fix(integrations): preserve TOML values by refusing lossy rewrites

[lidge-jun]

Summary

Managed client configuration rewrites can turn typed TOML dates and times into quoted strings during the JSON-cloned merge. Reject these documents through the shared parser before status or any writer admits the rewrite, while retaining support for quoted date strings.

Carries #3669 by @devswha, preserving the original authored commit and adding the client-integration architecture contract. Regressions cover nested temporal values and a real Kimi apply that must preserve file bytes, ownership records and journal state.

Verification

• git diff codex/d-roadmap-01a07265...HEAD --check passed.
• Independent plan/stale-source and implementation audits: PASS, no actionable blockers. The original production/test patch matches by stable patch ID.
• Exact-head documentation build on an isolated Mac mini checkout passed: 425 pages, head fdcdf0857eb1a3c52bb82557d77d2b930c61cb43.
• Current-head Cross-platform CI 33980488927 has passed Linux tests and common gates; remaining macOS/policy jobs are pending. Head: e0b5f74b4db8551cf200aca4a9c05b2750375d48.
• On that exact head, isolated macmini-cf validation with project Bun 1.4.0 and Node 22.22.0 passed bun run typecheck and the complete bun run test command (exit 0, no failed tests). An earlier run used the wrong global Bun/absent Node and is excluded from readiness proof.
• No local application tests or typecheck were run, as explicitly required by the owner. Hosted Cross-platform CI will supply current-head typecheck, platform tests and privacy checks. Documentation build is checked in an isolated remote checkout.

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

  • TOML configurations containing unquoted dates or times are now rejected as unsafe rather than rewritten incorrectly.
  • This protection applies to values in nested objects, arrays, and inline tables.
  • Unsafe configurations remain unchanged, with no partial updates recorded.
  • Quoted date and time values continue to be supported.

• Documentation

  • Updated integration guidance in English, French, Turkish, and Traditional Chinese to explain TOML date/time handling and manual editing requirements.

📝 Walkthrough

Walkthrough

The TOML parser now rejects unquoted date and time values, including nested values, before integration mutation. Tests verify parse and apply behavior. English, French, Turkish, Traditional Chinese, and internal documentation describe the restriction.

Changes

TOML temporal value safety

Layer / File(s)	Summary
Reject temporal TOML values src/integrations/config-io.ts, tests/clients/integrations-state.test.ts	parseConfig walks parsed TOML values and returns PARSE_FAILED for non-plain objects. Tests cover dates and times at multiple nesting levels and confirm quoted values remain supported.
Preserve unsafe apply behavior tests/clients/integrations-writer.test.ts	The Kimi integration test verifies that a TOML date literal returns unsafe, preserves file bytes, and creates no journal or ownership record.
Document TOML temporal handling docs-site/src/content/docs/guides/integrations.md, docs-site/src/content/docs/fr/guides/integrations.md, docs-site/src/content/docs/tr/guides/integrations.md, docs-site/src/content/docs/zh-tw/guides/integrations.md, structure/09_client-integrations.md, devlog/_plan/260906_d_integrations_delivery/011_toml_refresh.md	The documentation describes rejected typed dates and times, nested values, supported quoted strings, manual editing, and the refresh plan.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to e0b5f

Managed TOML edits now safely reject unquoted date and time values, but some localized Codex integration guides may not explain this behavior. Users of those guides could be surprised when automatic configuration updates are refused.

리뷰 · 우선순위 66 / 80

이 PR은 관리형 클라이언트 설정(TOML)에 typed date/time이 있으면 JSON 클론 머지에서 문자열로 바뀌는 손실을, 파서 단계에서 거절하는 가드입니다. 지금 HEAD의 src/integrations/config-io.ts parseConfig TOML 분기는 inf/nan 가드 뒤 Bun.TOML.parse 결과를 그대로 반환합니다. Bun이 Temporal 비슷한 객체를 주면, 이후 JSON 클론이 toJSON으로 문자열을 만들고 status/writer가 그 손실 문서를 받아들입니다. 이 변경은 parse 직후 객체를 걸어, 배열·인라인 테이블 안의 non-plain 프로토타입도 PARSE_FAILED로 돌립니다. 따옴표 친 날짜 문자열은 그대로 허용합니다. Kimi apply 회귀는 파일 바이트·ownership·journal이 안 바뀌는지도 봅니다.

베이스가 dev가 아니라 codex/d-roadmap-01a07265(문서 PR #3681의 브랜치)입니다. D 레인 2층(TOML admission)이고, 부모 #3681이 아직 OPEN·ready 상태입니다. 원본 #3669 carry입니다. 코드 자체는 HEAD의 config-io.ts에 깔끔히 붙는 형태라, 부모 docs만 먼저 들어가도 구현 hunk는 거의 그대로입니다. 다만 스택 규칙상 foundation 없이 이 PR만 dev에 직접 넣는 것은 베이스 불일치입니다. types/config 분할과 무관합니다.

클라이언트 통합 writer는 사용자 디스크의 IDE/에이전트 설정을 만집니다. 날짜 타입이 문자열로 바뀌면 “한 번 apply 했는데 expires가 깨졌다” 같은 조용한 손상이 납니다. refuse-before-admit 전략은 기존 inf/nan·JSON 숫자 가드와 같은 철학이라 config-io.ts에 자연스럽게 앉습니다. D 레인 foundation(#3681)만 순서를 지키면 됩니다.

라인 src/integrations/config-io.ts ~165 - HEAD는 아직 bare return Bun.TOML.parse(text)입니다. Temporal walk 가드가 없습니다.

경로 테스트 nested date/time × quoted string - 리터럴 날짜는 실패, 따옴표 문자열은 성공. 계약이 테스트에 잠겨 있습니다.

경로 integrations-writer Kimi - unsafe 판정·apply 거부·원문 보존·operation/record 없음. 실제 클라이언트 경로까지 이어집니다.

경로 structure/09_client-integrations.md - status와 mutation이 같은 classifier를 써야 한다는 기존 원칙 위에 temporal 거절을 명시합니다.

경로 베이스 #3681 - 아직 dev에 없음. 이 PR만 리뷰할 때는 구현 diff만 보면 되고, 머지 순서는 foundation → 이 레이어입니다.

경로 원본 #3669 - OPEN. 본문도 이 구현이 dev에 증명된 뒤 닫으라고 적었습니다.

메인테이너의 판단이 필요한 지점

• #3681을 먼저 머지한 뒤 이 PR을 retarget/dev rebase할지
• Temporal 거절을 “파일 전체를 unsafe”로 둘지, 나중에 date를 문자열로 정규화하는 옵션을 줄지(현재는 refuse)
• 체크리스트의 security 미체크를 머지 전 필수 독립 보안 리뷰로 볼지

너의 추천
구현은 좋고 범위도 맞습니다. #3681 머지(또는 이 브랜치를 최신 dev에 리베이스) 후 current-head CI 초록이면 머지하세요. 그다음 #3669를 landed로 닫고 D 레인의 다음 층으로 가면 됩니다. security 체크는 머지 전에 한 번 확인하세요.
