Summary

  • Follow up fix(devin): wait out a stated rate-limit reset and replay the turn #5041 for the current sanitized Cognition error form: Cognition chat failed (resource_exhausted); retry after ~180s. The shared retry-delay parser now accepts the generated approximation marker after Retry-After, so the bounded Devin wrapper waits 180 seconds instead of treating the refusal as having no usable delay.
  • Re-evaluate the delay on every bounded replay. A first refusal may say reset in 35 seconds and the next may say retry after ~180s; each wait is parsed from that attempt, while the existing cumulative wait and replay ceilings remain unchanged.
  • Preserve the same parsed delay in client cooldown metadata when the final 429 is surfaced. Approximate markers remain limited to the Retry-After form; malformed units and reset in ~... stay rejected.

Follow-up to #5041.

Verification

  • bun test tests/server/retry-delay-hardening.test.ts tests/server/retry-after-429.test.ts tests/providers/devin-stated-reset-retry.test.ts tests/providers/devin-stated-reset-hardening.test.ts tests/providers/devin-hardening.test.ts tests/codex-integration/combo-authoritative-reset.test.ts — 132 pass, 0 fail.
  • bun run typecheck — passed.
  • bun run privacy:scan — passed.
  • bun run test:changed selected 1,140 files through the shared src/lib dependency and hit the repository's 900-second suite ceiling. Before termination it reported one unrelated pre-existing timeout in tests/server/aside-profiles-routes.test.ts (5-second timeout); the focused tests above remained green.
  • The original local bun run structure:check reported unmodified structure/ops/docs-and-release.md at 601 lines against its 600-line budget. This records that local result, not the current CI status: the exact-head CI structure gate for 5cff45fba41f1b426ca20bf7fcdb1f66c4f674de has since completed successfully.
  • Current-head Cross-platform CI run 35816902207: test 1/4 through test 4/4, gates (including typecheck and privacy scan), structure gate, docs site build, and the aggregate ci job all succeeded. Windows test shards and macOS jobs were skipped in this run; this is not a claim that those suites ran. The separate React Doctor workflow also succeeded.

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.

Summary by CodeRabbit

  • Bug Fixes
    • Approximate retry delays, such as “retry after ~180s,” are now recognized so the app can wait for the stated duration before retrying.
    • Consecutive retry failures use the latest stated delay. Approximate reset times remain excluded when they don’t indicate a retry-after duration.
  • Documentation
    • Clarified that pre-output rate-limit responses may be retried up to twice after the full stated delay, subject to a cumulative wait limit. If retries are exhausted, the final response retains the stated delay as its cooldown hint.

이 PR은 Devin이 밖에 내보내는 에러 글 retry after ~180s를 다시 초로 읽게 만듭니다. 물결표는 우리가 대기 시간을 적을 때 붙입니다. 원문에서 뽑은 초는 숫자 칸 retryAfterSeconds에 따로 있고, 밖으로 나가는 글에만 ~180s가 붙습니다. 공용 파서는 그 물결표 때문에 이 글을 대기 시간으로 보지 않았습니다. 글만 보는 쿨다운은 180초 대신 기본 2초를 주거나, 쿨다운용으로는 빈 값을 냈습니다.

바꾼 코드는 파서 한 줄입니다. retry after 바로 뒤의 ~만 떼고 숫자를 읽습니다. reset in ~3분처럼 리셋 문장의 물결표는 예전처럼 거절합니다. 테스트는 파서, 클라이언트 쿨다운 도우미, Devin 재시도 래퍼 세 곳입니다. 뒤 커밋 979e209는 문서에 이렇게 적습니다. 마지막 429는 그 초를 클라이언트 쿨다운 힌트로 남기고, 물결표는 헤더가 아닌 대략값입니다. 베이스는 dev입니다.

라인 - src/adapters/devin/cloud-direct/chat.ts 1560-1562와 docs-site/src/content/docs/reference/adapters.md 503-504: 코드 주석은 물결표 때문에 이 글을 다시 숫자로 읽지 못한다고 하고, 새 문서는 그 초를 쿨다운 힌트로 남긴다고 합니다. 두 문장은 반대입니다. 코드는 숫자 칸이 있기만 하면 항상 ~를 붙입니다.
라인 - src/adapters/devin/cloud-direct/stated-reset-retry.ts 115-119: 래퍼는 숫자 칸이 있으면 글을 보지 않습니다. 실제 트레일러 에러는 글과 숫자 칸을 같이 넣습니다 (chat.ts 1566-1572). 새 테스트의 exhausting()은 CloudChatError에 숫자 칸을 넣지 않습니다. "래퍼가 180초를 안 기다렸다"는 말은 숫자 칸이 빈 에러에만 맞습니다. 원문에서 초를 뽑은 거절은 이 패치 전에도 그 초만큼 잡니다.
라인 - src/adapters/devin.ts 756-766: 어댑터가 에러를 올릴 때 숫자 칸을 버리고 글만 넘깁니다. 글만 보는 쪽이 180을 못 본 이유는 여기입니다. 어댑터 에러 타입(src/types/request.ts 399-409)에는 대기 초 칸이 없습니다.
라인 - src/lib/errors.ts 529-531: 상태와 코드가 없는 에러는 파서 결과를 보고 글 끝에 Please try again in 180s를 붙입니다. Devin 거절은 상태와 코드가 있어서 이 덧붙이기는 타지 않습니다. 다른 글에 retry after ~가 있으면 탑니다.
라인 - src/lib/retry-delay.ts의 ~ 제거: 맨 앞 ~ 한 번만 뗍니다. retry after ~1 minute ~30 seconds는 60초만 남고 뒤는 버립니다. 우리가 만드는 글은 retry after ~180s 한 덩이라 지금 경로는 이 경우에 안 걸립니다.

메인테이너의 판단이 필요한 지점

물결표를 방화벽으로 둘지, 사람이 읽는 대략 표시로 둘지입니다. 새 문서는 대략 표시 쪽을 골랐습니다. 코드 주석은 아직 방화벽이라고 합니다. 어댑터 에러에는 초 칸이 없어서, 글을 파싱하는 것이 쿨다운에 180을 넣는 지금 통로입니다.

너의 추천

chat.ts 주석을 문서와 같게 고친 뒤 머지하세요. 방화벽으로 되돌릴 거면 파서 변경과 문서 커밋을 같이 빼세요. 본문의 "래퍼가 안 기다렸다"는 실제 트레일러와 다릅니다. 래퍼 테스트에는 숫자 칸을 채워, 이 패치가 고치는 곳이 resolveClientRetryAfter라는 점이 보이게 하세요. 같은 수정의 다른 열린 PR은 없습니다.

Independent review — 5cff45fba41f1b426ca20bf7fcdb1f66c4f674de

No additional blocking functional defect was identified in the current change. No source-code commit was added merely to churn an already-correct fix.

Findings

  • The generated retry after ~180s diagnostic previously lost its delay at the shared message-parser boundary. Removing only the new approximation-handling line reproduces undefined; current code returns 180.
  • Acceptance stays restricted to Retry-After/retry-after-style hints. Approximate reset in and try again in, repeated approximation markers, signed/exponent/clock forms, unsupported units, malformed numeric continuations, unsafe integers, and excessive component counts remain rejected in the exercised cases.
  • The existing wrapper continues to re-evaluate each refusal, prefer typed delay metadata, wait the full admitted delay, enforce the cumulative allowance and two-replay limit, stop after any output event, and honor cancellation. A 35s refusal followed by an approximate 180s refusal schedules 35,000ms then 180,000ms; a budget one millisecond below 215,000ms rejects the second wait without shortening it.
  • Final cooldown-message handling preserves numeric seconds, not the literal ~ marker, including the latest refusal after replay exhaustion.

Maintenance follow-up completed

  • Replied to and resolved the remaining documentation thread after checking that docs-site/src/content/docs/reference/adapters.md:498-507 already addresses it.
  • Corrected the Verification section to distinguish the original local structure-check failure from the now-successful exact-head CI structure gate. Historical local results were retained rather than rewritten as passes.

Verification and limitations

  • Ran a supplementary scratch harness with node --experimental-vm-modules verify.mjs under Node v22.16.0: 86 checks passed, 0 failed, including 1,200 generated approximate/unmarked parser parity comparisons.
  • The three exercised production modules (retry-delay.ts, stated-reset-retry.ts, retry-after.ts) were byte-for-byte checked against their Git blob hashes before execution. Dependency boundaries for transport/error classes/abort helpers/physical sends/header parsing/error classification were mocked; transport integration, real timers, physical-send accounting, and the full project were not exercised by this harness. The harness was not committed to the repository.
  • This environment has no Bun and cannot clone/install dependencies, so this is not a claim of a new local Bun-suite or full-project typecheck run. The pre-existing 132-test result in the PR body remains the author's earlier result.
  • Independently inspected exact-head CI run 35816902207: all four test shards, typecheck, privacy scan, structure gate, docs build, and aggregate ci completed successfully; React Doctor also succeeded. Windows test shards and macOS jobs were skipped in that run and are not counted as executed test suites.

PR left open; no merge or auto-merge action was taken.

Carries #5629. The shared retry-delay parser accepts the generated
"retry after ~180s" approximation marker after Retry-After, and the bounded
Devin replay re-evaluates the delay on every attempt within the existing
cumulative ceilings.

Folded review fixes: a repeated approximation marker ("~1 minute ~30
seconds") now rejects the hint instead of silently shortening it to the first
component, and the cloud-direct comment no longer claims the marker blocks
re-parsing.

Supersedes #5629.

* fix(responses): restore code-mode goal helpers

Carries #5659. Routed create_goal, get_goal and update_goal calls (bare or
with a provider-invented default. prefix) are accepted as nested helpers of a
genuinely declared code-mode exec and compiled to the matching
tools.<helper>(...) call instead of falling through to exec_command. A
genuinely declared bare goal tool keeps its identity, and a catalog that
declares neither the tool nor exec still fails closed.

Folded review fixes: the guard is asserted on the original unrestored wire
name, an unlisted helper-like name is proven not admitted, bare-goal
precedence is covered through full restoration, the authorization comments in
src/types/tools.ts name the goal helpers, and the codex integration guide
describes the repair.

Closes #5495. Supersedes #5659.

* fix(responses): stop combo failover once a request has spent its ambiguous replacement

Carries #5646. Once a request has spent its retryOnReset replacement, the
first send may already have run the turn, so a replacement that answers 200
and then fails with zero output must not be sent again. RequestExecutionBudget
now reports ambiguousResendSpent from the one shared grant; combo failover
stops when it is spent and settles the answer with the shared
settleOperatorReplacement rule (a resendable status becomes the replay
refusal, anything else keeps its status with the non-replayable marker). On
the direct path the streamed opaque-blob rebuild is skipped once the grant is
spent. Carried before #5633 so its WebSocket replacement row is never exposed
to the third-send gap.

Supersedes #5646.

* fix(responses): let retryOnReset replace a Codex WebSocket send that died unanswered

Carries #5633. A Codex WebSocket that opens and then closes or errors under
its create frame before any Responses event is the same unknown state as an
HTTP connection that resets before its head. For a provider that opted into
retryOnReset, the request-resend gate may now spend the request's single
replacement on it (one replacement per logical request, self-contained body
only). The exchange records the stage it reached; silence keeps its 504 and a
drop after a relayed event keeps its errored 200. Providers that have not
opted in are unchanged.

Carried after #5646, so the WebSocket replacement row inherits the spent-grant
stop. Folded review fixes: the duplicate settleOperatorReplacement import the
pair merge produced is removed, and responses-failover.md states the 2xx
replacement contract once as settled for all three replacement rows.

Supersedes #5633.

* fix(combo): fail over undeclared zero-output tools

Carries #5489 (net diff; its upstream/dev merge commit is dropped). When a
runTurn adapter's first meaningful event in a combo attempt is a tool call the
current request did not declare, the existing fail-closed refusal is projected
as a pre-commit 502 so the combo can hop to the next target with the same tool
catalog. Chat Completions and Anthropic Messages inbound requests keep their
existing behaviour.

Folded review fix: the non-streaming path now applies the same boundary as the
streaming preflight. An undeclared tool call after a replay-unsafe heartbeat
(an adapter-side effect already ran) keeps the refusal on that child instead of
sending the turn to another target. New streaming and non-streaming cases prove
exactly one dispatch; the non-streaming one fails without the gate. The combos
guide gains the hop row in every locale and responses-failover.md records the
runTurn boundary.

Related to #5407 (covers its Responses path only; the reported Claude Code
Anthropic Messages path is unchanged). Supersedes #5489.

Co-authored-by: Yu Zhang <34849476+AaronZ345@users.noreply.github.com>

* fix(combo): keep failures after a replay-unsafe side effect on their child

Found by the lane's adversarial review of the carried #5646/#5489 changes.

- A runTurn adapter that emits a replay-unsafe heartbeat (it already ran a
  local side effect, as Cursor does) and then errors or ends empty before any
  output returned a plain 502, so a combo sent the turn to the next target and
  could repeat the side effect. Streaming and non-streaming paths now mark that
  502 non-replayable, and the combo stops on the child. This predates the
  carried commits; it sits on the same boundary structure/runtime.md states.
- A scope derived from a shape-compatible budget that implements
  claimAmbiguousResend but not ambiguousResendSpent reported "not spent" after
  it claimed the grant, which would let a combo hop on a zero-output 200 from
  the replacement (a third send). Grants claimed through the bridge are now
  latched per bridged parent and visible to every sibling scope.

Both are covered by new tests that fail without the fix.

* fix(responses): let a WebSocket replacement that resets use a second grant

Review finding on #5675. With retryOnReset.replacements set to 2, a dead
Codex WebSocket spends the first grant on its HTTP replacement; if that
replacement resets before its head, the WebSocket row settled it as the
replay refusal at once, so the configured second replacement was never
reachable. The reset is the pre-header row again, so the row now asks the
same gate (and the send budget) once more and resends only when a grant
remains; with the default of one it still settles as the refusal. The loop is
bounded by the request's finite allowance.
