fix(responses): disable Spark Lite in WebSocket metadata - #4130
Conversation
📝 WalkthroughWalkthroughThe canonical Responses adapter now forces Responses Lite off for final Spark wire models in HTTP and native WebSocket metadata. Tests cover aliases, malformed metadata, body integrity, socket retirement, and replacement socket reuse. Architecture documentation describes the behavior in eight languages.

Suggested reviewers: Merge Risk: 🔵 Low · up to Spark requests now explicitly disable Responses Lite while preserving existing behavior for other routes. A minor French documentation style inconsistency remains, with no production behavior impact. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

리뷰 · 우선순위 71 / 80설명 이 PR은 #3885 / #3942에서 일부러 남겨 둔 WebSocket Lite 잔여를 닫는다. 지금 체크아웃 이번 tip(luvs01, Draft, base 런타임 diff는 점수 71은 “#3942가 명시한 WS residual을 올바른 한 줄로 닫고 테스트·문서까지 맞춘 CLEAR follow-up”이라서 높다. 깎은 이유는 (1) 아직 Draft, (2) 이 저장소 exact-head 제품 CI가 안 보이며, (3) live EOF를 주장하지 않아 운영 체감 확정은 머지 후 관찰이 필요하다는 점이다. 라인 2520-2523 근처 - 메인테이너의 판단이 필요한 지점

This review is limited to static request framing and socket lifecycle inspection. I did not run tests in this environment. The queued exact-head CI remains the required runtime validation. This change does not demonstrate a live ✅ Action performedReview finished.

Reviewed head 688edfe against a7509fe, including the adapter, WS preparation, and socket-reuse regression. The changed adapter and WS request/pool sources are unchanged in the base delta to current dev c15a98c.
The explicit false is necessary: deleting the HTTP header leaves a pre-existing true value in native client_metadata, while applyLiteMetadata only overrides it for explicit true/false. The final wire model and canonical destination gates preserve reverse aliases and noncanonical routes. The reuse test holds model/account/thread constant, so socket retirement cannot pass merely because the model changed. Malformed metadata still preserves the original HTTP body.
I independently verified author CI run 34412471553 completed successfully at this exact head. I am sponsoring the PR for the remaining repository gates, not waiving them or merging it. This supports the wire-metadata/lifecycle correction, not a claim that every live Spark EOF is resolved. No live account traffic or local product execution was used.

Summary
The canonical Spark adapter currently removes the Responses Lite header, but a native WS request can still carry
client_metadata.ws_request_header_x_openai_internal_codex_responses_lite: "true". WS preparation preserves that value when the header is absent. Set the final Spark request's Lite header explicitly to"false"so the existing WS preparation also overrides the stale frame metadata.This is the separate WS follow-up explicitly left out of #3942 and discussed in the original maintainer scope decision. The earlier HTTP fix was intentional and is already integrated. This PR verifies request framing and socket lifecycle; it does not claim a live post-release Spark
adapter_eofreproduction or a verified backend EOF fix.The override applies only to canonical ChatGPT forwarding whose final outgoing model is
gpt-5.3-codex-spark, including aliases. Caller and configured header spellings are replaced consistently. Other models/gateways retain their existing policy, and malformed native metadata remains eligible for HTTP fallback with its body unchanged. The existing pool retires a socket when its Lite identity changes and can reuse the new disabled identity for subsequent eligible requests. Runtime scope is one header assignment; architecture documentation is synchronized in eight locales.Verification
