
+
+Call `application.dispose` before disposing the server or an enclosing runtime. The
+registered finalizer cancels queries and clears their cache before the client and socket
+close. For a replacement owner, await disposal, acquire a new application Scope and
+ready client, and construct a new QueryClient. The same semantic prefix can produce
+the same keys while resource lifetimes and cache instances remain independent. Follow
+[owner-switching rules](/guides/switch-cache-owners/) when authentication changes.
+
+Replacement acquires a new connection. Transport reconnection, backoff, credentials,
+event replay, and whether failed queries retry belong to the application and Effect's
+transport configuration. Reconnection does not imply that a cancelled stream resumes
+from its last cached event.
+
+## Interpret cancellation and failures
+
+The WebSocket transport forwards an interrupted request to the RPC server. Cooperative
+handler finalizers were observed on this transport for both stream views. A local abort
+signal or idle query state alone cannot prove remote completion; use a domain
+acknowledgement when an application must wait for server work to stop. Closing a
+connection immediately after cancellation can race delivery of that interrupt.
+
+An independent server interruption remains an `EffectRpcQueryError`, even when TanStack
+has not cancelled the query. Its Cause preserves the failure received by the ready client;
+wire serialization can change the original server's Cause representation. A failed stream
+leaves already published data available alongside its error.
+
+With Effect 4.0.0, cancelling a paused stream with a full transport buffer of size 1 can
+stall other calls on the connection. This recipe uses the native default of 16. Verify
+smaller buffers against the pinned transport version before changing that setting.
+
+Query cancellation stops future work cooperatively. It does not undo completed writes;
+use an [explicit cancellable command](/guides/cancellation/) when the domain requires one.

+title: External HTTP Clients
+description: Generated OpenAPI consumers, encoded request values, multipart uploads, and raw SSE limits.
+---
+
+An external HTTP client can call an Effect HttpApi server through its declared HTTP contract.
+The supported combination is `openapi-fetch` 0.17.0 with `openapi-typescript` 7.13.0 and Effect 4.0.0.
+Generate `paths` from the JSON document returned by native `OpenApi.fromApi(api)`.
+
+`createHttpApiQueryUtils` accepts a ready Effect HttpApiClient. Keep that client and its runner
+native; the external Promise client calls HTTP independently. This interoperability does not
+establish compatibility with the Effect RPC wire protocol.
+
+## Encoded and decoded values
+
+OpenAPI describes encoded HTTP values. An endpoint using `Schema.NumberFromString` accepts a
+string on the wire and a number through the ready Effect client. A generated external client
+returns a plain encoded DTO; native Schema decoding constructs the domain value.
+The external client's generated types add no runtime Schema decoding or validation.
+
+| Value                   | External client                   | Ready Effect client                                           |
+| ----------------------- | --------------------------------- | ------------------------------------------------------------- |
+| Request path parameter  | `params.path.id: '5'`             | `params.id: 5`                                                |
+| Request query parameter | `params.query.limit: '2'`         | `query.limit: 2`                                              |
+| Declared request header | `params.header['x-factor']: '3'`  | `headers['x-factor']: 3`                                      |
+| JSON request payload    | `body.amount: '7'`                | `payload.amount: 7`                                           |
+| Response body           | Plain object with `total: '17'`   | Schema class with `total: 17` and methods                     |
+| Response headers        | Raw strings on `response.headers` | Decoded declared header wrapper; raw strings in metadata view |
+
+## Buffered requests and uploads
+
+The report contract below declares `POST /reports/:id`, a JSON payload, query and header fields,
+and a 203 response. Its missing-report response has status 404 and a tagged JSON body. An update
+uses `PATCH` and declares a 409 conflict. Read declared failures through `error` and inspect
+`response.status`; the external client does not construct an Effect execution-error wrapper.
+
+Array query parameters use repeated names, including a single-element array. JSON array
+responses retain their ordinary JSON representation. This scope does not include GET payloads
+or form-urlencoded payloads.
+
+For `multipart/form-data`, map a binary schema to `Blob` with the generator's `transform` hook.
+Use a `bodySerializer` that returns `FormData`. Let Fetch set the multipart boundary; the default
+JSON serializer receives HTTP 415 from a multipart-only endpoint. The example upload includes
+path/query/header values, a text field, and a file with its filename and contents intact.
+
+```ts
+import createClient from 'openapi-fetch'
+
+import type { paths } from './openapi-generated.ts'
+
+const external = createClient<paths>({ baseUrl: 'https://api.example.test' })
+const report = await external.POST('/reports/{id}', {
+  params: {
+    path: { id: '5' },
+    query: { limit: '2', labels: ['a b', 'c+d'] },
+    header: { 'x-factor': '3' },
+  },
+  body: { amount: '7', title: 'Quarter 1' },
+})
+if (report.error) {
+  throw new Error(`Report failed with HTTP ${report.response.status}`)
+}
+const revision = report.response.headers.get('x-revision')
+
+const uploaded = await external.POST('/reports/{id}/files', {
+  params: {
+    path: { id: '5' },
+    query: { revision: '3' },
+    header: { 'x-kind': 'document' },
+  },
+  body: { title: 'Notes', file: new File(['contents'], 'notes.txt') },
+  bodySerializer: (body) => {
+    const form = new FormData()
+    form.set('title', body.title)
+    form.set('file', body.file)
+    return form
+  },
+})
+const events = await external.GET('/reports/events/{channel}', {
+  params: { path: { channel: 'values' } },
+  parseAs: 'stream',
+})
+export { events, report, revision, uploaded }
+```
+
+The external client's `Response` retains HTTP status and raw headers after buffering. The native
+HTTP metadata view retains decoded data with immutable plain status/header snapshots. These
+are distinct representations.
+
+## SSE boundary
+
+`parseAs: 'stream'` returns a raw `ReadableStream<Uint8Array>`. It does not parse events, decode
+Schema values, or turn a reserved failure event into an error. Default JSON parsing fails on
+an SSE response.
+
+Effect's SSE data mode encodes each value as JSON in an event's `data` field. A custom event can
+also carry `id` and `event`. A stream failure uses the reserved event name
+`effect/http-api/stream/failure` and an encoded Cause body while HTTP status remains 200.
+The generated document records these details in `x-effect-stream`; this client does not consume
+that extension. Typed SSE consumption requires the native ready Effect client or an
+application-owned compatible decoder. Raw stream access alone gives no typed SSE guarantee.
+
+See the [external client's API](https://openapi-ts.dev/openapi-fetch/api) and
+[generator's Node API](https://openapi-ts.dev/node) for their configuration.

+title: Choose Stream History
+description: Choose retained history, transport buffering, and update rates for long-running streams.
+---
+
+Choose the cached representation from what the screen needs:
+
+| Need                         | Builder                            | Retained data                                 |
+| ---------------------------- | ---------------------------------- | --------------------------------------------- |
+| Every emitted value in order | `streamedOptions`                  | Unlimited history by default.                 |
+| A recent event window        | `streamedOptions` with `maxChunks` | Up to the specified number after an emission. |
+| Current state                | `liveOptions`                      | The latest emitted value.                     |
+
+For a long-running event display, choose a finite `maxChunks`. For current progress or a full-state
+feed, choose a live query. Unlimited accumulation grows with the number of emissions; it suits
+finite histories or workloads where that growth is deliberate. Persist durable history outside
+the query cache when it must survive cache eviction or application restarts.
+
+These choices apply to both RPC streams and supported HTTP SSE endpoints. Live queries normalize
+successful `undefined` to `null`; accumulated histories preserve their emitted values.
+
+## Set retention and buffering separately
+
+`maxChunks` limits the number of cached elements after each new emission. Seeded or hydrated history
+can exceed the bound until another element arrives. One element can contain a large object or array,
+so this bound does not limit bytes. It discards older elements while preserving the remaining order.
+Use the same retention and refetch policy when building an exact key and its options.
+
+RPC `rpcOptions.streamBufferSize` controls the ready client's transport buffer before consumption.
+It does not set cache history or the rate of cache writes. HTTP transport buffering belongs to
+the ready HTTP API client. Changing a history bound does not slow the producer.
+
+An initial accumulated or live fetch exposes its first value while the stream remains open.
+An accumulated `replace` refetch publishes its replacement only after successful completion;
+an indefinitely open replacement therefore keeps showing the previous history. See
+[Stream Snapshots](/effect-api-query/guides/stream-snapshots/) for finite server captures.
+
+## Assess writes and references separately
+
+Accumulated streams publish immutable arrays. A history bound limits their length; each consumed
+value still contributes to cache updates. Live queries also accept each value, including repeated
+values. Native structural sharing can preserve equal data references without suppressing those
+cache writes.
+
+For JSON-compatible values, TanStack's default structural sharing can reuse unchanged objects and
+nested values. A moving window changes array positions, so sharing can also produce additional
+distinct references. Compare the data shape your application receives before choosing
+`structuralSharing: false` or a custom native policy.
+
+Cache notifications also include query creation and fetch lifecycle changes. Count data writes,
+data reference changes, and retained elements separately. Framework observer selection and
+render scheduling add their own behavior; cache notification counts do not count component renders.
+
+If the producer outruns the interface, set an explicit rate or sampling policy in the producer or
+an application-owned Effect Stream transformation. Sampling intentionally discards values.
+Retention and transport buffering serve different purposes from publication rate.
+
+## Repeat the repository baseline
+
+From a repository checkout with its dependencies available, run:
+
+```sh
+STREAM_MEASURE=/tmp/stream-baseline.json vp run --no-cache test tests/create-rpc-query-utils-stream-baseline.test.ts
+```
+
+The command replaces the chosen JSON file. It compares 64 numeric or object emissions across
+unlimited history, windows of four and sixteen elements, and live values, with native structural
+sharing enabled and disabled. Each case uses a fresh QueryClient and a finite in-memory ready
+RPC client, with no framework observers.
+
+The report records dependency versions, source and workload fingerprints, cache notifications,
+data writes, changed references, and retained sequences. It separates the stream's manual cache
+writes from the final successful fetch write. Array-slot and object-reference counts
+describe values observed at the cache boundary. They do not measure total allocation, heap size,
+garbage collection, network throughput, or browser rendering time. Use the same workload and
+toolchain when comparing changes, then measure any rendering concern in the application that has it.

 ## Supported integrations
 
+See [Performance and Bundling](/effect-api-query/reference/performance/) for construction costs,
+repeatable compiler measurements, and adapter versus application bundle sizes.
+
 The package targets Effect 4 and TanStack Query Core 5.103.1 or later in v5, with React Query and TanStack Start
 integrations checked in this repository. It is ESM-only and targets ES2022. Use TypeScript with
 `strict: true`.

+title: Performance and Bundling
+description: Construction costs, compiler measurements, and the distinction between adapter and application bundles.
+---
+
+## Construction
+
+Factories eagerly build and freeze the complete RPC or HTTP utility tree. Build each tree once
+for its ready client and cache owner. A larger contract increases factory work even when an
+application uses only a few leaves.
+
+Payload-bearing keys prepare a fresh immutable canonical payload. RPC preparation constructs
+and Schema-encodes the normalized payload; HTTP preparation encodes the declared request parts.
+Larger payloads increase this work. Option builders also capture the request and create a fresh
+query function. Repeated calls do not memoize payloads or option objects.
+
+A custom RPC key encoder replaces Schema encoding. Payload construction, JSON validation,
+canonical copying, and freezing still run. Choose an encoder for correct semantic identity;
+it must preserve every input field that can change the result.
+
+## Repeatable measurements
+
+Maintainers can save a report while verifying the packed package:
+
+```sh
+EFFECT_API_QUERY_BASELINE=.artifacts/packed-baseline.json vp run packed-package
+```
+
+The report identifies the exact archive, runtime, peers, compiler versions, and source hashes.
+Construction measurements use one or 250 operations and inputs containing one or 100 records.
+Each stage reports five samples after warm-up, with factory construction separate from key and
+option construction. RPC payload construction and Schema encoding also have separate samples;
+the custom-encoder key measurement still includes the package's normal preparation.
+
+Compiler reports separate the public contract, 250 RPC operations, and 250 HTTP endpoints under
+both supported consumer compilers. A cold compiler process starts without an incremental build
+file, then an unchanged incremental process reuses it. This does not reset operating-system caches.
+Type and instantiation counts help compare declaration changes when the inputs and versions match.
+Local elapsed time and memory measurements are observations, not performance guarantees or
+universal regression thresholds.
+
+## Adapter and application bundles
+
+The package marks its exports as free of side effects and keeps Effect and Query Core as peers.
+An application can import one factory or an error guard from the package root. Unused factories
+and the stream snapshot helper can then be removed by the bundler.
+
+The report builds an error-guard import, an RPC-factory import, and an HTTP-factory import with
+Vite's Oxc minifier and an ES2022 target. Each probe has two sizes:
+
+| Peer treatment | What the size includes                                               |
+| -------------- | -------------------------------------------------------------------- |
+| External       | Retained package code and peer imports; dependency code is excluded. |
+| Included       | Retained package code and the peer code needed by that import.       |
+
+Sizes include JavaScript bytes and gzip bytes at compression level nine. An error guard can
+eliminate all peer code in the included probe, while an external probe retains bare peer imports
+whose side effects the bundler cannot inspect. The included size can therefore be smaller for
+that probe.
+
+These probes measure one retained package export. An application's contract Schemas, transport,
+QueryClient, framework, and other imports change its final bundle. Compare reports from the same
+probe and dependency versions before attributing a size change to the adapter.

 ## Agent skills
 
+### Shipped library skill
+
+When changing public behavior, usage documentation, or shipped guidance, run
+`vp exec intent meta generate-skill` and follow the installed maintenance procedure.
+Read the shared [planning record](_artifacts/skill_spec.md); maintain its domain map
+and skill tree alongside the affected guidance. Run `vp exec intent maintainer sync`,
+review actual source changes with `vp exec intent maintainer review --json`, and
+record justified outcomes for the owned skill, planning, and source items after
+task checks. Leave unrelated skills unresolved. Finish with `vp run skills-check`.
+

+    covers:
+      - RPC construction and canonical identity
+      - HTTP decoded requests, SSE, multipart mutations, and metadata
+      - Native defaults, filters, skipping, and pagination
+      - Stream policies, snapshots, and request cleanup
+      - Optimistic overlap, event refresh, and owner replacement
+      - DTO and rich-value hydration
+      - Reactive framework accessors and host boundaries
+    tasks:
+      - Derive buffered, paginated, accumulated, live, and metadata options from a ready client.
+      - Address exact stream policy keys and compose encoded partial native filters.
+      - Apply native defaults without losing selected or explicitly undefined seed behavior.
+      - Capture open streams and drain preparation before request disposal.
+      - Hydrate every selected view into its normal decoded cache representation.
+      - Preserve neighboring writes and originating ownership during mutation overlap.
+      - Defer event refresh until participating writes settle.
+      - Retire consumers and accepted work before acquiring a replacement owner.
+      - Rebuild options inside native reactive framework accessors.
+      - Choose an application-owned transport within verified version and host limits.

+# Effect API Query skill coverage
+
+The package derives TanStack Query utilities from Effect RPC and HTTP contracts and
+ready clients. Applications retain transport, authentication, runtime, Scope, cache
+ownership, and serialization policy.
+
+## Domains and inventory
+
+| Domain                           | Skill            | Type | Coverage                                                                                                                     |

+
+The existing single skill remains automatically discoverable through the package.
+Its entry point holds shared rules and routes tasks to RPC, HTTP, query patterns,
+cache workflows, hydration/SSR, and framework/host references. Consumers need no
+authoring tools or repository-local agent skills to use this guidance.
+
+## Failure modes
+
+| Mistake                                               | Priority | Source                                            |

+
+The domain map records mechanisms and task coverage. The skill tree owns paths and
+source mappings. Public declarations and runtime own API facts; tested application
+modules and guides own recommended cache and lifecycle recipes.
+
+## Decisions and boundaries
+
+- Preserve one library skill rather than introducing prerequisite or framework
+  skills for existing branches. Conditional references avoid loading every workflow.
+- Migrate the original description to purpose, then apply the approved correction
+  for the settled HTTP and framework scope. Keep activation task-oriented and
+  record the verified package version, currently 0.0.0.
+- Keep package-only distribution. Planning records and review state remain outside
+  shipped skills and the package allowlist.
+- Keep scoped native skill validation in the existing uncached task and CI path.
+  Record revision-bound source and planning reviews with actual task evidence.
+  Repository-wide native review also selects unrelated local authoring skills,
+  so it cannot serve as this library skill's CI gate. Preserve those unresolved
+  items and the existing pinned installer semantics.
+- Keep the audited coordinated Effect 4.0.0 set. Default buffer-16 cancellation has
+  a passing full-queue/concurrent-unary control; overflowing buffer-one, chunk Schema
+  isolation, and single-element GET/form payload-array limitations remain explicit.
+- Add no clients, providers, codecs, invalidation helpers, transport aggregation,
+  batching, framework adapters, or public API. Measured fixtures do not define
+  universal timing, memory, renderer, or application-bundle budgets.
+
+## Task checks
+
+The existing packed-consumer verifier checks package-only Intent discovery/loading,
+installed version, reference resolution, exact archive inventory, and every TypeScript
+example with both supported compilers and Query peers. Its runtime fixtures exercise
+policy identity, snapshot drain and abort, metadata sharing, hydration preparation,
+optimistic overlap, events, owner retirement, and native reactive framework hosts.
+Native maintenance checks separately validate records and detect source changes.
+Fresh-context consumer execution supplies an independent task check; neither native
+bookkeeping nor syntax validation establishes semantic correctness by itself.
+
+## Coverage and batch history
+
+- At source revision `8b2b346ebe98e134de19a9ff5bff91c431fd80c3`, the initial maintenance
+  batch registers the existing root-package skill and its source-backed tasks.
+  It corrects stream policy identity, adopts the public snapshot helper, and adds
+  conditional metadata, cache ownership, hydration, reactive framework, transport,
+  and performance-limit guidance. The migrated purpose receives the approved HTTP/framework scope correction.
+  The full packed-consumer matrix passes with both supported compilers and Query
+  peers. Independent consumer execution verifies numeric stream snapshots, awaited
+  cleanup before dehydration, paired metadata codecs, and sharing policies. Its
+  fresh-cache experiment adds a native imperative option-installation caveat to
+  the HTTP reference; all ten TypeScript examples remain unchanged.
+  Source coverage includes README and all Markdown/MDX site pages so the final
+  documentation reconciliation requires a native review. Check outcomes and
+  justified source reviews are recorded before handoff.
+
+## Remaining work
+
+Following approved slices reconcile README/site with final behavior, update skill
+version metadata during manual 0.1.0 preparation, and verify the exact candidate
+archive. Their actual source changes require a new native review. Framework SSR/AOT,
+cross-host worker transport, durable event delivery, and future dependency releases
+remain outside the verified integration scope.
+
+The pre-migration description was: “Use effect-api-query to derive TanStack Query
+options and cache keys from Effect RPC or HttpApi contracts. Load when wiring
+createRpcQueryUtils or createHttpApiQueryUtils, choosing query or mutation builders,
+adding pagination or RPC streams, configuring cache identity, handling execution
+failures or cancellation, or integrating the library with React Query or SSR.”
+The approved purpose correction includes the now-verified HTTP views and native
+framework/host branches rather than retaining the old RPC/React emphasis.

+# Defaults, filters, writes, and cache owners
+
+## Register native defaults and filters
+
+Create the QueryClient and utilities once for each owner. Register global defaults,
+then matching prefixes from broad to specific; TanStack merges them in registration
+order, without sorting by specificity. Omit an option to inherit it. Explicit
+`initialData: undefined` overrides an inherited seed, and `staleTime: 0` overrides
+inherited freshness. Put typed retry decisions and selectors in the builder.
+
+```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Effect, Schema } from 'effect'
+import { createRpcQueryUtils } from 'effect-api-query'
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+
+export const users = RpcGroup.make(
+  Rpc.make('users.read', {
+    payload: {
+      id: Schema.FiniteFromString,
+      locale: Schema.String.pipe(Schema.withConstructorDefault(Effect.succeed('en'))),
+    },
+    success: Schema.Struct({ id: Schema.Finite, name: Schema.String, locale: Schema.String }),
+  }),
+)
+
+export function userCache(client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof users>>) {
+  const queryClient = new QueryClient({ defaultOptions: { queries: { retry: false } } })
+  const rpc = createRpcQueryUtils(users, { client, keyPrefix: ['users-app'] })
+  queryClient.setQueryDefaults(rpc.key(), { staleTime: 30_000 })
+  queryClient.setQueryDefaults(rpc.users.key(), { gcTime: 600_000 })
+  const queryPrefix = [...rpc.users.read.key(), 'query'] as const
+  queryClient.setQueryDefaults(queryPrefix, { staleTime: 60_000 })

+    everyLocale: { queryKey: [...queryPrefix, { id: '1' }] as const },
+  }
+}
+```
+
+Here `everyLocale` matches the encoded string ID across locales. The concrete key
+materializes `locale: 'en'` and addresses only that full input. Native partial
+filters must follow the actual canonical encoding, including any custom projection.
+HTTP filters retain `params`, `query`, `headers`, and `payload` labels and default
+lowercase header names. An opaque scalar encoder cannot expose omitted fields to
+partial matching; use a broad prefix or an exact generated key.
+
+Root, branch, leaf, and manually appended operation prefixes support native
+`invalidateQueries`, `cancelQueries`, and other filters. Exact stream keys include
+policy. Only concrete generated query keys carry data/error tags; broad reads
+remain `unknown` until the application establishes their representation. Selection
+changes observer results while the cache keeps full decoded data. Configure hashing
+on QueryClient global or prefix defaults and keep it stable; builders reject
+per-call hashing. Mutation defaults and keys use the separate native mutation cache.
+
+## Coordinate overlapping optimistic writes
+
+Keep this workflow in the application and make every participating write follow it:
+
+1. In `onMutate`, capture the originating owner and reserve this write before an
+   await. Cancel older reconciliation reads before publishing optimistic state.
+2. Snapshot only the affected entities and positions. Preserve unrelated list
+   entries, infinite pages, and `pageParams`; allocate temporary IDs per creation.
+3. Return the original owner's commit, rollback, and settlement actions in mutation
+   context. Check that owner after every await and before any cache side effect.
+4. On success, replace only this write's optimistic value and seed exact generated
+   detail keys with the response's locale and other identity fields.
+5. On failure, remove this write's temporary entry or restore its removed entity
+   beside surviving original neighbors. A whole stale-snapshot rollback can erase
+   another write. Coordinate repeated deletions of the same entity explicitly.
+6. Reconcile when the final overlapping write settles. Each new write cancels an
+   earlier reconciliation before its optimistic update.
+
+An observer's option update can replace pending callbacks or a not-yet-started
+mutation function. Context preserves originating actions; remount consumers at an
+owner handoff. Cache rollback cannot undo accepted server work. External writes,
+manual replacement, and server ordering need application conflict policy.
+
+## Refresh from application events
+
+Map authenticated, decoded domain events deliberately to native generated filters.
+If RPC and HTTP share a domain, name both roots. Capture the original owner in one
+scoped consumer; unregister event, Reactivity, and mutation listeners on closure.
+Check that owner before queued invalidation and after awaits.
+
+Defer refresh while participating mutations are pending, retain the invalidation
+intent, and flush it after settlement. A branch refresh may subsume narrower work.
+Effect Reactivity keys need an explicit application mapping; a Query tuple has no
+implied Reactivity subscription. Native batching combines invalidations of the same
+Reactivity key, without guaranteeing one Query refresh across distinct keys.
+
+An accepted monotonic cursor records invalidation intent, not durable delivery or
+successful reads. Replay ordered events with duplicate suppression when supported;
+otherwise refresh authoritative reads and reset the sequence deliberately. The
+application owns authentication, reconnect, replay storage, epochs, acknowledgements,
+and out-of-order delivery.
+
+## Replace an owner in order
+
+Partition results by safe tenant, user, backend, session, and permission-generation
+identity in `keyPrefix`; keep credentials out of keys. Capture the retiring owner,
+unmount its consumers, mark it inactive, stop new work, cancel queries, and drain
+accepted mutations and local streams before releasing ready-client resources.
+Only then acquire and mount the replacement. Apply this sequence even when semantic
+identity is unchanged. A provider client prop change alone does not replace hook
+ownership. Guard late commit, rollback, and settlement callbacks even after drain.
+
+An accepted command may finish remotely during retirement; completed work persists.
+Use an explicit application command-cancellation operation to stop future domain
+work. Local retirement supplies neither rollback nor remote cancellation acknowledgement.
+A hanging request or finalizer can delay handoff.
+
+For reload persistence, allowlist a validated DTO view, repeat the safe owner tuple
+in its envelope, and include schema/key version busters. Restore only matching
+identities through freshly generated keys; discard foreign or incompatible data
+before writing. Avoid persisting pending optimistic values, arbitrary caches, errors,
+mutations, credentials, or class prototypes. Use paired codecs for rich values.
+
+Explicit disposal should expose storage failures while completing resource cleanup.
+Lifecycle callbacks such as pagehide or HMR must handle a rejected disposal Promise
+so it does not become an unhandled rejection. Preserve the chosen reload-persistence
+policy and ordered cleanup.

+# Native frameworks, transports, and supported hosts
+
+## Rebuild captured options from reactive input
+
+Acquire clients and create utilities during application setup. Supply the native
+framework's Query provider. Builders capture plain input at each call; invoke them
+inside the framework's reactive options computation so changed input produces a
+new key and query function. Mutations receive new variables at execution time.
+
+| Framework | Native options construction                                                       |
+| --------- | --------------------------------------------------------------------------------- |
+| React     | Rebuild the builder result as component input changes; use ordinary Query hooks   |
+| Vue       | `computed(() => rpc.users.read.queryOptions(...))` passed to `useQuery`           |
+| Solid     | `useQuery(() => rpc.users.read.queryOptions(...))`                                |
+| Svelte    | `createQuery(() => rpc.users.read.queryOptions(...))`                             |
+| Angular   | `injectQuery(() => rpc.users.read.queryOptions(...))` inside an injection context |
+
+Apply this pattern to infinite, metadata, accumulated, and live options too. This
+factory constructs utilities once and returns hooks for native component setup:
+
+```ts
+import type { InferDataFromTag, InferErrorFromTag } from '@tanstack/query-core'
+import { useQuery as useSolidQuery } from '@tanstack/solid-query'
+import { useQuery as useVueQuery } from '@tanstack/vue-query'
+import { Schema } from 'effect'
+import { createRpcQueryUtils, skipToken } from 'effect-api-query'
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+import { computed, ref } from 'vue'
+
+export const group = RpcGroup.make(
+  Rpc.make('users.read', {
+    payload: { id: Schema.Int },
+    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+  }),
+)
+
+export function makeUserHooks(client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof group>>) {
+  const rpc = createRpcQueryUtils(group, { client, keyPrefix: ['users-app'] })
+  return {
+    useVueUser() {
+      const id = ref<number | undefined>(1)
+      const options = computed(() =>
+        rpc.users.read.queryOptions({
+          input: id.value === undefined ? skipToken : { id: id.value },
+          select: (user) => user.name,
+        }),
+      )
+      type Key = ReturnType<typeof rpc.users.read.queryKey>
+      const user = useVueQuery<
+        InferDataFromTag<unknown, Key>,
+        InferErrorFromTag<Error, Key>,
+        string
+      >(options)
+      return { id, user }
+    },
+    useSolidUser(id: () => number | undefined) {
+      return useSolidQuery(() => {
+        const value = id()
+        return rpc.users.read.queryOptions({
+          input: value === undefined ? skipToken : { id: value },
+          select: (user) => user.name,
+        })
+      })
+    },
+  }
+}
+```
+
+Vue's explicit hook generics preserve tagged data/error types while avoiding deep
+recursive unwrapping of Effect Causes. Let builders infer their arguments. Vue
+function-valued `enabled` is a zero-argument getter; use a boolean or `() => boolean`,
+instead of Core's `enabled(query)` callback. Solid accepts the Core callback.
+
+The pinned Solid query/infinite overloads require a defined seed or no seed; a
+possibly undefined value or initializer does not match. Vue accepts that initializer.
+Explicit `initialData: undefined` overrides inherited seeds. Angular's skipped query
+keeps optional `data()` even with defined initial data; Svelte preserves defined data
+for that combination. Both accept possibly undefined initializers with optional data.
+
+Compile Svelte with `module: 'ESNext'` and `moduleResolution: 'Bundler'`; NodeNext
+checking exposes an upstream `.svelte` declaration import limitation. Angular results
+are signals such as `data()`; register `provideTanStackQuery(queryClient)` and use an
+injection context. Use native infinite and mutation hooks with the matching builders.
+
+Last-observer removal cancels abort-aware open queries. Keep resources alive until
+local finalizers finish. For an owner change, follow the ordered unmount, drain,
+dispose, and remount procedure in [cache workflows](cache-workflows.md).
+
+## Match the verified versions
+
+The verified coordinated Effect/runtime/testing/platform set is 4.0.0. Strict public
+types are checked with TypeScript 5.9.3 and 7.0.2. Match the native Query wrapper to
+the application's Query Core; choose a compiler supported by framework build tooling.
+
+| Framework | Framework version | Query wrapper                  | Query Core                     |
+| --------- | ----------------- | ------------------------------ | ------------------------------ |
+| Vue       | 3.5.43            | 5.103.1 / 5.104.0              | Matching wrapper               |
+| Solid     | 1.9.15            | 5.103.1 / 5.104.0              | Matching wrapper               |
+| Svelte    | 5.57.1            | 6.2.1 / 6.3.0                  | 5.103.1 / 5.104.0 respectively |
+| Angular   | 22.2.1            | experimental 5.103.1 / 5.104.0 | Matching wrapper               |
+
+Angular core, common, compiler, and platform-browser use one release with RxJS 7.8.2.
+These native integrations have browser-component lifecycle evidence. Framework SSR,
+AOT, worker transport, or arbitrary future releases need separate verification.
+Upgrade a coordinated dependency set against its installed declarations and rerun
+the affected type/runtime/host checks; an upstream fix or broad peer range alone is
+insufficient evidence.
+
+## Keep transport and host ownership explicit
+
+- **HTTP RPC:** acquire a flat client in a live application Scope with matching
+  protocol and serialization, as in [RPC setup](rpc.md).
+- **Shared WebSocket RPC:** concurrent unary and stream requests share the owned
+  connection while retaining independent keys and cancellation. Acquire replacement
+  resources after retiring the prior owner. Reconnect, backoff, authentication, and
+  replay remain application policy. Local cancellation does not prove remote cleanup.
+- **Server-local RPC:** a request-scoped public decoded-message client/server can
+  avoid a network round trip. Server-owned services determine authority; caller
+  services cannot override it. This path skips wire Schema codecs; retain a
+  schema-aware protocol when their validation or effects matter.
+- **Browser/dedicated worker:** each host owns its ready clients, runtime, Scope,
+  and QueryClient. Worker-hosted operations do not establish cross-host `postMessage`
+  transport, service/shared workers, authentication, or cache synchronization.
+  Await cleanup before terminating a worker.
+- **External OpenAPI HTTP:** `openapi-fetch` 0.17.0 with `openapi-typescript` 7.13.0
+  consumes encoded DTOs generated from native `OpenApi.fromApi`. It calls HTTP
+  independently and cannot replace the ready Effect HttpApiClient in the factory.
+  Multipart needs explicit FormData serialization. Raw SSE bytes provide neither
+  event parsing nor Schema decoding or reserved-failure handling.
+
+With Effect 4.0.0, native-default buffer-16 cancellation preserves an active unary
+on a shared WebSocket even with the queue full. An overflowing buffer of size one
+can stall other calls. A client chunk Schema failure can also fail unrelated calls;
+larger buffers do not isolate decoding failures. Keep streaming schemas compatible.
+
+Single-element arrays in GET and form-urlencoded payloads can fail native server
+decoding. Array query parameters and JSON array responses retain their representation.
+The factories preserve the ready client's actual execution contract; they supply
+no transport batching, platform services, or framework providers. Error guards use
+same-realm `instanceof`; transfer safe error DTOs deliberately across realms.

+# Capture, hydrate, and dispose request data
+
+## Capture an open stream
+
+Use a fresh request-owned QueryClient and keep its ready clients, runner, and Scope
+alive until every capture and preparation settles. `queryClient.query` waits for
+stream completion. Use `fetchStreamSnapshot` for the first new cache publication or
+normal completion; it cancels that exact query and awaits local iterator cleanup.
+
+```ts
+import { dehydrate } from '@tanstack/query-core'
+import type { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+import { createRpcQueryUtils, fetchStreamSnapshot } from 'effect-api-query'
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+
+export const updates = RpcGroup.make(
+  Rpc.make('updates.watch', {
+    payload: { channel: Schema.String },
+    success: Schema.String,
+    stream: true,
+  }),
+)
+
+export async function captureUpdates(
+  queryClient: QueryClient,
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof updates>>,
+  signal: AbortSignal,
+) {
+  const rpc = createRpcQueryUtils(updates, { client, keyPrefix: ['updates-app'] })
+  const options = rpc.updates.watch.streamedOptions({
+    input: { channel: 'news' },
+    maxChunks: 20,
+    retry: false,
+  })
+  await fetchStreamSnapshot(queryClient, options, { signal, timeoutMs: 5_000 })
+  return dehydrate(queryClient, { shouldDehydrateMutation: () => false })
+}
+```
+
+The same helper accepts RPC or HTTP accumulated/live options. Default `fresh` mode
+starts a new attempt even with initial or cached success. `append` retains existing
+history. A `replace` refetch of previously fetched data publishes only at completion,
+so an indefinite replacement needs completion or timeout. Explicit `mode: 'cached'`
+reuses successful data without starting or cancelling work, and falls back to fresh
+when no successful entry exists. Native `select` and QueryClient defaults apply.
+
+Reserve the exact key exclusively during fresh capture: it must be idle and
+unobserved. Avoid same-key writes, observers, and concurrent fetches until settlement;
+an external manual publication can otherwise look like a stream emission. Other
+keys keep running. Hash through QueryClient defaults; per-call `queryHash` and
+`queryKeyHashFn` are rejected.
+
+Abort and timeout stop the data wait, then cleanup is awaited before resolution or
+rejection. `timeoutMs` does not bound finalization. Local settlement does not await a
+remote cancellation acknowledgement. Dispose client resources after helper settlement.
+
+## Choose a consistent cache representation
+
+Server and browser need equivalent contracts, inputs, safe prefixes, and hashing.
+Use independent QueryClients, clients, runners, and Scopes. Choose `staleTime` to
+control the first browser refetch; a new browser stream reconnects independently.
+
+Use JSON-safe success DTOs in both caches, or encode decoded domain values at the
+snapshot boundary and decode them during hydration. `select` changes observer data,
+not the cache. `structuredClone` does not restore class prototypes or supply JSON
+codecs for bigint and bytes. This synchronous paired codec keeps rich values through
+hydration and later contract refetch:
+
+```ts
+import { defaultShouldDehydrateQuery, dehydrate, hydrate } from '@tanstack/query-core'
+import type { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
+
+export class Profile extends Schema.Class<Profile>('Profile')({
+  name: Schema.String,
+  credits: Schema.BigIntFromString,
+  avatar: Schema.Uint8ArrayFromBase64,
+}) {
+  summary() {
+    return `${this.name}: ${this.credits} credits`
+  }
+}
+
+export const snapshotProfile = (queryClient: QueryClient): string =>
+  JSON.stringify(
+    dehydrate(queryClient, {
+      shouldDehydrateMutation: () => false,
+      shouldDehydrateQuery: (query) =>
+        defaultShouldDehydrateQuery(query) && query.queryKey[0] === 'profile',
+      serializeData: Schema.encodeUnknownSync(Profile),
+    }),
+  )
+
+export const hydrateProfile = (queryClient: QueryClient, json: string): void =>
+  hydrate(queryClient, JSON.parse(json), {
+    defaultOptions: { deserializeData: Schema.decodeUnknownSync(Profile) },
+  })
+```
+
+Reserve this recipe's prefix for unary `Profile` data and declare `Profile` as the
+operation success on both sides. The enclosing snapshot must come from the matching
+application encoder. Synchronous callbacks require service-free synchronous codecs.
+
+For effectful or serviceful codecs, run application-owned preparation before native
+dehydration transport or hydration. Await all selected encodings before publishing
+one snapshot. Decode all selected entries before one native `hydrate` call, so one
+failed decode leaves the destination untouched. Never store preparation Effects or
+Promises as query data. Supply codec services through the owning runtime.
+
+Choose codecs for the complete view:
+
+| View                        | Preserve                                                                      |
+| --------------------------- | ----------------------------------------------------------------------------- |
+| Infinite data               | Every `pages` value and `pageParams` representation                           |
+| Accumulated stream          | Ordered decoded values, including distinct `undefined` and `null`             |
+| Live stream                 | Latest decoded value, with top-level `undefined` already normalized to `null` |
+| HTTP decoded header wrapper | Body and decoded headers, reconstructing the wrapper                          |
+| HTTP metadata               | Decoded data/wrapper, status, and approved raw string headers                 |
+
+JSON turns undefined array elements into null; use a tagged codec when accumulated
+history distinguishes them. A header wrapper with an undefined body remains a
+wrapper, so preserve that body separately. Encode all declared success alternatives
+and rich page parameters. The package supplies no codec registry or serializer.
+
+Retain `defaultShouldDehydrateQuery` to omit failed queries. Custom error transfer
+must separately encode `state.error` and `state.fetchFailureReason`; data codecs do
+not sanitize Causes, headers, or those fields. A safe error DTO does not automatically
+reconstruct package error classes. Apply application disclosure rules before transport.
+
+## Drain request work before disposal
+
+Track abortable preparation and snapshot captures in the request owner. On request
+completion or abort, stop accepting work, abort pending preparation/captures, cancel
+queries, and await their settlement and local finalizers before closing clients or
+runtimes. Cancelling QueryClient work alone does not drain codec preparation or
+acknowledge finalization. Clear the request's private cache as part of its lifecycle.
+The browser acquires independent resources after hydration.

+RPC APIs. The repository targets stable Effect 4, whose RPC and HTTP API modules still declare
+unstable APIs.
 
 ## Decision
 
 The first public release targets `effect/rpc` and `effect/http-api` from one exact Effect 4 release.
-Each release declares and tests one exact Effect peer. Internal adapters isolate upstream extraction
-and invocation. Keep the exact pin while the adapters depend on unstable upstream APIs.
-
-Effect diagnostics suppress `unstableApiUsage` in `src/http` and `src/rpc`, the transport tests,
-and the compile-time contract fixtures in `tests/types`. These areas deliberately use the exact
-peer's unstable modules. Directory and filename patterns cover new adapter and contract files;
-mixed-purpose examples retain explicit file exceptions. The warning remains enabled in `src/core`,
-scripts, and all other files. All other diagnostics remain enforced.
-
-The exception suppresses every unstable API warning in the matching files, including warnings
-from newly introduced APIs. Review those dependencies when adding an API or upgrading Effect,
-and run the type, runtime, and packed-consumer checks on each upgrade.

 ## Consequences
 
+Review upstream dependencies when adding an API or upgrading Effect. Each coordinated Effect
+upgrade requires published-type, runtime, and packed-consumer checks.

 Before `1.0`, breaking public changes raise the minor version and compatible changes raise the
 patch. An Effect-only upgrade may raise the patch when the public API remains compatible. The

+## 0.1.0
+
+Initial release of typed TanStack Query utilities derived from Effect RPC and HttpApi contracts.
+
+- Build query, mutation, and infinite-query options for unary RPCs and supported buffered HTTP endpoints without multipart. Factories consume application-owned ready clients and preserve typed keys, constructor-aware RPC inputs, decoded HTTP request parts, and custom key encoders.
+- Consume RPC streams and supported HTTP SSE endpoints as ordered accumulated histories or latest-value live queries. Accumulated keys include retention and refetch policy; HTTP stream keys also include decoder policy.
+- Normalize successful buffered query values and live emissions from `undefined` to `null`. Accumulated elements and mutation results preserve their decoded values.
+- Respect QueryClient global and prefix hashing defaults while keeping canonical keys immutable and broad prefixes available for invalidation.
+- Preserve complete Effect Causes in RPC and HTTP execution errors, including independent stream interruption. Queries forward cancellation and release local stream resources.
+- Read buffered HTTP data with immutable status/header metadata through a separate cached view, and send explicit `FormData` through buffered multipart mutations.
+- Capture successful data from open streams with `fetchStreamSnapshot`, awaiting its local iterator cleanup before returning.
+- Include application recipes for paired hydration codecs, SSR preparation, retries, optimistic writes, owner changes, persistence, and event-driven refresh; native framework and browser/worker consumers verify their documented integration boundaries.
+- Ship one side-effect-free ES2022 ESM root with declarations, source maps, ISC licensing, and a package-discoverable TanStack Intent usage skill.
+
+The exact Effect peer is **4.0.0**. Coordinate Effect runtime, testing, and platform versions when upgrading; RPC and HTTP API modules remain unstable. Query Core peers are **`>=5.103.1 <6`**, tested at **5.103.1** and **5.104.0** with strict TypeScript **5.9.3** and **7.0.2**. Framework, host, HTTP, and transport limits are documented in the [compatibility reference](https://ueberbrot.github.io/effect-api-query/reference/compatibility-and-limits/).

-## 0.1.0
-
-Initial release of typed TanStack Query utilities derived from Effect RPC and HttpApi contracts.
-
-- Build query, mutation, and infinite-query options for unary RPCs and supported buffered HTTP endpoints without multipart. Factories consume application-owned ready clients and preserve typed keys, constructor-aware RPC inputs, decoded HTTP request parts, and custom key encoders.
-- Consume RPC streams and supported HTTP SSE endpoints as ordered accumulated histories or latest-value live queries. Accumulated keys include retention and refetch policy; HTTP stream keys also include decoder policy.
-- Normalize successful buffered query values and live emissions from `undefined` to `null`. Accumulated elements and mutation results preserve their decoded values.
-- Respect QueryClient global and prefix hashing defaults while keeping canonical keys immutable and broad prefixes available for invalidation.
-- Preserve complete Effect Causes in RPC and HTTP execution errors, including independent stream interruption. Queries forward cancellation and release local stream resources.
-- Read buffered HTTP data with immutable status/header metadata through a separate cached view, and send explicit `FormData` through buffered multipart mutations.
-- Capture successful data from open streams with `fetchStreamSnapshot`, awaiting its local iterator cleanup before returning.
-- Include application recipes for paired hydration codecs, SSR preparation, retries, optimistic writes, owner changes, persistence, and event-driven refresh; native framework and browser/worker consumers verify their documented integration boundaries.
-- Ship one side-effect-free ES2022 ESM root with declarations, source maps, ISC licensing, and a package-discoverable TanStack Intent usage skill.

-The exact Effect peer is **4.0.0**. Coordinate Effect runtime, testing, and platform versions when upgrading; RPC and HTTP API modules remain unstable. Query Core peers are **`>=5.103.1 <6`**, tested at **5.103.1** and **5.104.0** with strict TypeScript **5.9.3** and **7.0.2**.

-## Decisions and boundaries
-
-- Preserve one library skill rather than introducing prerequisite or framework
-  skills for existing branches. Conditional references avoid loading every workflow.
-- Migrate the original description to purpose, then apply the approved correction
-  for the settled HTTP and framework scope. Keep activation task-oriented and
-  record the verified package version in skill metadata.
-- Keep package-only distribution. Planning records and review state remain outside
-  shipped skills and the package allowlist.
-- Keep scoped native skill validation in the existing uncached task and CI path.
-  Record revision-bound source and planning reviews with actual task evidence.
-  Repository-wide native review also selects unrelated local authoring skills,
-  so it cannot serve as this library skill's CI gate. Preserve those unresolved
-  items and the existing pinned installer semantics.
-- Keep the audited coordinated Effect 4.0.0 set. The buffer-16 cancellation control
-  covers one acknowledged 16-value chunk, zero consumption, immediate request-Scope
-  closure, and concurrent unary success. Larger chunks and unfinished offers remain
-  unverified; buffer-one overflow, chunk Schema isolation, and single-element
-  GET/form payload-array limitations remain explicit.
-- Add no clients, providers, codecs, invalidation helpers, transport aggregation,
-  batching, framework adapters, or public API. Measured fixtures do not define
-  universal timing, memory, renderer, or application-bundle budgets.
-
-## Task checks
-
-The existing packed-consumer verifier checks package-only Intent discovery/loading,
-installed version, reference resolution, exact archive inventory, and every TypeScript
-example with both supported compilers and Query peers. Its runtime fixtures exercise
-policy identity, snapshot drain and abort, metadata sharing, hydration preparation,
-optimistic overlap, events, owner retirement, and native reactive framework hosts.
-Native maintenance checks separately validate records and detect source changes.
-Fresh-context consumer execution supplies an independent task check; neither native
-bookkeeping nor syntax validation establishes semantic correctness by itself.
-
-## Coverage and batch history
-
-- At source revision `8b2b346ebe98e134de19a9ff5bff91c431fd80c3`, the initial maintenance
-  batch registers the existing root-package skill and its source-backed tasks.
-  It corrects stream policy identity, adopts the public snapshot helper, and adds
-  conditional metadata, cache ownership, hydration, reactive framework, transport,
-  and performance-limit guidance. The migrated purpose receives the approved HTTP/framework scope correction.
-  The full packed-consumer matrix passes with both supported compilers and Query
-  peers. Independent consumer execution verifies numeric stream snapshots, awaited
-  cleanup before dehydration, paired metadata codecs, and sharing policies. Its
-  fresh-cache experiment adds a native imperative option-installation caveat to
-  the HTTP reference; all ten TypeScript examples remain unchanged.
-  Source coverage includes README and all Markdown/MDX site pages so the final
-  documentation reconciliation requires a native review. Check outcomes and
-  justified source reviews are recorded before handoff.
-  Independent Standards review narrows the buffer-16 statement to the acknowledged
-  16-value chunk, zero-consumption, immediate request-Scope closure control with
-  concurrent unary success. Larger chunks and unfinished offers remain unverified;
-  the reproduced overflowing buffer-one and chunk-Schema limits remain explicit.
-
-- At source revision `a55b931a093f380b79b8d3d714cb3ec640a1411c`, human documentation
-  reconciliation aligns capability summaries, captured inputs, metadata policy
-  installation, local cleanup, exact tested versions, and application ownership
-  with the maintained skill. Earlier-build migration language is removed because
-  the package is unreleased. The exact-peer ADR retains its architectural rationale
-  and upgrade validation responsibility while configuration mechanics are removed.
-  Existing recipes and skill examples retain their behavior and source mappings.
-  Documentation snippets, Astro diagnostics, scoped skill validation, and the
-  fresh packed-consumer matrix pass. The worktree's Starlight build cannot resolve
-  virtual style metadata through linked dependencies; canonical build and browser
-  checks remain required before integration.
-  Standards review corrects the Vite example summary to its actual query
-  cancellation, accepted-command drain, cache clearing, and client disposal.
-  Independent iterator cleanup remains an application-owned completion signal.
-

-  preparation sets the root and maintained skill records to 0.1.0 and registers
-  the initial changelog as an authoritative source. Release notes describe the
-  current contract, exact Effect peer, tested Query Core versions, normalized
-  query data, and cache identity. Package-only distribution, existing references,
-  and application ownership remain unchanged. The fresh native build, scoped
-  skill validation, installed version, examples, and both compiler/peer matrices
-  pass for the selected archive. Owned native source reviews are recorded;
-  complete integration acceptance remains open.
-
-## Remaining work
-
-Verify the selected 0.1.0 archive through final integration acceptance. Subsequent
-source or guidance changes require a new native review. Framework SSR/AOT,
-cross-host worker transport, durable event delivery, and future dependency releases
-remain outside the verified integration scope.
-
-The pre-migration description was: “Use effect-api-query to derive TanStack Query
-options and cache keys from Effect RPC or HttpApi contracts. Load when wiring
-createRpcQueryUtils or createHttpApiQueryUtils, choosing query or mutation builders,
-adding pagination or RPC streams, configuring cache identity, handling execution
-failures or cancellation, or integrating the library with React Query or SSR.”
-The approved purpose correction includes the now-verified HTTP views and native
-framework/host branches rather than retaining the old RPC/React emphasis.
+The package derives TanStack Query utilities from Effect RPC and HTTP contracts
+and ready clients. Applications own transport, authentication, runtime, Scope,
+cache ownership, and serialization policy.
+
+## Structure
+
+One automatically discoverable `effect-api-query` skill covers the existing
+library. Its entry point holds shared rules and routes conditional tasks to six
+references:
+
+| Reference            | Tasks                                                            |
+| -------------------- | ---------------------------------------------------------------- |
+| RPC                  | Payload construction, canonical identity, ready-client lifetime  |
+| HTTP                 | Decoded requests, SSE, multipart mutations, metadata             |
+| Query patterns       | Skipping, pagination, accumulated and live views                 |
+| Cache workflows      | Defaults, filters, overlapping writes, events, owner replacement |
+| Hydration and SSR    | Snapshots, paired view codecs, preparation and cleanup           |
+| Frameworks and hosts | Reactive accessors, transports, version and host limits          |
+
+Consumers load the guidance from their installed package without repository-local
+authoring skills. Planning records remain outside the shipped package.
+
+## Sources and boundaries
+
+The [domain map](domain_map.yaml) owns task coverage and failure modes. The
+[skill tree](skill_tree.yaml) owns skill paths and source mappings. Public
+declarations and runtime own API facts; application modules and guides own cache
+and lifecycle recipes.
+
+Keep guidance within existing library behavior. Preserve application ownership
+and qualify support through [frameworks and hosts](../skills/effect-api-query/references/frameworks-and-hosts.md).
+Measurements describe their fixtures; they do not establish universal budgets.
+
+## Validation
+
+Native Intent maintenance detects source changes and records justified outcomes
+for the owned skill and planning records. Leave unrelated skills unresolved and
+run the uncached scoped `skills-check` task.
+
+The packed-consumer verifier checks installed version and peers, package-only
+discovery, reference resolution, archive inventory, and skill examples with both
+supported compilers and Query peers. Runtime fixtures cover cached views,
+cancellation and preparation, hydration, cache ownership, and reactive framework
+hosts. Independent consumer execution checks that the guidance supports actual
+tasks.

+title: Angular Query
+description: Rebuild generated options from Angular signals and keep client lifetime in the application.
+---
+
+Pass generated options through the framework's reactive accessor. Each builder captures its
+plain input when called, so create the options inside that accessor whenever the input can change.
+The same rule applies to RPC and HTTP queries, metadata views, accumulated streams, and live queries.
+
+The examples target Angular 22.2.1 with Angular Query experimental 5.104.0 and Query Core 5.104.0.
+
+Keep captured values unchanged while their options can execute. See
+[Data Normalization](/effect-api-query/concepts/data-normalization/#keep-captured-inputs-unchanged)
+for the distinction between immutable keys and caller-owned input.
+
+## Create queries in an injection context
+
+Register `provideTanStackQuery(queryClient)` in your application providers. Construct queries
+inside an Angular injection context and read the signal inside the accessor passed to `injectQuery`.
+The ready client below is acquired and disposed by the application. Keep its `Scope` and any
+serviceful runner alive while queries use them:
+
+```ts
+import { Component, signal } from '@angular/core'
+import { injectQuery } from '@tanstack/angular-query-experimental'
+import { Schema } from 'effect'
+import { createRpcQueryUtils } from 'effect-api-query'
+import { Rpc, RpcGroup, type RpcClient } from 'effect/rpc'
+
+const group = RpcGroup.make(
+  Rpc.make('users.read', {
+    payload: { id: Schema.Int },
+    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+  }),
+)
+declare const client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof group>>
+const rpc = createRpcQueryUtils(group, { client, keyPrefix: ['current-owner'] })
+
+@Component({
+  selector: 'user-details',
+  standalone: true,
+  template: '<button (click)="next()">Next user</button><p>{{ user.data() }}</p>',
+})
+class UserDetails {
+  readonly id = signal(1)
+  readonly user = injectQuery(() =>
+    rpc.users.read.queryOptions({
+      input: { id: this.id() },
+      select: (user) => user.name,
+    }),
+  )
+
+  next() {
+    this.id.update((id) => id + 1)
+  }
+}
+```
+
+Use `injectInfiniteQuery` with `infiniteOptions` and `injectMutation` with `mutationOptions`.
+Supply each mutation's input through its execution variables. Angular query results expose
+signals such as `data()`, `error()`, and `fetchStatus()`.
+
+Use the same accessor for `streamedOptions`, `liveOptions`, and HTTP `metadataOptions`. These
+provide accumulated history, the latest emission, and decoded data with status/header snapshots,
+respectively.
+
+## Choose native options carefully
+
+Angular's defined-data overload accepts a query function rather than `skipToken`. A skipped query
+therefore retains `undefined` in its `data()` type even when it has defined `initialData`. An
+initial-data function that may return `undefined` also produces optional result data.
+
+## Own the lifecycle
+
+Open streams expose their first value while fetching continues. Changing a generated query's key
+replaces the observer's active query. Destroying an Angular component removes its observers;
+the last observer of an abort-aware open stream triggers
+cancellation. Keep the ready client and runtime alive until local stream finalizers finish.
+Other observers of the same query retain their subscription.
+
+For an owner change, unmount the old tree, cancel and clear its QueryClient, await local cleanup,
+then dispose its client resources. Mount the new tree with independently owned resources and a
+safe key prefix. See [Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/) and
+[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/).
+
+Match Angular Query to the application's Query Core and use a compiler supported by its build
+tooling. Angular core, common, compiler, and platform-browser should share one release.
+Server rendering and hydration remain application integrations.

+title: Solid Query
+description: Rebuild generated options with a Solid accessor and keep client resources alive.
+---
+
+Pass generated options from either factory to Solid Query's native hooks. Configure
+`QueryClientProvider` and acquire the ready client before creating the utilities. Keep its `Scope`
+and any serviceful runner alive while queries use them.
+
+The examples target Solid 1.9.15 with Solid Query 5.104.0 and Query Core 5.104.0.
+
+Match the native Query wrapper to the application's Query Core and use a compiler supported by
+the framework's tooling. See the
+[compatibility reference](/effect-api-query/reference/compatibility-and-limits/) for adapter capabilities.
+
+## Rebuild options when input changes
+
+Builders capture plain input when called. Build options inside Solid's options accessor so a
+changed input produces a new key and query function. Passing a builder's result once leaves the
+query attached to the original input.
+
+Keep captured values unchanged while their options can execute. See
+[Data Normalization](/effect-api-query/concepts/data-normalization/#keep-captured-inputs-unchanged)
+for the distinction between immutable keys and caller-owned input.
+
+In a Solid component, pass the builder call as an accessor:
+
+```ts
+import { useQuery } from '@tanstack/solid-query'
+import { skipToken } from 'effect-api-query'
+import { createSignal } from 'solid-js'
+
+import { rpc } from './queries.ts'
+
+const [userId] = createSignal<number | undefined>(1)
+const user = useQuery(() => {
+  const id = userId()
+  return rpc.users.read.queryOptions({
+    input: id === undefined ? skipToken : { id },
+    select: (value) => value.name,
+  })
+})
+```
+
+Read the selected value from `user.data`. Apply the same accessor pattern to `infiniteOptions`,
+`streamedOptions`, `liveOptions`, and `metadataOptions` when their input changes. Use
+`useMutation(() => rpc.users.write.mutationOptions())` for writes, supplying each execution's
+input through `mutate(variables)`. Read reactive mutation settings inside the accessor.
+
+## Choose native options carefully
+
+Solid accepts Core's `enabled(query)` callback. Solid Query 5.104.0 query and infinite-query
+overloads accept defined initial data or absent initial data. A value or initializer that may
+return `undefined` does not match those overloads. Omit `initialData` or supply a defined seed.
+An explicit `initialData: undefined` overrides inherited QueryClient initial data.
+
+## Own streams and disposal
+
+Open streams expose their first value while fetching continues. Changing reactive input replaces
+the query; when its last observer leaves, query cancellation closes the stream iterator. Solid
+owner disposal also releases observed streams. Keep client resources alive until these queries
+finish cancelling, then clear the owned QueryClient and close the client scope. Transport
+interruption depends on the ready client.
+
+Use `streamedOptions` for an accumulated history and `liveOptions` for its latest emission. HTTP
+`metadataOptions` retains decoded data, response status, and header snapshots in a separate cache
+entry. Follow [client lifecycle](/effect-api-query/concepts/client-lifecycle/) and
+[cancellation](/effect-api-query/guides/cancellation/) when disposing the cache owner.

-description: Rebuild generated options when reactive inputs change and keep client lifetime in the application.
----
-
-Pass generated options through the framework's reactive accessor. Each builder captures its
-plain input when called, so create the options inside that accessor whenever the input can change.
-The same rule applies to RPC and HTTP queries, metadata views, accumulated streams, and live queries.
-
-The examples target Svelte 5.57.1 with Svelte Query 6.3.0 and Angular 22.2.1 with Angular Query
-experimental 5.104.0, both using Query Core 5.104.0.
-
-Keep captured values unchanged while their options can execute. See
-[Data Normalization](/effect-api-query/concepts/data-normalization/#keep-captured-inputs-unchanged)
-for the distinction between immutable keys and caller-owned input.
-
-## Svelte
-
-Create the utility tree in your application module from an acquired ready client. Provide a
-QueryClient through Svelte Query's `QueryClientProvider`, then read reactive inputs inside the
-accessor passed to `createQuery`:
-
-```svelte
-<script lang="ts">
-  import { createQuery } from '@tanstack/svelte-query'
-  import { rpc } from './api'
-
-  let id = $state(1)
-  const user = createQuery(() =>
-    rpc.users.read.queryOptions({
-      input: { id },
-      select: (user) => user.name,
-    }),
-  )
-</script>
-
-<button onclick={() => id += 1}>Next user</button>
-<p>{user.data}</p>
-```
-
-Use `createInfiniteQuery(() => rpc.users.list.infiniteOptions(...))` for pagination and
-`createMutation(() => rpc.users.write.mutationOptions(...))` for writes. A mutation's variables
-provide the input for each execution. Mutation options can be static when their callbacks and
-other settings do not depend on reactive state.
-
-Compile the Svelte application with `module: "ESNext"` and `moduleResolution: "Bundler"`.
-Svelte Query 6 requires this resolution for its emitted `.svelte`
-declarations; strict NodeNext declaration checking reports an upstream `Box` import error.
-
-## Angular
-
-Register `provideTanStackQuery(queryClient)` in your application providers. Construct queries
-inside an Angular injection context and read the signal inside the accessor passed to `injectQuery`.
-The ready client below is acquired and disposed by the application:
-
-```ts
-import { Component, signal } from '@angular/core'
-import { injectQuery } from '@tanstack/angular-query-experimental'
-import { Schema } from 'effect'
-import { createRpcQueryUtils } from 'effect-api-query'
-import { Rpc, RpcGroup, type RpcClient } from 'effect/rpc'
-
-const group = RpcGroup.make(
-  Rpc.make('users.read', {
-    payload: { id: Schema.Int },
-    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
-  }),
-)
-declare const client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof group>>
-const rpc = createRpcQueryUtils(group, { client, keyPrefix: ['current-owner'] })
-
-@Component({
-  selector: 'user-details',
-  standalone: true,
-  template: '<button (click)="next()">Next user</button><p>{{ user.data() }}</p>',
-})
-class UserDetails {
-  readonly id = signal(1)
-  readonly user = injectQuery(() =>
-    rpc.users.read.queryOptions({
-      input: { id: this.id() },
-      select: (user) => user.name,
-    }),
-  )
-
-  next() {
-    this.id.update((id) => id + 1)
-  }
-}
-```
-
-Use `injectInfiniteQuery` and `injectMutation` with the corresponding builders. Angular query
-results expose signals such as `data()`, `error()`, and `fetchStatus()`.
-
-Angular's defined-data overload accepts a query function rather than `skipToken`. A skipped query
-therefore retains `undefined` in its `data()` type even when it has defined `initialData`. Svelte
-preserves the defined-data type for that combination. Both frameworks accept initial-data functions
-that may return `undefined`, with optional result data.
-
-## Own the lifecycle
-
-Changing a generated query's key replaces the observer's active query. Unmounting a Svelte
-component or destroying an Angular component removes its observers; the last observer of an
-abort-aware open stream triggers cancellation. Keep the ready client and runtime alive until
-local stream finalizers finish. Other observers of the same query retain their subscription.
-
-For an owner change, unmount the old tree, cancel and clear its QueryClient, await local cleanup,
-then dispose its client resources. Mount the new tree with independently owned resources and a
-safe key prefix. See [Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/) and
-[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/).
-
-Match each framework Query wrapper to the application's Query Core and use a compiler supported
-by its build tooling. Angular core, common, compiler, and platform-browser should share one
-release. Framework server rendering and hydration remain application integrations.

+plain input when called, so create the options inside that accessor whenever the input can change.
+The same rule applies to RPC and HTTP queries, metadata views, accumulated streams, and live queries.
+
+The examples target Svelte 5.57.1 with Svelte Query 6.3.0 and Query Core 5.104.0.
+
+Keep captured values unchanged while their options can execute. See
+[Data Normalization](/effect-api-query/concepts/data-normalization/#keep-captured-inputs-unchanged)
+for the distinction between immutable keys and caller-owned input.
+
+## Create native queries
+
+Create the utility tree in your application module from an acquired ready client. Provide a
+QueryClient through Svelte Query's `QueryClientProvider`, then read reactive inputs inside the
+accessor passed to `createQuery`. Keep the client's `Scope` and any serviceful runner alive while
+queries use them:
+
+```svelte
+<script lang="ts">
+  import { createQuery } from '@tanstack/svelte-query'
+  import { rpc } from './api'
+
+  let id = $state(1)
+  const user = createQuery(() =>
+    rpc.users.read.queryOptions({
+      input: { id },
+      select: (user) => user.name,
+    }),
+  )
+</script>
+
+<button onclick={() => id += 1}>Next user</button>
+<p>{user.data}</p>
+```
+
+Use `createInfiniteQuery(() => rpc.users.list.infiniteOptions(...))` for pagination and
+`createMutation(() => rpc.users.write.mutationOptions(...))` for writes. A mutation's variables
+provide the input for each execution. Mutation options can be static when their callbacks and
+other settings do not depend on reactive state.
+
+Use the same accessor for `streamedOptions`, `liveOptions`, and HTTP `metadataOptions`. These
+provide accumulated history, the latest emission, and decoded data with status/header snapshots,
+respectively.
+
+## Choose native options carefully
+
+A skipped query retains the defined-data type when it has defined `initialData`. An initial-data
+function that may return `undefined` produces optional result data.
+
+Compile the Svelte application with `module: "ESNext"` and `moduleResolution: "Bundler"`.
+Svelte Query 6 requires this resolution for its emitted `.svelte` declarations; strict NodeNext
+declaration checking reports an upstream `Box` import error.
+
+## Own the lifecycle
+
+Open streams expose their first value while fetching continues. Changing a generated query's key
+replaces the observer's active query. Unmounting a Svelte component removes its observers;
+the last observer of an abort-aware open stream triggers
+cancellation. Keep the ready client and runtime alive until local stream finalizers finish.
+Other observers of the same query retain their subscription.
+
+For an owner change, unmount the old tree, cancel and clear its QueryClient, await local cleanup,
+then dispose its client resources. Mount the new tree with independently owned resources and a
+safe key prefix. See [Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/) and
+[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/).
+
+Match Svelte Query to the application's Query Core and use a compiler supported by its build
+tooling. Server rendering and hydration remain application integrations.

-title: Vue and Solid Query
-description: Rebuild generated options from reactive input and keep client resources alive.
----
-
-Pass generated options from either factory to the framework's native Query hooks. Configure
-`VueQueryPlugin` in Vue or `QueryClientProvider` in Solid, and acquire the ready client before
-creating the utilities. Keep its `Scope` and any serviceful runner alive while queries use them.
-
-The examples target Vue 3.5.43 with Vue Query 5.104.0 and Solid 1.9.15 with Solid Query 5.104.0.
-Both use Query Core 5.104.0.
-
-Match the native Query wrapper to the application's Query Core and use a compiler supported by
-the framework's tooling. See the
-[compatibility reference](/effect-api-query/reference/compatibility-and-limits/) for adapter capabilities.
-
-## Rebuild options when input changes
-
-Builders capture plain input when called. Build options inside Vue `computed` or Solid's options
-accessor so a changed input produces a new key and query function. Passing a builder's result
-once leaves the query attached to the original input.
-
-Keep captured values unchanged while their options can execute. See
-[Data Normalization](/effect-api-query/concepts/data-normalization/#keep-captured-inputs-unchanged)
-for the distinction between immutable keys and caller-owned input.
-
-In Vue component setup, use a computed options object. This example assumes `rpc.users.read`
-returns a user with a `name`:
-
-```ts
-import type { InferDataFromTag, InferErrorFromTag } from '@tanstack/query-core'
-import { useQuery } from '@tanstack/vue-query'
-import { skipToken } from 'effect-api-query'
-import { computed, ref } from 'vue'
-
-import { rpc } from './queries.ts'
-
-const userId = ref<number | undefined>(1)
-const options = computed(() =>
-  rpc.users.read.queryOptions({
-    input: userId.value === undefined ? skipToken : { id: userId.value },
-    select: (user) => user.name,
-  }),
-)
-type UserKey = ReturnType<typeof rpc.users.read.queryKey>
-const user = useQuery<
-  InferDataFromTag<unknown, UserKey>,
-  InferErrorFromTag<Error, UserKey>,
-  string
->(options)
-```
-
-Read the selected value from `user.data.value`. The explicit native hook generics preserve the
-data and error carried by the concrete generated key while bounding Vue's recursive ref unwrapping.
-Automatic inference can otherwise exceed TypeScript's instantiation depth when it unwraps an
-Effect `Cause` through a tagged key. Let the builder infer its arguments; put these type arguments
-on the Vue hook.
-
-In a Solid component, pass the builder call as an accessor:
-
-```ts
-import { useQuery } from '@tanstack/solid-query'
-import { skipToken } from 'effect-api-query'
-import { createSignal } from 'solid-js'
-
-import { rpc } from './queries.ts'
-
-const [userId] = createSignal<number | undefined>(1)
-const user = useQuery(() => {
-  const id = userId()
-  return rpc.users.read.queryOptions({
-    input: id === undefined ? skipToken : { id },
-    select: (value) => value.name,
-  })
-})
-```
-
-Read the selected value from `user.data`. Apply the same computed/accessor pattern to
-`infiniteOptions`, `streamedOptions`, `liveOptions`, and `metadataOptions` when their input changes.
-
-Pass `rpc.users.write.mutationOptions()` to Vue's `useMutation`, or use
-`useMutation(() => rpc.users.write.mutationOptions())` in Solid. Supply each execution's input
-through `mutate(variables)`; use Vue `computed` or a Solid accessor when mutation settings depend
-on reactive state.
-
-## Choose native options carefully
-
-Vue evaluates a function-valued `enabled` as a getter with no arguments. Use a boolean inside
-computed options, or a zero-argument getter returning a boolean. A Core `enabled(query)` callback
-cannot be passed directly to Vue. Solid accepts the native Core callback.
-
-Solid Query 5.104.0 query and infinite-query overloads accept defined initial data or absent initial
-data. A value or initializer that may return `undefined` does not match those overloads. Omit
-`initialData` or supply a defined seed. Vue accepts a possibly undefined initializer. An explicit
-`initialData: undefined` still overrides inherited QueryClient initial data in both integrations.
-
-## Own streams and disposal
-
-Open streams expose their first value while fetching continues. Changing reactive input replaces
-the query; when its last observer leaves, query cancellation closes the stream iterator. Component
-unmount or Solid owner disposal also releases observed streams. Keep client resources alive until
-these queries finish cancelling, then clear the owned QueryClient and close the client scope.
-Transport interruption depends on the ready client.
-
-Use `streamedOptions` for an accumulated history and `liveOptions` for its latest emission. HTTP
-`metadataOptions` retains decoded data, response status, and header snapshots in a separate cache
-entry. Follow [client lifecycle](/effect-api-query/concepts/client-lifecycle/) and
-[cancellation](/effect-api-query/guides/cancellation/) when disposing the cache owner.

 ### Compare HTTP and RPC
 
-The HTTP panel uses `createHttpApiQueryUtils` from `effect-api-query`; the RPC panels
-use `createRpcQueryUtils` from the same package root. The application owns both ready clients,
-their runners, and the QueryClient. During disposal, it awaits query cancellation, clears the
-cache, drains accepted commands and mutations, and then disposes the HTTP runtime and RPC client.
-Query cancellation can settle before iterator cleanup. See
-[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/#stream-creation-and-consumption)
-for a separate stream-completion signal, and
-[Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/) for persistence and replacement.
-
-Use the HTTP directory to read users, load another page, and create or delete a user. Each write
-explicitly invalidates both generated user prefixes, so the RPC directory reflects HTTP writes
-and the HTTP directory reflects RPC writes. The two adapters retain separate cache keys.
-Choose **Reset directory** to restore the deterministic shared data.
-
-The HTTP user selector passes `skipToken` until a user is selected. HTTP request inputs use
-structured decoded parts such as `params`, `query`, and `payload`; RPC inputs retain their
-payload-constructor defaults. Deleting a user demonstrates an HTTP no-content mutation whose
-result remains `undefined`.
-
-Trigger the HTTP failure to inspect `EffectHttpApiQueryError` and its preserved `Cause`.
-The package adds declaration identifiers to error metadata; upstream Causes can still contain
-request, response, or schema issue values.
-
-Choose **Start slow HTTP query**, wait for **HTTP: Ready to cancel**, then choose
-**Cancel HTTP query**. After the HTTP request aborts, the example observes server interruption for
-that operation. Each panel owns a distinct operation ID, so cancelling an RPC query leaves a
-concurrent HTTP query running. This cancels observation and work in this handler; it does not

-First [install the package](/effect-api-query/getting-started/installation/). Use a server at
-`http://localhost:3000` that implements the declaration below and has an existing user with ID `1`.
-Change the base URL to your server. For browser requests, configure the server's CORS policy to
-allow the application's origin.
-For complete HTTP handlers and applications, [run the examples](/effect-api-query/examples/).
+Import `createHttpApiQueryUtils` from `effect-api-query` and `MutationObserver` from
+`@tanstack/query-core`. The [complete typed recipe](https://github.com/ueberBrot/effect-api-query/blob/main/tests/types/docs-http-quick-start.ts)
+contains the API and runtime setup; the [application examples](/effect-api-query/examples/)
+contain runnable clients and handlers.
 
-## Declare, connect, and call
+## Create the utilities
 
-Save this as `http-client.ts` in your application. Share the HttpApi declaration with your server;
-keep the runtime, client, and `QueryClient` in the application that manages their lifetime.
+In the application client module, after acquiring the client:
 
 ```ts
-import { MutationObserver, QueryClient } from '@tanstack/query-core'
-import { Effect, ManagedRuntime, Schema } from 'effect'
-import { createHttpApiQueryUtils } from 'effect-api-query'
-import { FetchHttpClient } from 'effect/http'
-import { HttpApi, HttpApiClient, HttpApiEndpoint, HttpApiGroup } from 'effect/http-api'
-
-const User = Schema.Struct({ id: Schema.Int, name: Schema.String })
-const usersApi = HttpApi.make('users-api').add(

-    HttpApiEndpoint.get('get', '/users/:id', {
-      params: { id: Schema.Int },
-      query: {
-        locale: Schema.String.pipe(Schema.withConstructorDefault(Effect.succeed('en'))),
-      },
-      success: User,
-    }),
-    HttpApiEndpoint.post('create', '/users', {
-      payload: Schema.Struct({ name: Schema.String }),
-      success: User,
-    }),
-  ),
-)
+const http = createHttpApiQueryUtils(usersApi, {
+  client,
+  keyPrefix: ['users-app'] as const,
+  runPromiseExit: runtime.runPromiseExit,
+})
+```
+
+Use the application's signal-aware runner when client execution needs services. Keep its
+runtime and client resources alive while queries and mutations use them.
 
-const runtime = ManagedRuntime.make(FetchHttpClient.layer)
-const queryClient = new QueryClient()
-
-try {
-  const client = await runtime.runPromise(
-    HttpApiClient.make(usersApi, { baseUrl: 'http://localhost:3000' }),

-
-  const user = await queryClient.query(
-    http.users.get.queryOptions({ input: { params: { id: 1 }, query: { locale: 'en' } } }),
-  )
-  console.log(user.name)
-
-  const createUser = new MutationObserver(queryClient, http.users.create.mutationOptions())
-  const created = await createUser.mutate({ payload: { name: 'Ada' } })

-} finally {
-  try {
-    await queryClient.cancelQueries()
-  } finally {
-    queryClient.clear()
-    await runtime.dispose()
-  }
-}
+## Read a user
+
+In a loader or event handler, use the existing `queryClient`:
+
+```ts
+const user = await queryClient.query(
+  http.users.get.queryOptions({ input: { params: { id: 1 }, query: { locale: 'en' } } }),
+)
 ```
 
-`HttpApiClient.make` creates a ready client using the application's Fetch runtime. Pass that same
-runtime's `runPromiseExit` to the factory so generated calls use that runner and
-forward TanStack's query abort signal.
+HTTP input is the **decoded request**. Supply the endpoint's declared `params`, `query`,
+`headers`, and `payload` containers; the client handles wire encoding. Even if the Schema
+has a constructor default, HTTP builders do not fill it: this request supplies `locale`.
 
-HTTP input is the client's decoded request, with the `params`, `query`, `headers`, and `payload`
-containers declared by the endpoint. Pass `id` as a number; the client handles its wire encoding.
-The POST mutation receives `{ payload: { name: 'Ada' } }`.
+## Execute a write
 
-The request must supply `query: { locale: 'en' }` even though `locale` has a constructor default.
-HTTP builders do not construct RPC payloads or fill constructor defaults.
+Pass the complete decoded request to each mutation execution:
 
-Groups and endpoint identifiers retain their literal names. `users` and `get` produce
-`http.users.get`; a name containing a dot would require bracket access. A group declared with
-`topLevel: true` places its endpoints at the utility root.
+```ts
+const createUser = new MutationObserver(queryClient, http.users.create.mutationOptions())
+const created = await createUser.mutate({ payload: { name: 'Ada' } })
+```
 
-## Choose cache and resource ownership
+After success, refresh the affected reads:
 
-Buffered endpoints without multipart offer both query and mutation builders, regardless of HTTP method.
-Buffered multipart endpoints expose mutations only; see [upload a file](/effect-api-query/guides/http-queries-and-mutations/#upload-a-file).
-Choose a query for an idempotent cached read and a mutation for a command. After a write, invalidate
-the affected keys explicitly. RPC and HTTP have separate key namespaces, so applications that
-expose the same resource through both must invalidate the affected keys in both namespaces.
+```ts
+await queryClient.invalidateQueries({ queryKey: http.users.key() })
+```
 
-The `finally` block cancels queries, clears the cache, and disposes the runtime. In a UI, keep these
-resources alive for the application lifetime and settle pending mutations before disposal. Include
-a safe user or tenant identity in `keyPrefix` whenever client configuration affects returned data.
+Buffered nonmultipart endpoints offer query and mutation builders regardless of HTTP method;
+buffered multipart endpoints offer mutations only. RPC and HTTP use separate namespaces,
+so refresh both deliberately when they represent the same resource.

-Empty completion succeeds with an empty or retained history according to the refetch mode.
-Accumulated arrays preserve decoded `undefined` elements. A declared `WithHeaders` success wraps

-native cache reversion; unsubscribe and cancel active queries before disposing client resources.
-
-`liveKey(input, { sseOptions })` builds the matching exact key. Inputless endpoints accept decoder
-policy alone. Live and accumulated views use separate cache entries; the endpoint's `key()`
-selects both views and every decoder policy. Live queries retain one value and accept no history
-bound or accumulated refetch mode. Input-bearing builders support `skipToken`.
-
-The ready client owns the SSE connection. Handle `Sse.Retry` and its resume cursor through your
-application's retry policy, and supply a declared cursor in `input.headers` when reconnecting.
-New cursor values produce new request identity. Raw bytes, mixed buffered/SSE successes, and

-createUser.mutate({ name: 'Ada' })
+removeUser.mutate({ id: userId })
 ```
 
-Streaming RPCs use the ordinary `useQuery` and `useSuspenseQuery` hooks. Choose whether the cache
-should retain every value or only the latest value:
+Writes do not automatically refresh reads. Choose the affected generated keys in the application.
+
+## Observe a stream

-        }
-      }
-      return Math.min(1_000 * 2 ** attemptIndex, 30_000)
-    },
-  })
+```ts
+if (!isEffectHttpApiQueryError(error) || failureCount >= 2) {
+  return false
+}
+if (Cause.hasDies(error.cause) || Cause.hasInterrupts(error.cause)) {

+      failure.success.reason._tag === 'TransportError'
+    )
+  default:
+    return false
 }
 ```
 
+### Retry delay callback
+
+In the RPC builder's `retryDelay: (attemptIndex, error) => { ... }` body:
+
+```ts
+if (isEffectRpcQueryError(error)) {
+  const failure = Cause.findError(error.cause)
+  if (Result.isSuccess(failure) && failure.success._tag === 'RetryLater') {
+    return Math.min(30_000, Math.max(0, failure.success.retryAfterMs))
+  }
+}
+return Math.min(1_000 * 2 ** attemptIndex, 30_000)
+```
+
+The complete recipe applies the equivalent guarded delay to HTTP. These callbacks are application
+policy for idempotent reads, not a package retry policy.
+
 `Cause.findError` returns a `Result`; after `Result.isSuccess`, `success` retains the declared
 error union. It extracts the first typed failure. Check defects and interruptions first, and
 inspect all `cause.reasons` when several failures are meaningful to your policy. This example

 ## Explore the executable example
 
-The [TanStack Start example](https://github.com/ueberBrot/effect-api-query/tree/main/examples/tanstack-start)
-includes separate RPC and HTTP views to demonstrate both factories. It verifies successful SSR,
-hydration without duplicate reads, cached navigation, pagination, mutations, failures, and
-cancellation. Its `/http-failure` route omits a failed query from dehydration so the browser can
-refetch it.
-See [Executable Examples](/effect-api-query/examples/) for commands and controls.
-
-The example serves RPC at `/rpc` and HTTP at `/api/$`. Both handlers share a demonstration user
-directory, so writes invalidate both sets of query keys. The authorization header contains a
-public demonstration value. Each request owns its cache and connections; disposing one request
-leaves other requests usable.
-
-Server rendering uses request-owned connections built with Effect's public decoded-message client
-and server. They execute the same application state as the network handlers. RPC execution avoids
-HTTP round trips; HTTP loaders call the host's Web handler in process and retain HTTP Schema codecs.
-The browser acquires separate network clients and reconnects both stream views after hydration.
-
-Local RPC middleware captures the request's demonstration authorization value. Per-call headers and
-caller execution services cannot replace that authority. The example defaults that public value to
-`allowed`; replace this demonstration policy with your application's authentication. Decoded-message
-RPC execution bypasses transport Schema codecs. Keep a schema-aware protocol when wire validation

 The package executes calls through the ready client. TanStack provides query cancellation
 signals but has no corresponding mutation signal for the adapter to forward. Configure request
 interception through client middleware and transport construction. Use an explicit domain
 operation when server cancellation must be observable; compensation is a separate operation.

The existing cache-workflows reference already requires actual canonical encoding, originating owner guards, and every returned identity field, including locale. The HTTP reference already excludes metadata for multipart and stream endpoints. No shipped skill claim, task, activation description, prerequisite, version, or source mapping changes. Conditional Queries now names its own ready rpcQuery tree, numeric-id/default-locale user contract, string-channel/string-emission stream prerequisite, and params-only HTTP request prerequisite instead of claiming the quickstart tree supplies them. Existing skill guidance already requires the actual contract input shape and native skipping; no claim or task changes.",

 HTTP uses the same conditional pattern with its decoded request shape. Unary,

-preserves caller options. Inputless operations, key builders, and mutations do

+object and preserve caller options. Inputless operations, key builders, and mutations do
 not accept it. Skipped options cannot execute through manual refetch and are

 same cache entry. Builders reject per-call `queryKeyHashFn` and `queryHash` overrides.
+Configure hashing before cache use and keep it stable while entries remain. A stream execution
+rejects with `UnsupportedQueryHash` if changed hashing conflicts with a matching cached entry.
 
 Key objects cannot contain `__proto__` or `constructor` properties at any depth. This applies to
 prefixes, Schema output, and custom encoder output.

+title: HTTP Metadata
+description: Read decoded HTTP data, response status, and headers in a separate cache view.
+---
+
+Buffered HTTP endpoints with query support expose `metadataOptions`. Use your ready `http` utility
+tree and QueryClient from the [HTTP quick start](/effect-api-query/getting-started/http-quick-start/).
+Here, `users.get` declares `params.id` and `query.locale` and returns a user with `id` and `name`.
+
+## Read status and headers
+
+```ts
+const input = { params: { id: 1 }, query: { locale: 'en' } }
+const metadataOptions = http.users.get.metadataOptions({ input })
+const current = await queryClient.query(metadataOptions)
+console.log(current.data.name, current.status)
+const etag = current.headers['etag']
+```
+
+The cache holds decoded `data`, numeric `status`, and raw string `headers` in a separate view.
+Fetched envelopes and copied headers are immutable. Decoded data keeps its ownership, including
+declared response-header wrappers. Choose safe headers before persistence or hydration.
+Use `metadataOptions.queryKey` or `metadataKey(input)` for exact access; the endpoint's `key()`
+matches ordinary and metadata views.
+
+## Update with an ETag
+
+If `users.get` supplies an ETag and `users.update` declares `params.id`, an `if-match` header,
+a `{ name }` payload, and its precondition failure, preserve the ETag for the write.
+Import `MutationObserver` from `@tanstack/query-core`:
+
+```ts
+if (etag === undefined) throw new Error('The server supplied no ETag')
+await queryClient.cancelQueries({ queryKey: http.users.get.key() })
+const updateUser = new MutationObserver(
+  queryClient,
+  http.users.update.mutationOptions({
+    onSuccess: () => queryClient.invalidateQueries({ queryKey: http.users.get.key() }),
+  }),
+)
+```
+
+Send the raw ETag **including quotes**, then read the refreshed metadata before another write:
+
+```ts
+await updateUser.mutate({
+  params: input.params,
+  headers: { 'if-match': etag },
+  payload: { name: 'Ada' },
+})
+const refreshed = await queryClient.query(metadataOptions)
+```
+
+The server enforces the precondition. Inspect its declared failure through the
+[HTTP execution error](/effect-api-query/guides/handle-failures/#inspect-http-failures).
+The invalidation prefix refreshes data and metadata entries.
+
+Native selection, initial data, skipping, and cancellation also apply. For precise immutability
+and structural-sharing behavior, see [Buffered Metadata](/effect-api-query/reference/http-builders/#buffered-metadata).

-Use your existing `http` utility tree and QueryClient. The examples below name the declared

-from your API. Import native observers/hooks from TanStack Query when using them.
+Use the HTTP utility tree from the [HTTP quick start](/effect-api-query/getting-started/http-quick-start/).

-## Create the utilities
+## Supply decoded request parts
 
-Create the tree in the application client module with your HttpApi and acquired client:
+HTTP input contains the declared `params`, `query`, `headers`, and `payload` containers.
+Include each declared container even when its fields are optional. For `users.get` declaring
+`params.id` and `query.locale`:
 
 ```ts
-const http = createHttpApiQueryUtils(api, { client, keyPrefix: ['my-app'] })
-```
-
-Import the factory from `effect-api-query`. Keep base URL, middleware and authentication on the
-ready client. When execution needs services, supply your application's signal-aware
-`runPromiseExit`. The [HTTP Quick Start](/effect-api-query/getting-started/http-quick-start/)
-shows factory, read and write setup.
-
-## Fetch a user
-
-For `users.get` declaring an integer `id` param, in a loader or event handler:
-
-```ts
-const userOptions = http.users.get.queryOptions({
-  input: { params: { id: 1 } },
+const httpUserOptions = http.users.get.queryOptions({
+  input: { params: { id: 1 }, query: { locale: 'en' } },
   staleTime: 30_000,
 })
-
-const user = await queryClient.query(userOptions)
-```
-
-Pass decoded values in every declared `params`, `query`, `headers`, and `payload` container,
-even when its fields are optional. The client encodes them; HTTP builders add no constructor
-defaults. An inputless endpoint uses `queryOptions()`.
-
-Pass `userOptions` to a native query hook for observation. `select` changes its result while
-`getQueryData(userOptions.queryKey)` still infers the decoded cache value.
-
-## Update with an ETag
-
-Suppose `users.get` supplies an ETag and `users.update` declares `id` params, an `if-match`
-header, a `{ name }` payload and its precondition error. In the write handler, read metadata:
-
-```ts
-const input = { params: { id: 1 } }
-const metadataOptions = http.users.get.metadataOptions({ input })
-const current = await queryClient.query(metadataOptions)
-const etag = current.headers['etag']
-if (etag === undefined) throw new Error('The server supplied no ETag')
-```
-
-Cancel affected reads and prepare the mutation with endpoint-prefix invalidation:
-
-```ts
-await queryClient.cancelQueries({ queryKey: http.users.get.key() })
-const update = new MutationObserver(
-  queryClient,
-  http.users.update.mutationOptions({
-    onSuccess: () => queryClient.invalidateQueries({ queryKey: http.users.get.key() }),
-  }),
-)
-```
-
-Execute that write with the ETag unchanged, **including quotes**:
-
-```ts
-await update.mutate({
-  params: input.params,
-  headers: { 'if-match': etag },
-  payload: { name: 'Ada' },
-})
-```
-
-After invalidation, fetch metadata again and use its next ETag before another write:
-
-```ts
-const refreshed = await queryClient.query(metadataOptions)
-```
-
-The server enforces the precondition; handle a declared failure through the HTTP execution
-error. The prefix refreshes both data and metadata entries. Metadata retains decoded success
-(including decoded header wrappers), status and copied frozen raw string headers in a separate
-cache view. Choose safe headers before persistence or hydration.
-
-[Buffered metadata](/effect-api-query/reference/http-factory/#buffered-metadata) specifies
-initial data, selection, immutable snapshots and structural sharing. A fresh imperative cache
-hit keeps existing Query options; install a changed policy through an observer or actual fetch
-before later manual writes.
-
-## Wait for request input
-
-In a React component, use the exported `skipToken` until the full request exists:
-
-```ts
-import { useQuery } from '@tanstack/react-query'
-import { skipToken } from 'effect-api-query'
-
-const user = useQuery(
-  http.users.get.queryOptions({
-    input: userId === undefined ? skipToken : { params: { id: userId } },
-    staleTime: 30_000,
-    select: (user) => user.name,
-  }),
-)
+const httpUser = await queryClient.query(httpUserOptions)
 ```
 
-Skipping keeps caller options and performs no encoding or request. For manual refetch, use
-`enabled: false` with complete input. [Conditional Queries](/effect-api-query/guides/conditional-queries/)
-covers sentinel, suspense and prefetch restrictions.
-
-## Load pages
-
-For `users.list` declaring `cursor` and `filter` query fields and returning
-`{ items, nextCursor }`, build options in the query consumer:
-
-```ts
-const filter = 'active'
-const pageOptions = http.users.list.infiniteOptions({
-  initialPageParam: 0,
-  input: (cursor) => ({ query: { cursor, filter } }),
-  getNextPageParam: (page) => page.nextCursor ?? undefined,
-  select: (data) => data.pages.flatMap((page) => page.items),
-})
-```
-
-Pass `pageOptions` to the native infinite hook. The initial mapped request determines identity;
-keep stable filters in every page and rebuild options when they change. The mapper runs during
-key construction and execution, so keep it deterministic and return all declared containers.
-`select` changes the observer result; cache data retains `pages` and `pageParams`.
-See [HTTP pagination](/effect-api-query/reference/http-factory/#pagination) for skipping,
-page inference and execution contracts.
-
-## Create a user and refresh the cache
-
-In the mutation module, prepare the write and refresh its affected branch:
-
-```ts
-const createUser = new MutationObserver(
-  queryClient,
-  http.users.create.mutationOptions({
-    onSuccess: () => queryClient.invalidateQueries({ queryKey: http.users.key() }),
-  }),
-)
-```
-
-In an event handler, supply this execution's complete decoded request:
-
-```ts
-await createUser.mutate({ payload: { name: 'Ada' } })
-```
-
-Native `useMutation` accepts the same options. Successful `undefined` query data becomes
-`null`; mutation results keep `undefined`. See [Handle Failures](/effect-api-query/guides/handle-failures/#inspect-http-failures).
+The ready client encodes decoded values; HTTP builders apply no RPC constructor defaults.
+Inputless endpoints use `queryOptions()`. Raw response controls are excluded from request input.

-  refetchMode: 'reset',
-  sseOptions: { maxEventSize: 1024 * 1024 },
-})
-```
-
-Pass `events` to the framework query hook or `QueryObserver`. The first emission is successful
-data while fetching continues. `maxChunks` bounds cached elements; omit it for unlimited
-history. It does not bound transport buffering. `reset`, `append` and `replace` choose refetch
-history; an open `replace` keeps old data until completion. Accumulated elements retain
-`undefined` and decoded header wrappers.
-
-`sseOptions.maxEventSize` bounds pending parser text in code units (default 10 MiB).
-Decoder and history policy affect exact identity; use the same policy with `streamedKey`, or
-reuse `events.queryKey`. Declared resume headers belong in `input.headers`. Reconnection,
-`Sse.Retry` and resume policy remain application-owned. See
-[HTTP streams](/effect-api-query/reference/http-factory/#accumulated-sse-options) for full policies,
-failures and omitted response shapes.
-
-## Keep the latest SSE value
-
-For snapshot-like emissions, in the same query consumer:

-```ts
-const latest = http.events.watch.liveOptions({
-  input: { query: { channel: 'news' } },
-  sseOptions: { maxEventSize: 1024 * 1024 },
-})
-```
-
-Pass `latest` to a native query hook or observer. Each emission replaces cached data; completion
-preserves it. Top-level `undefined` becomes `null`; a decoded header wrapper keeps its body.
-Empty completion raises `EffectHttpApiQueryEmptyStreamError`. Transport/decoding/event failures
-and independent interruption preserve their full Cause.
-
-Use `latest.queryKey` or `liveKey(input, { sseOptions })` for exact access. Live views accept no
-history bound/refetch mode and remain separate from accumulated views. Both support skipped
-input and endpoint-prefix filtering. Unsubscribe, cancel and drain local work before disposal;
-other observers retain their subscriptions. See [Client Lifecycle](/effect-api-query/concepts/client-lifecycle/).
-
-## Keep cache entries separate
-
-In a cache callback or event handler:
-
-```ts
-const key = http.users.get.queryKey({ params: { id: 1 } })
-const cachedUser = queryClient.getQueryData(key)
-await queryClient.invalidateQueries({ queryKey: http.users.key() })
+const payload = new FormData()

 ```

+Use your ready utility tree and QueryClient from the [RPC quick start](/effect-api-query/getting-started/quick-start/)
+or [HTTP quick start](/effect-api-query/getting-started/http-quick-start/).
+The examples assume `users.create` accepts a `name` and returns a user with `id` and `name`.
+Import `MutationObserver` from `@tanstack/query-core` for imperative execution.
+
+## Execute a write
+
+Build options once, then supply each mutation's variables when it runs:
+
+```ts
+const createUser = new MutationObserver(
+  queryClient,
+  rpc.users.create.mutationOptions({
+    onSuccess: () => queryClient.invalidateQueries({ queryKey: rpc.users.key() }),
+  }),
+)
+const created = await createUser.mutate({ name: 'Ada' })
+```
+
+HTTP variables contain the complete decoded request:
+
+```ts
+const createHttpUser = new MutationObserver(
+  queryClient,
+  http.users.create.mutationOptions({
+    onSuccess: () => queryClient.invalidateQueries({ queryKey: http.users.key() }),
+  }),
+)
+const createdHttpUser = await createHttpUser.mutate({ payload: { name: 'Ada' } })
+```
+
+Native mutation hooks accept the same options. Callbacks infer the result, variables, and
+execution errors. Mutation keys identify the operation and exclude variables. Successful
+`undefined` remains `undefined`.
+
+## Choose cache updates
+
+Writes refresh reads through your callback policy. Invalidate affected generated prefixes,
+seed a known result with `setQueryData`, or apply an
+[optimistic write](/effect-api-query/guides/optimistic-writes/).
+The library derives builders from the contract; the call site chooses read or write semantics.
+Buffered multipart endpoints support mutations only.
+
+See [HTTP uploads](/effect-api-query/guides/http-queries-and-mutations/#upload-a-file),

+title: Pagination
+description: Map page parameters to typed RPC payloads and HTTP requests.
+---
+
+Use a ready [RPC](/effect-api-query/getting-started/quick-start/) or
+[HTTP](/effect-api-query/getting-started/http-quick-start/) utility tree.
+These examples assume `users.page` accepts numeric `cursor` and `pageSize` fields and returns
+`{ users, nextCursor }`, with `null` marking the last page.
+
+## Build page options
+
+Map each page parameter to RPC payload constructor input:
+
+```ts
+const rpcPages = rpc.users.page.infiniteOptions({
+  initialPageParam: 0,
+  input: (cursor) => ({ cursor, pageSize: 20 }),
+  getNextPageParam: (page) => page.nextCursor ?? undefined,
+})
+const pages = await queryClient.infiniteQuery(rpcPages)
+```
+
+For HTTP, return every declared request container from the mapper:
+
+```ts
+const httpPages = http.users.page.infiniteOptions({
+  initialPageParam: 0,
+  input: (cursor) => ({ query: { cursor, pageSize: 20 } }),
+  getNextPageParam: (page) => page.nextCursor ?? undefined,
+})
+```
+
+Pass these options to the native infinite-query hook to load further pages with `fetchNextPage`.
+Inputless operations omit `input`. Input-bearing operations can pause with `input: skipToken`;
+see [Conditional Queries](/effect-api-query/guides/conditional-queries/).
+
+## Keep page identity stable
+
+The mapped initial request determines cache identity. Keep filters in that request and every
+page; rebuild options when filters change. The mapper runs during key construction and page
+execution, so keep it deterministic.
+
+TanStack stores `pages` and `pageParams`. A native `select` can flatten returned data while cache
+reads retain the original pages and inferred page-parameter type:
+
+```ts
+const cachedPages = queryClient.getQueryData(httpPages.queryKey)
+```
+
+Infinite views have separate keys from ordinary queries. Every page uses the query runner and
+abort signal. See [RPC Builders](/effect-api-query/reference/generated-builders/#build-an-infinite-query)
+and [HTTP Builders](/effect-api-query/reference/http-builders/#pagination) for exact option contracts.

+title: Queries
+description: Build typed query options for cached RPC and HTTP reads.
+---
+
+Start with a ready utility tree and QueryClient from the [RPC quick start](/effect-api-query/getting-started/quick-start/)
+or [HTTP quick start](/effect-api-query/getting-started/http-quick-start/).
+Here, `users.get` returns a user with `id` and `name`; its RPC payload has an `id` and default locale.
+The HTTP endpoint declares `params.id` and `query.locale`.
+
+## Fetch decoded data
+
+Pass RPC payload constructor input to `queryOptions`:
+
+```ts
+const userOptions = rpc.users.get.queryOptions({ input: { id: 1 }, staleTime: 30_000 })
+const user = await queryClient.query(userOptions)
+```
+
+HTTP options take the complete decoded request. Include every declared container:
+
+```ts
+const httpUserOptions = http.users.get.queryOptions({
+  input: { params: { id: 1 }, query: { locale: 'en' } },
+  staleTime: 30_000,
+})
+const httpUser = await queryClient.query(httpUserOptions)
+```
+
+These options also work with native query, suspense, and prefetch hooks. An inputless operation
+uses `queryOptions()`. Queries cache decoded success, with top-level `undefined` converted to `null`.
+Keep captured input values unchanged while using the options.
+
+## Select returned data
+
+Native options such as `staleTime`, `retry`, and `select` pass through:
+
+```ts
+const nameOptions = rpc.users.get.queryOptions({
+  input: { id: 1 },
+  select: (user) => user.name,
+})
+const selectedName = await queryClient.query(nameOptions)
+const cachedUser = queryClient.getQueryData(nameOptions.queryKey)
+```
+
+Hooks, observers, and `queryClient.query` return the selected name. The cache and `getQueryData`
+retain the decoded user; generated keys preserve that type. Builders supply `queryKey` and `queryFn`.
+Configure hashing through [QueryClient defaults](/effect-api-query/guides/query-defaults/).
+
+Continue with [Conditional Queries](/effect-api-query/guides/conditional-queries/),
+[Cache Management](/effect-api-query/guides/cache-management/), or your framework's integration guide.

+title: Streaming
+description: Cache accumulated or latest values from RPC streams and HTTP SSE.
+---
+
+Streaming leaves provide two views: an accumulated streamed query caches emissions in order;
+a live query caches the latest value. Use ordinary query hooks or `QueryObserver` for both.
+Start with a ready [RPC](/effect-api-query/getting-started/quick-start/) or
+[HTTP](/effect-api-query/getting-started/http-quick-start/) utility tree.
+Here, `diagnostics.stream` is an inputless RPC emitting strings, and `events.watch` is an HTTP SSE
+endpoint declaring `query.channel` and emitting strings.
+
+## Accumulate values
+
+Choose a finite history for a long-running feed:
+
+```ts
+const history = rpc.diagnostics.stream.streamedOptions({
+  maxChunks: 100,
+  refetchMode: 'reset',
+})
+```
+
+HTTP SSE supports the same history controls and a separate decoder limit:
+
+```ts
+const sseHistory = http.events.watch.streamedOptions({
+  input: { query: { channel: 'news' } },
+  maxChunks: 100,
+  sseOptions: { maxEventSize: 1024 * 1024 },
+})
+```
+
+The first emission makes the query successful while fetching continues. `maxChunks` bounds
+cached elements after each emission; omitted means unlimited. It does not bound bytes or
+transport buffering. Refetch mode `reset` starts a new history, `append` adds to it, and `replace`
+keeps the old history until successful completion. An indefinitely open replacement keeps
+showing that old history. Accumulated streams can succeed without emissions.
+
+## Keep the latest value
+
+Choose live options for current state:
+
+```ts
+const latest = rpc.diagnostics.stream.liveOptions()
+const latestSse = http.events.watch.liveOptions({
+  input: { query: { channel: 'news' } },
+  sseOptions: { maxEventSize: 1024 * 1024 },
+})
+```
+
+Each emission replaces cached data; completion preserves it. Live queries convert top-level
+`undefined` to `null`, while accumulated elements retain `undefined`. Empty live completion
+raises the adapter's empty-stream error. Live options accept neither `maxChunks` nor `refetchMode`.
+
+## Address and stop a view
+
+Reuse the options' `queryKey` for exact cache access. Accumulated history policies and HTTP decoder
+policies affect identity; live and accumulated views remain separate. Endpoint prefixes match
+all their views.
+
+Cancellation closes the stream iterator. Your application owns reconnection, resume policy,
+and client lifetime. HTTP `sseOptions.maxEventSize` bounds pending parser text in JavaScript string
+code units; its default is 10 × 1024 × 1024 code units. Declared resume headers belong in `input.headers`.
+
+See [Choose Stream History](/effect-api-query/guides/choose-stream-history/) for retention and
+buffering, [Stream Snapshots](/effect-api-query/guides/stream-snapshots/) for finite server captures,
+and [Client Lifecycle](/effect-api-query/concepts/client-lifecycle/) for cleanup ownership.

+title: HTTP Builders
+description: HTTP query, metadata, mutation, pagination, and SSE option contracts.
+---
+
+Every retained branch and endpoint provides `key()` for prefix filtering. The
+[HTTP Factory](/effect-api-query/reference/http-factory/) specifies construction, supported endpoint
+shapes, and the decoded request contract.
+
+Query key builders return immutable, data-tagged keys. Option builders return fresh native
+Query Core options for the corresponding view.
+
+| Builder                                                     | View                                                         |
+| ----------------------------------------------------------- | ------------------------------------------------------------ |
+| `queryKey(input?)`, `queryOptions(options?)`                | Decoded query data.                                          |
+| `metadataKey(input?)`, `metadataOptions(options?)`          | Decoded data, status, and raw headers.                       |
+| `infiniteKey(input?)`, `infiniteOptions(options)`           | Native `InfiniteData` for paginated responses.               |
+| `mutationKey()`, `mutationOptions(options?)`                | Mutation options whose variables are supplied at execution.  |
+| `streamedKey(input?, policy?)`, `streamedOptions(options?)` | Accumulated SSE emissions with retention and decoder policy. |
+| `liveKey(input?, policy?)`, `liveOptions(options?)`         | Latest SSE emission with decoder policy.                     |
+
+Input-bearing key builders require the complete request. Inputless streamed and live key
+builders take their policy as the first argument. Buffered multipart endpoints expose only
+mutation builders; SSE endpoints expose only accumulated and live builders.
+
+## Query options
+
+See [Queries](/effect-api-query/guides/queries/) for usage.
+
+Ordinary options work with native query, suspense, and prefetch hooks and QueryClient operations.
+Callbacks retain the decoded result, complete failure union, and request types. `select` changes
+consumer data; data-tagged keys retain the underlying cache data and error types. The type of
+`initialData`, whether defined or possibly undefined, preserves the corresponding TanStack hook
+overload.
+
+Applicable TanStack options pass through. The package owns the key and function and removes
+`input` before returning options. QueryClient global and prefix defaults own hashing. Builders
+reject per-call `queryKeyHashFn` and `queryHash` with `EffectHttpApiQueryConfigError` code
+`UnsupportedQueryHash`.
+Keep hash defaults stable while entries remain cached. Stream execution also rejects with that
+code when changed hashing conflicts with a matching cached entry.
+
+Input-bearing `queryOptions` accepts a complete request in `input` or
+`queryOptions({ input: skipToken, ...options })`. Import `skipToken` from `effect-api-query` or
+TanStack. Skipping preserves caller options and returns the exact sentinel as `queryFn`, with the
+operation-level key and no request identity. It performs no request encoding or client call.
+Supplied initial data remains available, but native skipped hook data stays possibly undefined.
+
+Inputless builders, key builders, and mutations reject `skipToken`. A skipped function cannot run
+through manual refetch; supply valid input or use `enabled: false` with a complete request when
+manual execution is required. Native suspense and prefetch-only hooks reject skipped options.
+
+## Mutation options
+
+`mutationOptions(options?)` supplies `mutationKey` and `mutationFn`. Pass the complete decoded
+request as variables when a native mutation hook or observer executes it. Variables never enter
+the key. Callbacks retain result, request, and execution-error types. Successful `undefined`
+remains `undefined`.
+
+Mutations have no query abort signal and no automatic relationship to cached reads. Choose
+invalidation, seeding, or optimistic updates in native callbacks; see
+[Mutations](/effect-api-query/guides/mutations/).
+
+## Buffered metadata
+
+Query-enabled buffered endpoints also provide `metadataKey(request)` and `metadataOptions({ input,
+...options })`; inputless endpoints omit the request. The ready client runs in decoded-and-response
+mode, and the cache contains:
+
+```ts
+type Metadata<DecodedSuccess> = {
+  readonly data: QueryData<DecodedSuccess>
+  readonly status: number
+  readonly headers: Readonly<Record<string, string>>
+}
+```
+
+The outer envelope and copied plain header record are frozen. `data` preserves the declared decoded
+value and its ownership, including decoded `WithHeaders` wrappers. Only top-level successful
+`undefined` becomes `null`. Raw headers retain their string values without Effect's inspection
+redaction; applications decide which headers may be persisted or dehydrated.
+
+Fetched snapshots remain frozen after structural sharing. Global and prefix sharing policies apply
+to fetched data; a policy passed to `metadataOptions` overrides them. Mutable envelopes or header
+records selected by sharing are copied
+before freezing, retaining the selected decoded data reference. The adapter does not freeze
+decoded data or caller-supplied `initialData`, hydrated values, or manual cache writes.
+
+Selected observer results and, after execution, manual cache writes use the sharing policy explicitly
+passed to `metadataOptions`, or standard deep sharing when it is absent. Inherited global and prefix
+sharing policies apply only to fetched metadata snapshots.
+
+A fresh-cache hit from imperative `queryClient.query(newOptions)` retains the Query's existing
+options. Install a changed sharing policy through an observer or an actual fetch before relying
+on it for later manual writes.
+
+Metadata keys use a `metadata` discriminator and the ordinary request identity. Endpoint prefixes
+match every view. Native `select`, `initialData`, skip-token inference, QueryClient hashing defaults,
+and cancellation apply to metadata options. Execution failures identify operation `metadata` and
+preserve that client mode's full error and service channels. Metadata adds no mutation or infinite
+builders and is absent on multipart and streaming endpoints.
+
+The cache retains the decoded value and metadata snapshot, without a response object or open body.
+See [Update with an ETag](/effect-api-query/guides/http-metadata/#update-with-an-etag)
+for conditional writes.
+
+## Accumulated SSE options
+
+`streamedOptions` accepts native query options, decoded `input` when declared, and:
+
+| Option                    | Contract                                                                                                |
+| ------------------------- | ------------------------------------------------------------------------------------------------------- |
+| `maxChunks`               | Positive safe integer limiting retained events; omitted means unlimited.                                |
+| `refetchMode`             | `reset` (default), `append`, or `replace`.                                                              |
+| `sseOptions.maxEventSize` | Positive safe integer limiting pending parser text; defaults to 10 MiB of JavaScript string code units. |
+
+Decoded data is an ordered readonly array. Accumulated elements keep `undefined`; decoded header
+wrappers surround each emitted body. Empty completion succeeds. Acquisition and consumption errors
+use `EffectHttpApiQueryError` with operation `streamed`, preserving declared event failures,
+`Sse.Retry`, `Sse.SseError`, HTTP and Schema errors, and additional client channels.
+The caller's runner supplies acquisition and consumption services and receives Query's abort signal.
+Cancellation closes the iterator and follows native Query cache reversion.
+
+`streamedKey(input, policy)` accepts the same decoder, retention, and refetch policy; inputless
+endpoints use `streamedKey(policy)`. Equivalent defaults have equal keys. Different effective
+policies occupy separate entries. Endpoint `key()` selects them all. Decoder controls are excluded
+from decoded request input and custom encoders. Declared resume headers remain request identity.
+
+See [Accumulate Values](/effect-api-query/guides/streaming/#accumulate-values).
+
+## Live SSE options
+
+`liveOptions` accepts native query options, declared decoded `input`, and `sseOptions`.
+`liveKey(input, { sseOptions })`, or `liveKey({ sseOptions })` for inputless endpoints, includes
+normalized decoder policy in its separate `live` identity. Its keys carry the latest decoded value
+and the execution error union, including `EffectHttpApiQueryEmptyStreamError`. Live builders
+preserve selection, initial-data, and skipped-input inference.
+
+The first emission makes the query successful. Later emissions replace the cached value, and
+completion preserves the latest value. Only a top-level `undefined` becomes `null`; declared
+header wrappers retain their decoded body and headers. An empty live completion fails with
+declaration metadata. Live queries accept no `maxChunks` or accumulated `refetchMode`.
+
+The acquisition and consumption error/service channels, decoder limit validation, iterator cleanup,
+and caller-owned reconnection contract match accumulated SSE queries. Input-bearing builders
+validate decoder policy even when skipped. Endpoint prefixes match both representations and every
+concrete decoder policy. See [Keep the Latest Value](/effect-api-query/guides/streaming/#keep-the-latest-value).
+
+## Pagination
+
+`infiniteOptions` requires `initialPageParam` and `getNextPageParam`. For an input-bearing endpoint,
+`input(pageParam)` returns the complete decoded HTTP request for that page. Inputless endpoints
+omit `input`. Input-bearing endpoints can pause with `input: skipToken` in the options object;
+the direct sentinel form is unavailable.
+
+The initial request determines cache identity. Infinite keys use an `infinite` discriminator, so
+they remain separate from ordinary queries for the same request. `infiniteKey(request)` builds
+the corresponding key from a complete initial request; `infiniteKey()` serves inputless endpoints.
+Keys returned by `infiniteOptions` also retain the inferred page-parameter type for cache reads.
+
+Keep stable filters in the initial request and every page. Change the initial request when those
+filters change, and advance cursors through `getNextPageParam`. The input mapper must be
+deterministic: the builder evaluates it for the initial key, and execution evaluates it for every
+page.
+
+QueryClient stores native `InfiniteData` and owns invalidation and refetching. Selections can
+transform consumer data without changing cached pages. Every page preserves the
+ordinary HTTP execution contract, including `undefined`-to-`null` normalization, wrapped errors,
+and cancellation. See [Pagination](/effect-api-query/guides/pagination/).
+
+## Cache identity and failures
+
+HTTP keys begin with `keyPrefix`, `http`, and the HttpApi identifier, followed by the projected
+endpoint path and operation discriminator. Query keys append canonical request identity when the
+endpoint has input. `utils.key()` includes the generated root and matches every HTTP descendant.
+RPC utilities use a separate `rpc` discriminator. Use the original caller prefix deliberately
+when invalidating across both adapters.
+
+Default query preparation synchronously encodes the declared `params`, `query`, `payload`, and
+`headers` schemas. The key retains these labels, including when a bodyless method sends its payload
+as URL parameters. Preparation uses the endpoint's effective schemas without constructing an HTTP
+request or body. The same rule applies to JSON, text, form-urlencoded requests, and requests without
+bodies.
+
+Encoded object members whose value is `undefined` are omitted. An encoded `null` stays `null`,
+including when Effect's JSON codec produces it from a decoded optional value. Arrays retain their
+order; sparse arrays and encoded `undefined` items are rejected. Header field names become lowercase;
+equal duplicates collapse and conflicting duplicates fail. Other values follow strict canonical
+JSON: finite numbers, plain objects, copied arrays, sorted object properties, cycle rejection, and
+deep freezing.
+
+For endpoints with query support, multiple effective payload schemas require a custom encoder,
+including alternatives with the same content type. Types enforce this requirement when declarations retain distinct schemas. Runtime
+validation also covers alternatives that the declaration types no longer distinguish. Buffered binary
+input needs an explicit JSON-safe projection because default keys cannot contain `Uint8Array`. See
+[custom key encoders](/effect-api-query/guides/custom-key-encoders/#http-requests).
+
+`EffectHttpApiQueryKeyError` identifies the API, group, endpoint, and method and distinguishes:
+
+| Code                    | Trigger                                                                   |
+| ----------------------- | ------------------------------------------------------------------------- |
+| `RequestEncodingFailed` | A default request-schema encoder fails.                                   |
+| `KeyEncoderFailed`      | A custom encoder throws.                                                  |
+| `InvalidKeyValue`       | Encoded identity violates canonical JSON or has conflicting header names. |
+
+These failures occur in `queryKey` or `queryOptions`, before the client runs. Mutation preparation
+does not encode a query key; request encoding runs inside the ready client's Effect. Custom encoder
+output follows strict JSON and bypasses the default HTTP rules for omitting `undefined` members
+and normalizing headers.
+
+Multipart mutation keys contain no request variables or files. `mutationKey()` identifies the
+operation, and `key()` retains the endpoint's normal invalidation prefix. Use mutation callbacks
+to invalidate the affected read endpoints. Multipart leaves have no query or infinite-query builders.
+
+`EffectHttpApiQueryError` wraps a failed execution `Exit`, identifies the API, group, endpoint,
+method, and operation, and preserves its complete Cause. The package adds no concrete request
+values to that metadata; upstream Causes can still contain requests, responses, or Schema issue
+values. `isEffectHttpApiQueryError` narrows execution errors. Configuration and key preparation
+failures use `EffectHttpApiQueryConfigError` and `EffectHttpApiQueryKeyError` respectively.

+- **Usability and policy reuse (2026-10-11), based on `8f4723c`:** extend the
+  existing skill and six references with operation inference, supported view
+  prefixes, typed query/mutation policy reuse, minimal native provider setup,
+  Suspense recovery, and consumed-stream tracing. Keep inputs, projections, seeds,
+  page mapping, stream identity, and optimistic context local; call-site callbacks
+  replace shared policy callbacks. Preserve native QueryClient defaults, canonical
+  encoded partial filtering, application lifetime, and all prior task coverage.
+  Semantic near-miss duplication detection found the repeated retry recipe;
+  shared owner invalidation and error descriptions also reduce example drift.
+  Expand source mappings for TSX fixtures and shared example error rendering.
+  A fresh consumer invoked the copied packaged skill and produced typed policy
+  builders in a disposable project. The behavior checks passed and rejected the
+  initial version without shared defaults; its result compiled on TypeScript 7
+  and 5.9. Skill discovery remains unverified. Final compiler, runtime,
+  documentation, and revision-bound Intent outcomes are recorded with the task's
+  maintenance review.
+- **Library-focused documentation (2026-10-11), based on `8f4723c`:** separate
+  library contracts, native integrations, runnable application examples, and API
+  reference. Keep the existing fourteen tasks and six shipped references.
+  Type Inference owns the detailed inference contract; Defaults and Policies owns
+  shared defaults and callbacks; Cache Keys and Filters replaces Cache Management.
+  Fold ready-client mounting into React Query and move the explicit command
+  protocol to Cancellable Commands. Update shipped pointers to those canonical
+  pages and the integration overview. Existing skill-tree source patterns already
+  cover the new and moved pages, so its identities and mappings remain accurate.
+  Preserve the fresh-consumer evidence above; this reorganization changes where
+  guidance is reached, without changing its recommended API behavior.

-title: Query and Mutation Operations
-description: Choose queries, mutations, pagination, or streams for your API calls.
+title: Generated Utility Model
+description: Understand the contract, input, data, error, and cache identity carried by generated leaves.
 ---
 
-Every unary RPC leaf and buffered HTTP endpoint without multipart has query, infinite-query,
-and mutation builders. Your application chooses how to use each operation; neither the RPC
-definition nor the HTTP method determines the builder. Buffered multipart HTTP endpoints expose
-mutations only. Streaming RPCs and unambiguous HTTP SSE endpoints expose accumulated and live
-builders. Mixed buffered/SSE successes, raw byte streams, and multipart SSE endpoints are omitted.
+A factory combines an Effect declaration with its ready client and a caller-supplied key prefix.
+It eagerly builds an immutable utility tree. Branches represent declaration namespaces;
+leaves represent RPCs or supported HTTP endpoints. Each leaf supplies the builders for the views
+its contract supports.
 
-Use a query when TanStack should cache a result by semantic request identity. For RPCs with a
-payload, the query key contains the normalized, canonical payload. TanStack can refetch or cancel the query.
+## What a generated leaf carries
 
-Use a mutation when the call represents an action or write. Pass variables when the mutation
-runs; their values do not become part of the mutation key.
+| Part              | Contract                                                                                   |
+| ----------------- | ------------------------------------------------------------------------------------------ |
+| Input             | RPC payload constructor input or the complete decoded HTTP request                         |
+| Query data        | Decoded data for the selected cache view, before an observer's `select`                    |
+| Execution failure | Declaration identity plus the complete Effect Cause from a failed Exit                     |
+| Cache identity    | Caller prefix, adapter/declaration path, view, canonical input, and applicable view policy |
+| Options           | Generated key and function with the applicable native TanStack options                     |
 
-Use an infinite query when TanStack should accumulate paginated results. Map each page parameter
-to an RPC payload or complete decoded HTTP request; the mapped initial request becomes part of
-the semantic key. Keep stable filters in every page request. See
-[HTTP pagination](/effect-api-query/guides/pagination/) or
-[RPC pagination](/effect-api-query/guides/pagination/).
+Ordinary buffered reads cache decoded data. Infinite queries cache pages and page parameters.
+Accumulated streamed queries cache emissions in order; live queries cache the latest value.
+HTTP metadata caches decoded data beside immutable status and raw-header snapshots.
+Mutation variables are execution input and do not become mutation-key identity.
 
-Use an accumulated streamed query when the application needs every emitted value in order. Use a
-live query when it needs only the latest emitted value. Both operations close their stream iterator
-when TanStack cancels the query.
+See [Feature Support](/effect-api-query/getting-started/feature-support/) for supported contract
+shapes. [RPC Utility Tree](/effect-api-query/concepts/rpc-utility-tree/) explains dotted tags;
+[HTTP Utility Tree](/effect-api-query/concepts/http-utility-tree/) explains literal group and endpoint
+identifiers and omitted endpoints.
 
-```ts
-const user = useQuery(rpcQuery.users.get.queryOptions({ input: { id: 1 } }))
+## Keep input, cached data, and observer data distinct
 
-const removeUser = useMutation(rpcQuery.users.delete.mutationOptions())
-removeUser.mutate({ id: 1 })
-```
+RPC constructors can supply defaults before key preparation. HTTP builders accept decoded request
+containers without RPC construction. Equivalent canonical input shares identity, while distinct
+views remain separate. See [Inputs and Query Data](/effect-api-query/concepts/data-normalization/)
+and [Semantic Keys](/effect-api-query/concepts/semantic-keys/).
 
-After a successful mutation, invalidate the affected query prefix explicitly. The package does not
-infer relationships between API operations.
+An observer's `select` projects data without changing the cached representation. Buffered and
+live `undefined` values become `null`; mutation results and accumulated stream elements retain
+`undefined`. Infer these types from the generated leaf when extracting reusable application code.
+
+## Ownership at the boundary
+
+The package owns generated keys/functions, view identity, and adaptation of failed Effect Exits.
+TanStack owns caching, observers, retries, invalidation, and framework hooks. The application owns
+ready clients, runtimes, transport, authentication, providers, lifecycle, and relationships between
+writes and reads.
+
+The same generated options work in native QueryClient calls, framework hooks, and router loaders.
+[Defaults and Policies](/effect-api-query/guides/query-defaults/) keeps reusable policy attached to
+the leaf's types. [Integrations](/effect-api-query/integrations/) shows each consumer's wiring.

+title: Cancellable Commands
+description: Run the example's explicit command protocol without treating mutation cancellation as rollback.
+---
+
+This application workflow demonstrates long-running server work with an operation ID, observable
+progress, and an explicit cancellation request. Run the
+[Vite React example](/effect-api-query/examples/#run-vite-react) and use the **Cancellable commands**
+panel. The Start application serves the same contract and handlers.
+
+The library supplies ordinary generated query and mutation options. The application supplies the
+command protocol, server workers, progress policy, and retention. For query signals and iterator
+cleanup, see the [Cancellation contract](/effect-api-query/guides/cancellation/).
+
+## Cancel a command while its mutation is pending
+
+Use an explicit cancel RPC for long-running commands. The Vite React example provides
+`commands.start`, `commands.status`, and `commands.cancel` in the shared contract. Each command
+has a client-generated operation ID. The start mutation waits for a terminal result; a separate
+query observes progress, and a separate mutation requests cancellation.
+
+In the React component setup, import `useState`, `useQuery`, and `useMutation` from their native
+packages. With the example's ready `rpcQuery` and QueryClient:
+
+```ts
+const [operationId] = useState(() => crypto.randomUUID())
+const input = { operationId }
+const reconcile = async () => {
+  await queryClient.invalidateQueries({
+    queryKey: rpcQuery.commands.status.queryKey(input),
+  })
+}
+
+const start = useMutation(rpcQuery.commands.start.mutationOptions({ onSettled: reconcile }))
+const cancel = useMutation(rpcQuery.commands.cancel.mutationOptions({ onSettled: reconcile }))
+const status = useQuery(
+  rpcQuery.commands.status.queryOptions({
+    input,
+    enabled: start.status !== 'idle',
+    refetchInterval: (query) =>
+      query.state.data?.state === 'running' ||
+      query.state.status === 'error' ||
+      query.state.data === undefined ||
+      (query.state.data === null && start.isPending)
+        ? 100
+        : false,
+  }),
+)
+```
+
+In the start and cancel button handlers, call the corresponding mutation:
+
+```ts
+start.mutate(input)
+cancel.mutate(input)
+```
+
+Disable start while pending, after success, or when status confirms an accepted command.
+After a failed start with no accepted command, retry with the same operation ID; an uncertain
+response must not create a second command. Disable cancel before start, while cancellation is
+pending, or after a terminal status. The
+[complete command panel](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/components/sections/commands-section.tsx)
+includes the UI.
+
+The cancel handler signals the worker and waits until it has stopped. The cancel mutation's
+`onSettled` callback then invalidates the generated status key. The active query refetches the
+server's status even if the cancel request failed. Poll unresolved or failed status reads and
+running commands. Stop at a terminal status, or when a settled start has no corresponding command.
+The application chooses this invalidation policy.
+
+A cancelled command returns `{ state: 'cancelled', ... }` successfully. TanStack therefore reports
+both mutations as `success` and runs their normal callbacks. The domain state does not add a
+`cancelled` MutationCache state. Each operation ID has its own query key and worker, so cancelling
+one command leaves another running.
+
+Run the Vite React example and use the **Cancellable commands** panel to try two concurrent
+commands. The TanStack Start application hosts the same contract and handlers at `/rpc`; its
+`application.rpcQuery.commands` exposes these same framework-neutral options for hooks, loaders,
+and QueryClient. It can reuse the workflow above with its own QueryClient.
+
+## Choose what cancellation means
+
+| Action                    | Result                                                                                      |
+| ------------------------- | ------------------------------------------------------------------------------------------- |
+| Stop observing a query    | Removes local observation; whether work stops depends on the query lifecycle and transport. |
+| Interrupt an Effect       | Requests cooperative interruption and runs its finalizers.                                  |
+| Call `commands.cancel`    | Requests cooperative server cancellation by operation ID and waits for a terminal state.    |
+| Compensate committed work | Requires a separate application operation that reverses or offsets prior effects.           |
+
+Transport interruption is cooperative and depends on transport support. An explicit cancel RPC is the
+durable application contract for requesting server cancellation. The slow-query demo
+adds a transport-specific `diagnostics.cancel` call when its local Effect is interrupted; the
+package itself does not provide that behavior.
+
+The command example owns workers in the server Scope. Unmounting a view or interrupting the
+client's wait does not cancel these workers automatically. A cancel request stops future steps;
+completed steps remain recorded. Cancellation after completion returns the completed result without
+promising a rollback. Repeating a start with the same ID returns the existing result; a cancel
+that arrives before start reserves that ID as cancelled.
+
+This example stores operation records in memory until the example is reset or the server stops.
+Production applications need their own authorization, durable storage, and retention policy if
+operations must survive restarts. The explicit RPC contract does not make this in-memory example
+a durable job queue.

-plus `users.create` with a `{ name }` payload.

+First [install the package](/effect-api-query/getting-started/installation/). The server must

+server and browser application.
 
-Import `createHttpApiQueryUtils` from `effect-api-query` and `MutationObserver` from
-`@tanstack/query-core`. The [complete typed recipe](https://github.com/ueberBrot/effect-api-query/blob/main/tests/types/docs-http-quick-start.ts)

-```ts
-const http = createHttpApiQueryUtils(usersApi, {

+The [Cancellable Commands example](/effect-api-query/examples/cancellable-commands/) shows one
+protocol with start, status, and cancel operations. It also covers retries with the same operation ID,
+concurrent commands, and the limits of its in-memory workers.
 
-In the start and cancel button handlers, call the corresponding mutation:
+## Release resources after local cleanup
 
-```ts
-start.mutate(input)
-cancel.mutate(input)
-```
+Cancelling a query and releasing its services are separate steps. Native `cancelQueries` settlement
+can precede asynchronous iterator finalizers. Keep the ready client, its Scope, and the runner alive
+until application-owned cleanup signals settle. Mutations settle independently because they have
+no query abort signal.
 
-Disable start while pending, after success, or when status confirms an accepted command.
-After a failed start with no accepted command, retry with the same operation ID; an uncertain
-response must not create a second command. Disable cancel before start, while cancellation is
-pending, or after a terminal status. The
-[complete command panel](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/components/sections/commands-section.tsx)
-includes the UI.
-
-The cancel handler signals the worker and waits until it has stopped. The cancel mutation's
-`onSettled` callback then invalidates the generated status key. The active query refetches the
-server's status even if the cancel request failed. Poll unresolved or failed status reads and
-running commands. Stop at a terminal status, or when a settled start has no corresponding command.
-The application chooses this invalidation policy.
-
-A cancelled command returns `{ state: 'cancelled', ... }` successfully. TanStack therefore reports
-both mutations as `success` and runs their normal callbacks. The domain state does not add a
-`cancelled` MutationCache state. Each operation ID has its own query key and worker, so cancelling
-one command leaves another running.
-
-Run the Vite React example and use the **Cancellable commands** panel to try two concurrent
-commands. The TanStack Start application hosts the same contract and handlers at `/rpc`; its
-`application.rpcQuery.commands` exposes these same framework-neutral options for hooks, loaders,
-and QueryClient. It can reuse the workflow above with its own QueryClient.
-
-## Choose what cancellation means
-
-| Action                    | Result                                                                                      |
-| ------------------------- | ------------------------------------------------------------------------------------------- |
-| Stop observing a query    | Removes local observation; whether work stops depends on the query lifecycle and transport. |
-| Interrupt an Effect       | Requests cooperative interruption and runs its finalizers.                                  |
-| Call `commands.cancel`    | Requests cooperative server cancellation by operation ID and waits for a terminal state.    |
-| Compensate committed work | Requires a separate application operation that reverses or offsets prior effects.           |
-
-Transport interruption is cooperative and depends on transport support. An explicit cancel RPC is the
-durable application contract for requesting server cancellation. The slow-query demo
-adds a transport-specific `diagnostics.cancel` call when its local Effect is interrupted; the
-package itself does not provide that behavior.
-
-The command example owns workers in the server Scope. Unmounting a view or interrupting the
-client's wait does not cancel these workers automatically. A cancel request stops future steps;
-completed steps remain recorded. Cancellation after completion returns the completed result without
-promising a rollback. Repeating a start with the same ID returns the existing result; a cancel
-that arrives before start reserves that ID as cancelled.
-
-This example stores operation records in memory until the example is reset or the server stops.
-Production applications need their own authorization, durable storage, and retention policy if
-operations must survive restarts. The explicit RPC contract does not make this in-memory example
-a durable job queue.
+Follow [Client Lifecycle](/effect-api-query/concepts/client-lifecycle/) for disposal. Use
+[Stream Snapshots](/effect-api-query/guides/stream-snapshots/) for a finite capture that waits for
+local iterator cleanup before it settles.

-TanStack merges the QueryClient's global query defaults, every matching registered prefix in

-first: TanStack does not sort them by specificity. Here the query inherits `gcTime: 600_000`,
-`retry: 2`, and `staleTime: 120_000`. `refreshUser` overrides freshness and retries for that call.
-
-`rpc.key()` covers the utility tree, `rpc.users.key()` covers its branch, and
-`rpc.users.get.key()` covers the leaf. Appending `'query'` targets that leaf's ordinary query view
-without applying its stale policy to an infinite or stream view. An operation prefix also covers
-all inputs of that view. Mutation policies use native `setMutationDefaults` separately.
+This five-second policy applies to metadata without changing the ordinary view's freshness.
+Register mutation defaults separately with native `setMutationDefaults` and `mutationKey()`.
+See [Cache Keys and Filters](/effect-api-query/guides/cache-filters/) for prefix scopes.
 
-Omit an option to inherit its defaults. Use `staleTime: 0` to override an inherited freshness
-policy with immediate staleness. QueryClient imperative fetches and observers can have different
-built-in retry defaults, so set retry policy explicitly when attempts matter. `retry: 2` allows at
-most three executions. For typed decisions
-based on domain failures or transport errors, pass `retry` to the builder as shown in
-[Retry Queries](/effect-api-query/guides/retry-queries/).
+Configure hashing through QueryClient defaults before using the cache, and keep it stable for the

+[Semantic Keys](/effect-api-query/concepts/semantic-keys/) for the identity contract.
 
-## Apply HTTP policies to separate views

-HTTP prefixes use the same native APIs. This example retries the `users` group once, applies a
-five-second stale time only to the metadata view, and hashes every view through QueryClient's
-root-prefix policy. The ordinary query retains the global thirty-second stale time.
-
-In the same application cache module, with an existing `http` tree:
+Use `withQueryPolicy` when a policy belongs to one leaf and view. `QueryPolicy` gives reusable
+objects that leaf's native option types; retry and refetch callbacks retain its data and error types.
+Import both from `effect-api-query`:
 
 ```ts
-queryClient.setQueryDefaults(http.key(), {
-  queryKeyHashFn: (key) => `users:${JSON.stringify(key)}`,
-})
-queryClient.setQueryDefaults(http.users.key(), { retry: 1 })
-queryClient.setQueryDefaults([...http.users.get.key(), 'metadata'], { staleTime: 5_000 })

+const user = userOptions({ input: { id: 1 }, select: (value) => value.name })
+const refreshUser = userOptions({ input: { id: 1 }, staleTime: 0, retry: false })
 ```
 
-In its query consumer:
+The returned builder keeps selected-data, defined-initial-data, skipped-input, and page-parameter
+inference. `QueryPolicy<Leaf, View>` supports only that leaf's query views: `query`, `infinite`,
+`metadata`, `live`, or `streamed`. Specify the view in the type when it is not `query`.
+See [Type Inference](/effect-api-query/reference/type-inference/) for cache and failure types, and
+[Retry Queries](/effect-api-query/guides/retry-queries/) for reusable domain-aware decisions.

-const input = { params: { id: 1 } }
-const user = http.users.get.queryOptions({ input })
-const metadata = http.users.get.metadataOptions({ input })
-```
+Policies accept applicable native freshness, retry, refetch, and cache settings. Keep input,
+`select`, initial and placeholder data, page parameters and mappers, and adapter controls at the
+call site. Stream retention and decoder policies determine cache identity and also stay local.
+
+A bound policy supplies explicit builder options, so it overrides QueryClient defaults. Call-site
+options override the bound policy. Omit a field to inherit it; use `staleTime: 0` or `retry: false`
+to replace an inherited setting.
 
-The ordinary and metadata views have separate keys. Configure global or prefix `queryKeyHashFn`
-on QueryClient before using the cache, and keep it stable for the cache owner's lifetime. Generated
-options retain their own query function even if a prefix registers another one. Builders reject
-per-call `queryHash` and `queryKeyHashFn` because native key-only reads and writes must resolve the
-same entry.
+## Bind mutation invalidation
 
-Streams also reject a default `queryHash` that differs from the configured key hasher's result.
-Changing hash defaults while matching entries remain cached can make stream execution reject
-with `UnsupportedQueryHash`. Retire the old cache before changing its hash policy.
+Import `withMutationPolicy` from `effect-api-query`. Seed the returned user and invalidate affected
+reads once for every use of the creation builder:
 
-Use the generated exact `queryKey(input)` or `metadataKey(input)` with native `getQueryData` and
-`setQueryData`. Their data tags preserve the unselected query data type: selecting a name changes
-the observer result, while a native write still supplies the complete user. A fresh native write
-is visible to observers and subsequent imperative reads without another client execution.
+```ts
+const createUserOptions = withMutationPolicy(rpc.users.create, {
+  onSuccess: async (created) => {
+    queryClient.setQueryData(rpc.users.get.queryKey({ id: created.id }), created)
+    await queryClient.invalidateQueries({ queryKey: rpc.users.key() })
+  },
+})
+```
 
-Fetched metadata follows native sharing defaults, while selected results and later manual writes
-use explicit per-call policy or standard deep sharing. See
-[Buffered metadata](/effect-api-query/reference/http-builders/#buffered-metadata) for immutable
-snapshot and application-owned data rules.
+Shared callbacks infer data, variables, and execution errors. `MutationPolicy<Leaf>` can annotate a
+reusable object. Its optimistic result is `unknown`: supply `onMutate` at each call site to infer
+that result in local callbacks. Here `reportCreationFailure` is the application's failure notifier:
 
-An imperative `queryClient.query(newOptions)` hit on fresh cached data retains existing Query
-options. Install a changed sharing policy through an observer or actual fetch before relying
-on it for later manual writes.
+```ts
+const createUser = createUserOptions({
+  onMutate: (variables) => ({ submittedName: variables.name }),
+  onError: (error, _variables, context) => {
+    reportCreationFailure(context?.submittedName, error)
+  },
+})
+```
 
-Keep shared policies on QueryClient and operation-specific selection, input, and typed error
-callbacks on the generated builders.
+A call-site callback replaces the corresponding shared callback. Compose callbacks explicitly
+when both must run. The [complete example](https://github.com/ueberBrot/effect-api-query/blob/main/tests/types/docs-policies.ts)
+includes ready-client types and the imports used here.

+description: Acquire a ready client and use generated options with native React Query hooks.
 ---
 
-Use the utility tree created in the application's client module. Import `useQuery`,
-`useMutation`, `useSuspenseQuery`, and `useQueryClient` from `@tanstack/react-query`.
-The application supplies its Query provider and exposes `rpcQuery` through context or props.
-
-## Read in a component
-
-Inside an existing component:
-
-```ts
-const users = useQuery(rpcQuery.users.list.queryOptions())
-const user = useQuery(rpcQuery.users.get.queryOptions({ input: { id: 1 } }))
-```
-
-Payload-bearing RPC reads take constructor input. Pass native options such as `select`,
-`staleTime`, or `retry` to the builder; `select` changes observer data, not the cached value.
-
-## Write and refresh
-
-In the same component, create the mutation with an explicit invalidation policy:
-
-```ts
-const queryClient = useQueryClient()
-const removeUser = useMutation(
-  rpcQuery.users.delete.mutationOptions({
-    onSuccess: () => queryClient.invalidateQueries({ queryKey: rpcQuery.users.key() }),
-  }),
+Pass generated options directly to React Query's native hooks. Build the utility tree once for
+its ready client and cache owner. Rebuild options when component input changes; the builders
+capture plain input for that execution.
+
+## Acquire and mount the client
+
+Create a small client module and mount it once from your application entry point.
+This read-only example requires React, React DOM, `@tanstack/react-query`, Effect, and
+`effect-api-query`. The server must implement the shared contract below: `GET /users/:id`
+returns `{ id: number, name: string }`.
+
+### Contract and ready client
+
+Place this code in `users-app.tsx`. Move `usersApi` to your shared contract module when connecting
+it to a real server. `startUsersApplication` acquires the ready HTTP API client and keeps one runtime
+and QueryClient alive until `dispose` runs.
+
+```tsx
+import { QueryClient, QueryClientProvider, useQuery } from '@tanstack/react-query'
+import { ManagedRuntime, Schema } from 'effect'
+import { createHttpApiQueryUtils } from 'effect-api-query'
+import type { RunPromiseExit } from 'effect-api-query'
+import { FetchHttpClient } from 'effect/http'
+import { HttpApi, HttpApiClient, HttpApiEndpoint, HttpApiGroup } from 'effect/http-api'
+import { createRoot } from 'react-dom/client'
+
+const usersApi = HttpApi.make('users-api').add(
+  HttpApiGroup.make('users').add(
+    HttpApiEndpoint.get('get', '/users/:id', {
+      params: { id: Schema.Int },
+      success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+    }),
+  ),
 )
-```
-
-In its event handler, supply that execution's variables:
 
-```ts
-removeUser.mutate({ id: userId })
+const startUsersApplication = async (baseUrl: string) => {
+  const runtime = ManagedRuntime.make(FetchHttpClient.layer)
+  const running = new Set<Promise<unknown>>()
+  const runPromiseExit: RunPromiseExit = (effect, options) => {
+    const pending = runtime.runPromiseExit(effect, options)
+    running.add(pending)
+    void pending.then(
+      () => running.delete(pending),
+      () => running.delete(pending),
+    )
+    return pending
+  }
+  try {
+    const client = await runtime.runPromise(HttpApiClient.make(usersApi, { baseUrl }))
+    const queryClient = new QueryClient()
+    const http = createHttpApiQueryUtils(usersApi, {
+      client,
+      keyPrefix: ['users-app'],
+      runPromiseExit,
+    })
+    return {
+      http,
+      queryClient,
+      dispose: async () => {
+        try {
+          await queryClient.cancelQueries()
+        } finally {
+          try {
+            await Promise.allSettled([...running])
+          } finally {
+            queryClient.clear()
+            await runtime.dispose()
+          }
+        }
+      },
+    }
+  } catch (error) {
+    await runtime.dispose()
+    throw error
+  }
+}
 ```
 
-Writes do not automatically refresh reads. Choose the affected generated keys in the application.
+The supplied runner forwards TanStack's abort options and tracks in-flight reads. After cancellation,
+disposal waits for their Effect finalizers before releasing the runtime. Client acquisition finishes
+before React renders. Acquisition failures also dispose the runtime.
+
+### Component and provider
+
+Continue in the same module. The component receives the ready utility tree through props;
+`QueryClientProvider` exposes the matching cache to React Query.
+
+```tsx
+type UsersApplication = Awaited<ReturnType<typeof startUsersApplication>>
+
+const User = ({ application }: { readonly application: UsersApplication }) => {
+  const user = useQuery(application.http.users.get.queryOptions({ input: { params: { id: 1 } } }))
+  if (user.isPending) {
+    return <p>Loading user…</p>
+  }
+  if (user.isError) {
+    return <p role="alert">Could not load the user.</p>
+  }
+  return <h1>{user.data.name}</h1>
+}
+
+export const mountUsersApplication = async (element: HTMLElement, baseUrl: string) => {
+  const application = await startUsersApplication(baseUrl)
+  const root = createRoot(element)
+  root.render(
+    <QueryClientProvider client={application.queryClient}>
+      <User application={application} />
+    </QueryClientProvider>,
+  )
+  return async () => {
+    root.unmount()
+    await application.dispose()
+  }
+}
+```
 
-## Observe a stream
+### Application entry point
 
-Use ordinary query hooks inside the component for either cached representation:
+In `main.tsx`, mount into the root element supplied by your HTML page. Replace the base URL with
+your server's URL.
 
 ```ts
-const events = useQuery(rpcQuery.events.watch.streamedOptions())
-const latestEvent = useQuery(rpcQuery.events.watch.liveOptions())
-```
+import { mountUsersApplication } from './users-app.tsx'
 
-`useSuspenseQuery` also accepts these options. Streams expose data while fetching continues;
-see [Choose Stream History](/effect-api-query/guides/choose-stream-history/) for retention policy.
+const element = document.getElementById('root')
+if (element === null) {
+  throw new Error('Missing application root element')
+}
 
-## Use an HTTP endpoint
-
-The same hooks accept the complete decoded request:
-
-```ts
-const user = useQuery(
-  http.users.get.queryOptions({ input: { params: { id: 1 }, query: { locale: 'en' } } }),
-)
+export const stopUsers = await mountUsersApplication(element, 'http://localhost:3000')
 ```

-[Streaming](/effect-api-query/guides/streaming/), and
-[HTTP Requests and Uploads](/effect-api-query/guides/http-queries-and-mutations/).
-Builders own their key/function fields; configure hashing through
-QueryClient defaults. [RPC Builders](/effect-api-query/reference/generated-builders/) and
-[HTTP Builders](/effect-api-query/reference/http-builders/) describe the precise option contracts.

-For complete components and resource setup, use the [Vite React example](/effect-api-query/examples/):
-[queries](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/components/sections/queries-section.tsx),
-[mutations](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/components/sections/mutations-section.tsx),
-and [application ownership](https://github.com/ueberBrot/effect-api-query/blob/main/examples/vite-react/src/lib/application.ts).
+The host calls and awaits `stopUsers()` when tearing down this application;
+it unmounts React, cancels outstanding reads, awaits their local finalizers, clears the cache,
+and disposes the runtime.
+A browser's unload event cannot guarantee that async cleanup finishes.
+
+This example has one buffered read. Before adding open streams or concurrent writes, use
+[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/) to await their cleanup and settlement.
+For RPC, replace client acquisition with the Scope and protocol in
+[RPC Quick Start](/effect-api-query/getting-started/quick-start/) and pass the resulting RPC utility
+tree to the component. The provider and React hooks stay the same.
+
+## Choose the native hook
+
+The provider and component above use a buffered HTTP query. RPC uses the same hooks with its
+[constructor input](/effect-api-query/concepts/data-normalization/#query-stable-rpc-payloads);
+HTTP takes [decoded request input](/effect-api-query/concepts/data-normalization/#decoded-http-inputs).

+
+Pass `select`, `staleTime`, retry policy, and other native options through the builder.
+`select` changes observer data while the cache retains the generated view's query data.

+Use [Defaults and Policies](/effect-api-query/guides/query-defaults/) to bind an endpoint-aware
+policy once, then reuse it in components, imperative queries, or route loaders. A call-site
+projection or callback keeps its native inference.
+
+For writes, pass generated mutation options to `useMutation` and supply variables through
+`mutate`. Choose the affected generated keys in the application: writes do not invalidate reads
+automatically. Use [Cache Keys and Filters](/effect-api-query/guides/cache-filters/) for broad or exact
+invalidation and [Optimistic Updates](/effect-api-query/guides/optimistic-writes/) for response seeding,
+rollback, and overlapping writes.
+
+## Streams and Suspense
+
+Ordinary hooks can show stream data while fetching continues. Choose
+[history retention](/effect-api-query/guides/choose-stream-history/) for accumulated views and keep
+clients alive until local iterator finalizers finish.
+
+TanStack documents that cancellation does not work with its Suspense hooks. Use ordinary query
+hooks when cancelling reads or stopping open stream work is part of the screen's lifecycle.
+For buffered reads with Suspense, use
+[Suspense and Error Recovery](/effect-api-query/guides/suspense-and-recovery/) for reset/retry,
+cached-data refetch failures, and independent loading with `useSuspenseQueries`.
+
+For router loaders and server rendering, continue with
+[Router and Start](/effect-api-query/guides/tanstack-start/).
+The [Vite React example](/effect-api-query/examples/#run-vite-react) is a complete application with
+reads, writes, streams, private cache owners, and resource disposal.

 title: Retry Queries
-description: Choose bounded retries by inspecting typed Effect failures and native Query options.
+description: Reuse bounded read policies with typed Effect failures and native Query options.
 ---
 
-Set an explicit retry policy for an idempotent read. The callbacks below allow two retries after
-an initial failure: at most three client executions. They retry a declared `RetryLater` or an HTTP
-transport failure, and stop for `NotFound`, `AuthenticationRequired`, Schema failures, defects,
-interruptions, and rejected runners.
+Bind a retry policy once with `withQueryPolicy`, then call the returned options builder wherever
+you need that read. Each call keeps native `select`, input, and initial-data inference. Call-site
+options replace matching defaults.
 
-## Inspect the typed failure
+The policy below permits two retries after the initial failure: at most three executions. It
+allows a declared `RetryLater` or an application-approved transport failure. Use it for idempotent
+reads whose transport does not already own retries.
 
-Use the error union declared by your contract and the native builder's inferred callback types.
-Import `Cause` and `Result` from `effect`, adapter guards from `effect-api-query`, and
-`HttpClientError` from `effect/http`. The
-[complete typed recipe](https://github.com/ueberBrot/effect-api-query/blob/main/tests/types/docs-retry.ts)
-includes `RetryLater`, `NotFound`, authentication errors and both ready-client factories.
+## Share the decision and delay
 
-### RPC retry callback
-
-In the query-options module, use these statements inside the `retry: (failureCount, error) => { ... }`
-callback passed to `rpc.profile.read.queryOptions`. This example allows only an HTTP transport
-failure or its declared `RetryLater`:
+Import `Cause`, `Result`, and `Schema` from `effect`. Define `RetryLater` with a finite
+`retryAfterMs` field in your contract, then reuse this application helper for RPC and HTTP:
 
 ```ts
-if (!isEffectRpcQueryError(error) || failureCount >= 2) {
-  return false
-}
-if (Cause.hasDies(error.cause) || Cause.hasInterrupts(error.cause)) {
-  return false
-}
-const failure = Cause.findError(error.cause)
-if (Result.isFailure(failure) || error.cause.reasons.length !== 1) {
-  return false
-}
-switch (failure.success._tag) {
-  case 'RetryLater':
-    return true
-  case 'RpcClientError':
+const retryPolicy = <Error, Failure>(
+  causeOf: (error: Error) => Cause.Cause<Failure> | undefined,
+  isTransient: (failure: Failure) => boolean,
+) => ({
+  retry: (failureCount: number, error: Error) => {
+    const cause = causeOf(error)
+    if (
+      !cause ||
+      failureCount >= 2 ||
+      Cause.hasDies(cause) ||
+      Cause.hasInterrupts(cause) ||
+      cause.reasons.length !== 1
+    ) {
+      return false
+    }
+    const failure = Cause.findError(cause)
     return (
-      failure.success.reason._tag === 'HttpError' &&
-      failure.success.reason.kind === 'TransportError'
+      Result.isSuccess(failure) &&
+      (Schema.is(RetryLater)(failure.success) || isTransient(failure.success))
     )
-  default:
-    return false
-}
+  },
+  retryDelay: (attemptIndex: number, error: Error) => {
+    const cause = causeOf(error)
+    if (cause) {
+      const failure = Cause.findError(cause)
+      if (Result.isSuccess(failure) && Schema.is(RetryLater)(failure.success)) {
+        return Math.min(30_000, Math.max(0, failure.success.retryAfterMs))
+      }
+    }
+    return Math.min(1_000 * 2 ** attemptIndex, 30_000)
+  },
+})
 ```
 
-### HTTP retry callback
+This rejects defects, interruptions, and Causes with multiple reasons. `Cause.findError` returns
+a `Result`; the successful value retains the typed failure union. Schema refinement also handles
+unknown values safely. The adapter guard rejects custom runner failures that pass through unchanged.
+
+## Bind a typed RPC policy
 
-For `http.profile.read.queryOptions`, the callback has the same guard stages but a different
-transport-error union. Its `retry` callback body is:
+Import `withQueryPolicy`, `isEffectRpcQueryError`, and the type `InferQueryError` from
+`effect-api-query`, plus `RpcClientError` from `effect/rpc`. After acquiring your ready client and
+creating `rpc`, bind the profile read:
 
 ```ts
-if (!isEffectHttpApiQueryError(error) || failureCount >= 2) {
-  return false
-}
-if (Cause.hasDies(error.cause) || Cause.hasInterrupts(error.cause)) {
-  return false
-}
-const failure = Cause.findError(error.cause)
-if (Result.isFailure(failure) || error.cause.reasons.length !== 1) {
-  return false
-}
-switch (failure.success._tag) {
-  case 'RetryLater':
-    return true
-  case 'HttpClientError':
-    return (
-      HttpClientError.isHttpClientError(failure.success) &&
-      failure.success.reason._tag === 'TransportError'
-    )
-  default:
-    return false
-}
+type Error = InferQueryError<typeof rpc.profile.read>
+const read = withQueryPolicy(
+  rpc.profile.read,
+  'query',
+  retryPolicy(
+    (error: Error) => (isEffectRpcQueryError(error) ? error.cause : undefined),
+    (failure) =>
+      Schema.is(RpcClientError.RpcClientError)(failure) &&
+      failure.reason._tag === 'HttpError' &&
+      failure.reason.kind === 'TransportError',
+  ),
+)
+return read()
 ```
 
-### Retry delay callback
+This application allows only RPC's HTTP transport failures. Socket and worker reconnect policy
+belongs to the application that owns those transports.
+
+## Bind the same decision to HTTP
 
-In the RPC builder's `retryDelay: (attemptIndex, error) => { ... }` body:
+Import `isEffectHttpApiQueryError` from `effect-api-query` and `HttpClientError` from `effect/http`. Keep the shared retry
+logic and supply HTTP's transport classifier:
 
 ```ts
-if (isEffectRpcQueryError(error)) {
-  const failure = Cause.findError(error.cause)
-  if (Result.isSuccess(failure) && failure.success._tag === 'RetryLater') {
-    return Math.min(30_000, Math.max(0, failure.success.retryAfterMs))
-  }
-}
-return Math.min(1_000 * 2 ** attemptIndex, 30_000)
+type Error = InferQueryError<typeof http.profile.read>
+const read = withQueryPolicy(
+  http.profile.read,
+  'query',
+  retryPolicy(
+    (error: Error) => (isEffectHttpApiQueryError(error) ? error.cause : undefined),
+    (failure) =>
+      HttpClientError.isHttpClientError(failure) && failure.reason._tag === 'TransportError',
+  ),
+)
+return read()
 ```
 
-The complete recipe applies the equivalent guarded delay to HTTP. These callbacks are application
-policy for idempotent reads, not a package retry policy.
+Encoding, decoding, response, `NotFound`, and authentication failures receive no retry. Restore an
+expired session before invalidating its affected queries.
 
-`Cause.findError` returns a `Result`; after `Result.isSuccess`, `success` retains the declared
-error union. It extracts the first typed failure. Check defects and interruptions first, and
-inspect all `cause.reasons` when several failures are meaningful to your policy. This example
-rejects every Cause with more than one reason, including a retryable failure combined with a defect,
-interruption, or another typed failure.
-
-The runtime guard also rejects a custom runner's original rejection. A runner rejection produces
-no failed Effect `Exit`, so it need not have the statically declared execution-error shape. Keep
-this guard in retry and retry-delay callbacks that can receive custom runner failures.
-
-An HTTP `TransportError` is safe to retry here because this operation is an idempotent read. Other
-`HttpClientError` reasons include encoding, decoding, and response failures. An RPC
-`RpcClientError` can contain HTTP, socket, worker, or protocol failures; the RPC policy above
-explicitly allows only its HTTP transport reason. Choose socket/worker reconnection policy in the
-application that owns that transport. Handle expired authentication by restoring the application
-session and invalidating affected queries, instead of repeatedly sending the same credentials.
-
-`retryDelay` receives the zero-based attempt index and the same typed error. It returns milliseconds,
-not an Effect or Promise. Query Core can evaluate it even for a terminal failure, so keep it pure.
-The example bounds server-provided delays and caps exponential backoff at 30 seconds.
+The [complete compiled recipe](https://github.com/ueberBrot/effect-api-query/blob/main/tests/types/docs-retry.ts)
+contains the contracts and both ready-client factories. See [Query Defaults](/effect-api-query/guides/query-defaults/)

-options inside a `try` block when input or custom encoders may fail, then pass the successful options
-to Query Core. These errors occur before a query is registered and never enter execution retry.
-For an infinite query, the later page-input mapper executes during fetching; errors it throws reach
-TanStack unchanged and need an explicit non-retry decision. Mutations encode input inside the
-ready client's Effect, so their encoding failures use the execution Cause.
-
-Keep QueryClient hashing stable while entries remain cached. A stream that encounters a matching
-entry under an incompatible hash policy rejects with configuration code `UnsupportedQueryHash`.
-Retries cannot repair that policy; retire the old cache before using a different hash function.

+title: Suspense and Error Recovery
+description: Reset failed Suspense queries, preserve cached data, and start independent reads together.
+---
+
+Use TanStack's native Suspense hooks inside an existing `QueryClientProvider`, such as the
+[React client setup](/effect-api-query/guides/react-query/#acquire-and-mount-the-client).
+`useSuspenseQuery` provides defined data after its loading boundary resolves. An initial failure
+reaches the nearest React error boundary after retries finish.
+
+TanStack documents that cancellation does not work with `useSuspenseQuery`,
+`useSuspenseQueries`, or `useSuspenseInfiniteQuery`. Choose `useQuery` or `useInfiniteQuery`
+when your screen depends on cancellation, including stopping open stream work when observation
+ends. Generated signal forwarding does not remove this native hook limitation.
+See [TanStack query cancellation](https://tanstack.com/query/latest/docs/framework/react/guides/query-cancellation#limitations).
+
+## Define a displayable failure
+
+This complete recipe uses a ready client for the following RPC contract. The application chooses
+which declared messages are suitable for users. Error boundaries receive `unknown`; recognize the
+execution wrapper and validate its Cause failure with Schema before reading a domain message.
+Transport failures, defects, and unexpected errors use a generic fallback.
+
+```tsx
+import {
+  QueryErrorResetBoundary,
+  useSuspenseQueries,
+  useSuspenseQuery,
+} from '@tanstack/react-query'
+import { Cause, Result, Schema } from 'effect'
+import { createRpcQueryUtils, isEffectRpcQueryError } from 'effect-api-query'
+import type { InferQueryData, InferQueryError } from 'effect-api-query'
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+import { Component, Suspense } from 'react'
+import type { ReactNode } from 'react'
+
+export class UserUnavailable extends Schema.TaggedError<UserUnavailable>()('UserUnavailable', {
+  message: Schema.String,
+}) {}
+
+export const suspenseGroup = RpcGroup.make(
+  Rpc.make('users.get', {
+    payload: { id: Schema.Int },
+    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+    error: UserUnavailable,
+  }),
+)
+
+export const makeSuspenseQueries = <E,>(
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof suspenseGroup>, E>,
+) =>
+  createRpcQueryUtils<typeof suspenseGroup, readonly ['suspense-users'], E>(suspenseGroup, {
+    client,
+    keyPrefix: ['suspense-users'],
+  })
+
+export type Queries<E> = ReturnType<typeof makeSuspenseQueries<E>>
+
+export const failureMessage = (error: unknown): string => {
+  if (isEffectRpcQueryError(error)) {

+      Schema.is(UserUnavailable)(failure.success)
+    ) {
+      return failure.success.message
+    }
+  }
+  return 'The request failed. Please try again.'
+}
+```
+
+## Reset both boundaries
+
+React owns the error boundary below. `QueryErrorResetBoundary` supplies its `onReset` callback.
+The retry button first resets TanStack's failed-query boundary, then clears React's error state
+so the component can mount and fetch again. This uses React's built-in Component class and
+requires no additional error-boundary package.
+
+```tsx
+interface BoundaryProps {
+  readonly children: ReactNode
+  readonly onReset: () => void
+}
+
+interface BoundaryState {
+  readonly failed: boolean
+  readonly error: unknown
+}
+
+class RequestErrorBoundary extends Component<BoundaryProps, BoundaryState> {
+  override state: BoundaryState = { failed: false, error: undefined }
+
+  static getDerivedStateFromError(error: unknown): BoundaryState {
+    return { failed: true, error }
+  }
+
+  reset = () => {
+    this.props.onReset()
+    this.setState({ failed: false, error: undefined })
+  }
+
+  override render() {
+    if (this.state.failed) {
+      return (
+        <div role="alert">
+          <p>{failureMessage(this.state.error)}</p>
+          <button type="button" onClick={this.reset}>
+            Try again
+          </button>
+        </div>
+      )
+    }
+    return this.props.children
+  }
+}
+```
+
+## Preserve data after a failed refresh
+
+Use both boundaries around the component. This example disables automatic retries so the user
+can choose when to retry. It retains native Suspense behavior: a failed initial load reaches the
+boundary; a failed background refetch keeps cached data visible and displays an inline error.
+The Refresh button retries that background request.
+
+```tsx
+const UserDetails = <E,>({ rpc }: { readonly rpc: Queries<E> }) => {
+  const user = useSuspenseQuery(
+    rpc.users.get.queryOptions({ input: { id: 1 }, retry: false, staleTime: 30_000 }),
+  )
+  return (
+    <>
+      <h2>{user.data.name}</h2>
+      {user.error !== null && !user.isFetching ? (
+        <p role="alert">{failureMessage(user.error)}</p>
+      ) : null}
+      <button type="button" onClick={() => void user.refetch()} disabled={user.isFetching}>
+        Refresh
+      </button>
+    </>
+  )
+}
+
+export const UserScreen = <E,>({ rpc }: { readonly rpc: Queries<E> }) => (
+  <QueryErrorResetBoundary>
+    {({ reset }) => (
+      <RequestErrorBoundary onReset={reset}>
+        <Suspense fallback={<p>Loading user…</p>}>
+          <UserDetails rpc={rpc} />
+        </Suspense>
+      </RequestErrorBoundary>
+    )}
+  </QueryErrorResetBoundary>
+)
+```
+
+Suspense throws query failures by default only when cached data is absent. If your application
+must route failed refetches to the error boundary too, throw the observer error from the component
+after fetching stops. Handle intentional `null` query data explicitly when using a void contract.
+See [TanStack Suspense recovery](https://tanstack.com/query/latest/docs/framework/react/guides/suspense#resetting-error-boundaries).
+
+## Start independent reads together
+
+Sequential `useSuspenseQuery` calls in one component can create a waterfall: the first hook
+suspends before the later hook runs. Pass independent requests to `useSuspenseQueries` instead.
+With generated options, explicit query descriptors retain the data and error types through
+TanStack's parallel-hook overloads. Derive these descriptors from the leaf so changes to its
+contract update every consumer.
+
+```tsx
+export const TwoUsers = <E,>({ rpc }: { readonly rpc: Queries<E> }) => {
+  type UserQuery = {
+    queryFnData: InferQueryData<typeof rpc.users.get>
+    error: InferQueryError<typeof rpc.users.get>
+  }
+  const [ada, grace] = useSuspenseQueries<[UserQuery, UserQuery]>({
+    queries: [
+      rpc.users.get.queryOptions({ input: { id: 1 }, retry: false, staleTime: 30_000 }),
+      rpc.users.get.queryOptions({ input: { id: 2 }, retry: false, staleTime: 30_000 }),
+    ],
+  })
+  return (
+    <p>
+      {ada.data.name} and {grace.data.name}
+    </p>
+  )
+}
+```
+
+Render `TwoUsers` inside the same reset and Suspense boundaries. Both reads start together.
+Choose a `staleTime` long enough that an earlier completed query remains fresh while the other
+finishes; otherwise mounting after Suspense resolves can cause an immediate refetch.

+title: Trace Stream Consumption
+description: Keep an application span open through HTTP SSE pulls and asynchronous iterator cleanup.
+---
+
+Configure telemetry in the application's runtime and instrument the stream that a ready client
+returns. A span around the `runPromiseExit` creation Effect ends when it returns the iterable.
+Actual stream pulls happen later; they need their own span.
+
+## Attach a span to the decoded stream
+
+This client module declares a string SSE feed at `GET /events`. Its response transformation wraps
+only decoded streams and passes other values through. HttpApiClient applies that transformation
+before response-mode wrapping, so the client retains its native request options and response
+contract. Keep header-wrapped stream schemas intact if your API declares them; this simple feed
+has no decoded header wrapper.
+
+```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Effect, Layer, ManagedRuntime, Schema, Stream, Tracer } from 'effect'
+import { createHttpApiQueryUtils, fetchStreamSnapshot } from 'effect-api-query'
+import type { RunPromiseExit } from 'effect-api-query'
+import { FetchHttpClient } from 'effect/http'
+import {
+  HttpApi,
+  HttpApiClient,
+  HttpApiEndpoint,
+  HttpApiGroup,
+  HttpApiSchema,
+} from 'effect/http-api'
+import { OtlpSerialization, OtlpTracer } from 'effect/observability'
+
+const feedApi = HttpApi.make('feed-api').add(
+  HttpApiGroup.make('events').add(
+    HttpApiEndpoint.get('watch', '/events', {
+      success: HttpApiSchema.StreamSse({ data: Schema.String }),
+    }),
+  ),
+)
+
+export const traceFeed = <A, E, R>(source: Stream.Stream<A, E, R>) =>
+  Stream.unwrap(
+    Effect.gen(function* () {
+      const span = yield* Effect.makeSpanScoped('events.watch.consume', {
+        attributes: { 'api.id': 'feed-api', endpoint: 'watch' },
+      })
+      return source.pipe(
+        Stream.tap(() => Effect.sync(() => span.attribute('feed.received', true))),
+        Stream.ensuring(Effect.sync(() => span.attribute('feed.cleanup', true))),
+        Stream.provideService(Tracer.ParentSpan, span),
+      )
+    }),
+  )
+
+const traceDecodedResponse = (effect: Effect.Effect<unknown, unknown, unknown>) =>
+  effect.pipe(Effect.map((value) => (Stream.isStream(value) ? traceFeed(value) : value)))
+```
+
+`Stream.unwrap` acquires the scoped span when consumption begins. Providing its ParentSpan
+makes nested pull work a child of that span. The finalizer updates the captured span directly,
+so it does not depend on a pull fiber's current-span context. The span closes after local stream
+finalizers finish, including asynchronous cancellation cleanup.
+
+The attributes identify the declared API and endpoint. The example records receipt and cleanup
+without exporting emitted data, request input, or credentials.
+
+## Supply the runtime and await cleanup
+
+Use Effect's OTLP tracer with an exporter URL, such as your collector's `/v1/traces` endpoint.
+This function configures a runtime, acquires the ready client, injects a signal-aware runner,
+and captures one live value. Its snapshot helper stops the iterator and awaits local cleanup
+before the runtime is disposed.
+
+```ts
+const captureTracedFeed = async (baseUrl: string, collectorUrl: string, signal: AbortSignal) => {
+  const telemetry = OtlpTracer.layer({
+    url: collectorUrl,
+    resource: { serviceName: 'users-browser' },
+  }).pipe(Layer.provide(OtlpSerialization.layerJson), Layer.provide(FetchHttpClient.layer))
+  const runtime = ManagedRuntime.make(Layer.merge(FetchHttpClient.layer, telemetry))
+  const queryClient = new QueryClient()
+  try {
+    const client = await runtime.runPromise(
+      HttpApiClient.make(feedApi, { baseUrl, transformResponse: traceDecodedResponse }),
+    )
+    const runPromiseExit: RunPromiseExit = (effect, options) =>
+      runtime.runPromiseExit(effect, options)
+    const http = createHttpApiQueryUtils(feedApi, {
+      client,
+      keyPrefix: ['feed-app'],
+      runPromiseExit,
+    })
+    return await fetchStreamSnapshot(queryClient, http.events.watch.liveOptions({ retry: false }), {
+      signal,
+      timeoutMs: 5_000,
+    })
+  } finally {
+    try {
+      await queryClient.cancelQueries()
+    } finally {
+      queryClient.clear()
+      await runtime.dispose()
+    }
+  }
+}
+```
+
+Call `captureTracedFeed` with your API base URL, collector URL, and an application-owned
+AbortSignal. A browser collector needs to accept that browser's requests. The telemetry layer
+and span policy belong to the application; the package does not install an exporter or log by default.
+The same response transformation covers accumulated and live HTTP SSE views.
+
+For RPC streams, instrument the stream in the application's client/transport integration while
+preserving the flat client's request options and queue modes. Effect RPC also creates native
+client spans when tracing is enabled. Configure those spans and telemetry during client
+acquisition; wrapping only iterable creation still does not cover later consumption.
+
+For an open browser feed, keep the runtime alive until the local stream finalizer signals completion.
+Native `cancelQueries` can settle before asynchronous cleanup finishes. Use
+[Stream Snapshots](/effect-api-query/guides/stream-snapshots/) for finite capture and
+[Client Lifecycle](/effect-api-query/concepts/client-lifecycle/) for long-lived ownership.

+
+These pages explain how generated options participate in each native API. Use the framework's
+own TanStack documentation for its provider, rendering, and reactive primitives.
+
+## Rebuild options at the reactive boundary
+
+Acquire the ready client and create its utility tree once for a cache owner. Call a builder inside
+React render or the other framework's computed value/accessor when its input depends on reactive
+state. Passing one previously built options object keeps the captured request attached to its
+original input.
+
+Keep [captured inputs unchanged](/effect-api-query/concepts/data-normalization/#keep-captured-inputs-unchanged)
+while options can execute. The immutable key does not freeze arbitrary request values.
+A new request needs new input and options. Mutation variables belong to each execution;
+rebuild mutation options only when their callbacks or settings depend on reactive state.
+
+## Own the cache and client lifetime
+
+Provide the matching QueryClient through the native framework's provider or router context.
+Match its Query wrapper to the application's Query Core version and use a compiler supported by
+the framework tooling. The [compatibility reference](/effect-api-query/reference/compatibility-and-limits/)
+records the tested combinations.
+
+A changed input or removed component detaches its observer. An abort-aware open stream cancels
+when its last ordinary observer leaves; another observer can keep it active. TanStack's Suspense
+hooks retain their documented cancellation limitation. Transport interruption depends on the
+ready client.
+
+Stop consumers, cancel queries, await local finalizers and accepted mutations, then clear the cache
+and release the client and runtime. Follow [Client Lifecycle](/effect-api-query/concepts/client-lifecycle/)
+for disposal and [Switch Cache Owners](/effect-api-query/guides/switch-cache-owners/) when identity changes.
+Native cancellation can settle before asynchronous iterator cleanup finishes.
+
+## Server rendering and hydration
+
+A server request owns a fresh QueryClient and request-specific clients. The browser owns separate
+resources, while equivalent inputs and prefixes address equivalent cache entries. Choose codecs
+that preserve the decoded values across dehydration, hydration, and later client refetches.
+
+Use [Hydrate Query Data](/effect-api-query/guides/hydrate-unary-data/) for DTOs or Schema classes,
+[Hydrate Query Views](/effect-api-query/guides/hydrate-query-views/) for pages, metadata, and stream
+representations, and [Stream Snapshots](/effect-api-query/guides/stream-snapshots/) to settle a finite
+capture and local cleanup before disposing a request.
+
+## Configure the client and host
+
+Applications configure transport, authentication, middleware, runtime services, and telemetry
+before passing a ready client to a factory. See
+[WebSocket Clients](/effect-api-query/guides/websocket-clients/),
+[Browser and Worker Hosts](/effect-api-query/reference/browser-and-worker-hosts/), and
+[Stream Tracing](/effect-api-query/guides/trace-streams/).
+[External HTTP Clients](/effect-api-query/reference/external-http-clients/) explains encoded OpenAPI
+interop; those Promise clients do not replace the ready Effect HttpApiClient accepted by the factory.
+
+For complete hosts and applications, [run the examples](/effect-api-query/examples/).

+
+`viewPrefix(leaf, view)` returns an immutable ordinary key for every input and stream policy of a
+supported leaf view. Pass it to native query filters or `setQueryDefaults`. It carries no DataTag;
+broad cache reads remain `unknown`. Use a concrete generated key for typed exact cache access.

+## Reuse typed policies
+
+`withQueryPolicy(leaf, view, defaults)` and `withMutationPolicy(leaf, defaults)` return the leaf's

+objects. Inputs, projections, initial data, pagination setup, and adapter controls remain local.
+Shared mutation callbacks have an unknown optimistic result; supply `onMutate` and callbacks that
+use its result at the call site. See [Defaults and Policies](/effect-api-query/guides/query-defaults/).

+title: Type Inference
+description: Derive operation inputs, cached data, mutation results, and failures from generated leaves.
+---
+
+Import these types from `effect-api-query` and apply them to a generated leaf:
+
+| Type                          | Result                                                    |
+| ----------------------------- | --------------------------------------------------------- |
+| `InferInput<Leaf>`            | The accepted operation input                              |
+| `InferQueryData<Leaf, View>`  | Cached data for a supported query view, before `select`   |
+| `InferQueryError<Leaf, View>` | Execution and package failures carried by that query view |
+| `InferMutationData<Leaf>`     | The successful buffered mutation result                   |
+| `InferMutationError<Leaf>`    | The buffered mutation's execution error                   |
+
+These helpers follow the utility tree's contract and ready-client types. Keep those declaration
+names literal to preserve leaf paths and supported views.
+
+## Operation input
+
+With the utility tree from your client module:
+
+```ts
+const input: InferInput<typeof rpc.users.get> = { id: 1 }
+type UserData = InferQueryData<typeof rpc.users.get>
+type HistoryData = InferQueryData<typeof rpc.diagnostics.stream, 'streamed'>
+type UserError = InferQueryError<typeof rpc.users.get>
+```
+
+RPC input is **payload constructor input**, so fields supplied by constructor defaults may be
+omitted. HTTP input is the **decoded request** with its declared `params`, `query`, `headers`, and
+`payload` containers. Multipart HTTP requests use `FormData` in the payload container. Inputless
+leaves use `void`. `skipToken` disables an options-builder call; it does not change the leaf's
+operation input contract.
+
+## Query views and cached data
+
+Query data and error helpers default to `query`. A streaming leaf needs an explicit `live` or
+`streamed` view. Each leaf constrains `View` to its supported key and option builders:
+
+| Leaf                             | Query views                     |
+| -------------------------------- | ------------------------------- |
+| Unary RPC                        | `query`, `infinite`             |
+| Buffered nonmultipart HTTP       | `query`, `infinite`, `metadata` |
+| RPC stream or supported HTTP SSE | `streamed`, `live`              |
+| Buffered multipart HTTP          | Mutation-only                   |
+
+An unsupported explicit view fails typechecking. Omitting the view on a leaf with no ordinary
+query produces `never`; specify its supported view.
+
+Buffered and live query data normalize top-level successful `undefined` to `null`. Accumulated
+histories preserve each emitted value. Infinite data includes pages and page parameters; metadata
+contains decoded data, status, and headers. See
+[Data Normalization](/effect-api-query/concepts/data-normalization/) for ownership rules.
+
+`InferQueryData` describes cache contents. A native `select` changes the returned value:
+
+```ts
+const selectedOptions = rpc.users.get.queryOptions({
+  input: { id: 1 },
+  select: (value) => value.name,
+})
+const selectedName = await queryClient.query(selectedOptions)
+const cachedUser = queryClient.getQueryData(selectedOptions.queryKey)
+```
+
+Here `selectedName` is a string and `cachedUser` is the decoded user or `undefined`. The generated
+key retains the unselected cache type. Broad prefix/filter reads can contain different views;
+keep those results `unknown` until the application establishes their representation.
+
+Standalone infinite keys, and therefore `InferQueryData<Leaf, 'infinite'>`, use `unknown` for page
+parameters. An `infiniteOptions(...)` result retains the page parameter inferred from that call.
+
+## Mutation results
+
+Infer the write contract separately:
+
+```ts
+type CreateUserInput = InferInput<typeof rpc.users.create>
+type CreatedUser = InferMutationData<typeof rpc.users.create>
+type CreateUserError = InferMutationError<typeof rpc.users.create>
+```
+
+Mutation data preserves the successful decoded value, including `undefined`. Mutation callbacks
+infer variables, data, errors, and their local `onMutate` result through the options builder.
+Use [Defaults and Policies](/effect-api-query/guides/query-defaults/) to reuse typed callbacks while
+preserving that local inference.
+
+## Failures at runtime
+
+Inferred errors describe declared execution and package failures. Execution errors retain the full
+Effect `Cause`. A custom runner rejection or an error thrown by an application callback can pass
+through unchanged; the inferred union does not validate those unknown failures.
+
+Use the package's execution-error guards and refine domain failures before reading their fields.
+See [Handle Failures](/effect-api-query/guides/handle-failures/) and the
+[error reference](/effect-api-query/reference/errors/).

+throw it if the application wants boundary recovery.

 # effect-api-query
 
-Use your native Effect RPC and HttpApi contracts with typed TanStack Query options and semantic cache keys.
-
-Create utilities from your API definition and a ready client, then pass their options directly to
-TanStack Query. Your application controls the client lifetime, cache policies, and framework setup.
+Derive typed TanStack Query options and cache keys from your Effect RPC and HttpApi contracts.
+Pass the generated options to QueryClient or your framework's Query hooks. Inputs and results
+follow the contract; your application controls transport, client lifetime, and cache policy.
 
 ## Install
 
+Install the package and TanStack Query Core:
+
 ```sh
 pnpm add effect-api-query @tanstack/query-core
 ```
 
-With automatic peer installation enabled, pnpm installs the exact Effect version declared by the
-package. Use TypeScript 5.9 or newer with `strict: true`. The package requires ESM and ES2022 support.
-Before upgrading, review [compatibility and stability](https://ueberbrot.github.io/effect-api-query/getting-started/compatibility-and-stability/).
+The package pins one exact Effect 4 release because its RPC and HTTP API modules are unstable.
+With automatic peer installation enabled, pnpm installs that version. Existing applications must
+match it. Use TypeScript 5.9 or newer with `strict: true`, ESM, and ES2022 support. See
+[compatibility and stability](https://ueberbrot.github.io/effect-api-query/getting-started/compatibility-and-stability/).
 
-## Query an RPC
+## RPC
 
-In the application client module, use your existing RPC group, ready flat client and runner:
+Share this contract with your server and acquire a matching **flat RPC client** before calling
+`readUser`. Keep its Scope alive while the client is in use. The
+[RPC quick start](https://ueberbrot.github.io/effect-api-query/getting-started/quick-start/)
+shows acquisition and cleanup.
 
 ```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
 import { createRpcQueryUtils } from 'effect-api-query'
-
-const rpc = createRpcQueryUtils(rpcGroup, {
-  client,
-  keyPrefix: ['my-app'],
-  runPromiseExit,
-})
-```
-
-In a loader or event handler, use the application's QueryClient:
-
-```ts
-const options = rpc.users.get.queryOptions({ input: { id: 1 } })
-const user = await queryClient.query(options)
+import { Rpc, RpcGroup } from 'effect/rpc'
+import type { RpcClient } from 'effect/rpc'
+
+const usersRpc = RpcGroup.make(
+  Rpc.make('users.get', {
+    payload: { id: Schema.Int },
+    success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+  }),
+)
+
+async function readUser(
+  client: RpcClient.RpcClient.Flat<RpcGroup.Rpcs<typeof usersRpc>>,
+  queryClient: QueryClient,
+) {
+  const rpc = createRpcQueryUtils(usersRpc, { client, keyPrefix: ['users-app'] })
+  const user = await queryClient.query(rpc.users.get.queryOptions({ input: { id: 1 } }))
+  return user.name
+}
 ```
 
-Follow the [RPC quick start](https://ueberbrot.github.io/effect-api-query/getting-started/quick-start/)
-for setup and cleanup.
+Dotted tags become nested utility paths: `users.get` becomes `rpc.users.get`. RPC inputs use the
+payload Schema's constructor input.
 
-## Query an HttpApi
+## HTTP
 
-In the application client module, use your existing HttpApi, ready client and runner:
+Share this HttpApi with your server and acquire its **ready HttpApiClient** before calling
+`readUser`. Keep its transport resources alive while the client is in use. The
+[HTTP quick start](https://ueberbrot.github.io/effect-api-query/getting-started/http-quick-start/)
+shows acquisition and cleanup.
 
 ```ts
+import { QueryClient } from '@tanstack/query-core'
+import { Schema } from 'effect'
 import { createHttpApiQueryUtils } from 'effect-api-query'
-
-const http = createHttpApiQueryUtils(api, {
-  client: httpClient,
-  keyPrefix: ['my-app'],
-  runPromiseExit,
-})
+import { HttpApi, HttpApiEndpoint, HttpApiGroup } from 'effect/http-api'
+import type { HttpApiClient } from 'effect/http-api'
+
+const usersApi = HttpApi.make('users-api').add(
+  HttpApiGroup.make('users').add(
+    HttpApiEndpoint.get('get', '/users/:id', {
+      params: { id: Schema.Int },
+      success: Schema.Struct({ id: Schema.Int, name: Schema.String }),
+    }),
+  ),
+)
+
+async function readUser(client: HttpApiClient.ForApi<typeof usersApi>, queryClient: QueryClient) {
+  const http = createHttpApiQueryUtils(usersApi, { client, keyPrefix: ['users-app'] })
+  const user = await queryClient.query(
+    http.users.get.queryOptions({ input: { params: { id: 1 } } }),
+  )
+  return user.name
+}
 ```
 
-In a loader or event handler:
-
-```ts
-const options = http.users.get.queryOptions({
-  input: { params: { id: 1 }, query: { locale: 'en' } },
-})
-const user = await queryClient.query(options)
-```
-
-HTTP accepts decoded request parts; RPC accepts payload constructor input. Follow the
-[HTTP quick start](https://ueberbrot.github.io/effect-api-query/getting-started/http-quick-start/)
-for a complete declaration, client, query, and mutation.
-
-## Choose an operation
-
-| API definition                              | Available operations                               |
-| ------------------------------------------- | -------------------------------------------------- |
-| Unary RPC                                   | Queries, infinite queries, and mutations           |
-| Streaming RPC                               | Accumulated streamed queries and live queries      |
-| Buffered HttpApi endpoint without multipart | Queries, metadata, infinite queries, and mutations |
-| Buffered HttpApi endpoint with multipart    | Mutations with `FormData`                          |
-| Unambiguous HttpApi SSE endpoint            | Accumulated streamed queries and live queries      |
-
-Use the focused guides for [queries](https://ueberbrot.github.io/effect-api-query/guides/queries/),
-[mutations](https://ueberbrot.github.io/effect-api-query/guides/mutations/),
-[pagination](https://ueberbrot.github.io/effect-api-query/guides/pagination/),
-[streaming](https://ueberbrot.github.io/effect-api-query/guides/streaming/), and
-[HTTP metadata](https://ueberbrot.github.io/effect-api-query/guides/http-metadata/).
-
-Both factories generate keys for cache reads, writes, prefetching, and invalidation. Query functions
-forward cancellation to Effect. Mutations use TanStack's normal callbacks; invalidate affected
-queries in your application.
-
-Multipart payloads use explicit `FormData`. Mixed HTTP success modes, raw byte streams and
-streaming multipart requests are omitted; see [feature support](https://ueberbrot.github.io/effect-api-query/getting-started/feature-support/).
+HTTP inputs use decoded `params`, `query`, `headers`, and `payload` containers. Both examples use
+the default Effect runner; provide a signal-aware `runPromiseExit` when execution needs services.
+Choose a `keyPrefix` that identifies your application and any user or tenant that affects its data.
+Keep credentials out of keys.
 
-## Reuse policies and cache keys
+## Capabilities
 
-Bind shared retry, freshness, or mutation callbacks with `withQueryPolicy` and
-`withMutationPolicy`. The returned builders preserve the leaf's input and result types;
-call-site options override the shared defaults. Use `viewPrefix` to target every input
-for one cache view, or a generated concrete key for a typed cache read or write.
+| Contract                                | Generated operations                          |
+| --------------------------------------- | --------------------------------------------- |
+| Unary RPC or buffered nonmultipart HTTP | Query, infinite query, mutation               |
+| Buffered nonmultipart HTTP              | Separate response status/header metadata view |
+| Buffered multipart HTTP                 | Mutation with explicit `FormData`             |
+| RPC stream or unambiguous HTTP SSE      | Accumulated streamed query, live query        |
 
-Follow [defaults and policies](https://ueberbrot.github.io/effect-api-query/guides/query-defaults/)
-and [cache filters](https://ueberbrot.github.io/effect-api-query/guides/cache-filters/).
-The [type inference helpers](https://ueberbrot.github.io/effect-api-query/reference/type-inference/)
-extract a leaf's input, cached data, mutation data, and execution error types.
+Generated keys support cache reads, writes, and invalidation. Queries forward cancellation to
+Effect. Use `withQueryPolicy` and `withMutationPolicy` to share typed defaults. Your application
+invalidates affected queries after mutations. See
+[feature support](https://ueberbrot.github.io/effect-api-query/getting-started/feature-support/)
+for supported contracts and limits.
