Estimated code review effort: 4 (Complex) | ~60 minutes Severity of issue fixed: Medium Merge Risk: ⚪ Minimal · up to The V3 retrieval selector is propagated through the contract, server, providers, and SDKs with focused validation for authorization, thread fencing, routing, and response versioning.

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.

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.
