Summary

Closes #6162.

  • Canonical ChatGPT non-streaming requests use SSE upstream and return one bounded, validated Responses JSON object. Streaming requests retain SSE, and other providers keep their existing wire behavior.
  • Reject malformed, truncated, stalled, oversized, or contradictory terminals before publishing continuation and serving-route state. A disconnect during deferred replay returns 499 before the serving-route commit.
  • Redact the selected outbound credential from failed/incomplete terminal events and synthetic error responses, including buffered JSON built from bare upstream SSE errors. Both tee and eager synthetic failure tails redact exception messages before serialization.
  • Preserve the existing bounded collector, request-log accounting, and recovery behavior described in structure/decisions/ADR-6162-responses-http-sse.md.

Verification

  • bun install --frozen-lockfile passed.
  • bun test tests/responses/responses-canonical-nonstream.test.ts tests/responses/responses-pool-401-refresh.test.ts tests/responses/sse-failed-tail.test.ts tests/responses/passthrough-abort.test.ts: 149 passed, 0 failed at merged commit 646ebf471f. The final refusal-field follow-up changed only relay.ts and its focused test; canonical non-stream and synthetic-tail tests then passed 93/93 at 3ffe4dd10a.
  • bun test tests/usage/request-log-nonstream.test.ts: 9 passed, 0 failed. bun test tests/server/server-auth.test.ts in isolation: 117 passed, 0 failed.
  • bun test tests/ci-workflows/file-size-ratchet.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts: 27 passed, 0 failed.
  • At f072b94a26, bun test tests/responses/responses-canonical-nonstream.test.ts tests/responses/responses-pool-401-refresh.test.ts tests/responses/sse-failed-tail.test.ts tests/responses/responses-core-modules.test.ts passed 135/135. The Pool bare-error regression failed before the fix with the raw selected token in HTTP 502 JSON, then passed after the fix. The prior exact-head CI failure in test 1/4 was the missing terminal-error-redaction.ts core-owner inventory entry; the isolated assertion failed before the roster fix and passed after it.
  • At f072b94a26, bun install --frozen-lockfile, bun run typecheck, bun run privacy:scan, git diff --check, 18 test-layout tests, and the file-size repository assertion passed. bun run structure:check passed on the branch and on a clean synthetic merge with origin/dev (99878c3569).
  • The earlier pool-issuer regression was driven red by temporarily restoring the premature commit (499 with issuer work), then green after moving the commit past the final abort check. The terminal and synthetic-failure tests also failed before their fixes.
  • bun run test:changed selected 581 files and was stopped before completion due to contention across four RT6 worktrees; no result is claimed for it. The full suite is left to exact-head CI for the same reason. Required exact-head CI for f072b94a26 and independent security review remain pending.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. Independent review of the new head is pending.

Design record

structure/decisions/ADR-6162-responses-http-sse.md records the client/upstream wire split, terminal authority, and bounded JSON tradeoffs.

📝 Walkthrough

Walkthrough

Canonical Codex Responses requests now use upstream SSE, including when clients request JSON. The server bounds, validates, and reconstructs the terminal response before returning JSON. Streaming clients retain SSE delivery, and explicit store values remain unchanged.

Changes

Canonical Codex non-streaming Responses

Layer / File(s) Summary
Upstream streaming and retry contract
src/adapters/openai-responses/passthrough.ts, src/server/responses/adapter-delivery.ts, src/server/responses/passthrough-dispatch.ts, src/server/responses/core-codex-account.ts, tests/responses/*, tests/server/server-auth.test.ts
Canonical requests use upstream SSE across initial sends, recovery, OAuth replay, and pool-account retries. Buffered canonical requests remain on HTTP transport.
Bounded terminal collection and reconstruction
src/server/relay.ts, src/server/responses/buffered-sse-json.ts, tests/responses/responses-canonical-nonstream.test.ts
The implementation validates framing, UTF-8, terminal status, output indices, reconstructed output, byte limits, frame limits, and timeout deadlines. It classifies malformed, incomplete, cancelled, oversized, and read-failure results.
Validated JSON delivery and finalization
src/server/responses/passthrough-delivery.ts, src/server/responses/terminal-error-redaction.ts, src/server/responses/core-lifetime.ts, src/server/responses/passthrough-error.ts, tests/usage/request-log-nonstream.test.ts
Raw and rewritten SSE must validate before serving-state commits and deferred effects. Terminal diagnostics are redacted. Client cancellation returns 499. Preinspected JSON markers survive response finalization.
Protocol, tests, and timeout documentation
structure/decisions/ADR-6162-responses-http-sse.md, structure/transports/*, structure/providers-and-adapters.md, docs-site/src/content/docs/*, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
The ADR and documentation describe SSE-to-JSON conversion, reconstruction rules, limits, timeout behavior, error outcomes, and unchanged streaming behavior. Tests cover request construction, reconstruction, retries, cancellation, limits, and error mapping.

Merge Risk: 🟡 Moderate · up to 9da57

Non-streaming canonical Responses can return or commit a response without a validated terminal event, and bare upstream errors may expose credentials. Resolve these before merging. The abort test's real-timer use is a minor flakiness concern.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 9da57

The new buffering flow improves validation and cancellation handling, but a successful upstream response labeled as JSON can still avoid its terminal checks. Error redaction also differs between ordinary terminal events and bare upstream errors. The practical exposure of the latter needs further confirmation.

Retained concerns

  • Medium · security · observed: A successful canonical upstream application/json response takes the older JSON delivery path instead of the new SSE terminal-validation path. Its serving route can be committed without the terminal proof required for buffered canonical responses.
  • Low · security · observed: The header-value-aware redaction control does not cover bare upstream error events or the buffered path’s synthetic JSON failure. Those paths rely on a separate, pattern-based redactor, leaving protection of an unlabelled echoed credential unestablished.
Security review details

Security Blast Radius

  • inferred — The relevant exposure is the client-facing Responses delivery path for canonical OpenAI-forward providers. The evidence does not establish a change to authentication privileges, other providers, or deployment topology.

Security Findings and Attack Paths

  • observed — An upstream bare error is excluded from the header-value-aware terminal rewrite. Its diagnostic can instead reach the buffered synthetic-error formatter; generic redaction limits some credential formats, but does not establish masking of every opaque outbound credential value.

Trust Boundaries and Controls

  • observed — For recognized SSE terminals, the proxy validates upstream bytes before applying client rewrites and validates the result again before publishing deferred state or JSON. Application/json responses remain outside that new control.

Resilience and Maintainability Implications

  • observed — Byte, frame, reconstruction, and deadline checks bound the new SSE path; abort and rewritten-validation failures return before its normal completion-state write.

Hardening Proposals

  • proposed — Make a successful canonical upstream response pass the same terminal-validation gate regardless of its declared content type, and apply outbound-header-value-aware masking to bare errors and synthesized client failures.

The implementation had two independent final audits for correctness and resource bounds; their sparse-terminal, upstream-wire recovery, aggregate-frame, duplicate-copy and request-log reparse blockers were incorporated before this head. No security scan was run.

the terminal stream into the client-requested JSON shape, and returns an error
rather than partial JSON if validation fails. Preserve each page’s language and
ensure none contradicts or omits this behavior.

Review comments at @src/server/responses/passthrough-delivery.ts:
- Around line 806-813: Update collectBufferedResponsesSse and
BufferedResponsesSseFailure to retain the boundary’s upstreamError and
upstreamRefusalCode before disposal. In the missing-terminal failure path that
calls failBufferedTurn, pass any captured error and refusal code through the
existing formatter, and record logCtx.terminalHttpStatus ?? 502 with
terminalRecorder; preserve the current generic fallback when neither field is
present. Add a regression case for an error-only response carrying a refusal
code.
- Around line 795-799: Update the buffered canonical-turn call to
collectBufferedResponsesSse so its read options set first-byte and inactivity
deadlines from resolveStallTimeoutMs; when the stall budget is disabled, use a
documented nonzero fallback rather than passing zero. Define a separate generous
or configurable total-turn ceiling, and document the selected deadlines and
MAX_BUFFERED_RESPONSES_SSE_FRAMES alongside the buffered-response limits in the
proxy-formats reference.

Hosted test 1/4 exposed one non-passthrough branch missed by the initial change: routed compaction kept a JSON client contract but its canonical upstream was now SSE, while adapter delivery still called parseResponse on that SSE body. Fixed at 6fe84bf by separating actual upstream wire mode from client delivery there too and folding canonical SSE through parseStream before compaction synthesis.

Capped regressions: the full compaction-override suite plus canonical nonstream suite pass 84/84; structure check passes. The 1.5 GiB local typecheck cap remains enforced, so exact-head hosted CI is the final typecheck/build evidence. @lidge-jun please review the new head after CI. @coderabbitai review

리뷰 · 우선순위 62 / 80

이 PR은 이슈 #6162를 고칩니다. 힌드사이트처럼 OpenAI 호환 프로그램이 stream을 끄거나 빼면, 코덱스 계정 요청은 Stream must be set to true라는 400으로 끝났습니다. 같은 내용을 stream: true로 보내면 됐습니다.

고친 방식은 이렇습니다. 손님이 원한 stream 값은 그대로 기억합니다. 코덱스 공식 주소로 나가는 마지막 요청만 stream: true로 바꿉니다. store는 그대로입니다. 그 주소는 글을 한 줄씩 보내는 SSE만 받습니다. 오픈코덱스는 그 줄을 모아서 검사하고, 검사가 끝난 뒤에만 JSON 한 덩어리로 손님에게 돌려줍니다. 줄이 깨지거나, 잘리거나, 너무 크거나, 끝이 없으면 JSON을 주지 않고 실패로 닫습니다. stream: true를 원한 손님과, 공식 주소가 아닌 프로바이더는 예전과 같습니다.

한도는 프레임 4 MiB, 원문과 출력 각 32 MiB, 출력 항목 1만 개, SSE 프레임 10만 개입니다. 손님이 중간에 끊으면 499이고, 그때는 완료 상태를 올리지 않습니다.

src/server/responses/buffered-sse-json.ts - 이 모으기는 JSON 본문용 시계를 그대로 씁니다. 글이 30초(UPSTREAM_JSON_BODY_INACTIVITY_TIMEOUT_MS) 동안 없으면 멈추고, 전체는 180초(UPSTREAM_JSON_BODY_TOTAL_TIMEOUT_MS)입니다. 스트리밍 릴레이(src/server/relay.ts)에는 이 30초 침묵 제한이 없습니다. 모델이 생각하는 동안 30초 넘게 조용하면, 스트리밍은 계속 가고 비스트리밍만 upstream SSE response stalled before completing이라는 502로 끊깁니다. 설정값 stallTimeoutSec(기본 300초, 0이면 끔)는 이 갈래에 들어오지 않습니다.

src/server/responses/passthrough-delivery.ts의 failBufferedTurn - 업스트림이 response.failed 대신 error 이벤트만 보내고 끝나면, terminalStatusFromParsed(src/server/relay.ts)는 그 이벤트를 끝으로 세지 않습니다. 경계 객체는 upstreamError()와 upstreamRefusalCode()에 문장과 거절 코드를 담아 두는데, collectBufferedResponsesSse는 그 값을 읽지 않습니다. 손님은 원래 이유 없이 upstream SSE response ended without one valid terminal response라는 502를 받습니다. 스트리밍은 같은 상황에서 그 문장과 거절 코드로 실패 꼬리를 만들어 줍니다. 한도 초과나 거절이, 다시 시도해도 되는 서버 오류처럼 보입니다. response.failed에 응답 객체가 제대로 있으면 이 문제는 아니고, JSON으로 돌아갑니다.

docs-site/src/content/docs/reference/proxy-formats.md - 영어 설명만 바뀌었습니다. 일본어, 한국어, 러시아어, 중국어 페이지는 예전 문장입니다.

메인테이너의 판단이 필요한 지점

이 PR은 드래프트입니다. 본문에 리베이스 뒤 전체 타입체크가 1.5 GiB에서 죽었다고 적혀 있습니다. 커밋 60339ba193의 CI가 끝나기 전에는 ready로 보면 안 됩니다.

30초와 180초를 JSON 본문 시계 그대로 둘지, 스트리밍과 같이 stallTimeoutSec를 쓸지 정해 주세요. 이 수집기에서 0은 바로 만료가 아니라, 시계를 끈다는 뜻이어야 합니다.

error만 있는 스트림을 지금처럼 일반 502로 둘지, 스트리밍처럼 원래 메시지와 거절 코드를 손님에게 보여줄지 정해 주세요.

너의 추천

지금은 머지하지 마세요. 침묵 제한과 error 이벤트 처리를 스트리밍과 맞춘 다음 테스트를 두 개 더 넣으세요. 하나는 30초보다 긴 공백 뒤에 정상 response.completed가 오는 경우입니다. 다른 하나는 error 이벤트에 거절 코드가 있을 때 그 코드가 일반 502 문구로 사라지지 않는 경우입니다. 번역 문서는 영어와 같은 계약으로 고치세요. CI가 이 헤드에서 통과한 뒤에 ready로 올리세요.

Addressed all current review findings and rebased cleanly onto current dev (528ca33284, including #6189). Exact head: 39c5face9d592d6329f59c8d239643f92c8b6823.

  • canonical buffered turns now use configured stallTimeoutSec for first-byte/inter-chunk silence and one shared absolute 15-minute whole-turn ceiling; disabled stall budgets cannot expire immediately
  • bare error events retain bounded structured type/code: fatal refusals preserve non-retryable codes without inherited or inferred Retry-After; recognized rate/auth/quota/context/overload families keep aligned HTTP/body/outcome status; unknown/reset codes remain generic 502 regardless misleading copy
  • ja/ko/ru/zh-CN plus the remaining locale proxy/config references now document the same contract and resource limits
  • independent source rereview found no remaining P0–P2 after the final corrections

Post-rebase capped validation: 98/98 focused tests, structure SSOT, file-size ratchet, and diff check pass. A full local typecheck was attempted under the enforced 1.5 GiB RAM / 75% CPU cap and was OOM-killed rather than raising the limit; exact-head hosted CI is the typecheck/build authority.

Rebased onto current dev 8d53c2138314a73c58b58adf8ea74fe3920d5082 and fixed the exact-head Bun 1.4.0 CI failure. New exact head: d0cae55e5ccd395066e131a87e3ce810fd14e4b1.\n\nThe three native-main read-fence failures were deterministic test isolation/fixture defects exposed by the new canonical upstream-stream contract: an unowned auth control launched a detached quota prime into the next case, main-account module state was not reset, the stored token was not a time-valid JWT, and canonical fetch stubs still returned JSON. The test now injects a no-op prime seam for that auth-only control, resets main identity/cache state per case, uses a valid bounded JWT, and returns canonical SSE while measuring only the inference /responses request.\n\nCapped Bun 1.4.0 validation after rebase: the previously failing exact 12-file batch is 151/151; isolated read-fence file is 9/9; structure SSOT, file-size ratchet, and diff check pass. Current dev control was also 151/151, confirming the old PR head regression. @lidge-jun please review after the new exact-head CI. @coderabbitai review

Pushed exact head 17e8433 after reproducing the hosted test-4/4 307→502 failure locally.\n\nRoot cause: canonical non-stream requests are intentionally rewritten to upstream stream:true, which also let the transport selector choose WebSocket. That bypassed manual HTTP redirects. The fix keeps JSON-client canonical sends on HTTP/SSE across the initial send, transient/401/429 replays, and alternate Codex Pool account recovery.

@Ingwannu, PR #6200 is open as a draft at the exact head 17e8433afa74f5532e4f45b45f5cab936bd54447.

The check runs shown were queued when checked. They do not establish exact-head typecheck or build success. The CodeRabbit status says “Review skipped: draft pull request,” so the requested re-review did not produce a review. Once CI finishes, check the results for this head before marking the PR ready.

Exact head 17e8433 is now fully green, including all four test shards, gates/typecheck, structure, package checks, desktop shell, and aggregate ci. The independent full-diff re-review is GO with no remaining P0-P2, and the PR is now ready for review. @lidge-jun please take the final maintainer pass; @coderabbitai please review the ready head.

@Ingwannu, I verified that PR #6200 is open and no longer a draft. Its head is 17e8433afa74f5532e4f45b45f5cab936bd54447.

The aggregate ci check and all four test shards passed on that head. The gates, structure gate, desktop shell, and listed package checks also passed. Some optional jobs were skipped. The CodeRabbit status is successful, but that status alone does not establish that a code review found no issues.

I’ll trigger the review of the ready head. I have no code findings to report from this status check.

One new P2 reproduced on exact head 17e8433. The existing deadline/refusal/translation findings are not repeated. Validation used an isolated copy of this head with the repository test-home preload and a mocked upstream; no live provider requests were sent.

// aggregate frame cap was already enforced by both validation passes.
for (let offset = 0; offset < rawBytes.byteLength; offset += 64 * 1024) {
effectInspector.feed(rawBytes.subarray(offset, Math.min(rawBytes.byteLength, offset + 64 * 1024)));
if (offset > 0 && offset % (1024 * 1024) === 0) await new Promise<void>(resolve => setTimeout(resolve, 0));

[P2] Recheck cancellation after yielding during deferred effects

Both collectors check the client signal, but this later replay yields between MiB groups without checking it again. A client disconnect in that yield still reaches reportNativeTerminal("completed"), continuation publication, and the HTTP 200 return; the earlier 499 branches are no longer reachable. I reproduced this with 14,000 small response.output_text.delta frames followed by a valid item/terminal, scheduling abort from onFirstOutput: the result was {aborted:true,status:200,terminals:["completed"],nativeCancels:0}. Please check the signal after each yield/before further effects and final publication, use the existing cancellation cleanup/499 path, and add this post-validation cancellation regression. The existing silent-body cancellation test does not exercise this interval.

Fixed in ac5af93. The deferred inspection now checks cancellation after each yield and before terminal/cache publication, returning the existing 499 cancellation response. The new regression fails on the prior source (200 instead of 499) and passes with the fix; focused tests, typecheck, structure check, and privacy scan passed.

🟠 Major · Reject successful canonical responses that bypass SSE validation. · passthrough-delivery.ts:434-435

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Reject successful canonical responses that bypass SSE validation.

When canonicalBufferedJson is true and the upstream returns HTTP 200 with Content-Type: application/json, isEventStream is false. The response skips terminal SSE validation and reaches the JSON delivery branch, which returns the body and commits the serving route.

A successful HTTP 200 response with no body reaches the unclassified relay branch and has the same gap. Reject both cases for canonicalBufferedJson. Add regression coverage for a JSON body and an empty body. The canonical buffered path must fail when no terminal SSE event exists.

Update the canonical buffered response handling identified by
`canonicalBufferedJson` so successful HTTP 200 responses without a validated
terminal SSE event are rejected, including JSON-content responses and empty
bodies. Ensure neither case reaches JSON delivery or the unclassified relay
branch as a successful response, and add regression coverage for both.
