Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughCombo failover now applies a 10-minute target cooldown when failure messages indicate exhausted usage limits, including HTTP 502. Upstream retry/reset signals and configured cooldowns retain precedence. Tests and runtime guidance cover the fallback; localized combo guides document it. ChangesUsage-limit cooldown

Keep request-rate codes ahead of the usage-message fallback.
When a reachable HTTP 429 has upstream code 1302 or 1305 and a message containing usage limit reached or usage limit has been reached, the new regex selects the ten-minute cooldown before isTransientRequestRateLimit can select the established five-second cooldown. Check the request-rate classification first.

리뷰 · 우선순위 40 / 80이 PR은 콤보가 고른 계정의 사용량이 떨어졌을 때, 그 계정을 다시 부르기 전 쉬는 시간을 60초에서 10분으로 바꿉니다. 베이스는 Codex는 사용량이 끝났다는 소식을 HTTP 502와 영어 문장 "The usage limit has been reached"로 보냅니다. 코드는 HTTP 429만 사용량 끝으로 보고 있었습니다. 그래서 502는 평범한 짧은 실패가 되고, 60초 뒤에 같은 계정을 또 불렀습니다. 이슈 #5860은 이렇게 실패한 호출이 72시간 동안 942번이었다고 적습니다. 옆의 멀쩡한 대상이 답을 만들어서 사용자는 성공을 볼 수 있지만, 죽은 계정으로 가는 호출은 계속 나갑니다. 고친 자리는 src/combos/failover.ts:234 - 같은 일을 하는 PR #5874가 이미 열려 있습니다. #5874는 리뷰 준비 상태이고 체크리스트 4칸이 채워져 있습니다. 문장과 함께 docs-site/src/content/docs/ko/guides/combos.md - 영어 안내와 코드는 10분 검사가 5초짜리 요청 속도 제한보다 앞입니다. 한국어, 일본어, 러시아어, 중국어 안내는 10분을 맨 뒤 60초의 한 종류로 적어서, 5초 검사가 먼저인 것처럼 읽힙니다. docs-site/src/content/docs/tr/guides/combos.md - "10 dakika)lik"으로 붙어 있습니다. 맞는 꼴은 "dakikalık"입니다. tests/codex-integration/combos.test.ts - 코드 1308과 문장 "Usage limit reached for 5 hour"의 쉬는 시간을 60초에서 10분으로 바꿔 놓았습니다. 이슈 #5860은 이 60초가 일부러 정한 값인지, 5초 테스트의 반대편에 그냥 남은 값인지 먼저 정해 달라고 했습니다. 메인테이너의 판단이 필요한 지점 설정한 cooldownMs가 10분보다 앞인지도 정할 일입니다. 지금은 5초로 적어 두면 사용량이 끝나도 5초 뒤에 다시 부릅니다. 테스트가 그 순서를 고정합니다. 942번 같은 헛호출을 짧은 설정값 아래에서도 막으려면 순서를 바꿔야 합니다. 코드 1302나 1305이면서 문장에 "usage limit reached"가 있으면 이 PR은 10분을 고릅니다. 5초 속도 제한보다 앞선 자리이기 때문입니다. 영어 안내와 #5874는 그 순서를 맞다고 적습니다.

Adopt upstream v2.67.0 whole; fork package line moves to 2.68.0. No fork src file overlaps upstream's 48 changed src files. zh-TW docs: two content conflicts resolved against the English source, a duplicate section from an upstream heading rename folded, and the new remote-workspace RPC section translated. release-outcome-report test follows the fork's official-repo guard on release-outcomes.

Summary
Closes #5860.
Codex upstreams frequently return HTTP 502 with
"The usage limit has been reached"or"upstream_server_error"when a subscription quota window is exhausted. Previously, this fell back to the 60s default cooldown, triggering hundreds of doomed retries during quota exhaustion.Implemented via Codex (
