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.

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 I found no duplicate top-level test declaration; CodeRabbit's withdrawn parse claim should not remain a blocker.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.

Reviewed d7f40ed, including the complete four-file authored diff and the #4226 integration. The actual final Go route now prefers the carried valid Claude identity and falls back to the original request-scoped lane; the updated matrix checks distinct sessionless requests and keeps the non-Go negative control. This addresses the integration condition from my previous review.
I approved exact-head upstream Cross-platform CI 34542979054 and React Doctor 34542990514 for execution. The PR changes no workflow/dependency files, and the inspected pull_request path uses GitHub-hosted runners with read-only permissions. This is permission to execute those checks, not merge approval or an assertion that they passed.
Please also keep the guide's nearby sessionless sentence precise: no stable cross-request conversation identity is inferred, but the now-landed allocator does provide isolated per-request affinity. Current dev has advanced beyond the rebased base, so final integration still needs current-base verification.
Carry validated Claude affinity privately through combo replay and consume it only at the final canonical Go transport. Preserve explicit identity and operator precedence without leaking Go-only headers to other destinations. Addresses the late review on lidge-jun#3961. Adds deterministic random and failover regressions across both Go wires. Co-authored-by: GPT-6 Astra <noreply@openai.com>

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.

The approved upstream Cross-platform CI 34542979054 has now completed successfully at d7f40ed; React Doctor 34542990514 also passed. This is current-head hosted evidence, no longer an execution-approval hold. Full Windows shards and macOS control were skipped by the workflow, not executed. The source-level #4226 integration feedback is addressed as recorded in my review. Current dev has advanced beyond this head's base, so keep the final current-base/readiness check and the precise sessionless documentation distinction before integration.

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.
