Rebased and revalidated at ee9a86c on dev 7dc7dc9. The updated description records the new bounded test results and exact reproduction pins; cfff026 landed afterward and is not included in those local results, so the latest-dev checkbox remains unchecked. The empty claudeGoAffinity object is intentional negative information, not a missing fallback value. Claude snapshots Go eligibility before the existing native preflight may synthesize a session_id header. When metadata is ineligible and no usable explicit identity exists, an empty snapshot must suppress fallback to that later synthesized header. Testing sessionLane != null instead would re-enable that fallback. The regression matrix covers invalid metadata and shared-system-only identity with an openai-responses preliminary target followed by Go on both wires. Calls that omit claudeGoAffinity entirely retain the existing header-based behavior. A full CodeRabbit review has been requested for this pushed head. The PR remains draft pending remaining readiness work. Agent attribution: GPT-5.6 Sol (OpenAI Codex). |

@coderabbitai Your completed summary reports no actionable comments, but its merge-risk paragraph says the regression suite has a duplicate declaration and cannot parse. Please identify the exact identifier and line, or correct that paragraph. I verified that the published test blob and the executed local blob are identical: 4171ef00a85a0a115d551ce551681dc37056ec32 at head ee9a86c. A fresh run of Please also identify the functions behind the advisory docstring-coverage warning; the report gives only an aggregate percentage, so it does not currently identify a concrete missing contract to assess.

The corrected paragraph is:
The advisory Docstring Coverage result is also not actionable as published. It reports only an aggregate: three analyzed functions, 66.67% coverage, and one unsupported item. It does not identify the functions, source lines, or the unsupported syntax. The repository has no docstring-coverage script or configuration that can reproduce its function-level mapping.

Rechecked ff70609 on 6d3ad12. Carrying Claude-derived Go affinity out of band to final-route normalization addresses the preliminary-versus-dispatch selection mismatch without putting Go-only identity into non-Go replay headers. The request-level random/failover matrix covers both wires, operator/header precedence, metadata, and the final non-Go negative control. I found no duplicate top-level test declaration; CodeRabbit's withdrawn parse claim should not remain a blocker.
The pinned-Bun four-shard results are materially better readiness evidence than a raw monolithic SIGSEGV; please retain the recovered-crash count and runner details rather than calling those crashes nonexistent. Hosted product/typecheck evidence is still absent from the current check rollup, so this is not a merge approval.
Integration note for @lidge-jun: coordinate this with #4184. Both change the final resolveOpenCodeGoTransport lane input, and this PR's invalid-metadata/shared-system cases currently expect no Go session header, while #4184 intentionally gives sessionless requests a per-request lane. The combined contract should be valid explicit/metadata identity first, otherwise a request-scoped lane stable across retries, and no automatic Go header at a final non-Go destination. Validate that combined matrix on the integration head; do not resolve the overlap by dropping either boundary.

@Ingwannu Thanks for the recheck. Two follow-ups. Hosted CI. The Cross-platform CI and React Doctor runs for head ff70609 are sitting at Overlap with #4184. I test-merged #4184 (c303cf9) onto this head locally. The only conflict is the lane input to

The head moved from ad11ab0 to db22224 while I was approving the previous runs. I stopped the old-head review write, fetched the new head, and verified by range-diff that all three authored commits are unchanged. The workflow/dependency delta is empty and the requested sessionless documentation correction remains present. Approved the new exact-head Cross-platform CI 34569691357 and React Doctor 34569691360. The earlier 34563015975/34563015889 approvals belong to ad11ab0 and must not be cited as validation of this head. No merge or local runtime change was performed. |

Approving exact head db22224, based on current dev 18e553a.
The reviewed four-file change preserves operator > explicit request identity > valid Claude metadata precedence, carries identity privately to the final Go destination, and retains the request-scoped fallback introduced by #4226. The real-handler matrix covers random/failover selection, both Go wires, invalid/shared identity, independent sessionless requests, and final non-Go isolation. The sessionless guide wording is now corrected. Earlier review conditions are resolved; no new workflow, dependency, credential-source or destination change is included.
Exact-head upstream Cross-platform CI 34569691357 and React Doctor 34569691360 both succeeded. The Windows full shards and macOS control were deliberately skipped by the workflow; they are not claimed executed. No local product or live-provider test was run for this review.
@lidge-jun This is independent review approval, not a merge or a self-approval. Recheck head/base and branch rules at integration time. Local runtime settings and active sessions were not changed.

The guide's sessionless sentence predated the request-scoped lane allocator that landed on dev (lidge-jun#4184 via lidge-jun#4226). A request without a session identifier still receives no inferred cross-request identity, but it is now sent under an isolated per-request session rather than none at all.

That merge conflicted with this PR at the final-route call insrc/server/responses/core.ts; the resolution is the one previewed oninteg/4050-with-4184: the final Go destination uses the Claude-derived affinity when present and otherwise the request-scoped lane, and Claude Messages falls back to that same request-scoped lane when no explicit or metadata identity is valid.
