Summary

Optional voice sideband diagnostics now store only timestamp, direction, frame kind, byte count and the replacement-character flag. Damaged transcripts and binary frame excerpts no longer enter the diagnostic file. Original frames are still delivered unchanged.

Regression coverage verifies the exact metadata schema, damaged-text delivery, binary buffers and bounded views, malformed UTF-8, disabled logging and filesystem failure. The transport reference documents the limits.

Manual stack: this runtime layer targets dev; #3969 adds the client/proxy ownership documentation. Merge bottom-up.

Verification

  • Final cumulative head: 16ddf43c92f7cfa164a6bcb0d80101abc9450b81, based on dev at 900567af3f38ad6e07e4723c2eedeeffb95c57ab.
  • Cross-platform CI 34174322981: 26/26 jobs passed (workflow_dispatch, lane=all). Includes Linux, macOS, Windows, unsharded macOS control, typecheck, privacy, keyring and smoke checks.
  • The two voice regressions actually ran and passed in Linux job 101900745120.
  • Independent plan and final implementation/security reviews: PASS, no blockers. git diff --check: PASS. Authored voice code/tests/docs are unchanged across the fresh-dev integration.
  • Local product tests, typecheck, build, installation and red/green mutation: NOT RUN, as explicitly instructed. Only the final cumulative candidate supplies full runtime evidence; cancelled duplicate PR runs are not passing evidence.
  • Live audio latency: NOT MEASURED. No speed improvement is claimed.

Maintainer integration decision: acting as lidge-jun under the dev-only policy in MAINTAINERS.md, integrate without a second maintainer approval using the cumulative exact-head CI and independent security review above. No self-approval is asserted; outstanding maintainer objections were checked separately. This PR head is da0beec529d563fda6a6b6d4dd51d95e9b8782b7 and is an ancestor of the verified cumulative head.

Review disposition: CodeRabbit comment 3953190734 is not adopted. scripts/privacy-scan.ts:146-151 explicitly permits the maintainer's own local path in devlog evidence for reproducibility; other users' paths remain rejected. The note contains no credentials, the privacy gate passed, and the thread is resolved.

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.

Landing verified: #3968 merged as ac84ab2c5cf767d1ca7cd5612cdc80348b1e6139; #3969 merged as 9e1468d4b7a41b498ed2aca98507ada2c741afea. Fetched dev contains the tested cumulative head, and both trees are exactly 68b6eb5a5644b19e321be916de8b4d6429174648. The only merge-generated duplicate product CI (parent push run 34176133959) was cancelled; it is not verification evidence.

📝 Walkthrough

Walkthrough

The PR adds a scoped voice relay plan and pinned source notes. It changes live sideband diagnostics to record only metadata and a boolean U+FFFD indicator. Tests verify delivery, payload omission, input variants, disabled logging, and invalid-path handling.

Changes

Voice relay diagnostics

Layer / File(s) Summary
Relay plan and source baseline
devlog/_plan/260908_voice_relay/*
The plan defines three work phases, remote-only verification boundaries, ownership, and merge steps. The source note pins the upstream baseline and records existing implementation reuse and evidence limits.
Metadata-only frame logging
src/server/live.ts, structure/04-transports-and-sidecars.md, tests/server/server-live.test.ts
Live frame logs replace payload excerpts with a boolean fffd field. Documentation defines the metadata-only JSONL contract. Tests verify frame delivery, supported binary views, payload omission, disabled logging, and invalid-path handling.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to da0be

This change makes live diagnostics metadata-only and preserves frame delivery, but a committed planning source note still exposes a developer-specific absolute filesystem path. Remove or redact that path before merge.

이 PR은 Voice sideband의 선택 진단 로그(OCX_LIVE_FRAME_LOG)에서 프레임 내용(손상 구간 excerpt 포함)을 아예 빼는 보안·프라이버시 수정이다. 지금 dev HEAD(bbea77a48, #3966 provider namespace ownership)에는 src/server/live.tslogLiveSidebandFrame이 U+FFFD가 있으면 앞뒤 24글자 context를 JSONL에 남긴다. 그 설계 의도는 multibyte transcript 깨짐을 upstream/relay/client 중 어디에 둘지 단서로 쓰는 것이었지만, 짧은 손상 transcript나 바이너리 decode 조각이 디스크에 남는다는 뜻이다. 이 PR은 fffdContextLIVE_FRAME_LOG_CONTEXT_CHARS를 제거하고 기록 필드를 ts / dir / kind / bytes / fffd만 남긴다. 프레임 전달·계정 라우팅·릴레이 동작은 그대로다.

왜 지금 dev 기준으로 의미 있는가. Voice live 경로는 이미 src/server/live.ts + src/server/index.ts에 call-create·sideband·큐 바운드가 있고, tests/server/server-live.test.ts가 전달을 검증한다. 문제는 “전달은 맞는데 진단 파일이 민감 조각을 남긴다”는 축이다. 로그를 켠 운영자·지원 세션·디스크 스냅샷에 음성/텍스트 조각이 남는 비용을, attribution 편의보다 크게 본 선택이다. 문서(structure/04_transports-and-sidecars.md)도 같은 스키마 한계를 명시하고, 바이너리에서 UTF-8 decode 자체가 U+FFFD를 만들 수 있어 fffd 플래그만으로 peer를 지목하면 안 된다고 못 박는다. 계획 문서(devlog/_plan/260908_voice_relay/)는 upstream Codex 핀과 OpenCodex 소유 경계를 정리한 보조 자료다.

테스트 쪽은 기존 “context 포함” 기대값을 “정확한 키만 + 손상/정상 텍스트가 파일에 없어야 함”으로 바꾸고, text/ArrayBuffer/Buffer/offset view/malformed UTF-8/로깅 off/파일시스템 실패까지 단위로 덮는다. 전달 자체는 received에 손상 문자열이 도착하는지도 본다. 로컬 product 테스트는 메인테이너 지시로 NOT RUN이고, 최종 증거는 누적 헤드(codex/voice-contract-0908 / #3969)에서 Cross-platform CI만 치겠다는 스택 규칙이다 본문에 적혀 있다. 형제 PR #3969는 이 브랜치를 base로 한 docs 레이어다.

라인 91~93 - 주석이 “privacy: no frame content”로 바뀌는데, 바이너리 경로는 여전히 TextDecoder().decode(...)로 전체 view를 읽어 fffd만 본다. 디스크에는 안 남지만, 로그 경로가 켜진 매 프레임마다 decode 비용이 생긴다. 지금은 진단 전용이라 허용 가능하지만, 고빈도 sideband에서 부담이 보이면 샘플링·길이 상한을 따로 논의할 여지는 있다.
라인 117 근처 - fffd만 남기면서 attribution용 context가 사라진다. 예전 24글자 excerpt는 의도적 forensic 도구였다. 프라이버시를 택한 대가로 “어디에 깨졌는지” 단서가 약해진다. 문서가 그 한계를 말해 주지만, 지원 플레이북에 “이제 excerpt 없음”을 한 줄 더 박아 두는 편이 안전하다.
tests/server/server-live.test.ts 새 케이스 - env 복원이 previousFrameLog로 깔끔해졌고, unknown object는 기록하지 않는 기존 early-return도 검증한다. 좋은 방향이다.
devlog/_plan/260908_voice_relay/* - 공개 계획만 들어가고 상세 감사 메모는 .tmp에 둔다고 명시했다. 공개 트리 오염은 없다.
CI 운영 - task PR product run을 취소하고 누적 헤드만 본다는 운영 선택은 본문에 분명히 적혀 있다. 다만 리뷰어는 “이 PR 단독 초록불”을 통과 증거로 읽으면 안 된다.

메인테이너의 판단이 필요한 지점

  • attribution용 short context를 영구 포기할지, 아니면 redact/해시/길이 0 기본 + 별도 opt-in(OCX_LIVE_FRAME_LOG_CONTEXT=1)으로 둘지
  • #3968만 먼저 dev에 올릴지, #3969와 한 스택으로 누적 CI 통과 후 연속 merge할지 (본문은 bottom-up + 누적 헤드 CI를 요청)
  • 로컬 테스트 NOT RUN 정책을 이 스택에 계속 적용할지, merge 전 최소 server-live 한 번이라도 돌릴지

너의 추천
프라이버시 방향은 맞고 범위도 작다. #3969와 수동 스택이니 bottom-up으로 #3968을 먼저 머지할 준비로 두고, 누적 헤드(704839d044…) Cross-platform CI(lane=all)가 초록이면 이어서 #3969를 올린다. attribution이 아쉬우면 follow-up으로 opt-in context를 열되 기본은 지금처럼 metadata-only를 유지하자. labels는 건드리지 않았다.
