Summary

The Codex model picker showed only the six built-in OpenAI models, in both the Codex desktop app and the Codex CLI, on Codex 0.154.0-alpha.6.2. The on-disk catalog was correct the whole time (24 models), and ocx sync printed Model catalog synchronized, so the failure looked like a success.

Current Codex writes paginated rollout files whose first JSONL line carries an ordinal field. assertLegacyHistoryRecord refuses any such record, so preflightCodexHistoryInjection refuses unconditionally on every current Codex home. injectCodexConfig used that refusal as a hard veto on the entire config write, so model_catalog_json and the routing keys never reached config.toml. syncModelsToCodex then special-cased exactly that reason and downgraded it to a catalog-only result with ok: true, which is what made the regression silent.

What this changes, on the apply direction only:

  • history_paginated_requires_native_writer now stands the conversation-history relabel unit down instead of vetoing the transition. Config, profile, and model_catalog_json are written, the relabel job is skipped without spawning its Worker, and the reason travels in the message and in historyPreflightFailureReason beside success: true.
  • That is the only reason treated this way, because Codex allocates paginated rollout ordinals in its own writer and no retry changes that. An unreadable state database, a rollout whose identity changed, or a preflight that could not run may all succeed on the next attempt, so they keep the hard refusal and the compensating rollback — including when observed mid-transaction. Recording them as a stand-down would let resolveCodexHistoryTransition mark the transition converged and suppress the relabel permanently.
  • Rows tagged opencodex resolve only through [model_providers.opencodex]. The loopback form retires that table precisely because the relabel migrates those rows back to openai in the same pass, so retiring it with the relabel stood down would orphan every such conversation. A table the home already published now survives the write.
  • sync.ts loses the catalog-only downgrade, so a refusal that survives is a real config or integrity failure again.

Deliberately out of scope. Restore and removal keep their refusal. There the argument reverses: stripping the provider definition while its threads still point at it orphans them, and those paths have no seam for keeping a compatibility table. An already-paginated home therefore still cannot be uninstalled through the product. That is recorded as open follow-up work in devlog/_plan/260914_codex_history_preflight_scope/, not shipped half-done.

Paginated rollout bytes and thread rows are never modified in any of these states.

Verification

  • bun run typecheck — pass
  • bun run structure:check — pass (structure/ SSOT checks passed)
  • bun run privacy:scan — pass (Privacy scan passed)
  • Live recovery on an affected machine: ocx sync now writes model_catalog_json and openai_base_url, prints the stood-down relabel warning, and the model picker recovered in both the Codex app and the CLI (maintainer-confirmed).
  • Regression coverage in tests/codex-integration/codex-inject-integration.test.ts: the commit-boundary case now asserts the config commits and the relabel retires; the paginated case asserts the config is written and an existing provider table survives while restore keeps refusing; a new case pins that model_catalog_json reaches config.toml on a paginated home. tests/codex-integration/codex-sync-api.test.ts replaces the two catalog-only downgrade tests with the applied-plus-warning contract and with proof that a surviving refusal is no longer dressed up as a catalog success.
  • Docs: structure/config.md plus the Codex integration guide and its seven locales.
  • The local suite was deliberately not run during an active incident on the maintainer's machine, because tests/codex-integration/ contends with the running Codex app-server. CI is the verification gate.

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

    • Codex configuration, profiles, and model catalogs now update when paginated history requires Codex’s native writer.
    • Restore and configuration removal remain blocked by this condition.
    • Existing paginated conversation history remains unchanged, while new conversations continue routing normally.
    • CLI results identify skipped history relabeling and provide the native-writer reason.
    • Explicit sync failures are now reported accurately instead of being treated as catalog-only success.
  • Documentation

    • Updated integration guidance across supported languages with revised behavior and recovery precautions.

A paginated rollout makes `preflightCodexHistoryInjection` refuse
unconditionally, and that refusal vetoed the whole config write. So
`model_catalog_json` never reached config.toml and both the Codex app and the
CLI fell back to their built-in model list, while `ocx sync` still reported
success because `sync.ts` downgraded that one reason to `catalog-only`.

The refusal now stands down only the conversation-history relabel unit, in
every direction. Config, profile, and catalog always write, the relabel job is
skipped without spawning its Worker, and the reason travels in the message and
in `historyPreflightFailureReason` beside `success: true`. A store that
migrates mid-transaction retires the relabel unit instead of rolling the config
back.

Restore and removal get the same treatment. They open no state database and no
rollout, so the preflight never authorized them, and three routed thread rows
out of 14164 were enough to deadlock apply, removal, and restore at once.

Paginated rollout bytes and thread rows are still never modified.

📝 Walkthrough

Walkthrough

The change scopes history_paginated_requires_native_writer to conversation-history relabeling. Configuration, profile, catalog, and sync operations now proceed independently. Restore and removal remain hard refusals. Tests, configuration documentation, and localized guides describe the updated behavior.

Changes

History preflight contract

Layer / File(s) Summary
Contract and documented scope
devlog/_plan/260914_codex_history_preflight_scope/*, structure/config.md
The refusal now affects only history relabeling. Configuration, profile, and catalog writes continue. Other refusal reasons still fail and roll back. The catalog-only sync result is removed.
Apply and restore behavior
src/codex/inject.ts
Apply records the refusal, continues configuration writes, preserves an existing OpenCodex provider table when needed, skips the history worker, and reports delegation to Codex’s native writer. Restore and removal remain refused.
Sync result handling
src/codex/sync.ts
Paginated-history refusals use the shared failure path when configuration does not complete. Successful configuration writes expose a native-writer warning.
Tests and integration guidance
tests/codex-integration/*, docs-site/src/content/docs/*/guides/codex-integration.md
Tests verify configuration and catalog writes, provider-table preservation, untouched paginated history, restore refusal, and true sync failures. Localized guides describe the same behavior.

이 PR은 Codex 0.154 계열에서 모델 선택기가 갑자기 내장 6개만 보이는 사고를 고칩니다. 디스크의 카탈로그는 24개로 정상이고 ocx sync도 성공처럼 보이는데, 앱·CLI 둘 다 선택기가 비어 보이는 증상입니다. 원인은 한 줄로 말하면 이렇습니다. 지금 Codex는 페이지네이션된 rollout을 쓰고, 그 첫 JSONL에 ordinal이 있습니다. assertLegacyHistoryRecord는 그런 기록을 거절하고, preflightCodexHistoryInjection은 현재 Codex home마다 거의 항상 거절합니다. 그런데 injectCodexConfig가 그 거절을 설정 쓰기 전체 거부로 썼고, syncModelsToCodex는 그 이유를 catalog-only + ok: true로 내려서 조용히 성공처럼 보이게 만들었습니다. 그래서 model_catalog_json과 라우팅 키가 config.toml에 안 들어가고, 사용자는 sync 성공 메시지만 봤습니다.

지금 dev(HEAD df7dc1be5, package.json 2.54.0)는 아직 옛 계약입니다. src/codex/inject.ts의 apply 경로는 history preflight 실패면 success: false로 바로 돌아가고, removeCodexConfig와 restore의 config half도 같은 preflight로 막습니다. src/codex/sync.ts는 history_paginated_requires_native_writer만 골라 catalog-only로 완화합니다. 이 PR은 경계를 고칩니다. history preflight 거절은 대화 히스토리 relabel 유닛만 세웁니다. config·profile·catalog는 항상 쓰고, Worker는 안 띄우며, 이유는 historyPreflightFailureReason에 success: true와 같이 실립니다. remove·restore도 같은 경계로 맞춰서, 페이지네이션 home에서 uninstall/restore가 막히던 한쪽 문을 엽니다. catalog-only 다운그레이드는 지워서, 살아남은 거절은 다시 진짜 config/integrity 실패가 됩니다. rollout 바이트와 thread row는 여전히 안 고칩니다. 이미 opencodex로 태그된 옛 스레드는 후속으로 남겨 두었습니다.

왜 점수가 높은가. 현재 Codex 런타임에서 picker가 깨지는 사고성 회귀이고, 작성자(유지보수자)가 영향 머신에서 live recovery까지 확인했습니다. 범위도 inject/sync/structure/테스트/다국어 가이드로 맞고, types.ts/config.ts 분리 캠페인과도 충돌하지 않습니다. CI 제품 suite는 아직 돌아가는 중이고 로컬 suite는 의도적으로 안 돌렸다고 했으니, tip CI 초록이 최종 게이트입니다. 그래서 78~79가 아니라 77로 둡니다.

라인 - src/codex/inject.ts CodexInjectResult JSDoc - apply에서는 historyPreflightFailureReason이 실패가 아니라고 쓰면서, 바로 아래 문장은 restore/remove가 여전히 outright refuse한다고 적혀 있다. 본문·코드는 restore/remove도 config half는 진행한다. 주석이 새 계약과 어긋나니 머지 전에 한 줄 고치는 편이 안전하다.
라인 - src/codex/inject.ts apply historyRelabelRefusal - preflight 거절을 veto에서 stand-down으로 바꾼다. validateOnly도 success: true + reason을 돌려준다. src/client/connect.ts는 !preflight.success만 보므로, 이 변경 후 connect도 config 주입으로 넘어간다(의도된 방향).
라인 - src/codex/inject.ts applyNativeArtifacts / mid-transaction preflight - 예전에 CodexHistoryPreflightRefusal로 config를 롤백하던 경로를 없앴다. mid-migration은 relabel만 접고 config는 남긴다. 계약 주석과 일치하는지 한 번 더 확인하면 좋다.
라인 - src/codex/inject.ts removeCodexConfig / restore config half - history preflight veto를 제거한다. uninstall·restore가 페이지네이션 home에서 막히던 문제를 푼다. history 유닛은 skip 메시지로 남긴다.
라인 - src/codex/sync.ts - catalog-only 특별 처리를 지우고, 성공+reason이면 warning에 실는다. picker 회귀를 숨기던 경로를 없앤 핵심이다.
경로/심볼 - structure/config.md + docs-site 다국어 codex-integration.md - SSOT와 가이드가 새 경계를 같이 말한다. structure 체크 통과 주장과 맞다.
경로/심볼 - tests/codex-integration/codex-inject-integration.test.ts / codex-sync-api.test.ts - 옛 veto·catalog-only 계약을 뒤집고, paginated home에서 model_catalog_json이 쓰이는지·warning이 도는지 고정한다. 로컬 suite는 돌리지 않았고 CI가 게이트다.
경로/심볼 - 이미 opencodex 태그된 thread - provider 테이블이 있어야 resolve된다. 이번 PR이 건드리지 않는 선재 한계다. follow-up 이슈로 열지 여부는 메인테이너 판단이다.

메인테이너의 판단이 필요한 지점

  • tip Cross-platform CI(test/macos/npm-global/docker 등)가 초록이 되면 바로 dev에 머지할지
  • opencodex-tagged legacy thread를 native writer 없이 resolve하는 follow-up을 이번 릴리즈 노트에 명시할지, 아니면 별도 이슈만 열지
  • historyPreflightFailureReason 이름을 success와 같이 쓰기 어색하니, 후속으로 historyRelabelStandDownReason 같은 rename을 받을지(이번 PR 범위 밖이어도 됨)
  • CodexInjectResult JSDoc의 restore/remove 문장을 코드에 맞게 고칠지(리뷰어 권장: 예)

너의 추천
사고 수정이고 live 확인까지 끝났으니, tip CI 초록 확인 후 바로 merge하라. JSDoc 한 줄 불일치는 머지 전 마이크로 커밋으로 고치거나 바로 이은 follow-up으로 고쳐라. types/config 분리와 무관하니 close-don't-rebase 대상이 아니다. 이미 태그된 legacy thread는 이 PR에 억지로 넣지 말고 후속으로 남겨라.

P1 Badge Retain the provider table when relabeling is refused

When a normal loopback sync upgrades an existing provider-table installation containing paginated rows tagged opencodex, the earlier transform removes [model_providers.opencodex], and this branch then skips the relabel that would change those rows back to openai. Codex can no longer resolve the retained opencodex provider IDs, so previously resumable conversations become inaccessible; the old refusal preserved the table. Keep a compatibility provider table, or decline this routing-form conversion, whenever the rows cannot be relabeled.

P1 Badge Preserve routing while paginated restore work remains

For an authless or legacy installation whose paginated history still references opencodex, this branch skips the restore worker only after the config and catalog halves have removed that provider, then returns overall success. The thread rows and rollout metadata remain routed while their provider definition is gone, defeating restore's purpose of keeping conversations resumable. The unchanged focused cases in tests/codex-integration/codex-inject-integration.test.ts at lines 71-111 and 285-363 still require preservation or compensation for exactly this state, so the subsystem suite also remains contradictory; retain compatible routing until metadata is restored, or fail and compensate the config transition.

P2 Badge Keep failed preflights out of the converged state

historyRelabelRefusal covers every non-null preflight result, including history_injection_preflight_unavailable, missing-state, and rollout-integrity errors—not only the permanent paginated-format refusal. Converting all of them to kind: "skipped" causes resolveCodexHistoryTransition to record the transition as converged with no retry, so a transient SQLite read/query failure permanently suppresses relabeling and hides outstanding work from convergence diagnostics. Use a blocked or unknown outcome for operational/integrity failures, reserving a completed skip for an explicit opt-out or a deliberately terminal condition.

The entry preflight and a mid-write recheck report the same refusal string but
mean different things, and collapsing them is what left this home unable to
uninstall.

A store that migrates while the restore is writing is new information: history
was restorable when the operation began, so abandoning it and compensating the
pre-images keeps config and history consistent. Stripping a provider definition
while its threads still point at it would orphan them.

A store already paginated at the entry preflight is not new information. There
the relabel was never available, and refusing only means OpenCodex can never be
removed. Those rows are equally unresolvable either way, so the config half
proceeds and the caller reports the stood-down history unit.

…the journal

A baseline that is already routed writes no journal, so journal presence is not
evidence the artifact transaction committed. The profile is replaced inside that
transaction in every form, so no longer holding the fixture sentinel is.

Also updates the manifest-owned restore case: those rows are already native, so
removing the config orphans nothing and the manifest survives for a later native
writer. Refusing was what made a paginated home impossible to uninstall.

Co-authored-by: Cursor <cursoragent@cursor.com>
Review found two real defects in the first cut.

Only `history_paginated_requires_native_writer` stands the relabel unit down,
because Codex allocates paginated rollout ordinals in its own writer and no
retry changes that. An unreadable state database, a rollout whose identity
changed, or a preflight that could not run may all succeed next time, so they
keep the hard refusal and the compensating rollback. Recording them as a
stand-down would mark the transition converged and suppress the relabel forever.

Rows tagged `opencodex` resolve only through `[model_providers.opencodex]`. The
loopback form retires that table precisely because the relabel migrates those
rows back to `openai` in the same pass, so retiring it with the relabel stood
down would orphan every such conversation. A table the home already published
now survives the write.

Restore and removal keep their refusal. There the argument reverses: stripping
the provider definition while its threads still point at it orphans them, and
those paths have no seam for keeping a compatibility table. An already-paginated
home therefore still cannot be uninstalled through the product; that is recorded
as open work rather than shipped half-done.

Preserve the existing provider table contents.

removeOcxSection removes the existing provider table and its subtables before preflight. buildProviderTableBlockForTarget then writes only canonical fields. This can discard custom fields, subtables, and existing authentication configuration.

When historyRelabelRefusal is active and providerTableMode is false, capture the complete provider table before cleanup and restore those bytes instead of rebuilding the table. The rows remain tagged opencodex, so retaining the existing table is compatible with the stood-down routing transition. The current test at tests/codex-integration/codex-inject-integration.test.ts:369-399 checks only the table header and would not detect this loss.

Maintainer self-integration into dev

Recording the decision and exact-head CI evidence required by MAINTAINERS.md for integrating a maintainer's own pull request into dev without a second approval.

Decision. Integrate now. This is an active incident fix: on Codex 0.154.0-alpha.6.2 every install lost its OpenCodex model list because a paginated-history preflight vetoed the config write, and ocx sync reported that failure as success. Holding the fix for a second reviewer keeps every current Codex home broken.

Exact head. b484a89964aa76465c1ac925ae03ab5445cf91bd

CI at that head. 25 checks pass; the only non-pass entries are the two intentional skipping placeholders (the Windows shard matrix expansion and macos control). All four Linux test shards, both macOS shards, gates, hygiene, enforce-target, storage policy, api usage, the three keyring jobs, the three npm-global jobs, docker smoke, and react-doctor are green: https://github.com/lidge-jun/opencodex/actions/runs/34772128322

Review findings. The automated Codex reviewer raised two P1 findings and one P2 on the first revision; all three are addressed in b484a89, and the review surface is clean at this head. CodeRabbit's findings are addressed or answered. Two of those findings caused a deliberate scope reduction: the restore and removal softening was reverted, so this PR changes the apply direction only.

Outstanding objections. None open. The known limitation — an already-paginated home still cannot be uninstalled through the product — is recorded as follow-up work in devlog/_plan/260914_codex_history_preflight_scope/ rather than left implicit.

Security review. Not required. No authentication, credential, token, OAuth, workflow, release-automation, or dependency-installation surface is touched. bun run privacy:scan passes.

Three leftovers from scoping the history preflight, found by re-reading the
owned docs against the shipped behaviour.

`codex-home.md` still said a detected migration always restores all three
preimages before refusing. That is now direction- and reason-dependent: on apply
the paginated refusal retires the relabel unit and the write stands, because it
is permanent and compensating it produced a home with no OpenCodex models at
all. Every other reason there still compensates, and restore and removal
compensate on all of them, because retiring a provider definition its thread
rows still name would orphan them.

The unattended-sync test stubbed the injector returning a paginated refusal,
which it can no longer produce, so the test guarded an unreachable shape while
still passing. It now stubs an operational reason, which is still a hard refusal.

One preflight test claimed to assert that provider definitions are preserved;
it asserts which target sets reach a paginated row. Renamed to match.

* fix(codex): scope the history preflight to the relabel unit

A paginated rollout makes `preflightCodexHistoryInjection` refuse
unconditionally, and that refusal vetoed the whole config write. So
`model_catalog_json` never reached config.toml and both the Codex app and the
CLI fell back to their built-in model list, while `ocx sync` still reported
success because `sync.ts` downgraded that one reason to `catalog-only`.

The refusal now stands down only the conversation-history relabel unit, in
every direction. Config, profile, and catalog always write, the relabel job is
skipped without spawning its Worker, and the reason travels in the message and
in `historyPreflightFailureReason` beside `success: true`. A store that
migrates mid-transaction retires the relabel unit instead of rolling the config
back.

Restore and removal get the same treatment. They open no state database and no
rollout, so the preflight never authorized them, and three routed thread rows
out of 14164 were enough to deadlock apply, removal, and restore at once.

Paginated rollout bytes and thread rows are still never modified.

* fix(codex): only roll a restore back when the store migrates mid-write

The entry preflight and a mid-write recheck report the same refusal string but
mean different things, and collapsing them is what left this home unable to
uninstall.

A store that migrates while the restore is writing is new information: history
was restorable when the operation began, so abandoning it and compensating the
pre-images keeps config and history consistent. Stripping a provider definition
while its threads still point at it would orphan them.

A store already paginated at the entry preflight is not new information. There
the relabel was never available, and refusing only means OpenCodex can never be
removed. Those rows are equally unresolvable either way, so the config half
proceeds and the caller reports the stood-down history unit.

* test(codex): pin the transaction-committed proof to the profile, not the journal

A baseline that is already routed writes no journal, so journal presence is not
evidence the artifact transaction committed. The profile is replaced inside that
transaction in every form, so no longer holding the fixture sentinel is.

Also updates the manifest-owned restore case: those rows are already native, so
removing the config orphans nothing and the manifest survives for a later native
writer. Refusing was what made a paginated home impossible to uninstall.

* fix(codex): narrow the stand-down and keep the table its rows need

Review found two real defects in the first cut.

Only `history_paginated_requires_native_writer` stands the relabel unit down,
because Codex allocates paginated rollout ordinals in its own writer and no
retry changes that. An unreadable state database, a rollout whose identity
changed, or a preflight that could not run may all succeed next time, so they
keep the hard refusal and the compensating rollback. Recording them as a
stand-down would mark the transition converged and suppress the relabel forever.

Rows tagged `opencodex` resolve only through `[model_providers.opencodex]`. The
loopback form retires that table precisely because the relabel migrates those
rows back to `openai` in the same pass, so retiring it with the relabel stood
down would orphan every such conversation. A table the home already published
now survives the write.

Restore and removal keep their refusal. There the argument reverses: stripping
the provider definition while its threads still point at it orphans them, and
those paths have no seam for keeping a compatibility table. An already-paginated
home therefore still cannot be uninstalled through the product; that is recorded
as open work rather than shipped half-done.
