Summary

  • Persist OAuth-provider startup reconciliation through the shared locked mutation path before adopting changes into the live config.
  • Rebase reconciliation on the freshest persisted config so concurrent provider edits survive startup.
  • Apply the same persist-before-adopt ordering to model-rename startup migration.
  • Fail closed when persisted state is missing, invalid, or cannot be committed, preventing a later startup save from writing stale live state.
  • Preserve live object identity and adopt only reconciliation-owned provider/version fields.
  • Emit safety warnings even when a model-rename projection correctly makes no mutation.

This is an internal startup consistency fix. It does not change the config schema, credential format, or user-facing commands, so no docs or release-note update is needed.

Security review: two independent reviews checked persistence ordering, unavailable-state handling, concurrent edit preservation, object identity, and secret exposure. Their original findings (silent continuation after unavailable persistence and no-op identity replacement) are fixed. A later CodeRabbit warning-emission finding was also fixed. No credentials or request data are logged or serialized by this change.

Verification

  • bun test tests/providers/model-rename-migration.test.ts tests/oauth/oauth-provider-reconcile.test.ts tests/test-layout.test.ts — 26 pass, 0 fail on the current head
  • bun run typecheck — pass on the current head
  • bun run privacy:scan — pass on the current head
  • git diff --check — pass on the current head
  • bun run test — 17,970 pass, 14 skip, 0 fail before upstream-only test relocations and the warning-only follow-up; relocated focused suites and the layout guard pass on the current head
  • Independent security/concurrency review — clean after fixes
  • Independent correctness/maintainability review — clean after fixes

📝 Walkthrough

Walkthrough

OAuth reconciliation and model-rename startup migration now use cloned projections. Persistent paths rebase changes on the latest stored configuration, while successful results update the live configuration in place.

Changes

Configuration persistence flows

Layer / File(s) Summary
OAuth reconciliation persistence
src/oauth/index.ts, tests/oauth/oauth-provider-reconcile.test.ts
reconcileOAuthProviders tracks touched providers and catalog versions. Persistent reconciliation mutates the latest stored configuration and merges committed keys into the live config. Non-persistent reconciliation updates the supplied config directly. Tests cover unavailable persistence, concurrent edits, stale live state, and the explicit non-persistent path.
Model-rename startup migration
src/providers/model-rename-startup.ts, tests/providers/model-rename-migration.test.ts
The migration projects a cloned config, preserves the original object on no-op results, supports an optional save callback, and otherwise uses mutatePersistedConfig. It adopts committed data in place and throws when persistence is unavailable. Tests cover identity preservation, warnings, and persistence failure.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to cf0b3

OAuth reconciliation and startup model-rename migration now persist projected configuration changes before adopting them in memory, avoiding stale-state overwrites while preserving expected warnings and failure behavior. No current merge-blocking risk remains.

설명

이 PR은 서버가 켜질 때 OAuth 프로바이더 설정을 고치는 순서를 바꿉니다. 지금 dev HEAD(5424ad465, #3511 레이아웃 슬라이스까지)의 src/oauth/index.ts reconcileOAuthProviders는 메모리에 있는 config를 직접 고친 다음, 바뀌었으면 saveConfig(config)로 디스크에 씁니다. src/providers/model-rename-startup.tsrunModelRenameStartupMigration도 같은 패턴입니다. 디스크에 이미 다른 운영자 편집이 있어도, 시작 시점의 옛 메모리 스냅샷이 그 위를 덮어쓸 수 있습니다. 반대로 디스크에 쓸 수 없는데도 메모리만 고치면, 나중에 다른 저장이 그 불완전한 상태를 굳힐 수 있습니다.

이 브랜치는 고칠 내용을 먼저 projectOAuthProviderReconciliation으로 복사본에 그려 보고, 실제로 쓸 때는 이미 dev에 있는 mutatePersistedConfig(src/config.ts)로 가장 최신 디스크 설정을 다시 읽어 같은 투영을 적용한 뒤 커밋합니다. 그다음에야 메모리 config에 투영이 만진 프로바이더/Antigravity 버전 필드만 adoptOAuthReconciliation으로 옮깁니다. 모델 이름 이전(runModelRenameStartupMigration)도 같은 “디스크에 먼저, 메모리 채택은 나중” 순서로 맞춥니다. 디스크가 없거나 깨졌거나 충돌이면 예외로 막고, 메모리 입력은 그대로 둡니다. 스키마·자격증명 형식·사용자 명령은 안 바꿉니다.

테스트도 방향을 잘 잡고 있습니다. 동시 편집이 note 같은 비조정 필드를 남기는지, 디스크가 이미 맞춰져 있으면 오래된 메모리만 맞추는지, 저장 불가면 메모리가 안 바뀌는지, no-op이 객체 정체성을 지키는지까지 tests/oauth-provider-reconcile.test.tstests/model-rename-migration.test.ts에 있습니다. 작성자 말대로 로컬에서 관련 테스트·typecheck·privacy·전체 스위트가 통과했다고 하니 내용 자체는 랜딩 후보에 가깝습니다.

다만 지금 GitHub 상태는 바로 머지할 수 없습니다. draft이고, intake: hygiene-blocked(unsponsored_surface: src/oauth/index.ts)라서 maintainer-sponsored가 필요합니다. 더 크게는 #3511이 tests/oauth-provider-reconcile.test.tstests/oauth/oauth-provider-reconcile.test.ts로 옮긴 뒤라, 이 PR은 옛 루트 경로를 패치해서 CONFLICTING/DIRTY입니다. src/oauth/index.tssrc/providers/model-rename-startup.ts는 합쳐질 수 있어도, OAuth 테스트 쪽은 경로를 새 위치로 옮긴 리베이스가 필수입니다. 옛 경로에 파일을 다시 만들면 레이아웃 열차와 어긋난 유령이 생깁니다.

점수 64는 시작 시 설정 일관성·동시 편집 보존이 실제 운영 버그 축이라서입니다. types/config 분할 캠페인과 겹치지는 않습니다. 리베이스와 스폰서십만 끝나면 좁은 내부 픽스로 올리면 됩니다.

라인 - tests/oauth-provider-reconcile.test.ts 전체 - #3511 이후 실제 파일은 tests/oauth/oauth-provider-reconcile.test.ts 입니다. 이 패치를 옛 루트 경로에 두면 충돌이거나 루트에 유령 테스트가 생깁니다.
src/providers/model-rename-startup.ts - 예전에는 projection.warnings를 changed 여부와 관계없이 먼저 찍었습니다. 지금은 changed가 false면 바로 return해서 경고가 사라집니다. CodeRabbit이 지적한 회귀이고, 경고만 있는 no-op 테스트가 필요합니다.
src/oauth/index.ts reconcileOAuthProviders - 디스크가 missing/invalid이면 throw 합니다. src/server/index.tsstartServerloadConfig() 직후 무조건 이 함수를 호출합니다. 예전에 saveConfig가 기본 설정을 새로 쓰던 첫 기동/홈 비어 있는 경우가, 투영이 바뀔 때 서버 기동 실패로 바뀔 수 있습니다. fail-closed 의도는 맞지만, 첫 기동 계약인지는 확인이 필요합니다.
src/providers/model-rename-startup.ts adoptConfig - 대상 객체의 키를 전부 지운 뒤 structuredClone을 붙입니다. OAuth 쪽 adopt는 만진 필드만 옮기는데, 모델 이름 이전은 전체 교체입니다. 동작은 테스트로 고정돼 있지만, 라이브 객체에 붙어 있던 비설정 부가 상태가 있으면 같이 사라집니다.
src/oauth/index.ts withOAuthReconciliationTouchedKeys - 디스크는 이미 맞춰져 unchanged여도, 라이브 투영이 만진 키를 합쳐서 adopt 합니다. “오래된 메모리만 맞추기” 테스트와 맞는 설계입니다. 다만 unchanged인데도 함수가 true를 반환하므로, 호출부가 “방금 디스크에 썼다”고 오해하면 안 됩니다(현재 startServer는 반환값을 안 씁니다).

메인테이너의 판단이 필요한 지점

  • unsponsored_surface라서 maintainer-sponsored를 붙일지, 보안 리뷰 코멘트를 남긴 뒤 스폰서할지
  • 설정 파일이 없을 때 시작 조정을 throw로 막을지, 예전처럼 첫 저장을 허용할지
  • test(layout): move cli, oauth, routing, claude-integration into tests/<domain>/ (#3497) #3511 이후 테스트 경로만 고쳐 이 브랜치를 살릴지, 동일 커밋을 새 브랜치로 옮겨 닫을지
  • 모델 이름 이전의 전체 adoptConfig가 OAuth의 필드 단위 adopt와 일부러 다른지

너의 추천
머지하지 말고 리베이스하세요. OAuth 테스트 변경은 tests/oauth/oauth-provider-reconcile.test.ts에 두고, no-op 경로에서도 model-rename warnings를 다시 찍게 고친 뒤 draft 체크리스트를 채우세요. 내용이 맞으면 스폰서십 후 랜딩해도 됩니다. #3497 레이아웃 열차(#3513/#3516/#3518)와 파일 충돌은 거의 없으니, 경로만 맞으면 독립적으로 넣어도 됩니다.

The warning-emission finding was valid despite being attached to the pre-rebase SHA. Fixed in 55b5410c3: unchanged model-rename projections now emit their safety warnings before preserving the original config object, with a focused regression test. Current focused verification is 26/26 across model-rename, OAuth reconciliation, and the layout guard; typecheck and privacy scan pass.

Follow-up on the remaining review notes:

  • The branch is now rebased onto the current dev; OAuth and model-rename tests live at their current layout paths, and both layout/hygiene guards pass.
  • Missing/invalid persistence remains intentionally fail-closed. Startup reconciliation must not adopt an uncommitted projection that a later save could publish over newer state; this behavior is explicitly covered by the unavailable-persistence tests.
  • Model-rename adoption intentionally uses the full committed config snapshot. Unlike OAuth reconciliation, which owns a narrow touched-key set, the rename projector can rewrite model references across the config; adopting the authoritative committed snapshot prevents live/disk divergence. OcxConfig is persistence state, not a carrier for runtime-only auxiliary fields.
  • The reconciliation boolean means that live reconciliation/adoption occurred, not necessarily that this invocation wrote bytes. Current startup callers do not interpret it as a write indicator.

The warning regression and stale test paths were fixed; no further code change is warranted for the other points.

lidge-jun pushed a commit that referenced this pull request Sep 5, 2026
reconcileOAuthProviders mutated the in-memory config and called
saveConfig(config), so a startup snapshot overwrote any operator edit made
after loadConfig() returned. runModelRenameStartupMigration had the same
shape. Both now project onto a clone and commit through
mutatePersistedConfig, which rebases the write on the newest on-disk
snapshot, so a concurrent edit survives.

Persistence failure degrades rather than throws. Both functions run inside
startServer (src/server/index.ts:651 and :663), which is synchronous by
design and wraps neither call in try/catch, so a throw there takes the whole
proxy down over a config file the operator can still repair. A missing,
malformed or contended config now warns once and adopts the projection in
memory, matching every other mutatePersistedConfig consumer
(src/storage/policy.ts, src/codex/plan-from-token.ts,
src/server/management/agent-settings-routes.ts).

Adoption is key by key over the touched keys only. A clear-and-reassign
preserves the top-level object identity while silently detaching every
nested sub-object a caller still holds a reference to.

Tests: the concurrent-edit cases are the RED-on-dev proof of the defect
(they fail against unmodified dev, which clobbers). The degrade-not-throw
assertions are RED against #3524's head, which threw. The new
tests/server/server-startup-reconcile-resilience.test.ts covers the boot
path; its /healthz case binds a listener and is skipped where Bun.serve
cannot bind, so it is a hosted-CI-only assertion.

…implementation of #3524) (#3564)

* fix(claude): fall back to native launch when routing is off

`ocx claude` hard-errored and returned 1 whenever Claude routing was disabled
(`src/cli/claude.ts:420` on dev), so the command was unusable with the Claude
toggle off even though a native `claude` binary was available. Launch natively
in that case instead.

Only an explicit `false` triggers the fallback — from config, or reported live
by `GET /api/claude-code` — so a proxy predating the `enabled` field stays
routed, and an absent proxy still starts one rather than falling back.

The native session must not inherit proxy state, so it removes only values it
can prove OpenCodex owns: `ANTHROPIC_BASE_URL` when it targets this proxy's own
loopback host and configured port with a proxy-issued admission token, the
`CLAUDE_CODE_*` discovery and auto-context levers, and model slots that resolve
only through the proxy. An unrelated `http://localhost:8080` gateway and a user
`sk-ant-` credential are preserved. Client-ownership preflight runs before any
fallback, so an invalid or mismatched connected client still fails closed.

Three fixes on top of the contributor's head:

- Sync all eight `docs-site` `guides/claude-code.md` pages, which still
  described `ocx claude` as proxy-only.
- Distinguish an absent `settings.json` from a corrupt one in
  `readPickerDefaultModel`. Swallowing both alike dropped the "saved model
  requires the proxy" warning exactly when the file was broken; a corrupt file
  now warns and names the path without echoing contents.
- Restore the `#764 / SERVICE_STOP_LIVENESS` rationale comment above
  `ensureProxyForClaude`, which the diff deleted while keeping the behavior.

Carry of #3519.

* fix(combos): scope failover cooldowns to the failure's blast radius

A combo failure recorded the same cooldown regardless of what the failure
actually said. An oversized request cooled a healthy target, a per-request
free-tier cap cooled the whole provider for every other combo, and a rejected
credential cooled only the one target that happened to hit it. Meanwhile
pickComboTarget never consulted the cooldown map at all, so a target cooled a
moment earlier was picked again on the next attempt.

ComboFailureCooldownScope gains "none" for request-shape failures (413,
input_admission_refused, context_length_exceeded, tool_catalog_too_large,
cursor_root_envelope_limit, target_incompatible, and the provider hard-cap
overflow), and returns "provider" for 401/402/403 and credential/billing codes.
free_rate_limited leaves isProviderScopedQuotaCap: it is evaluated per request,
so it keeps its hop verdict but stops recording provider-wide evidence.
comboFailureDecision additionally hops model-scoped rejections and 402/425.

Generic 410 and 413 remain terminal, asserted explicitly so a future widening
of the hop list cannot swallow them silently.

"malformed upstream" now infers 502 rather than falling into the generic
"malformed" 400 branch: bytes the upstream mangled are a provider protocol
failure, not a bad client request. Scoped to that phrase, so plain "malformed"
keeps its 400 verdict, and asserted on the message-only path where the existing
structuredServerClass override in httpStatusFromTerminalError cannot absorb it.

Carries the classification half of #3348. Disk persistence of cooldowns and the
policy-fallback status synthesis are deliberately separate and not included.

* fix(providers): recover a key-pool 401 by rotating instead of failing the request

A static API-key pool already rotates on 429 but abandoned the provider on 401,
even though one revoked or mistyped key says nothing about its siblings. Add
rotateKeyOn401/rotateProviderTransportOn401 alongside the 429 pair (sharing the
same persisted-config CAS and transport-rebuild rules) and consult them in the
Responses recovery loop, after the OAuth replay so a refreshable token is never
treated as a dead key. hasKeyPoolFailover already excludes oauth/forward modes.

A 401 is a verdict about the credential, not a timing signal, and upstreams send
no Retry-After for it, so the failed key is held for the full cap rather than the
429 default.

The new key-401 recovery kind is a four-site chain, not one edit: the union in
src/usage/log.ts, the ATTEMPT_RECOVERY_KINDS set that filters it back on read,
the emit site in the Responses loop, and COOLDOWN_RECOVERY_KINDS in routing
analytics. The regression round-trips a persisted attempt through the log file,
because a kind added to the type but missing from the set writes fine and
vanishes on read-back.

Carries the key-401 half of #3348.

* test(providers): pin the 401 rotation cooldown and the third key-pool recovery site

Review round 1 (023): the rotator-count guard now records the pre-stream 401 site (key = 3) and rotateKeyOn401 / rotateProviderTransportOn401 get their own cooldown assertions (MAX_COOLDOWN_MS on 401 vs the 429 default).

Closing as superseded by merged PR #3564 (merge commit 526d4bf). That PR reimplements this persistence-ordering fix on current dev, preserves concurrent edits, adds startup-resilience coverage for unavailable persistence, and includes the required Co-authored-by credit for @yansigit. Rebasing this branch would now duplicate behavior already in upstream.
