Summary

  • persist Remote Workspace device revocation before publishing the in-memory removal or closing its connection, so failed saves remain truthful and retryable
  • route every provider PATCH variant through one synchronous snapshot/mutate/save/rollback boundary
  • restore the existing plain config graph and descriptors in place after persistence failure, including nested persistence rebases and deletion provenance
  • keep reconciliation, cache invalidation, quota/thread cleanup, and catalog convergence after successful persistence only
  • document the two durability decisions in ADR-0103 and ADR-0104

Verification

  • Remote Workspace hub, provider atomicity, and test-layout suites: 36 passed, 0 failed, 1,794 assertions
  • privacy scan: passed
  • checks ran one at a time in disposable homes with CPUQuota at 75% or lower, MemoryMax at 1536 MiB or lower, no swap, low I/O weight, and bounded task counts
  • local typecheck/full-suite were not repeated under the conservative host ceiling; exact-head CI remains required

Security and compatibility

  • this touches device-token revocation semantics and therefore requires explicit security review
  • no token values, account identifiers, or request bodies are logged or added to fixtures
  • failed revocation deliberately leaves both durable authorization and the existing connection active; successful retry removes authorization before disconnecting
  • no Go counterpart was identified for these TypeScript management/Remote Workspace paths; reviewer confirmation is requested before merge

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

    • Provider updates now roll back cleanly when saving fails before publication, preserving the current configuration and routing state. Errors after changes have been published are still reported without reverting the live configuration.
    • Device revocation keeps enrollment and connections unchanged when saving fails. Successful revocations persist across reloads, and unknown or already-revoked devices do not trigger a write.
  • Documentation

    • Added guidance on durable provider updates and device revocation, including failure and retry behavior, and clarified pairing-grant behavior for disallowed origins and throttled sources.

@lidge-jun please prioritize both correctness and explicit security review: this PR changes device-token revocation ordering and provider persistence rollback. @Wibias GitHub currently rejects a formal reviewer request for your account, so please review via this mention. Focused failure/retry/reload/concurrency tests are green under the documented host limits. @codex security review

📝 Walkthrough

Walkthrough

Provider PATCH routes now use a transaction helper that restores captured configuration state after eligible failures. Persistence distinguishes failures before and after publication. Device revocation saves enrollment changes before updating Hub state or closing the connection. Tests cover failure and retry behavior.

Changes

Provider PATCH atomicity

Layer / File(s) Summary
Publication-aware persistence
src/config/atomic-write.ts, src/config/persist-unlocked.ts, src/config/live-reconcile.ts, structure/decisions/ADR-0120-provider-patch-publication-boundary.md, structure/config.md
Atomic writes report the rename point through afterRename. Persistence and live reconciliation mark post-publication errors with ConfigWritePublishedError; identical-byte saves are treated as published.
Transactional provider PATCH updates
src/server/management/provider-patch-transaction.ts, src/server/management/provider-routes.ts, tests/server/management-provider-atomicity.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json, structure/decisions/ADR-0104-durable-provider-patch.md, structure/gui-and-management-api.md
The routes use commitProviderPatch for account-mode, default-provider, and general provider updates. The helper snapshots plain objects and arrays while preserving identities and descriptors. It restores captured state for mutation and pre-publication save failures, but not for ConfigWritePublishedError. Tests cover rollback, retries, post-publication errors, and concurrent field-mask replay.

Durable device revocation

Layer / File(s) Summary
Save-before-close revocation
src/remote-control/workspace-hub.ts, tests/clients/remote-workspace-hub.test.ts, structure/decisions/ADR-0103-durable-device-revocation.md, structure/remote-workspace.md
revokeDevice saves filtered enrollment state before publishing it or closing the connection. Tests check that a failed save leaves device state and the connection unchanged, and that a successful retry persists across reloads.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 7d33b

A config write that succeeds before later work fails can leave provider routing stale or allow a later writer to use an outdated generation. Resolve these failure paths before merging unless that risk is explicitly accepted.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 7d33b

The new ordering reduces the risk of reporting a device as revoked before its removal is saved. A failure after a provider update has reached disk can still leave dependent runtime state awaiting cleanup, so the recovery behavior merits review.

Retained concerns

  • Medium · reliability · inferred: If provider bytes are published but a later registry refresh fails, the PATCH transaction preserves the published live change and throws before route-level reconciliation and cache cleanup. Dependent runtime state may therefore lag the persisted provider configuration until recovery.
Security review details

Security Blast Radius

  • inferred — The directly affected authorization scope is an enrolled Remote Workspace device and its connection; provider publication also affects runtime components that consume provider configuration. No new externally callable route or write-target selection authority was established by the inspected changes.

Trust Boundaries and Controls

  • observed — Revocation is session-gated and successful removal precedes disconnection. The atomic writer checks its resolved target before writing or calling the new publication hook.

Resilience and Maintainability Implications

  • inferred — Publication-aware handling is specific to the provider transaction. Other callers that adopt live configuration only after a persisted-mutation outcome can remain stale if persistence publishes and then throws; whether that condition's exposure changed in this PR is unestablished.

Hardening Proposals

  • proposed — Define recovery after publication separately from rollback: reconcile provider dependents after a published-error response, and establish whether hub stores must report a write that published before throwing so revocation can converge live authorization safely.

리뷰 · 우선순위 60 / 80

이 PR은 관리 화면에서 설정을 고칠 때, 파일 저장이 끝난 뒤에만 메모리와 연결을 바꿉니다. 원격 워크스페이스에서 기기를 취소하면 등록 명단을 파일에 먼저 저장하고, 그다음 메모리에서 빼고 연결을 끊습니다. 저장이 실패하면 기기는 그대로 남아 있고 토큰도 계속 통합니다. 같은 요청으로 다시 시도할 수 있습니다. 모르는 기기나 이미 취소된 기기는 파일을 다시 쓰지 않습니다. 프로바이더 PATCH도 저장이 성공한 뒤에만 라우팅 정리, 캐시 삭제, 카탈로그 맞추기를 합니다. 저장이 실패하면 바꾸기 전 설정 객체와 속성 설명을 제자리에 되돌립니다. 이 두 가지 결정은 ADR-0103과 ADR-0104에 적혀 있습니다. 베이스 브랜치는 dev입니다.

src/server/management/provider-patch-transaction.ts commitProviderPatch - 설정 파일을 디스크에 쓴 뒤의 뒷정리가 실패하면, 메모리 속 설정이 예전 값으로 돌아갑니다. src/config/persist-unlocked.ts 88행에서 config.json을 바꾼 다음 가격표와 모델 목록을 다시 만들고, src/config/live-reconcile.ts 513행에서 설정 버전 번호를 올립니다. 그 뒷정리가 예외를 던지면 디스크는 새 설정이고, 켜져 있는 서버의 라우팅은 옛 설정입니다. 서버를 다시 띄우거나 같은 변경을 다시 저장하기 전까지 둘이 다릅니다.

src/server/management/provider-patch-transaction.ts captureConfigGraphRollback - 저장 도중에 지워진 키를 되돌릴 때 Object.defineProperties가 그 키를 객체 맨 뒤에 붙입니다. 프로바이더 이름 순서는 DELETE가 다음 기본 프로바이더를 고를 때 씁니다. 실패한 저장 한 번이 그 순서를 바꿀 수 있습니다.

메인테이너의 판단이 필요한 지점

파일 쓰기가 끝난 뒤의 예외를 저장 실패로 볼지 정해야 합니다. ADR-0104는 저장 이후 효과는 이 함수의 트랜잭션이 아니라고 적었는데, 버전 번호와 가격표 갱신은 save() 안에서 파일 쓰기 다음에 실행됩니다. PATCH만 commitProviderPatch를 탑니다. POST로 프로바이더를 통째로 덮어쓰는 경로와 DELETE는 아직 밖입니다. POST는 핀을 건드렸을 때만 일부를 되돌립니다. 기기 취소는 저장 뒤에 close()가 예외를 던지면, 등록은 이미 사라져서 다시 호출해도 false만 반환하고 소켓을 다시 끊지 않습니다. Go에 같은 경로가 없다는 확인은 이 PR 본문이 요청한 그대로입니다.

너의 추천

파일 쓰기 전에 난 실패만 메모리에서 되돌리세요. 파일이 바뀐 뒤에 난 예외는 메모리 롤백에서 빼세요. 키를 복구할 때는 스냅샷에 있던 순서로 객체를 다시 만든 다음 속성 설명을 붙이세요. POST와 DELETE를 같은 경계에 넣을지는 이번 PR 설명에 한 줄로 범위를 적으면 됩니다. 기기 취소는 지금 순서(저장, 메모리 반영, 연결 종료)를 유지하세요. 저장이 실패하면 토큰과 연결을 둘 다 살려 두는 쪽이 맞습니다.

Maintainer security sign-off (owner) for head 7d33b4577d, release round 2.66.0.

Independent security review (Kimi kimi-for-coding-highspeed, two rounds, 2026-09-25): PASS. The two earlier required fixes are implemented and tested in tests/server/management-provider-atomicity.test.ts: live config is no longer rolled back after config.json is atomically published, and rollback restores provider key order. The two newer CodeRabbit threads (generation bump and follow-up cleanup after a post-publication failure) describe gaps dev already has on the same path; they were answered and resolved as follow-ups. Route authentication is unchanged; no token or secret logging was introduced.

Exact-head CI: Cross-platform CI passed on this head after dev was merged in; local union with #5839 and #5757 on current dev: typecheck, the PRs' tests, structure and privacy checks pass.
