Summary

Co-authored-by: yxr1995-maker 257504378+yxr1995-maker@users.noreply.github.com

Verification

  • Current head 8de12699820ec88fec995e650f2bb0d127be1f65 includes the stored Pool recovery boundary repair and is awaiting its own hosted CI. Earlier green runs do not verify this head. No local tests, typecheck or build were run.

  • Independent xai/grok-4.6 plan, source/security, final and repaired-parent composition reviews passed. Earlier head1697a77486e70f7ca10009a8bc0fa065c5694d4d passed full CI34021905490: https://github.com/lidge-jun/opencodex/actions/runs/34021905490 (Linux four shards, macOS two shards, gates and npm installation). The independently reviewed fixture prerequisite passed CI34021866383 and merged as cededd5.

  • Regression coverage includes native disabled/cooldown, native model-authorization exhaustion, failed recovery/no dispatch, canonical versus noncanonical quota, eligibility/wait rules and abort during both recovery sites.

  • No local test suite, typecheck or build was run. No live Kiro request was made.

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.

The repository owner authorized admin integration without a second approval. Source #3706 remains open until this layer actually lands; original contributor credit is retained.

Summary by CodeRabbit

  • New Features

    • Mixed combos can recover encrypted tasks once and route them when no usable native target is available, if recovery is enabled.
    • Native target availability and quota handling are evaluated more accurately.
    • Client cancellations during recovery now return a cancellation response instead of an unreadable-task error.
  • Bug Fixes

    • Recovery now selects payload-compatible targets and fails closed when recovery or routing is unavailable.
  • Documentation

    • Updated configuration and encrypted-task delivery guidance across supported languages.

📝 Walkthrough

Walkthrough

Combo routing preserves canonical native-target priority, applies provider-specific quota rules, and performs one encrypted-task recovery before routed dispatch when no usable native target remains. Cancellation, fail-closed behavior, tests, and documentation were updated.

Changes

Combo recovery

Layer / File(s) Summary
Provider eligibility and quota selection
src/combos/resolve.ts, tests/codex-integration/combos.test.ts
Canonical OpenAI forward providers no longer fail selection because of cached provider-summary quota. Noncanonical providers still honor quota exhaustion. Tests cover cooldown waits and caller eligibility filters.
One-shot encrypted task recovery
src/server/responses/core.ts, tests/server/agent-task-recovery-combo.test.ts
Recovery runs after no payload-compatible native target is available. Late recovery excludes attempted targets and runs once. Abort returns 499 client_cancelled; failed recovery remains closed with existing error responses.
Pool replay and recovery validation
tests/responses/responses-pool-401-refresh.test.ts
The pool-401 harness now tracks recovery and backup dispatch. Tests cover refresh and recovery limits, canonical aliases, cancellation, persistence, backup failures, and terminal errors.
Behavior documentation and release records
devlog/_plan/260906_release_244_followups/*.md, docs-site/src/content/docs/**/reference/configuration/agents.md, docs-site/src/content/docs/guides/sub-agent-surface.md
Planning records and localized documentation describe native-target priority, opt-in recovery, fail-closed routing, cancellation handling, and no plaintext forwarding on recovery failure.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 1697a

A bounded error-response mismatch and misleading recovery documentation remain. Neither permits unreadable ciphertext dispatch or plaintext persistence, but both should be corrected.

이 PR은 release-244 플랜의 050_combo_recovery 칸입니다. 베이스가 dev가 아니라 #3753 브랜치 codex/release-244-opaque-recovery-07c0입니다. 암호화된 agent task를 읽을 수 있는 native 타깃이 설정만 되어 있고 실제로는 고를 수 없을 때(disabled·쿨다운·모델 권한 고갈 등) 한 번만 routed 타깃으로 회복하도록 handleComboResponses를 다시 짜고, canonical OpenAI forward provider는 계정/모델 선택기가 quota를 소유하게 해서 provider summary cache가 native를 미리 막지 못하게 합니다. 원본 캐리는 #3706(지금도 dev 직행 draft로 열려 있음)이고, Co-authored-by에 yxr1995-maker가 있습니다. 이 PR 자체도 draft입니다.

지금 HEAD(adb696197)의 combo 경로는 unreadableEncryptedAgentTask && !combo.targets.some(canDecryptUnreadableAgentTask)일 때만 회복을 시도합니다. 즉 native가 목록에만 있으면 회복 분기로 안 들어가고, native가 전부 막혀도 “읽을 수 없음”으로 끝날 수 있습니다. src/combos/resolve.tstargetProviderIsUsable는 disabled만 보고, pickComboTarget / pickComboTargetWithWait모든 provider에 대해 cachedProviderQuotaIsExhausted를 한 번 더 겁니다. 이 PR은 (1) 먼저 payloadEligible로 실제로 고를 수 있는 타깃을 고르고, (2) unreadable인데 pick이 없으면 한 번 더 wait-pick 후 recoverUnreadableEncryptedTask(일회 가드)로 평문 회복을 시도하며, (3) failure로 attempted가 소진된 뒤에도 같은 회복을 한 번 더 열어 줍니다. 두 회복 지점과 최종 wait 뒤에 호출자 abort면 clientCancelledResponse를 유지합니다. 실패 회복은 ciphertext를 보내거나 회복 평문을 persist하지 않는다고 본문이 못 박습니다.

quota 쪽 변경은 중요합니다. isCanonicalOpenAiForwardProvider면 provider summary exhausted로 타깃을 지우지 않고, 비canonical/서드파티만 cache로 걸러냅니다. 테스트는 tests/server/agent-task-recovery-combo.test.tstests/codex-integration/combos.test.ts에 native disabled/쿨다운, 401 고갈, canonical vs noncanonical quota, eligibility/wait, 양쪽 site abort가 들어 있습니다. docs-site agents 설정 페이지 8개 로케일과 sub-agent guide도 “설정된 native”가 아니라 “고를 수 있는 native” 기준으로 맞춥니다. 호스트 CI(리눅스 4·macOS 2·gates)는 초록으로 보이지만, 베이스가 #3753이라 부모 머지 전에는 dev에 단독 착지하면 안 됩니다. 본문 체크리스트의 security 항목은 아직 비어 있고, 로컬 스위트/라이브 Kiro는 없습니다. types/config 대분할과 무관합니다. #3706은 이 캐리가 랜딩하면 close-don't-rebase leftover입니다.

우선순위 73인 이유다. opaque 다음 필수 칸이고 mixed combo의 “native 설정만으로 회복 봉인” 구멍을 막습니다. 다만 점수는 #3753보다 낮게 둡니다. 부모 draft/스택 의존, canonical quota 소유권 변경의 운영 체감, security 체크 미완이 남아서입니다. #3753 없이 올리면 깨집니다.

경로/심볼 - src/server/responses/core.ts recoverUnreadableEncryptedTask / 초기·failure 후 두 회복 사이트 / abort→cancel 유지
경로/심볼 - src/combos/resolve.ts targetProviderIsUsable + isCanonicalOpenAiForwardProvider quota 소유

경로/심볼 - 부모 #3753 / leftover #3706 / plan 050_combo_recovery.md
경로/심볼 - PR 본문 security checklist 미체크 · draft 게이트

메인테이너의 판단이 필요한 지점

  • #3753 Ready·머지 직후에만 이 PR을 Ready/머지할지(권장 순서)
  • canonical provider가 summary exhausted여도 account selector에 맡기는 정책이 2.44에 그대로 갈지
  • 본문 security 체크를 머지 전에 채울지(기존 http provider URL 정책 변경 없음이 전제)
  • 머지 후 #3706Landed via #3754로 닫을지

너의 추천
#3753을 먼저 머지한 뒤, 이 PR을 Ready로 바꾸고 exact-head CI 초록이면 머지하세요. #3706은 close-don't-rebase leftover로 랜딩 코멘트 후 닫으세요. 라이브 Kiro 금지. types/config 이슈 아님. Grok terminal(060)은 이 레이어 다음입니다.

surface guide and the referenced French, Simplified Chinese, and Traditional
Chinese agent configuration docs to scope it to cases where recovery is disabled
or fails, no routed target exists, or the ciphertext remains unreadable. Clarify
that recovery may dispatch to an available routed target when no
payload-eligible native target remains or eligible native targets are exhausted,
and keep the translations consistent with the English wording.

In `@src/server/responses/core.ts`:
- Line 2848: Update the recovery branch around recoveredTarget and
recoverUnreadableEncryptedTask so a failed late recovery returns the 400
unreadable_encrypted_agent_task response instead of falling through to
lastFailure, while preserving the 499 client-cancellation response. Call
adoptFailedChildLog(childLog) before returning the unreadable-task response. Add
a regression test covering native 401 followed by recovery 503, asserting no
routed request occurs and no recovered plaintext is persisted.

P2 Badge Avoid waiting on native cooldown before recovery

When an encrypted combo has an immediately available routed target and a canonical native target whose cooldown expires within waitForCooldownMs, this payload-filtered call waits for the native cooldown and then dispatches there, so recovery never runs. Normal combo waiting only occurs when every usable target is cooling, but the routed target is hidden here solely because it becomes readable after recovery; this can delay a task for up to ten minutes and contradicts the new cooling-target fallback behavior. Perform the native-preference check without waiting, then apply the configured wait while selecting the post-recovery target.

Comment on lines +172 to +176
Combo routing prefers a selectable canonical native ChatGPT target for encrypted tasks. If none
is usable, or native authorization attempts are exhausted, an explicitly enabled recovery may
make the task readable for one available routed target. All recovery trust and no-persistence
guards above still apply; a configured but disabled or cooling native target does not block this
fallback, and cancellation never becomes an unreadable-task error.

P2 Badge Reconcile the contradictory combo guidance

This new paragraph says an encrypted combo can recover and dispatch to a routed target, but the same section still tells users at lines 150–151 that combos consider only canonical native targets and return HTTP 400 if none is available, while the following recovery-options list also omits combo recovery. Update those earlier statements so the canonical English documentation presents one consistent behavior.
