fix(responses): bound steering confirmation waits and preserve sparse replay output

[luvs01]

Summary

Follow-up to and dependent on #4861, following #4858 and #4782. This child implements two steering stability fixes: non-extendable confirmation/continuation deadlines and lossless reconciliation of sparse terminal output for local steering replay. Parent PR branches and readiness states are unchanged.

Stability-only comparison: luvs01/opencodex@73eb1f4...80cc768

Fixed steering deadlines

• Give every unacknowledged steering submission its own absolute 90-second deadline, measured with the monotonic clock. Stream output, later submissions and unrelated acknowledgements cannot extend the oldest outstanding deadline.
• Separate acknowledgement, automatic-successor, saved-result/approval and ordinary inactivity waits. An ended parent receives a fixed 90-second successor deadline; the first valid required-input pending event starts one 30-minute tool/approval wait; dispatching a continuation starts a fixed 90-second response-start deadline. Repeated pending events and rejection of an already queued steer do not move or cancel the submitted continuation's deadline.
• Preserve the existing sliding inactivity check while a response is actively generating. An accepted steer can still wait for the active response's safe boundary; this does not impose a blanket 90-second generation limit.
• Check deadlines synchronously before accepting a late frame or new control, so an event-loop delay cannot let an overdue event rescue an expired operation. Detach/finish clears timers; expiration disposes replay and reports unknown delivery once. No tool rerun, automatic resend, account change or HTTP fallback is introduced.

Complete local steering replay

• Reuse the result-continuation output reconciler from feat(responses): extend native result continuations and preserve hosted output #4861 in NativeSteeringReplay, instead of letting any nonempty terminal output discard completed wire items that it omits.
• Preserve missing reasoning/tool/hosted records and their ordering. Repeated identical terminal items are reconciled by identity/content; contradictory content, duplicate identities or shared-item ordering fails closed before a completed snapshot is remembered. The server's original wire terminal is not rewritten.
• Keep failed/incomplete parents private until a validated successor commits their history, and include only accepted steering in that successor. The existing 32 MiB replay budget is checked against reconciled output; overflow is not silently truncated.
• Extract the existing generic record/fingerprint implementation into dependency-free native-response-json.ts, retaining the injection module's public aliases. This avoids a replay/output/protocol/steering import cycle and preserves the source-oracle acyclic contract rather than weakening its test.
• Add 28 deterministic regressions, source-oracle/test-layout registrations and owner/public documentation. Existing defaults, auth/pacing boundaries, execution-mode restrictions and settings pinning are unchanged. No public-API steering expansion, simultaneous steer/inject mode, dependency change, generated bundle, helper workflow or patch payload is included in this feature diff.

Configuration and live comparison

Use the existing opt-in configuration (websockets: true, codexNativeSteering: true) and restart before a fresh turn. There is no new flag. Disabling steering and restarting rolls back without deleting account or conversation files.

The Codex integration guide now includes a read-only direct-versus-proxied smoke procedure using the same supported client/model/account in separate test conversations. It explicitly distinguishes queued acceptance from a created successor and records only timing/state, not credentials or private bodies. That live procedure has not been executed here: this environment has neither an authenticated Codex installation nor a live compatible backend. No credentials or paid model calls were requested or used.

Verification

Exact source identity

• Published feature head: 77c65e1a9 — maintainer replay of this PRs commits onto dev after #4861 landed as a squash (pre-replay head 80cc768; stability delta unchanged). The content landed on dev via #4911 (f671934`).
• Source tree: 238a90f4abce838e7546a032188587f445fe046a.
• Parent feat(responses): extend native result continuations and preserve hosted output #4861 head, merged into this branch: 73eb1f4cdca57ee657a3de30f10af76edba24c86, which carries upstream dev eca65bd350d77c407f84a10514a2ab18d711052d via the stack cascade. The tested tree matches the tree dev would receive.
• Stability-only delta: 27 files, 516 insertions, 53 deletions (unchanged by the re-cascade). The diff against dev also contains the unmerged parent chain (52 files, 3,445 insertions, 34 deletions) and is not this isolated delta.

Current-source hosted run: https://github.com/luvs01/opencodex/actions/runs/35228691956 (in progress on the published head; prior head runs: 35212669471, 35203148625, 35185262651).

• Re-cascade verification on the merged head 80cc76873 (Bun 1.4.2): bun x tsc --noEmit exits 0 and the five ws-* steering/injection/continuation/upstream/failure-stage files pass 166 tests locally.

All three operating-system jobs and the documentation job reconstructed and asserted the exact feature commit/tree. All four downloaded ZIP digests match GitHub's SHA-256 values, and each artifact names that same source identity. A separate gated publication job pushed only the verified new contributor branch, without force, and the branch head was read back afterward. Application/dependency code did not execute with publication credentials.

Check	Result
New steering deadline/replay regressions	28 pass, included in the focused total
Focused steering/injection/result/shared-transport set, Linux	543 pass, 1 existing conditional skip, 0 fail
Same focused set, macOS	543 pass, 1 existing conditional skip, 0 fail
Same focused set, Windows	543 pass, 1 existing conditional skip, 0 fail
Runtime	Project-pinned Bun 1.4.0 on all three operating systems
TypeScript, privacy, architecture, file-size and whitespace gates	Passed on all three operating systems
Documentation build	449 pages, passed without deployment
Guarded publication	Passed on the same tested source

Each focused run covers 14 files and 3,203 assertions. The one skip is the existing older-runtime HTTP fallback case, not a newly skipped regression. The complete repository test suite/release matrix was not run in this author workflow.

The deadline tests use a deterministic monotonic-clock/timer fixture with spies restored in finally. They cover continued output, later submissions, oldest-ack settlement, repeated pending events, early saved results, a rejected steer after continuation dispatch, wall-clock jumps, overdue-but-not-yet-fired callbacks, ordinary inactivity, safe-boundary waiting and disposal. Replay tests cover completed/incomplete/failed sparse terminals, duplicate/conflicting content/order and the unchanged byte budget. A real handler/auth/dispatch/replay fixture verifies that the next normal request includes missing encrypted reasoning and tool-call history while the downstream terminal remains unmodified. All transports, credentials, tool results and approvals are synthetic.

Negative control: restoring the parent channel/replay implementations made 24 of the 28 new cases fail, while four controls still passed. Restoring the changes produced 28 pass / 0 fail, and the final published bytes were rechecked. Initial broader validation caught the circular dependency and a changed timeout-message expectation; the helper was decoupled and the original compatible message restored. No existing assertion, file-size cap or retry guard was relaxed.

Local supplementary checks used cached public dependencies and Bun 1.4.2: the same 543-test scope, typecheck, privacy, structure, ratchet and diff checks passed. A separate test:changed attempt stopped at missing dependency installation prerequisites after the bounded environment timeout; its selected tests did not run and are not reported as passing. Hosted evidence above uses the actual project-pinned runtime instead.

Remaining gates — keep Draft

Parent-chain integration, latest-base reconciliation, complete repository/cross-platform CI and independent maintainer/security review remain open. Live Astra/ChatGPT/Codex App/CLI compatibility and direct-versus-proxy behavior are not certified by synthetic fixtures. This PR does not change production runtime settings, approve upstream workflows, purchase credits, merge or deploy anything.

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.

Existing ownership/auth/pacing/privacy contracts were checked; the unchecked security box reserves independent review, rather than self-certifying the long-lived response-control surface.

Review readiness checklist

• All CI tests are green on my local testing.
• I pushed my PR to the latest dev commit.
• I resolved all correct Codex and CodeRabbit findings. Follow-up commits on this head: a16b26a0e validates native-control settings before superseding the active turn, a9b32021e rejects malformed output_index in steering replay, 12933bf79 caches the parsed base frame, d0a449ee2 aligns docs.
• My PR is ready for review.

Remaining gates: fork CI on the re-cascaded head 80cc76873 is in progress — https://github.com/luvs01/opencodex/actions/runs/35228691956. Fork workflow_dispatch runs always cancel on the 30-minute macos-control job; the meaningful signal is every other lane green.

Publication readback confirms 7b548ad, currently open/Draft and mergeable. All four author artifact ZIPs match their GitHub SHA-256 digests and identify tested source tree 044b8eee5c08d327ef1f0697a766d05ed93bf2bb. Parent #4861 has been linked without modifying its code or readiness state.

The scoped author matrix succeeded on all three platforms, including 543 pass / 1 existing conditional skip / 0 fail per OS, static gates and docs. This is not full-repository or live-backend certification.

New-head upstream checks are action_required, rather than passing or assertion failures:

• Cross-platform CI: https://github.com/lidge-jun/opencodex/actions/runs/35185629353
• React Doctor: https://github.com/lidge-jun/opencodex/actions/runs/35185629259

Maintainer action is needed to run these upstream checks. Keep Draft pending parent/current-base integration, full CI, independent review and the documented live direct-versus-proxy comparison. No automatic retries, model/API routing changes, real credentials or paid model requests were introduced.

- Around line 888-889: Update the opening guidance around the steering options
to explicitly require the canonical ChatGPT forward route, rather than referring
broadly to any compatible native OpenAI model. Keep the existing configuration
and restart instructions, and ensure users are directed away from public API or
other provider routes that reject response.steer.
- Around line 916-917: Update the pending-controls documentation near “resubmit
tools or steering text” to describe deadlines as fixed absolute limits rather
than inactivity-based timeouts. State that submitted controls and successor
operations retain their original deadlines, later output or steering does not
extend them, and delivery becomes unknown after expiry; preserve the 90-second
and 30-minute limits.

In `@docs-site/src/content/docs/reference/configuration/server.md`:
- Around line 577-589: Reduce the configuration section to a brief scope summary
covering the relevant behavior, and retain the existing links to the canonical
continuation and steering-deadline guidance. Remove the duplicated policy
details from the text while preserving the links and their destinations.

In `@src/server/index/websocket-handler.ts`:
- Around line 221-233: Construct and validate the native steering control before
calling ws.data.cancel?.() or clearing ws.data.nativeSteering in the
response-create handling flow. If NativeInjectionChannel or
NativeSteeringChannel construction fails, send the existing 400 error and return
without affecting the active turn; preserve the current supersession and
admission order for valid controls.

In `@src/server/responses/codex-ws-exchange.ts`:
- Around line 352-353: Cache the parsed JSON base for the exchange instead of
parsing frameText inside each sendControl continuation. Hoist
JSON.parse(frameText) into the enclosing initialization flow, reuse the cached
base when constructing outgoing, and retain the existing fresh object spread so
the cached value is not mutated.

In `@src/server/responses/native-steering-replay.ts`:
- Line 96: Update the response.output_item.done handling branch in the steering
replay logic to explicitly validate output_index and throw or reject malformed
values instead of silently skipping them. Preserve normal replay behavior for
safe integer indices, matching the validation behavior used by injection replay.

설명

이 PR은 luvs01이 올린 Draft이고, 아직 안 합쳐진 부모 체인 #4861 → #4858 → #4782 위에 얹은 안정성 전용 자식이다. 지금 리뷰 기준인 dev tip은 #4862 머지 커밋 e18ca246305bd8fc2b266bdb0ff287c6b25f6bd4 (package 2.58.0, subject: perf(cli) stop config show from importing the connect graph) 이다. 작성자가 명시한 stability-only 비교는 부모 tip b00654b368772f08c3bc68ce84b57fafc6305bc8 → 자식 head 7b548ad85e8f2a6af313198fa68a4111003cbb05 (25 files / +496 / −41) 이고, GitHub가 보여주는 dev 대비 전체 diff는 부모 스택까지 한꺼번에 잡힌다. compare 기준으로는 tip 대비 ahead 9 / behind 4 로 diverged 상태다.

현재 checkout(/home/box/developer/opencodex on dev)에는 아직 src/server/responses/native-steering*.ts / native-injection*.ts 자체가 없다. 이 자식이 부모 위에 새로 넣는 핵심은 두 가지다. (1) src/server/responses/native-steering.ts 에서 미확인 steer마다 고정 90초(NATIVE_STEERING_WAIT_MS) absolute deadline을 잡고, ended parent의 successor 90초 / 첫 pending의 tool·approval 30분(NATIVE_STEERING_TOOL_WAIT_MS) / continuation dispatch 후 90초를 서로 연장하지 않게 분리한다. nextDeadline + assertTimely + armTimer 로 늦은 프레임이 만료된 작업을 구하지 못하게 동기 검사하고, expire는 unknown delivery 한 번만 보고 자동 재전송·도구 재실행·계정 전환을 하지 않는다. (2) src/server/responses/native-steering-replay.ts 가 터미널 output 이 비어 있지 않다는 이유만으로 completed wire item을 버리지 않고, #4861 의 nativeResponseOutput (src/server/responses/native-response-output.ts) 으로 sparse terminal을 reconcile 한다. fingerprint/record 구현은 src/server/responses/native-response-json.ts 로 빼서 injection protocol이 같은 헬퍼를 re-export 하게 해 import cycle을 피한다.

왜 중요한가: 최근 dev tip #4862 는 cold CLI import를 줄이는 쪽이고, #4860/#4846 은 행동 계약(oracle)을 소스 모양 대신 신호로 고정하는 쪽이다. 이 자식은 그 연장선에서 시간·재생 계약을 고정한다. “큐에 넣었다”와 “후속이 실제로 시작했다”를 문서(docs-site/.../codex-integration.md 의 Steering confirmation deadlines)에서 구분하고, 타임아웃을 거부가 아니라 delivery unknown으로 적어 자동 재전송을 막는다. 테스트는 tests/responses/ws-steering-stability.test.ts 28건 + focused steering/injection set 543 pass(작성자 주장, 핀 Bun 1.4.0) 이고, negative control로 부모 구현을 되돌리면 24/28이 깨진다고 적었다. 방향·경계·테스트 밀도는 좋다.

다만 Draft로 둘 이유가 그대로다. 부모 #4861/#4858/#4782 통합, 최신 dev(e18ca2463…, 그 사이 #4862/#4860/#4859 등) rebase, full matrix, 독립 보안 리뷰, live Astra/ChatGPT 스모크가 남아 있다. 보안 체크박스도 비어 있다. 이전에 #4861 은 63/80 KEEP Draft, #4858 은 70/80대였다. 이 안정성 조각만 보면 품질이 높지만 부모 없이 단독 머지할 수 없고 tip도 4커밋 뒤처져 있어서 완성도 점수는 중간대에 둔다. types.ts/config.ts split 경로(src/types/config.ts + src/config/schema/config-schema.ts 의 default-off 플래그)는 맞게 탔고, 루트 barrel을 깨서 close-don't-rebase 할 대상은 아니다.

라인 단위 / 경로 단위 문제

PR base vs 현재 tip - 자식 head 7b548ad85e8f2a6af313198fa68a4111003cbb05 는 부모 b00654b… 위에만 쌓여 있고, 현재 dev e18ca2463… (#4862 포함) 과의 latest rebase/충돌 검증이 이 PR 본문에 없다 (작성자도 7a29e7b… 관찰만 적고 최신 rebase를 주장하지 않음)
src/server/responses/native-steering.ts - nextDeadline 이 unacknowledged[0]만 보고 큐 뒤쪽 steer deadline을 직접 합치지 않는다. FIFO ack 가정이 깨지면 뒤쪽 absolute deadline이 타이머에 안 잡힐 수 있는지 한 번 더 확인이 필요하다
src/server/responses/native-steering.ts - assertTimely / armTimer 경합 방지는 좋지만, expire 메시지가 상위 WS/클라이언트에 어떤 프레임(close vs error vs unknown)으로 나가는지 이 파일 단독 diff만으로는 끝까지 안 읽힌다
src/server/responses/native-steering-replay.ts - nativeResponseOutput(this.outputItems, response.output) 로 sparse terminal을 맞추는 방향은 #4861 과 일치한다. 다만 conflict throw가 steering owner에서 사용자-visible 결과로 어떻게 바뀌는지 behaviour oracle이 stability 테스트 밖에 더 있는지는 이 diff만으로 단정하기 어렵다
src/server/responses/native-response-json.ts - record/fingerprint를 injection과 공유하도록 뺀 것은 cycle을 피하는 좋은 구조다. 다만 injection 쪽 public alias(injectionRecord/injectionFingerprint) 호환을 깨는 소비자(외부 테스트/포크)가 없는지 layout/source-oracle 등록만으로 충분한지 메인테이너가 한 번 보면 좋다
src/types/config.ts / config-schema - 플래그 자체는 부모 스택과 같고 split 경로를 맞췄다. 스키마 .catch(false) 로 잘못된 타입이 조용히 off가 되면 운영자가 true를 쳤는데 꺼진 것처럼 보일 수 있다 (부모 리뷰와 동일 잔여)
security checklist - 본문이 보안 박스를 비워 둔 것은 정직하다. long-lived response-control + replay journal은 독립 보안 리뷰 없이 Ready로 올리면 안 된다
검증 범위 - focused 543 + 28 new는 설득력 있지만 full matrix·live 인증은 아니라고 적었다. 부모 land 전 단독 green으로 취급하면 안 된다

메인테이너의 판단이 필요한 지점

• #4782 → #4858 → #4861 → 이 #4864 를 각각 land할지, 안정성까지 묶은 하나의 landing PR로 갈지
• 90초 ack / 30분 tool wait 숫자를 제품 기본값으로 굳힐지, 설정 키로 뺄지 (이 PR은 상수만 둔다)
• sparse terminal reconcile 실패를 hard-fail로 둘지, 관측/로그 후 degrade 옵션을 줄지
• 보안 리뷰를 머지 전 필수 게이트로 둘지, Draft 유지 동안 별도 패스만 받을지

너의 추천

KEEP Draft. 닫지 말고 부모 #4861/#4858/#4782 와 같이 두되, land 계획에 최신 dev (e18ca2463…, #4862 포함) rebase/충돌 해소를 묶을 것. types/config split에 의해 무효화되지는 않으니 close-don't-rebase 대상은 아니다. Ready 전환 전: (1) 부모 통합, (2) 독립 보안 리뷰, (3) expire/reconcile fail이 사용자 프레임으로 어떻게 보이는지 behaviour oracle 한 줄 보강. 지금 점수 64/80 — 안정성 delta 품질·테스트는 좋고, tip 미정렬·부모 의존·보안 미완으로 머지 직전은 아님.

The remaining implementation is now in #4868, based on this exact 7b548ad8 head and integrated without conflicts with dev e18ca246.

It adds bounded/validated generation-setting overrides in explicit saved-result continuations (normal provider pins/caps/capability policy still applies), native steering for explicitly configured canonical public API WebSockets, and an executable direct-versus-loopback-proxy probe that defaults to offline/plan-only and requires explicit usage consent for live calls. No model/account switch, automatic retry, arbitrary tool execution or mixed-mode support is introduced.

The exact runtime source f3dc8eab passed 607 tests with 1 existing conditional skip and 0 failures on each of Linux/macOS/Windows, plus production/probe typechecks, privacy/structure/size checks and a 449-page documentation build. Unlike earlier scoped-only follow-ups, the unchanged full CI matrix was actually dispatched at https://github.com/luvs01/opencodex/actions/runs/35190205238 ; its final result remains separate from the scoped pass.

The fixed-deadline documentation finding is corrected in the child; a docs-only refinement explicitly enumerates both routes now supported by the child and consolidates configuration prose under canonical links. Those child changes do not make this parent's older wording fixed, so existing parent review threads are left open. Parent code and readiness state are unchanged.

Reviewed as the current stack tip (audit: #4882, contract verdicts in 020_integration_contract.md). The deadline rework is the right shape: replacing the re-armable wait() with absolute per-stage deadlines closes the case where a client that keeps sending controls extends its own window indefinitely, and assertTimely() closes the race where a frame arrives after a deadline passed but before its timer fired. expire() settling exactly once and reporting unknown delivery, rather than retrying or synthesizing a server rejection, is the behavior the rest of the stack needs. Two points.

1. This branch is two commits behind #4861.

Base is b00654b368, which is #4861's feature commit, not its head 59a1d6357e. So 4670525d48 ("reject continuations that omit pinned injection settings") and 59a1d6357e ("refund exact injection batch bytes") are not in this branch, and nothing has been built or tested on the combination dev will actually receive. A squash merge in #4861 → #4864 order will not revert them, since neither touches a line this PR edits, but that is an accident of the diff rather than a verified combination — and the omitted-key fix is exactly the settings pin that this PR's bounded continuation path depends on. A rebase onto #4861's head before this is treated as the tip would make the tested tree and the merged tree the same thing.

2. Every stage is bounded; the owned connection is not.

The per-stage numbers are all finite: 90 s per unacknowledged steer, 90 s for an automatic successor, 90 s for a sent continuation, NATIVE_STEERING_TOOL_WAIT_MS = 30 minutes for a server-requested required-input wait, and stallTimeoutSec (default 300 s) of stream idle. What has no cap is their composition. MAX_NATIVE_STEERING_RESPONSES allows 128 responses on one owned connection, and each may legitimately consume its own idle and required-input waits, so a single downstream turn can hold one physical socket — and, by C1, one pinned credential that cannot rotate because the channel deliberately never re-enters account selection — for far longer than any ordinary turn, on the order of tens of hours in the worst case, without any individual deadline being violated.

That is not a defect in this PR's timer logic, and it may well be the intended tradeoff for a long agent session. But it is the operational number the activation decision needs, and it is not currently stated anywhere in the configuration docs the stack adds. Either an absolute lifetime bound on the owned connection, or an explicit statement of the worst case next to the other limits in the codexNativeSteering documentation, would make the cost visible to whoever turns the flag on.

Both points addressed in 6d13e1071 ("Merge #4861 head and document the owned-connection worst case").

1. Branch now contains the #4861 head. I merged 59a1d6357e into this branch rather than rebasing, so the published history stays intact and the tip now carries 4670525d48 and 59a1d6357e. The merged combination is the tested tree: the ws-native injection/continuation/steering files pass 120 tests on this exact head, including the pinned-settings rejection cases. One conflict in server.md was resolved by keeping this branch's consolidated wording with the parent's site-relative link.

2. Worst case is now documented. The steering deadlines section in codex-integration.md now states explicitly that the owned connection has no absolute lifetime cap: up to 128 responses may share it, each consuming its own acknowledgement, successor, idle and required-input waits, composing to a worst case on the order of tens of hours with one pinned credential that cannot rotate.

Re-cascaded onto new parent #4861 head 73eb1f4cd (carrying upstream dev eca65bd35); new head 80cc7687351dff4dd814d913b460bbe2799e13d3. Merge resolutions preserve the channel-create-before-cancel ordering, the let base/??= parsed-frame caching, and the parent's nativeControl naming. Local on the merged head: bun x tsc --noEmit exits 0 and 166 tests pass across the five ws-* files. Fork CI in progress: https://github.com/luvs01/opencodex/actions/runs/35228691956 (fork dispatch runs always cancel on the 30-minute macos-control job; the meaningful signal is every other lane green).

Merging with maintainer admin rights.

This head is the PR's own commits replayed onto current dev after its parent #4861 landed as a squash, with the replay verified before the push: identical file set and status against dev compared with the pre-rebase diff against the parent head, patch bodies identical once index lines are excluded, authorship unchanged, and both feature flags still default-off.

Any non-green entry is the contributor readiness gate, whose local-CI box is an author attestation a fork contributor cannot satisfy against repository CI, or a cancelled macOS capacity job, which produced no result rather than a failure.

[lidge-jun]

Landed. This work is on dev as f671934f02 and shipped in 2.58.0.

It could not be merged from here: the contributor readiness gate held this pull request in draft and the API refused to mark it ready, so the identical tree at 77c65e1a99 was carried through #4911 with a Co-authored-by trailer naming you, and the commits kept their original authorship. Closing this one because the change is already integrated, not because it was rejected.

Thank you — the finite steering deadlines and the sparse-replay-output preservation both went out as written.
