Summary

  • Preserve redacted-before-signed ordering for legacy combined reasoning envelopes in Anthropic streaming output, matching JSON even after preceding deltas. Thinking is item-bound and deferred until closure; text/tool arguments remain incremental.
  • Preserve A's shared translator-budget admission in all five encode/decode plumbing sites. Positive fallback fixture limits reflect the real allocation peak; production limits and original 70 KiB overflow assertions are unchanged.
  • Refs Bug: preserve Anthropic thinking replay through proxy-auth translation and clarify prompt-cache behavior #3719. Outbound ordering is the only resolved slice; multi-turn replay/cache acceptance stays open.

Verification

  • Local test suites, typecheck, build and install: NOT RUN, explicitly prohibited by the maintainer.
  • Exact top head: fe9460372597061f572beee6c325009fef618c42. Cross-platform CI run 34120761219. PASS under the explicit per-chain acceptance policy: all 16 required jobs completed successfully: Linux 4, macOS 2, gates, API usage, storage, all keyring/npm jobs, and Docker. Excluded Windows shards/macOS control are still running and are not part of this verdict.
  • Remote gates: GUI 1787 pass / 0 fail; lint 0 errors / 0 warnings; TypeScript, privacy scan and GUI build passed.
  • Independent review: Astra-high Dirac: PASS, blockers=0, including A/D composition at a9f1d0ffe75957b592c4670b5b2e890912488506. Reviewed ordering/identity, budget admission, genuine signatures, hidden-text handling and cancellation. Current outbound/test files preserve that reviewed composition.
  • Later explicit user policy: Windows 6 shards and macOS control are excluded from per-chain acceptance and reserved for one final release-train-head verification. Their state is not represented as passing evidence for this chain.

Ordinary dependent PRs only; native stack membership checked separately, no native registration. Main task alone performs maintainer integration under MAINTAINERS.md; this is not self-approval. Before integration, refresh dev and prove expected cumulative tree equals the tested top tree. No merge performed by this lane.

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

    • Improved streaming of reasoning content so redacted blocks appear in the correct order.
    • Prevented reasoning text from being incorrectly combined across separate items.
    • Preserved signatures, text/tool ordering, cancellation handling, and budget limits during streaming.
  • Tests

    • Expanded coverage for reasoning boundaries, delayed closures, malformed identities, signing, cancellation, and JSON/SSE output consistency.

Maintainer integration decision (MAINTAINERS.md, dev-only admin integration): @lidge-jun integrates lane D's manual chain (#3877#3902#3903#3904#3905) into dev bottom-up. Chain-top evidence at head fe9460372: Cross-platform CI run 34120761219 — Linux test 1/4–4/4, macOS 1/2, 2/2, gates (GUI 1787/0, lint, typecheck, privacy, build), storage policy, api usage, keyring ×3, npm-global ×3, docker smoke = success; Windows shards and macos control deferred to the final release-train head by maintainer policy. Prospective merge tree of origin/dev@f4a4b468f + top = ded24302f = tested tree. Independent per-layer reviews PASS; screenshots from this run's dashboard-preview artifact. Local suites NOT RUN. Maintainer integration, not self-approval.

Review Change Stack

📝 Walkthrough

Walkthrough

Lane D adds roadmap documentation for several planned features. The implemented Claude outbound change buffers thinking output, separates reasoning items, and emits redacted blocks before signed thinking content. Integration tests cover ordering, identity boundaries, budgets, cancellation, and completion.

Lane D planning documents

Layer / File(s) Summary
Roadmap scope and audit resolution
devlog/_plan/260907_lane_d/000_plan.md, devlog/_plan/260907_lane_d/001_roadmap_audit.md
The roadmap defines six implementation phases, evidence rules, branch handling, CI policy, and merge ownership. The audit records corrections and CI-based acceptance conditions.
Planned implementation slices

Planning documents specify deferred changes for reasoning output, receipt recovery, account price identity, manual price editing, and custom usage windows.

Deferred Claude thinking emission

Layer / File(s) Summary
Buffer and reasoning-item handling
src/claude/outbound.ts
Thinking deltas remain buffered until closure. Blocks track bounded reasoning item identities, close when the identity changes, and assign indexes at emission. Redacted blocks are emitted before signed thinking content.
Deferred thinking integration coverage
tests/claude-integration/claude-outbound.test.ts
Tests cover separate item identities, malformed identities, JSON/SSE parity, redacted and signed output, ordering, budget limits, cancellation, signatures, and terminal sequencing.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to c35b5

The implemented outbound ordering change has no supported blocker, but the custom-window roadmap should clarify end-to-end cache propagation before it guides implementation.

이 PR은 현재 dev(HEAD ece556a6e)의 Anthropic SSE 브리지에서 레거시 combined reasoning envelope의 블록 순서만 맞춥니다. 지금 devsrc/claude/outbound.ts JSON 경로(responsesJsonToAnthropicMessage)는 이미 redacted_thinking을 signed thinking보다 앞에 두지만, SSE 경로(responsesSseToAnthropicSse)는 reasoning delta가 오는 즉시 thinking 블록을 열어 버립니다. 그래서 같은 envelope라도 스트림을 모으면 JSON과 순서가 어긋날 수 있습니다. #3719 전체(멀티턴 replay·prompt-cache 재설계)가 아니라, 본문이 말하는 outbound 순서 슬라이스만 다룹니다.

핵심 동작은 thinking start/index/delta를 닫을 때까지 미루고, 같은 item의 output_item.done에서 redacted 블록을 먼저 낸 뒤 pending signed thinking을 flush하는 것입니다. reasoningItemKey로 item 경계를 나누어, 다른 item의 done이 앞선 thinking을 가로채 재배치하지 못하게 했습니다. text·tool 인자는 계속 증분 방출하고, 버퍼/시그니처/취소·오버플로 예산은 기존 한도를 유지합니다. 테스트는 JSON↔수집 SSE 리터럴 패리티, item 경계, near-limit, cancel, “thinking은 닫힐 때까지 기다리고 text/tool은 살아 있음”까지 덮습니다. lane D 계획 문서(devlog/_plan/260907_lane_d/*)도 같이 들어 있지만, 이 PR의 제품 코드 변경은 outbound + 테스트입니다. PR은 아직 draft입니다.

types/config 분할에 밟히는 파일이 아니라 close-don't-rebase 대상이 아닙니다. #3719는 열어 두는 것이 맞습니다.

라인 - src/claude/outbound.ts ensureBlock("thinking") / closeOpenBlock: thinking이 보이는 시점이 “닫힐 때”로 바뀝니다. 클라이언트가 토큰 단위 thinking 스트림을 기대하면 체감 지연이 납니다. 계획서도 인정한 트레이드오프이지만, 문서/가이드에 한 줄 적어 두면 이슈 재발이 줄어듭니다.

경로/심볼 - devlog/_plan/260907_lane_d/020_receipt.md ~ 050_usage_ranges.md: D2~D5 계획까지 이 D1 PR에 같이 들어 있습니다. 체인은 이해되지만, 리뷰 범위가 “순서 수정”보다 넓어 보입니다. 코드 머지 판단은 outbound diff만 기준으로 두면 됩니다.

경로/심볼 - #3719: 이 PR만으로 이슈를 닫으면 안 됩니다. inbound replay·cache 수락은 여전히 열려 있어야 합니다.

메인테이너의 판단이 필요한 지점

  • draft를 언제 ready로 올릴지(D1만 단독 머지 vs D2 베이스로만 쓸지)
  • thinking 비가시 지연을 제품 기본으로 받아들일지, 가이드에 명시만 할지
  • lane D 문서 묶음을 D1에 남길지, 문서-only 커밋으로 분리할지

너의 추천
코드 슬라이스는 dev 기준으로 타당합니다. #3719 재설계로 범위 키우지 마세요. D1을 머지할 거면 draft를 ready로 바꾸고, Cross-platform CI가 이 헤드에서 초록인 것을 확인한 뒤 머지하세요. 머지 후에도 #3719는 open 유지하고, 이 PR 본문처럼 “outbound ordering only”로 이슈에 남기세요. 중복·재베이스 강요 없이, 후속 D2는 이 커밋 위를 베이스로 이어가면 됩니다.

Defer item-bound thinking emission until its envelope can place redacted blocks first. Preserve budget enforcement and live text/tool output. Refs #3719; replay/cache acceptance remains open.
