Summary

  • Every persisted config mutation (management API, CLI, and internal writers) is now recorded in the existing config-mutation.sqlite coordinator, atomically with the config write: who changed it (surface + route/command), which fields changed, and redacted before/after values.
  • saveConfig, saveConfigPreservingClaudeCode, and mutatePersistedConfig accept an optional ConfigMutationSource; management-API and CLI call sites pass their route/command (e.g. PUT /api/providers, ocx config set), internal writers are labeled internal.
  • GET /api/config/mutations?limit=N returns the trail newest-first (default 100, cap 1000) plus the retention bound; retention is bounded to the newest 5,000 rows, changed-field paths are capped, and redacted values are size-bounded.
  • Secrets (apiKey, tokens, headers, URL userinfo, credentials) are redacted with the existing redactSecrets machinery; byte-identical saves record nothing; crash recovery replays write-ahead markers transactionally.

📝 Walkthrough

Walkthrough

Configuration persistence now records source metadata, changed fields, and redacted before/after snapshots in SQLite. CLI, internal Codex, and management API mutations provide operation details. A management endpoint and tests cover retention, crash recovery, module boundaries, and authentication.

Changes

Configuration mutation auditing

Layer / File(s) Summary
Audit storage and persistence integration
src/config-mutation-audit.ts, src/config.ts, src/lib/redact.ts
Configuration saves record bounded, redacted mutation snapshots atomically. The implementation tracks changed fields, handles retention, reconciles pending writes after crashes, and distinguishes unchanged saves.
CLI and internal mutation sources
src/cli/*, src/codex/*
CLI commands and Codex internal operations pass surface and detail metadata to configuration persistence helpers.
Management API mutation sources
src/server/management/*, structure/05_gui-and-management-api.md
Management routes annotate configuration writes with API operation details. GET /api/config/mutations returns authenticated, bounded audit rows and retention metadata.
Audit behavior validation
tests/config-mutation-audit.test.ts, tests/config-mutation-audit-boundary.test.ts, tests/server-management-auth.test.ts, tests/cli-provider.test.ts, structure/02_config-and-codex-home.md
Tests and specifications cover snapshots, field tracking, secret redaction, no-op saves, retention, crash recovery, rollback behavior, module boundaries, API retrieval, and authentication.

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

Merge Risk: 🟡 Moderate · up to 21bbe

This PR adds persisted config mutation auditing, but current behavior can record incorrect before/after values, merge distinct fields, mislabel mutation sources, or lose audit history after a failed write. These concrete audit-data integrity issues should be fixed or explicitly accepted before merging.

Hi @Wibias / @lidge-jun — this PR needs a maintainer-sponsored label to pass the hygiene gate: the diff touches src/codex/auth-api.ts, src/oauth/login-cli.ts, and src/server/management/oauth-account-routes.ts only to attach a ConfigMutationSource label to already-existing save calls (no authentication or credential logic changes). Happy to adjust the touch surface if you'd prefer the labels dropped from those files instead. The rest of the PR records every persisted config mutation (surface/route, changed fields, redacted before/after) in the existing config-mutation sqlite and exposes GET /api/config/mutations.

리뷰 · 우선순위 48 / 80

설명: 이 PR은 config.json 을 누가, 어떤 경로로, 어떤 필드를 바꿨는지를 기존 config-mutation.sqlite 에 같이 남긴다. 지금 CURRENT dev HEAD는 ced9a85c5 이다. 이 시간에 착지한 것은 문서뿐이다: #2348 WP4, #2349 GO. 현재 HEAD src/config.ts 의 saveConfig / mutatePersistedConfig / saveConfigPreservingClaudeCode 는 바이트를 원자 기록하고 세대 번호를 올리지만, 누가 썼는지는 테이블에 없다. CONFIG_MUTATION_DB_FILENAME 은 이미 config-mutation.sqlite 다. 이 PR은 같은 트랜잭션 안에 config_mutation_audit 테이블을 만들고, surface(cli/api/internal) 와 경로/명령, 필드 목록, 레드액트된 before/after 를 넣는다. 바이트가 같으면 행을 안 남긴다. 보관은 최신 5000행, 필드 64개, 값 4KiB. GET /api/config/mutations 가 최신부터 돌려준다. 관리 API와 CLI 호출부는 경로/명령을 넘긴다. 내부 기록기는 internal 이다. 방향은 운영자가 GUI 수정과 백그라운드 마이그레이션을 구분하게 하려는 것이다. 다만 이 PR은 src/config.ts 를 크게 고친다. types.ts/config.ts 스플릿이 진행 중이면 무효화되기 쉽다. #2350#2355 도 같은 파일을 만진다. 드래프트다. 본문 체크리스트는 4칸이 채워져 있지만 GitHub 는 아직 draft 다. Cursor #2334 는 cursor-pool 모듈+테스트만. #2332 H2 는 discovery 전용. #2320 overflow + #2342 size prior 는 dev. 카탈로그 팁은 Ox Alpha x-preview-f-free + deepseek-v4-flash-vision-exp. package.json 2.27.0. #2188 사이드카는 이미 dev. 설정 감사는 유용하지만 릴리스 GO 직후 같은 파일 충돌 레인에 있어서 48.

src/config.ts recordConfigMutationInCurrentTransaction DELETE OFFSET - 행 제한 숫자를 SQL 문자열에 붙인다. 숫자 변수라도 바인드 플레이스홀더가 더 맞다
src/config.ts redact 임포트 - redactSecretString 과 redactSecrets 를 두 줄로 가져온다. 한 줄로 합친다
src/server/management/config-routes.ts GET /api/config/mutations - 관리 API 인증 뒤에 레드액트된 before/after 를 준다. 로컬 전용인지, 필드 이름에 apiKey 같은 키가 남는지를 보안 리뷰에서 본다
saveConfig / mutatePersistedConfig 시그니처에 ConfigMutationSource - 내부 writer 를 빼먹으면 감사 구멍이 생긴다. 호출부 누락이 없는지 테스트가 잠가야 한다
src/config.ts 대규모 수정 vs types.ts/config.ts 스플릿 - 스플릿이 먼저 착지하면 이 PR은 리베이스하지 말고 닫고 다시 연다

메인테이너의 판단이 필요한 지점

  • 감사 API를 루프백 로컬 관리 읽기 허용 목록에 넣을지, GUI 세션만 볼지
  • #2355 divergence 경고와 같은 설정 관측 레인으로 묶을지, 따로 둘지
  • 내부 자동 저장을 전부 internal 로 남기면 행이 빨리 찬다. 사람 손 경로만 남길지

너의 추천
드래프트를 유지한다. 게이트가 레디로 뒤집힌 뒤에만 본다. #2350 스키마 한 줄, #2355 SHA 경고와 한 커밋으로 섞지 않는다. config.ts 를 세 PR이 동시에 만지니 머지 순서를 정한다. SQL OFFSET 보간을 바인드로 바꾸고 redact 임포트를 한 줄로 만든다. types.ts/config.ts 스플릿이 saveConfig 를 이미 옮긴 뒤에야 충돌이 보이면 리베이스하지 말고 닫고 다시 연다. 지금은 그 정도 아님. 라벨은 그대로 둔다. 프리뷰 배포가 아니다.

Resolved the hygiene gate without maintainer sponsorship: dropped the ConfigMutationSource labels from the three auth-surface files (those writers now default to internal), bound the retention OFFSET as a SQL bind, and merged the redact imports into one line (b922ec0). Hygiene + enforce-target are green and the PR is ready for review.

3556-3572: 📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win

Same snapshot mismatch, duplicated across both branches. Extract one helper.

Lines 3562 and 3569 snapshot persistedConfig and projectedConfig respectively, not the object that persistConfigUnlocked serialized. The disk-only-provider mismatch described on Lines 3076-3079 applies to both branches.

The persist-bump-snapshot-record block now appears four times in this file (Lines 3076-3080, Lines 3167-3171, Lines 3560-3564, Lines 3567-3571). Four copies means the fix above must be applied identically four times, and a future change to the audit contract can drift between them. Extract one helper and call it from every persist path.

♻️ Proposed helper
+/** Persist under the open mutation transaction and record one audit row for a changed write. */
+function persistAndRecordConfigMutation(
+  candidate: OcxConfig,
+  beforeRaw: unknown,
+  source: ConfigMutationSource,
+): boolean {
+  const written = persistConfigUnlocked(candidate);
+  if (!written.changed) return false;
+  bumpGenerationForCooperatingConfigWrite();
+  const snapshot = buildConfigMutationSnapshot(beforeRaw, written.persisted);
+  recordConfigMutationInCurrentTransaction(source, snapshot.fields, snapshot.before, snapshot.after);
+  return true;
+}

Then both branches here collapse:

     if (persistedBinding) {
       const persistedConfig: OcxConfig = { ...projectedConfig, port: persistedBinding.port };
       if (persistedBinding.hostname === undefined) delete persistedConfig.hostname;
       else persistedConfig.hostname = persistedBinding.hostname;
-      if (persistConfigUnlocked(persistedConfig)) {
-        bumpGenerationForCooperatingConfigWrite();
-        const snapshot = buildConfigMutationSnapshot(onDisk, persistedConfig);
-        recordConfigMutationInCurrentTransaction(source, snapshot.fields, snapshot.before, snapshot.after);
-      }
+      persistAndRecordConfigMutation(persistedConfig, onDisk, source);
       persistedLiveServerBinding.set(config, persistedBinding);
     } else {
-      if (persistConfigUnlocked(projectedConfig)) {
-        bumpGenerationForCooperatingConfigWrite();
-        const snapshot = buildConfigMutationSnapshot(onDisk, projectedConfig);
-        recordConfigMutationInCurrentTransaction(source, snapshot.fields, snapshot.before, snapshot.after);
-      }
+      persistAndRecordConfigMutation(projectedConfig, onDisk, source);
     }

- Line 120: Update setIntegrationEnabled to accept an optional
ConfigMutationSource parameter defaulting to the current source, and use it when

than the pre-merge candidate. Apply this at src/config.ts lines 3067-3080 and

persist, generation-bump, snapshot, and recording logic into a shared helper.
- Around line 2931-2941: Update buildConfigMutationSnapshot to redact every path

secret-shaped keys are sanitized before fields is returned.
- Around line 2835-2843: Update readConfigMutationAudit so
configMutationDatabasePath is not used for read-only resolution, since it
creates and hardens the directory and can throw before the try block. Reuse or
add a side-effect-free path resolver for the audit database, keep path
resolution and database access within the method’s existing error-handling
contract, and ensure missing or inaccessible database/table state returns an
empty trail without creating or modifying directories.
- Around line 2874-2908: Update collectConfigDiffPaths and its callers to carry
the original path segments alongside the dotted display string, then pass those
segments to extractConfigValueAtPath instead of splitting the joined path on

metadata.
- Around line 85-95: Extend the configuration mutation audit tests with a
regression case for a provider added directly to config.json: import
readFileSync and writeFileSync, modify the on-disk providers before calling
saveConfig, then verify the audit does not report that provider as deleted and

Addressed all 13 CodeRabbit findings in c3450d5:

  1. ocx config set/unset now record distinct details via the action value.
  2. setIntegrationEnabled and the Codex/Grok/Claude wrappers accept a ConfigMutationSource; management routes and CLI entries now pass their route/command.
  3. readConfigMutationAudit resolves the database path with a side-effect-free helper (no mkdir/chmod/ACL) and returns an empty trail on any error.
  4. Diff paths now carry segment arrays, so dotted provider/model keys resolve their before/after values instead of nulling them.
  5. Every path segment is redacted before it is persisted and echoed by the API.
  6. persistConfigUnlocked returns the exact persisted document; snapshots (all three sites, collapsed into one helper) compare what was actually written, so disk-only providers are never reported as deleted.
  7. Agent-settings sources now identify the real mutation (POST /api/claude-desktop/apply, PUT /api/subagent-model-fallback); auto-apply fingerprints are recorded as internal.
  8. GET /api/config/mutations is gated to admin-token/gui-session principals (401 anonymous, 403 capability principals).
  9. apiKeyPool and oauthClientSecret join the sensitive-key matcher.
  10. Regression tests: secret-shaped provider names, dotted keys, credential leaves, disk-only preservation, typed retention assertions, anonymous/unauthorized route rejection, and a real-server 401/200 boundary test.

12 audit tests + 111 related tests pass; typecheck clean.

equivalent commit design. Ensure failures after the rename—including SQLite
insertion, retention pruning, commit, or process interruption—are detected and
repaired before subsequent reads or writes, including byte-identical retries, so
every persisted config change eventually has its audit record.

baseline from the exact persisted document in commitBase.raw, parsing those
bytes before calling persistConfigUnlocked. Replace the current
commitBase.diagnostics.config argument while preserving the existing projected
output and generation-bump behavior, so it matches saveConfig and
saveConfigPreservingClaudeCode.

verifies the marker remains; then perform a successful saveConfig and assert the
marker’s audit row is replayed. Update the transaction flow around
reconcilePendingConfigMutationAudit so marker deletion occurs only after COMMIT,
preserving the marker when the mutation rolls back.

3260-3278: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Do not overwrite a reconciled marker before its replay commits.

At Line 3272, a new save replaces the only pending marker even when Lines 2771-2773 have replayed an older marker in the current uncommitted transaction.

For example, a crash leaves config.json at C1 with marker P1. The next save inserts the P1 audit row, then overwrites P1 with P2 before writing C2. If the C2 write fails, the transaction rolls back the C1 audit row. The remaining P2 hash does not match C1, so later reconciliation drops it. The persisted C1 mutation then has no audit row.

Commit recovered markers in a separate reconciliation transaction before starting a new config mutation, or use a durable ordered marker journal. Add a regression test that forces a config write failure after reconciliation and verifies that the original marker still replays.

As per path instructions: “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

1237-1243: 🩺 Stability & Availability | 🔵 Trivial

Consider whether high-frequency internal routing writes should share the retention budget with human mutations.

Both call sites are correctly labeled surface: "internal", and both are guarded so no row is written for a no-op: Line 1240 returns early when the account is unchanged and no pin was released, and persistConfigUnlocked returns null for byte-identical saves without entering the audit path at all.

The remaining consideration is operational. Under quota pressure, setActiveCodexAccount and releaseDrainedCodexAccountPin can fire repeatedly with genuinely changed bytes. Each such write costs one marker file, one directory fsync, one row insert, and one retention DELETE. With CONFIG_AUDIT_MAX_ROWS = 5000 shared across all surfaces, sustained rotation churn can evict the api and cli rows an operator most wants during an incident review.

Two options worth weighing, neither blocking this PR:

  • Keep one table and expose a surface filter on GET /api/config/mutations, so an operator can read the human-attributable trail without paging through rotation noise. An index on (surface, id) would keep that query cheap.
  • Apply retention per surface, so internal churn cannot displace api and cli history.

An index on surface is worth adding regardless if a filter is planned, since the current read path only orders by id.

Also applies to: 1325-1335

Inline comments:
In `@src/config-mutation-audit.ts`:
- Around line 462-476: Update boundAuditValue and the redactApiKeyEntries call
chain to pass the known apiKeys-subtree context when key is "apiKeys", ensuring
degraded entries without id, name, or createdAt still redact their key field.
Add a regression test for an entry shaped as [{ key: "<secret>" }] that verifies
the secret is absent from both the persisted audit row and the management
endpoint response.
- Around line 165-172: Make deduplication race-free in
ensureConfigMutationAuditTable by enforcing uniqueness on mutation_id, including
an idempotent unique index for existing databases. Update the INSERT in the
config mutation audit write path to use INSERT OR IGNORE while retaining the
existing SELECT fast path, so concurrent reconciliation cannot create duplicates
or raise constraint errors.

In `@src/config.ts`:
- Around line 2418-2432: Make marker-file deletion best-effort at both affected
sites in src/config.ts:2418-2432 and src/config.ts:2450-2458 by catching and
ignoring unlink errors from deletePendingConfigMutationAuditAtPath and
deletePendingConfigMutationAudit after the transaction commits. Preserve
successful persisted writes and add a regression test that forces an EPERM
unlink failure and verifies the surrounding save still succeeds.
- Around line 2630-2643: Add a one-shot post-rename failure seam in the save
flow after atomicWriteFile succeeds and before the enclosing transaction
commits, while preserving production behavior. Clear this seam alongside
failConfigAtomicWriteForTests in the config-mutation-audit test cleanup. Add
regression coverage asserting the save throws with new config bytes persisted,
no audit row yet, the marker remains, and the next saveConfig causes
reconcilePendingConfigMutationAudit to replay exactly one row for the same
mutation ID.

In `@structure/05_gui-and-management-api.md`:
- Around line 107-108: Remove the blank line immediately before the “Config
mutation audit” row so it remains contiguous with the existing API ownership
table and all subsequent rows render as table rows.

In `@tests/config-mutation-audit-boundary.test.ts`:
- Around line 22-28: Update the custom failure message in the import-validation
loop to interpolate the actual spec value by removing the escape before the
template expression. Keep the existing two-argument expect call and allow-list
logic unchanged.

In `@tests/config-mutation-audit.test.ts`:
- Around line 658-673: Add a deterministic recovery test seam around
readConfigMutationAudit so newer-marker is written after recovery snapshots
marker paths but before stale-marker cleanup, then assert it remains present.
Ensure the seam exercises the cleanup window in src/config-mutation-audit.ts
rather than creating the marker only after recovery completes; do not use a
second recovery pass.
