erkamyaman · 2026-10-11T21:36:18Z

What and why

Fixes confirmed findings from the audit issues for #344, #345, #346, #350, #351. One commit per issue, each ending with Refs #<n>. The issues stay open for the items listed under Left open.

#344 (components, change detection and defer blocks)

Fixed (11):

Components: picking leaks pointer events to the app (Medium)
Components: SVG component hosts can't be highlighted while picking (Low)
Components: highlight box ignores shadow-root children (Low)
CD: a second start wipes a running recording (Medium)
CD: stale output trigger (Medium)
CD: limits hit silently (Low) (partly)
CD: nested tick replaces the cycle in progress (Low, to confirm)
CD: duplicated types (Low)
Defer: stuck placeholder noise (Medium)
Defer: no runtime @let (Medium, to confirm) (partly)
Defer: unfocusable rows (Low)

Left open (17):

Components: no source location for directives; guessed fallback (Low): Touches three layers (source scan, tree detail, panel) and needs a 'likely' label in the UI. Too big for this batch.
Components: changed values not visible / Show in Signals (Low): New panel feature with UX decisions (flash, cross-page link).
Components improvement: open template file and line: Needs a source-scan change and a new SourceComponent field. Not local.
Components improvement: pick by keyboard: New interaction design. Not a small local change.
Components improvement: Copy as JSON / Copy host path: New panel actions. Needs a product decision on the format.
CD: wrong 'needs Angular 20' message (Low): Needs a new reason field, retry logic and a version fallback across overlay, server, agent tool and panel. Larger than a local fix.
CD: start confirmed without an answer from the page (Low): Needs a wait-for-push handshake in devframe and the panel. Cross-layer.
CD: panel shows less than the agent tool / track $index (Low): The extra panel lists and links are feature work. track $index is deliberate: duplicate-track-keys.test.ts covers two classes with the same name, so track c.name would bring back the duplicate-key warning.
CD improvement: keep recording across a reload: Changes behaviour (sessionStorage per pageId) and needs a product decision.
CD improvement: slow cycle budget limits.cdSlowMs: New config option. That is public API.
Defer: missing hydratedAt (Low): Needs a new 'hydrated before inspection' state shown in the panel and agent text. A product/UX choice.
Defer: silent 500-block cap (Low): Needs a truncated flag through the collector, report shape, server, agent text and panel pill. Cross-layer.
Defer: panel hides data it has (Low): New expandable row detail and badges. Panel feature work.
Defer: clock skew (Low, to confirm): Confirmed (server Date.now() compared with the page's since), but the fix changes the report shape across page, server and tool. Left for a focused change.
Defer: mismatch 'component' is a node name (Low): scanHydration has no ng access. Resolving the owner and adding fields changes the report shape.
Defer: partial block highlight (Low): Needs request-page-highlight to accept several ids, a protocol change.
Defer improvements (badges, force-load action tool, transition timeline, mismatch links, defer blocks in component detail): New features or tools, some depending on phase 3 of 4: a shell you live in #342. Not small or local.

#345 (injectors)

Fixed (7):

Low: Service dependencies skip InjectionTokens
Low: No validation on push-injector-tree
Low: Angular-native overlay keeps a failed push as sent
Low: NativeScript overlay resends the whole tree on keepalive
Low: Zone mode never shown
Low: Hardcoded caps (partly)
Low: Search results re-announced on every keystroke

Left open (9):

Medium: Element entries never refresh: There is no cheap version key. Element provider records don't change, and the dependency count is only readable through ɵgetDependenciesFromInjectable, which is the costly call the cache avoids. Re-reading every element on every tick is a performance trade-off that needs a decision, and it overlaps with phase 3 of 4: a shell you live in #342.
Medium: Environment injectors off the rendered path are missing: Needs new discovery from Router internals (_injector/_loadedInjector) through a minified token lookup, plus a new 'inactive' state. That is larger than a local fix and needs a design decision.
Low: Panel types drift from the package: The package has no types export and the panel keeps local copies of types on every page. Importing the shared types needs a new public export or tsconfig path, which is a project-wide decision.
Low: Tokens matched by name only: Needs token ids across collector, report, tools and panel. Too large for this batch.
Low: Live view hides source data: A larger panel feature (joining live tokens to source providers with links). Not local.
Low: Unknown provide*() helpers are dropped: Changes what source mode lists and adds a new entry kind. Needs a product decision on false positives; the docs limits section already describes this.
Improvement: Resolution path graph: A new UI feature that needs design.
Improvement: Orphaned providers: Spans package and panel and needs design.
Improvement: Warning count badge on the Injectors dock: Needs a product decision and dock plumbing.

#346 (signals)

Fixed (8):

Medium: Write hook cost (serialize on every write inside Angular's set path)
Medium: Unnamed writes dropped silently (partly)
Low: Track eviction is FIFO, not LRU
Low: History owner ignores injectors
Low: Quadratic dependency lookups
Low: Filter matches every resource
Low (to confirm): linkedSignal writes may skip the hook
Improvement: Count unnamed signals in inspect-signals

Left open (5):

Low: Peeks only take environment injectors: This changes the peek wire protocol, the page-side matching and the inspect-signals wait. Every unmatched component selector would then wait up to 1.5s, and many existing tests rely on the current flow. It is better done as its own change.
Low: Live nodes not linked to source: Needs new label and class matching with ambiguity rules plus new card UI. Too large for this batch.
Improvement: Restore a past value from history: Blocked on signal editing (phase 2 of 4: deeper inspection #341).
Improvement: JSON diff between consecutive history entries: Needs new diff UI and design decisions; not small.
Improvement: Effect run counts and durations: Depends on an Angular hook that is not confirmed to exist. This is a design question.

#350 (pipes)

Fixed (11):

Medium: Pages mixed in the panel
Medium: impure-pipe-in-for noisy for built-ins
Medium: No transform timing
Medium: No usage sites for custom pipes
Low: Thrown transforms are not recorded
Low: Own-property and subclass transforms
Low: Stale check silently inactive
Low: Silent truncation (partly)
Low: Per-instance rows lack the component
Low: call and stale are not validated
Low: First calls of new pipe classes are missed (partly)

Left open (8):

Low: Full source scan on every request: Needs a shared mtime-keyed index invalidated from the Vite watcher. That spans several files plus the server lifecycle, so it is too big for a small fix.
Low: False duplicate async subscriptions: Choosing which sources count as 'obviously shared' (Subject, shareReplay, store.select) is a heuristic and product decision, not a local fix.
Improvement: Hot pipes sort and view: New view and sort in the panel, which needs a UI/product decision. Timing data now exists for it.
Improvement: Per-template pipe list in Components inspector: Cross-inspector feature, not local.
Improvement: Migration suggestions as agent actions: New agent action tools and config entries, which needs a design decision.
Improvement: Detect identical-result churn: Needs per-call deep-equality tracking and a threshold decision.
Improvement: Label library pipes by node_modules package: Overlaps the runtime-only library pipes tracked in phase 1 of 4: safe by default and wired into your workflow #340.
Improvement: pipe-usages agent resource: New public agent resource plus config entries, which needs a decision. The custom usage data it would serve now exists in get-pipes.

#351 (HTTP, SSR and hydration)

Fixed (5):

Medium: compression breaks SSR sniffing and state edits
Low: client cache check disagrees with the server one (partly)
Low: server 'cache hit' is misleading
Low: hydration scan goes stale (partly)
Low: duplicated, unanchored URL glob (partly)

Left open (11):

Medium: network inspector page is too big (split into child components and a store): A large refactor across the whole panel page, not a small fix; it needs its own change.
Low: console patch moves every call site: The issue says this should land with the single console tap planned in phase 3 of 4: a shell you live in #342; it also needs build/source-map changes.
Improvement: payload tab extras: New UI features plus a refetch action; needs a design decision.
Improvement: hydration mismatch diff with overlay highlight: Cross-cutting: overlay, component tree and panel; not small.
Improvement: duplicate/waterfall lint and lint-http agent tool: New agent tool and new analysis; not small or local.
Improvement: Copy as fetch/cURL and replay: New panel feature with a write action; needs a design decision.
Improvement: HAR export: New export feature; not small.
Improvement: Server-Timing entry per server HttpClient call: Changes the Server-Timing format and needs per-call tracking across http.ts and the middleware; better done on its own.
Improvement: rule presets (offline, slow 3G, flaky): New rule semantics and UI; a product decision.
Improvement: label httpResource/resource()/@defer calls: Needs a design for detecting the call origin.
Improvement: record native fetch calls: Large new collector on both sides.

Review follow-up

ssr-middleware decided whether a body was compressed after the response was sent, so a correctly ordered compression() made every render read as compressed. It now latches the encoding when headers go out, with a test for both mount orders.
A Content-Encoding passed only to writeHead is now seen too, and unedited bodies go out as their original bytes.
An opted-in POST whose cached response arrives later counts as a cache hit, matched on the body-sensitive key only.
Element injectors get their own 2000 node budget; environment injectors get what is left of 2500.
The server clamp keeps a pipe's instance total when it cuts per-instance rows.

How it was verified

pnpm commit:check
pnpm format:check
pnpm typecheck (includes the ngc template checks)
pnpm test:devtools and pnpm test:panel
pnpm skills:check (when .claude/ changed)
Docs in apps/docs updated and pnpm docs:build passes
pnpm extension:build and extension/ui committed
Checked in the browser with axe (when the UI changed)

Notes for reviewers

Items marked (to confirm) in the issues were only fixed when the code confirmed them.
Skipped items need a product decision or are larger, cross-layer changes; each one has its reason above.

Summary by CodeRabbit

New Features
- Pipe insights now include transform timing, errors, per-instance callers, and template usage locations for custom pipes.
- Injector views show change-detection mode, cap provider results with a “+N more” indicator, and announce search results after typing pauses.
- Signal details provide additional context for sampled or unnamed signals.
- SSR request details explain when prior compression prevents render-mode detection or TransferState edits.
- HTTP and SSR patterns support ^ to anchor matching at the URL path start.
- Defer-block listings identify placeholders waiting for user triggers.
Bug Fixes
- Change-detection recordings preserve active data when recording is started again, and nested cycles are handled more reliably.
- Component picking works with touch input and SVG elements; failed injector reports can be retried.

@let

… intact Picking let pointer presses reach the inspected app and did not work on touch, a second start wiped a running change detection recording, and output triggers older than 50 ms were credited to a later tick. Swallow presses while picking and handle touch, keep the running recording on a repeated start, and drop stale output triggers. Also highlight SVG and shadow-root elements, handle nested-tick cycles, stop caching null host ids, move the shared CD types into the config entry, make defer rows focusable, and keep defer blocks that only wait for viewport, interaction or hover out of Needs attention. Document the @let gap and every behaviour change in the components and tools pages. Refs #344

… pushes InjectionToken factories lost their dependencies, push-injector-tree accepted any payload without limits, the Angular-native overlay gave up after one failed push, and the NativeScript overlay connection dropped when idle. Read factory dependencies, validate pushes with valibot and cap their size, retry failed pushes, and send a keepalive ping. In the panel, label the change detection mode, add a "+N more" note after the Provided by chips, and announce one debounced search summary instead of re-reading on every keystroke. Update the injectors and resources docs pages to match. Refs #345

The write hook serialized values inside Angular's set path, which slowed every write and could throw from inside it. Serialize writes in a microtask instead, and evict write tracks least recently written first so busy signals are kept. Delta history now tells injector owners apart on both the page and the server. In the panel, precompute dependency lookups, stop short filters from matching every resource, and explain missing set entries on the cards. inspect-signals now reports an unnamedSignals count. A real Angular test pins the linkedSignal behaviour, and the signals and tools docs pages describe the changes. Refs #346

Pipe recording missed calls, dropped calls that threw, and did not wrap class-field or subclass transforms. Time every call, record throwing calls and rethrow them, and wrap both kinds of transform. Custom pipes now get template usage sites, the impure-pipe-in-for rule skips async and json, and the server validates page reports and clamps their size. The panel shows only its own tab when several tabs report, and adds timing, errors, the component and caller for each instance, truncation counts and an unavailable state for the stale check. explain-pipe and the pipes and tools docs pages are updated to match. Refs #350

When ssrMiddleware ran after compression(), it sniffed and edited encoded bodies. Skip encoded bodies, and tell the user in the request detail, the agent tool and the docs to mount ssrMiddleware after compression(). Server calls were also reported as transfer cache hits; the client and server now share one cache-eligibility predicate, which also handles fetch credentials. The hydration scanner no longer stays stale when ngDevMode is plain true, and URL globs go through one helper anchored with ^. Refs #351

Rebuild extension/ui from app so the committed bundle includes the panel changes for the components, injectors, signals, pipes and HTTP inspectors.

The compressed-body check read Content-Encoding after the response finished. With compression() mounted before ssrMiddleware, the order the docs ask for, compression sets that header during writeHead, so every compressed render lost its render mode and the request detail and agent tool told the user to fix an order that was already right. Read the encoding when the headers go out, before compression's own header hook runs, and record it as compressedBeforeTrace. The panel and the agent tool key the compression note on that field.

📝 Walkthrough

Walkthrough

This pull request updates change-detection recording, component interactions, injector reporting, pipe and signal data, and HTTP/SSR reporting. It changes data collection and matching, updates inspector displays, and adds related tests and documentation.

Changes

Change detection recording

Layer / File(s)	Summary
Recording types and cycle capture `packages/devtools/src/config.ts`, `packages/devtools/src/cd-recorder.ts`, `packages/devtools/src/__tests__/cd-recorder.test.ts`, `apps/docs/src/content/inspectors/components.md`	Recording types are shared through config. The recorder tracks nested cycles and retains output triggers only within the 50 ms window.
Recording overlay and report types `packages/devtools/src/cd-overlay.ts`, `app/src/pages/cd-recording.ts`, `apps/docs/src/content/agents/tools.md`	The overlay reuses the shared report type, retries unresolved host IDs, and preserves an active recording on a repeated start.

Component inspection interactions

Layer / File(s)	Summary
Component picking and highlighting `packages/devtools/src/component-pick.ts`, `packages/devtools/src/page-highlight.ts`, `packages/devtools/src/__tests__/component-pick.test.ts`, `packages/devtools/src/__tests__/page-highlight.test.ts`, `apps/docs/src/content/inspectors/components.md`	Picking supports release-based selection and suppresses the following click. Highlighting accepts SVG component hosts and includes shadow-root children when calculating bounds.
Defer-block state and rows `packages/devtools/src/rpc/component-tools.ts`, `app/src/pages/component-tree.ts`, `packages/devtools/src/__tests__/defer-blocks.test.ts`, `app/src/__tests__/component-tree-defer.test.ts`, `apps/docs/src/content/agents/tools.md`	Blocks waiting only for user triggers receive a distinct note. Ownerless rows expose `aria-disabled="true"` and display “Unknown component.”

Injector reporting and inspection

Layer / File(s)	Summary
Injector report validation and storage `packages/devtools/src/rpc/injector-report.ts`, `packages/devtools/src/devframe.ts`, `packages/devtools/src/__tests__/injector-report.test.ts`, `apps/docs/src/content/agents/resources.md`	Injector reports are validated, clipped, and bounded before storage. Truncation reflects the input report or sanitizer results.
Environment dependencies and injector search `packages/devtools/src/injector-tree.ts`, `app/src/pages/di-inspector.ts`, `packages/devtools/src/__tests__/injector-tree.test.ts`, `app/src/__tests__/di-inspector-pages.test.ts`, `apps/docs/src/content/inspectors/injectors.md`	Dependency lookup includes resolved factory-backed object tokens. The inspector displays zone labels, limits provider chips to 12, and announces search results after typing pauses.
Injector-tree retry and keepalive `packages/devtools/src/overlay-angular-native.ts`, `packages/devtools/src/overlay-nativescript.ts`, `packages/devtools/src/__tests__/overlay-angular-native.test.ts`, `packages/devtools/src/__tests__/overlay-nativescript-report.test.ts`	Failed pushes clear cached tree data for retry. The NativeScript overlay pings before resending an unchanged tree during keepalive.

Pipe usage and runtime reporting

Layer / File(s)	Summary
Transform instrumentation and collection `packages/devtools/src/pipes-runtime.ts`, `packages/devtools/src/pipes-collector.ts`, `packages/devtools/src/__tests__/pipes-runtime.test.ts`, `packages/devtools/src/__tests__/pipes-collector.test.ts`	Instrumentation records transform durations and thrown values while rethrowing errors. Collection reports aggregate and per-instance timing, errors, caller and target data, and async usage totals.
Pipe report contracts and aggregation `packages/devtools/src/rpc/pipes-tools.ts`, `packages/devtools/src/rpc/pipe-explain.ts`, `packages/devtools/src/__tests__/pipes-pages.test.ts`, `packages/devtools/src/rpc/__tests__/pipe-explain.test.ts`	Page reports add timing, error, stale-check, and async-total fields. Validation and clamping bound report data, and aggregation combines reports from multiple pages.
Pipe discovery and inspector display `packages/devtools/src/rpc/get-pipes.ts`, `packages/devtools/src/rpc/pipe-lint.ts`, `app/src/pages/pipes-inspector.ts`, `app/src/__tests__/pipes-record-page.test.ts`, `packages/devtools/src/rpc/__tests__/pipe.test.ts`, `apps/docs/src/content/inspectors/pipes.md`, `apps/docs/src/content/agents/tools.md`	Usage scanning includes custom pipes, while loop linting excludes `async` and `json`. The inspector displays usage locations, page-scoped data, timing, errors, and per-instance details.

Signal history and graph inspection

Layer / File(s)	Summary
Signal history capture and ownership `packages/devtools/src/signal-history.ts`, `packages/devtools/src/signal-graph.ts`, `packages/devtools/src/overlay.ts`, `packages/devtools/src/devframe.ts`, `packages/devtools/src/__tests__/signal-history.test.ts`, `packages/devtools/src/__tests__/agent-tools.test.ts`	Writes are serialized asynchronously, and track eviction uses weak-reference availability and write recency. Signal history deltas are reused only when graph owners match.
Signal graph metadata and details `packages/devtools/src/rpc/signal-tools.ts`, `app/src/pages/signal-inspector.ts`, `packages/devtools/src/__tests__/signal-tools.test.ts`, `app/src/__tests__/signal-inspector.test.ts`, `apps/docs/src/content/inspectors/signals.md`, `apps/docs/src/content/agents/tools.md`	Graph reports count unnamed signal-like nodes. The inspector uses cached dependency relations, applies a minimum prefix length for resource-kind matching, and shows hints for sampled-only histories.

HTTP and SSR reporting

Layer / File(s)	Summary
Transfer-cache eligibility and hydration scans `packages/devtools/src/http-cache-reason.ts`, `packages/devtools/src/http.ts`, `packages/devtools/src/http-hydration.ts`, `packages/devtools/src/http-overlay.ts`, `packages/devtools/src/__tests__/http.test.ts`, `packages/devtools/src/__tests__/ssr-cache-and-navigation.test.ts`, `apps/docs/src/content/guides/ssr-http.md`, `apps/docs/src/content/inspectors/ssr-http.md`	Request-side cache checks are shared, server responses are not reported as cache hits, and hydration scans without counters refresh when the five-second time bucket changes.
Shared HTTP and SSR URL matching `packages/devtools/src/url-glob.ts`, `packages/devtools/src/http-rules.ts`, `packages/devtools/src/ssr-overrides.ts`, `packages/devtools/src/rpc/http-rule-tools.ts`, `packages/devtools/src/__tests__/http.test.ts`, `app/src/pages/network-inspector.ts`, `apps/docs/src/content/agents/tools.md`, `apps/docs/src/content/inspectors/ssr-http.md`	HTTP rules and SSR overrides use shared glob matching. A leading `^` anchors matching to the start of the URL path.
Compression-aware SSR tracing `packages/devtools/src/ssr-middleware.ts`, `packages/devtools/src/ssr-registry.ts`, `packages/devtools/src/rpc/ssr-tools.ts`, `app/src/pages/network-inspector.ts`, `packages/devtools/src/__tests__/ssr-overrides.test.ts`, `apps/docs/src/content/guides/ssr-http.md`, `apps/docs/src/content/inspectors/ssr-http.md`	The middleware detects compression that precedes it, skips edits to encoded bodies, and records compression metadata. Request details display the encoding and the limits on render-mode detection and TransferState edits.

Extension bundle references

Layer / File(s)	Summary
Generated asset references `extension/ui/index.html`, `extension/ui/assets/browser-agent-rpc-BXhoSh1z-wXf_92mg.js`	The UI script and RPC bridge import reference the updated generated JavaScript asset name.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to e2365

The reported SSR encoding issue does not affect recorded HTML responses. No identified issue remains that should block merging after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to e2365

The inspected changes strengthen report validation and limit retained data without demonstrating new privileges or broader access. Confidence remains limited because enforcement of page identity at the connection boundary was not established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The directly inspected exposure is report integrity and resource consumption within a devtools host serving connected pages. Accepted reports enter shared inspector state, and injector reports are also exposed through the injector-tree resource. Wider tenant, production, or infrastructure exposure was not established.

Trust Boundaries and Controls

observed — The ingestion boundary now drops malformed injector records and limits accepted tree depth, node counts, provider lists, dependencies, and text. Pipe ingestion validates nested call fields and clamps selected retained lists and text. These controls improve containment but do not establish caller authentication.

Resilience and Maintainability Implications

inferred — Per-page snapshot replacement avoids accumulating repeated reports for the same key. The inspected validation and cleanup transitions did not demonstrate a PR-induced failure-containment regression. This is not a guarantee of transactional recovery from every publication failure or of authenticated page ownership.

Hardening Proposals

proposed — If the connection layer does not already enforce ownership, bind report pageIds to authenticated connection identity and reject cross-owner writes and deletes. This addresses an existing uncertainty, not a demonstrated vulnerability introduced by this PR.

…tact - Count a POST that opts into the transfer cache as a hit when its response arrives after subscribe. It matches on Angular's body-sensitive cache key only, never on an Analog URL entry. - Read Content-Encoding from the headers passed to writeHead as well, so a gzip body sent that way is recognised as encoded, and send unedited bodies as the original bytes instead of a UTF-8 round trip. - Give element injectors their own 2000 node budget and environment injectors what is left of 2500, so many environment injectors no longer push element injectors out of the reported tree. - Keep the instance total when the server cuts a pipe's per-instance rows, so counts cover every instance and not only the kept rows.

…know the option (#384) Angular 20.0 has no HttpRequest credentials option and drops it, so the request became a plain GET that used up the test's only transfer cache entry. The Angular compatibility run on main has failed on Angular 20.0 since #361.
