fix(combos): hold a spent usage window for ten minutes, not sixty seconds - #5874
vadymhimself wants to merge 5 commits into
Conversation
The ChatGPT Codex backend reports a depleted plan window as HTTP 502 `upstream_server_error` carrying the prose `The usage limit has been reached`, never the documented 429. `isProviderScopedQuotaCap` is gated on `status === 429`, so an exhausted window never matched it, fell through `coolComboTarget`'s duration chain to `DEFAULT_COOLDOWN_MS`, and the dead account was re-offered 60 seconds later where it failed identically. Over 72 hours of one production combo that produced 942 doomed sends (847 `openai`, 95 `combo`), each surfacing to the caller as `adapter_eof`, plus 94 downstream `503 No available targets`. The combo hops and the request still returns 200, so the cost is wasted upstream calls and latency rather than a user-visible error, which is why it went unnoticed. The change is duration only. `isAccountWindowExhausted` is read in exactly one place, the final fallback arm of the `cooldownMs` chain, and selects `MAX_COOLDOWN_MS` (ten minutes, already the clamp on this path) instead of `DEFAULT_COOLDOWN_MS`. A status-blind prose match is safe for choosing how long to wait; it would not be safe for choosing what to black out, so `isProviderScopedQuotaCap`, `comboFailureCooldownScope`, `comboFailureDecision` and `isTransientRequestRateLimit` are untouched and a Codex 502 still resolves `target` scope and `hop` through the existing `status >= 500` path. A server-stated `Retry-After`, a quota reset instant and an operator's configured `cooldownMs` all sit earlier in the `??` chain and still win. Ten minutes rather than a pin to the advertised reset is deliberate: quota commonly frees earlier than advertised (lidge-jun#433), and a longer hold would skip a target that had already recovered. This changes one existing expectation. `combos.test.ts` asserted that code `1308` / `Usage limit reached for 5 hour` stops cooling at +60,000 ms. That assertion arrived in 6b2dfde (lidge-jun#3294) as the negative control proving 1308 does NOT take the new 5-second request-rate cooldown, so the 60-second value was a side effect of that contrast rather than a position on exhaustion. 1308 is itself a 5-hour usage window, so 60 seconds re-probes it about 300 times before it can possibly succeed. The test is updated, not removed: the contrast it was written to prove is preserved (1308 is still not `COMBO_REQUEST_RATE_COOLDOWN_MS`), it now holds the ten-minute exhaustion cooldown. See lidge-jun#5860, where this expectation change was put to maintainers before the patch was sent. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

CodeRabbit review on lidge-jun#5874. A code-only `1308` carried no prose, so `isAccountWindowExhausted` missed it and the target took the 60-second default — the exact re-send loop this branch exists to stop, on the one code the branch already re-argues. `1308` joins ACCOUNT_EXHAUSTION_CODES. The rest of QUOTA_LIMIT_CODES stays out on purpose: those are quota-limit codes whose window length this gateway has no evidence for, and holding them long would strand a target that may clear sooner. Also: the two precedence tests asserted only the expiry instant, so an implementation that expired early would still have passed; they now assert just-before-expiry too. And the combos guide documents the ten-minute hold, how a spent window is recognised, and where it sits in the precedence chain. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

리뷰 · 우선순위 61 / 80이 PR은 콤보가 이미 바닥난 계정을 1분마다 다시 부르는 일을 줄인다. ChatGPT Codex는 사용량 창이 떨어지면 설명서에 있는 429를 주지 않는다. 502를 주고, 글에는 "The usage limit has been reached"(사용량이 한도에 닿았다)라고 적는다. 지금 코드는 "상태가 429이고, 월간 한도다"일 때만 특별 취급한다. 그래서 이 502는 그 조건에 안 맞아서, 기본 휴식 60초로 떨어진다. 60초 뒤에 같은 계정을 또 부르고, 또 실패한다. 작성자가 72시간 기록을 세어 보니 이런 헛호출이 942번이었다. 콤보는 다음 건강한 대상으로 넘어가서 사용자에게는 성공(200)으로 보이기 때문에, 낭비와 지연만 남고 에러는 잘 안 보였다. 고친 것은 쉬는 시간뿐이다. 계정이 바닥난 것으로 보이면 60초 대신 10분을 쉰다. 알아보는 방법은 코드 세 개( 더 정확한 신호가 있으면 그 신호가 이긴다. 서버가 준 Retry-After, 리셋 시각, 운영자가 적은 cooldownMs는 예전과 같다. 누구를 쉴지도 안 바뀐다. 502는 계속 그 대상만 쉬고, 다음 대상으로 넘어간다. 테스트 하나도 기대가 바뀌었다. 코드 1308은 5시간 사용량 창이다. 예전 테스트는 60초만 쉰다고 했다. 이제는 10분을 쉰다고 한다. 1308이 요청 속도 제한(5초)은 아니라는 점은 그대로다. src/combos/failover.ts:233 - 가이드는 5초 휴식(코드 1302, 1305)이 10분 휴식보다 강하다고 적는다. 코드는 반대로, 바닥남 검사를 먼저 한다. 1302인데 글에 사용량 한도 문장이 같이 있으면 가이드는 5초, 코드는 10분이다. src/combos/failover.ts:325 - 글 검사가 넓다. "usage limit reached"가 들어 있기만 하면 상태와 상관없이 10분이다. "monthly usage limit reached"(월간 한도)도 여기 걸린다. 월간 한도는 원래 같은 공급자 전체를 쉬는 다른 길인데, 쉬는 시간만 60초에서 10분으로 늘어난다. Codex 502만 고치려던 것보다 범위가 크다. src/combos/failover.ts:234 - 10분 값이 docs-site/src/content/docs/guides/combos.md:330 - 가이드는 알아보는 글을 "usage limit reached"만 적는다. Codex가 실제로 보내는 글은 "usage limit has been reached"다. 코드는 둘 다 보는데, 가이드만 읽으면 실제 문장은 빠지는 것처럼 보인다. docs-site/src/content/docs/guides/combos.md:337 - 우선순위 문장이 코드와 순서가 반대다. 5초가 10분보다 앞에 적혀 있다. 메인테이너의 판단이 필요한 지점 1308은 5시간 창인데 휴식은 10분이다. 작성자 말은 이렇다. 이 길의 상한이 이미 10분이고, 한도는 광고보다 일찍 풀리는 일이 있다(#433). 리셋 시각에 못 박으면 이미 살아난 대상을 너무 오래 건너뛴다. 10분이어도 5시간 안에 약 30번은 아직 헛호출이다. 60초(약 300번)보다는 훨씬 적다. 이 기대 변경을 받을지 정해야 한다. 테스트는 #3294에서 "1308은 5초짜리가 아니다"를 보여 주려고 60초를 써 둔 것에 가깝다.
너의 추천 누구를 막을지는 그대로 두고 쉬는 시간만 늘린 점이 안전하다. 머지 전에 가이드 순서를 코드와 같게 고치는 게 좋다. 월간 한도 문장이 10분에 섞이는 것은 테스트로 고정하거나, 문장 검사에서 빼는 게 좋다. 10분에는 이 댓글은 grok-bot이 작성했습니다 |
…lback CodeRabbit review on lidge-jun#5874. The guide listed the 5-second request-rate fallback before the ten-minute usage-window hold, but `coolComboTarget` tests `isAccountWindowExhausted` first.

The runtime selects the 10-minute hold when a usage-window exhaustion signal matches, before the request-rate fallback. The
cooldownMsrow at Line 583 and the troubleshooting text at Lines 608–610 still say that an unset value falls back to 5 seconds for request-rate codes and 60 seconds otherwise. Those descriptions give users the wrong duration for a recognized usage-window failure.

CodeRabbit review on lidge-jun#5874. The translated guides still described the old fallback (5 s for 1302/1305, 60 s otherwise), which is now wrong rather than merely stale. ja, ko, ru and zh-cn are updated to match the English page. fr, tr and zh-tw do not carry this passage and are untouched. Reviewing that also exposed two English passages my earlier commit missed -- the `cooldownMs` config-table row and the "all targets ineligible" troubleshooting answer -- which described the fallback without the ten-minute usage-window case.

CodeRabbit review on lidge-jun#5874. The two predicates overlap: `1302` is a request-rate code, but usage-limit prose says the window is spent. `coolComboTarget` tests exhaustion first, so the ten-minute hold wins. The combos guide states that; nothing enforced it, so reordering the arms would have silently regressed the documented behaviour. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Implements the fix proposed in #5860. That issue asks a design question first, and this PR does not presume the answer — it changes an existing expectation, so please read the "What this changes about 1308" section before the diff. If you would rather keep 60 seconds for a spent window, close this and I will adapt downstream instead.
Summary
The ChatGPT Codex backend reports a spent plan window as HTTP 502
upstream_server_errorcarrying the proseThe usage limit has been reached— not the documented 429.isProviderScopedQuotaCaprequiresstatus === 429 && (gousagelimiterror || "monthly usage limit reached"), so an exhausted window never matches it, falls throughcoolComboTarget's duration chain toDEFAULT_COOLDOWN_MS, and the dead account is offered again 60 seconds later — where it fails identically, for the life of the window.Production ledger over 72 hours on a two-target
failovercombo: 942 doomed sends (847openai, 95combo), each surfacing to the caller asadapter_eof, plus 94 downstream503 No available targets for combo.This is invisible in normal operation because the combo hops to a healthy target and the request still returns 200. The cost is wasted upstream calls and latency, not visible errors, which is why it persisted.
The change
A status-independent exhaustion predicate, used only to choose the cooldown duration:
An exhausted window takes
MAX_COOLDOWN_MS(10 minutes, already the clamp on this path) instead of 60 seconds.Ignoring HTTP status is the entire point — the status is 502 rather than 429, which is why the existing predicate cannot see this. That is safe for choosing how long to wait and would not be safe for choosing what to black out, so the predicate is read in exactly one place: the duration fallback.
isProviderScopedQuotaCap,comboFailureCooldownScope,comboFailureDecisionandisTransientRequestRateLimitare byte-identical todev; a Codex 502 still resolves totargetscope andhopthrough the existingstatus >= 500path.Everything more specific than a guess still outranks the new default, unchanged and earlier in the
??chain: a server-statedRetry-After, a reset instant, and an operator's explicitcooldownMs.Ten minutes rather than a pin to the advertised reset is deliberate: quota commonly frees earlier than advertised (#433), and a longer hold would skip a target that had already recovered.
What this changes about 1308 — the part needing your ruling
tests/codex-integration/combos.test.tshadkeeps the default cooldown for usage-window 1308, asserting code1308/Usage limit reached for 5 houris still cooling at +59,999 ms and not at +60,000 ms. Our predicate matches that prose, so the expectation changes and the test is renamed toholds the exhaustion cooldown for usage-window 1308.I believe that is the consistent outcome rather than a regression: 1308 is a five-hour usage window, so a 60-second cooldown re-probes it roughly 300 times before it can possibly succeed. But that test arrived in
6b2dfde11(#3294) as the negative control proving 1308 does not get the new 5-second request-rate cooldown, so the 60-second value may have been incidental to that contrast rather than a deliberate position. Only you can say which.The test is updated and commented rather than deleted, and it still pins the contrast that #3294 cared about — 1308 is not a request-rate failure — just at the longer duration.
Verification
Regression test added covering the Codex 502 + prose case, the structured codes, an unrelated 502 still taking the 60-second default, an explicit server
Retry-Afterstill outranking the new default, and the scope/hop invariant.Proven red before green: reverting only the fallback arm fails the new cases; restoring it passes them.
3 files, 98 insertions, 8 deletions. Rebased onto the current
devtip.A sibling case with no such collision — permanent credential and billing failures in
PROVIDER_SCOPED_FAILURE_CODEStaking the same 60-second default — is #5859.Refs #5860.
