Conversation
📝 WalkthroughWalkthroughAdds opt-in Codex context management support. The proxy rewrites managed loopback configuration, aliases Codex backend routes, forwards native history and notes requests, preserves authentication and upstream responses, and adds integration tests and documentation. ChangesCodex context management
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Standard bearer-authenticated context requests can fail, and an incomplete fix could expose the proxy credential upstream. Malformed Codex configuration can also prevent managed injection. Resolve these issues before merging. Sequence Diagram(s)sequenceDiagram

In `@docs-site/src/content/docs/guides/codex-integration.md`:
- Around line 79-82: Update the Codex context-history documentation around the
ChatGPT forward-provider section to explicitly reference the built-in openai
provider and openai-responses adapter. Document that direct uses the current
login, pool selects a Codex account, only authorization, ChatGPT account ID, and
approved OpenAI beta/originator/session headers are forwarded, while
openai-apikey and custom or noncanonical Responses providers do not use Codex
accounts; state that affinity, cooldown, and retry behavior is unchanged and
forward requests do not use same-key 429 replay.
In `@src/codex/context-compat.ts`:
- Line 28: Update contextCompatibleBaseLine to catch malformed TOML parsing
errors from Bun.TOML.parse and return the original line unchanged. Preserve
user-owned openai_base_url values and disabled context-management behavior, and
add a regression test in the Codex injection integration tests.
In `@src/server/context-history.ts`:
- Line 44: Update the context-history admission flow around
validateForwardAdmissionCredential so bearer admissions are passed into context
selection with substituteMainCredentialForDirect enabled and materialized with
substituteMainCredential enabled. Preserve a final no-forwarding check, ensuring
context validation executes and the upstream never receives the data-plane key.

리뷰 · 우선순위 61 / 80설명 이 드래프트 PR은 Codex 0.153의 실험용 context management를 OpenCodex 루프백에서도 쓰이게 하려는 작업입니다. 공식 Codex는 내장 OpenAI provider base URL이 변경은 세 층입니다. 방향은 Codex 신기능 호환에 필요하고, 계정 풀 정책을 새로 쓰지 않은 점도 좋습니다. 다만 인증된 중계면이라 보안 리뷰가 필수입니다. 세션 친화도가 process-local이고 계정 마이그레이션이 없다는 한계도 본문에 명시되어 있습니다. 드래프트이고, 실험 플래그를 켠 사용자에게만 경로가 바뀌는지·remote custom provider에 새 경로가 새지 않는지·관리 API admission과 키가 있는 live-call 라우팅이 같은지 exact-head에서 한 번 더 잠가야 합니다. types/config 대형 분할 캠페인과는 겹치지 않아 닫을 이유는 없습니다. 경로 메인테이너의 판단이 필요한 지점

Supporting follow-up for the three public CodeRabbit findings: commit 9fe11948 (patch). It is one commit directly on this PR's current The follow-up handles malformed TOML without disrupting user-owned routing, passes trusted bearer admission into existing Codex credential selection/materialization, checks the assembled outgoing headers for proxy credentials, and clarifies provider eligibility, forwarded headers, and retry behavior. Regressions cover the real listener and stored-main credential path as well as the focused relay contract. Verification in an isolated Bun 1.4.0 Linux container:
All tests used synthetic data with no network, host mounts, credentials, or published ports. Live ChatGPT history/notes and native macOS/Windows behavior were not tested. This is a supporting contribution, not a merge-readiness claim; maintainer security review and required upstream CI remain necessary. Prepared with AI assistance and a separate manager review of the executor's changes. Thanks for implementing the original context-history and notes relay. |

Two targeted follow-up suggestions from subsequent testing, complementing my earlier review-fix contribution. 1. Add an explicit-account continuity regression. The PR already documents Pool switching and process-local affinity limits. A specific case worth checking is an explicitly pinned model account differing from the active Pool account, even without a restart. At Suggested regression: configure accounts A/B with B active in Pool; send a successful model request explicitly pinned to A; then send a history/notes request for that root 2. Document a checkpointed transition for existing sessions. On macOS, official Codex CLI 0.153.1 with a local OpenCodex 2.42.0 backport plus additional account-ownership checks, we tested: create a synthetic session with the experiment off → cold-resume the same ID/account with it on → write and read back a checkpoint containing both old facts → native In a separate small test, a pre-activation history marker was not recovered after a reset, including after correcting the history-call arguments. That observation does not establish backend retention/backfill guarantees. A useful documentation note would be: reload existing sessions, preserve needed pre-activation state in a verified checkpoint before the first reset, and do not assume automatic history backfill. Codex's resume/compaction protocol also distinguishes rejoining loaded threads from loading with new configuration. These are synthetic compatibility observations, not exact-head CI or desktop-UI validation. The successful migration used native manual compaction; it does not establish reliable autonomous reset-tool selection. Prepared with AI assistance; no private session logs or account identifiers are attached. |
Apply the context review fixes for forward documentation, malformed feature configuration, and admission-aware credential materialization. Record the account from the accepted model attempt and reject unknown or conflicting history ownership. Co-authored-by: nbbb26 <259064678+nbbb26@users.noreply.github.com>

Summary
Codex 0.153's experimental context management requires the built-in OpenAI provider base URL to end in
/backend-api/codex. OpenCodex injects/v1, so enabling the feature does not expose the native history/notes tools; changing the path alone then reaches missing endpoints./v1routes and realtime sideband overrides. Malformed TOML leaves the feature disabled.The authenticated relay still requires maintainer security review before merge. The documentation, malformed-TOML and initial admission fixes incorporate nbbb26's contribution, credited in the commit.
Verification
Final revision
8e0b53b:bun scripts/test.ts --changed=dev, resolved comparison merge basebf58ef1824e7b827b2a6bc1a5effb5d36ce80180): 11,463 passed, 3 skipped, 0 failed across 600 files.The earlier implementation's full run passed 19,239 tests with 14 skips, but that result predates this revision and is not its full-suite verification. Earlier real CLI smoke tests likewise predate the ownership registry; final runtime activation and real-account smoke verification remain separate from these simulated regressions.
Hosted CI on the previous head was awaiting maintainer action. This remains a draft; local checks are not a claim that hosted CI is green.
