Room memory retrieval needs to search multiple threads inside one authorized space and memory scope. V2 treats a null thread as unthreaded-only, so callers cannot express that query without changing existing semantics.

Add opt-in context-retrieval.v3 with explicit exact/any thread selectors and separate capability negotiation. SQL, Qdrant and canonical hydration preserve exact admitted source/generation filtering; neighbors stay anchored to the seed thread. V2 contracts and null behavior remain unchanged. Python and TypeScript SDKs expose the new capability and retrieval methods. Scoped service tokens use the handler's bounded decoding and pre/post-resolution authorization.

Validation: focused Python suites passed, including 69 auth/route tests. SDK 352 tests covered across the main run and an isolated Git fixture retest; build, exports and consumer installation passed. Independent review of exact 311580d found no actionable P1/P2 after closing the scoped-token defect, independently running 102 Python tests with 15 subtests and 49 SDK tests. Lint and diff checks passed. Full CI is requested here.

This is retrieval infrastructure evidence, not measured memory-answer quality. Live qualification follows a newly versioned SDK draft artifact; the existing immutable 0.2.4 release is not replaced.

Summary by CodeRabbit

  • New Features
    • Added the context-retrieval.v3 contract with explicit exact and any thread selectors.
    • Added dedicated retrieval and capability endpoints with capability validation and negotiation.
    • Added V3 retrieval support to the Python and TypeScript SDKs.
    • “Any” selection retrieves across threaded and unthreaded partitions while preserving authorization and data-scope safeguards.
  • Compatibility
    • Existing V2 retrieval behavior and null-thread semantics remain unchanged.
  • Documentation
    • Documented the V3 retrieval architecture and acceptance criteria.
  • Tests
    • Added coverage for selectors, authorization, capability validation, transport errors, and cross-version rejection.

📝 Walkthrough

Walkthrough

The change adds a V3 context retrieval contract with explicit exact and any thread selectors. It adds server routes, capability negotiation, core and provider filtering, Python and TypeScript SDK support, and validation coverage while preserving V2 behavior.

Changes

Context retrieval V3

Layer / File(s) Summary
V3 contract and selector validation
docs/adr/..., packages/infinity_context_contracts/..., tests/contracts/..., tests/architecture/...
Defines V3 request, response, capability, and thread-selector validation. V2 wire behavior remains strict.
Core and provider filtering
packages/infinity_context_core/..., packages/infinity_context_adapters/..., tests/unit/..., tests/adapters/...
Carries thread_mode through core retrieval. Exact mode keeps thread filtering. Any mode removes only the thread predicate while retaining canonical fences.
Server routing and execution
packages/infinity_context_server/..., tests/server/...
Adds V3 POST and capability endpoints, maps V3 requests, validates capability fingerprints, and executes profile queries with existing lifecycle controls.
SDK exchange
packages/infinity_context_sdk/..., packages/infinity_context_ts_sdk/..., packages/infinity_context_ts_sdk/tests/..., tests/unit/test_sdk_retrieval.py
Adds V3 capability retrieval and context retrieval to both SDKs. Requests select the V3 endpoint and reject V2 capabilities or downgraded responses.
Architecture and routing parity checks
tests/architecture/..., packages/infinity_context_ts_sdk/scripts/..., packages/infinity_context_ts_sdk/tests/...
Records feature ownership and route ownership. The parity checks validate V2 and V3 routing and transport patterns.

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

Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to 950c1

The V3 retrieval selector is propagated through the contract, server, providers, and SDKs with focused validation for authorization, thread fencing, routing, and response versioning. No merge-blocking risk remains.

In
`@packages/infinity_context_server/infinity_context_server/api/v1/context_retrieval.py`:
- Line 73: Update retrieval_v3_descriptor around locator_retrieval.descriptor()
to enforce MAX_DEADLINE_SECONDS with asyncio.timeout and catch
descriptor-related RuntimeError or timeout failures, returning the route’s
canonical unavailable response. Preserve the existing successful descriptor
response behavior.

In `@packages/infinity_context_ts_sdk/scripts/check-retrieval-parity.mjs`:
- Line 33: Update the enforced retrieval parity checks in the TypeScript and
Python validation paths to assert V2 and V3 retrieval route selection
separately, rather than allowing the V3 branch to be optional. Ensure each SDK’s
check independently verifies the V2 default route and the explicit V3 route,
while preserving the existing stream-call assertion.

In `@tests/server/test_locator_retrieval_route.py`:
- Line 290: Update the malformed-selector test around the retrieve-v3 request to
require a 4xx status, not any status at or above 400, so server errors remain
failures; where the response exposes the established error payload, also assert
its canonical retrieval error code.
