Summary

Closes #5710.

  • Emit session_affinity_header: session-id for every generated Hermes OpenCodex provider. This is a header name; Hermes supplies the dynamic conversation value. There is no static identifier, protocol switch, or upstream forwarding change.
  • Let Apply upgrade an existing owned block, including the exact manually added workaround. Client/path ownership must match, and removing only the supported affinity field must reproduce the previous exact or recorded semantic fingerprint. Other edits still conflict; after adoption, changing or deleting affinity is protected.
  • Keep legacy configuration and catalog refresh pending until explicit Apply. Subsequent refresh and Replace retain affinity. Reuse YAML source preservation, snapshots, and Restore; document the upgrade and required Hermes support in English and localized notes.
  • Unblock full local validation in a separate test-only commit: keep host DNS out of metadata/stubbed-transport fixtures, bind service-home fixtures to their own test environment, and run the affected launcher/service/admission files through the existing fresh-process roster. All test assertions and file membership are retained. Six metadata cases moved to a sibling file to respect the line cap, with their original Windows timeout preserved.

Verification

Validated head: 43947f53f32f543e8fbd4592654df668f4719a5b.

  • bun run test --parallel=2 — passed, exit 0 on the head above: 30398 passed / 60 existing skips / 0 failed, all 1,603 test files, all 19 singleton lanes completed, 705 seconds. The worker-count override changes concurrency only; the full-suite selector, assertions, process deadlines and test membership are retained.
  • bun run typecheck, bun run structure:check, bun run privacy:scan — passed.
  • bun test tests/clients/integrations-hermes-affinity.test.ts — 20 passed; the pre-fix run reproduced both missing affinity and manual-workaround conflicts.
  • Related existing configuration/state/writer coverage — 150 passed. New regression plus both layout guards — 38 passed.
  • bun run test tests/codex-integration/native-codex-toggle.test.ts tests/server/management-provider-context-windows.test.ts tests/ci-workflows/test-runner.test.ts — 75 passed / 3 platform skips / 0 failed after the final fixture correction.
  • cd docs-site && bun install --frozen-lockfile && bun run build — passed, 505 pages and 67,100 internal links checked.
  • Independent local Standards/Spec and test-repair reviews found no unresolved findings. Ownership review checked client/path/fingerprint binding, protection after adoption, restoration, and case-local test mocks. Maintainer security review and required current-head CI remain prerequisites to merge.
Why the initial full run failed, and what changed

The initial run under the Codex-managed home encountered the repository's real-home deletion guard. Validation was moved to an ordinary user-owned checkout outside both that protected directory and the shared /tmp executable ancestry; neither guard was bypassed.

A subsequent bun run test recorded 22 failures and hit the 900-second process limit in ocx-launcher-runtime.test.ts. Those results were not treated as passing. Diagnosis found:

  • Host fake-IP DNS rejected provider metadata fixtures before their asserted behavior. Five case-local existing destination-probe mocks and the six moved metadata cases isolate that external prerequisite; production destination validation and dedicated rejection tests are unchanged.
  • A cross-process test stubbed HTTP but still performed real DNS validation, repeatedly failing to reach its barrier. Its fixture now explicitly allows its stubbed route; the same real mutation/catalog assertions went from a 45-second timeout to approximately 0.9 seconds in isolation and 1.5 seconds under the full run.
  • os.homedir() in Bun retained the startup home, so changing the test's config home was insufficient. The service-claim fixture now pins the home lookup and restores it afterward.
  • A toggle fixture observed the developer's live launchd registration instead of a test-owned service. It now uses the repository's existing ownedServiceHomeInspection helper; dedicated ownership-fencing tests are untouched.
  • Launcher probes and service/native-admission fixtures now run in existing bounded singleton lanes. This changes process isolation, not assertions, deadlines, or selected test membership.

The first repaired full command completed its main queue with 29,721 passes / 35 skips / 0 failures and exposed the toggle-fixture issue. After that correction, the next complete run passed the toggle but exposed a separate one-second destroyed-shim cold-start timeout. That unchanged FIFO assertion now also has a singleton lane. The final head is validated with the full command and two workers; membership is unchanged and the final result is not synthesized from partial reruns.

Hermes compatibility: helper-level assertions against 67f7e1d6b3115b8812caa58156c0f9b5531af072 checked configured route lookup, distinct conversations, retained root scope across supplied compaction/child IDs, auxiliary scope, and declared-scope precedence in an isolated home. Older revisions may ignore/drop the field; actual affinity requires a supporting Hermes version. Records without a semantic fingerprint still require exact prior key order. No live HTTP/cache benchmark or guaranteed hit rate is claimed. Conventional Chat/Responses forwarding rules and separate live/realtime forwarding rules are unchanged.

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.

Review readiness

  • Required local validation passed; commands, results, and any full-suite exception are documented.

  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

  • New Features
    • Hermes integrations now include session affinity for provider models, using a dynamic session ID rather than a fixed value.
    • Existing managed Hermes integrations can adopt this setting with Apply when it is the only change. Other managed-field changes remain conflicts, and model-list refresh waits until the update is applied.
  • Documentation
    • Updated integration guides to explain compatibility requirements and note that session affinity does not guarantee cache hits.

📝 Walkthrough

Walkthrough

The PR adds dynamic session-affinity configuration to generated Hermes integrations and defines how managed integrations adopt it. It also adds provider context-window tests and updates test isolation and serial-lane coverage.

Changes

Hermes session affinity

Layer / File(s) Summary
Emit the Hermes affinity setting
src/clients/config-export.ts, tests/config/client-config-export-new-clients.test.ts
Generated Hermes provider configuration now includes session_affinity_header: "session-id". The test checks the exported value.
Classify and apply the upgrade
src/integrations/ownership-policy.ts, src/integrations/state.ts, src/integrations/writer.ts, src/integrations/owned-refresh.ts
Ownership policy recognizes the specified Hermes affinity-only upgrade. Classification allows that case, while refresh leaves a matching legacy configuration unchanged and reports it as stale until Apply.
Verify and document the lifecycle
tests/clients/integrations-hermes-affinity.test.ts, structure/clients/integrations.md, docs-site/src/content/docs/*/guides/integrations.md, docs-site/src/content/docs/guides/integrations.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
Tests cover adoption, conflicts, refresh, restore, and disable. The integration documentation describes the setting and upgrade behavior across the listed locales.

Provider context-window coverage

Layer / File(s) Summary
Test context-window persistence
tests/server/management-provider-context-windows.test.ts, tests/server/management-provider-validation.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
Adds Windows-focused tests for provider context-window persistence and PATCH removal. Removes the prior context-window test block from the provider validation suite and maps the new test in the test-layout files.

Test isolation and serial lanes

Layer / File(s) Summary
Isolate test fixtures from host state
tests/codex-integration/codex-retained-root-serialization.test.ts, tests/codex-integration/native-codex-toggle.test.ts, tests/service/service-claim.test.ts, tests/server/management-provider-validation.test.ts
Test fixtures mock native ownership and the OS home lookup, add destination-resolution stubs, and allow private-network access for a local stub fetch.
Run selected tests in serial lanes
scripts/test.ts, tests/ci-workflows/test-runner.test.ts, structure/ops/docs-and-release.md, structure/ops/test-sandbox-cleanup.md
Adds test files to the serial full-suite roster, checks that they receive --parallel=1, and documents the process and sandbox isolation requirements.

Explanation

The PR contains demonstrated changes unrelated to Hermes session-affinity generation or ownership lifecycle. Examples include the new Windows provider context-window suite in tests/server/management-provider-context-windows.test.ts, removal and fixture changes in tests/server/management-provider-validation.test.ts, service-home and native-toggle fixture changes in tests/service/service-claim.test.ts and tests/codex-integration/native-codex-toggle.test.ts, and broad serial-lane changes in scripts/test.ts. The summary identifies these as separate full-suite fixture repairs. They do not implement or test Issue #5710 behavior.

Resolution

Move the unrelated provider-context-window, service/native fixture, launcher, and serial-lane repairs to a separate pull request, or provide a direct Issue #5710 requirement that makes each change necessary. Keep only Hermes implementation, Hermes tests, related documentation, and narrowly required test infrastructure in this pull request.

Full details: Docstring Coverage

Explanation

Docstring coverage is 28.57% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 14 functions across 14 files. (13 skipped: 13 unsupported.)

이 PR은 Hermes 연동 블록에 session_affinity_header: session-id를 넣습니다. 이 값은 헤더 이름입니다. 대화마다 바뀌는 실제 ID는 Hermes가 채웁니다. 새로 연결하는 Hermes는 처음부터 이 줄이 들어갑니다.

이미 연결된 Hermes는 사용자가 Integrations에서 Apply를 눌러야 바뀝니다. 그 전에는 화면이 업데이트가 필요하다고 보여주고, 자동 갱신은 설정 파일과 소유 기록을 그대로 둡니다. 모델 목록도 그때까지 그 통합에서는 갱신되지 않습니다.

예전에 그 한 줄만 손으로 넣은 경우는 충돌에서 빠져 Apply로 받아들일 수 있습니다. 조건은 세 가지입니다. 소유 기록의 클라이언트와 파일 경로가 맞고, 그 필드를 뺀 블록의 지문이 이전 기록과 같아야 합니다. 다른 칸을 고쳤거나 헤더 이름이 다르거나 소유 기록이 없으면 예전처럼 충돌입니다. Apply 이후에는 이 칸을 지우거나 다른 값으로 바꾸는 것도 충돌로 막습니다. 바깥의 다른 YAML과 주석은 그대로 두고, 기존 스냅샷과 Restore를 재사용합니다.

src/integrations/owned-refresh.ts - 갱신 결과가 성공이면서 최신이 아니면 state는 빠지고 reason만 붙습니다. ok와 changed: false만 보는 쪽은 갱신이 끝난 것으로 읽을 수 있습니다. 지금 Hermes는 ocx sync 자동 갱신 목록(mcode, pi, raycast, omo, cline)에 없습니다. 이 멈춤은 refreshIntegration을 직접 부를 때 동작합니다.

src/clients/config-export.ts - 헤더는 Hermes의 OpenCodex provider 전체에 붙습니다. Codex 모델이 아닌 요청도 로컬 OpenCodex로 대화 ID를 보냅니다. 업스트림으로 넘기는 헤더 목록은 이 PR이 바꾸지 않았습니다.

PR 본문 - 이 PR은 초안입니다. 준비 체크는 4칸 중 1칸입니다. 전체 bun test는 아직 도는 중이고, provider-management 실패를 base와 비교 중이라고 적혀 있습니다. 그 결과가 본문에 적혀야 검증 기록이 생깁니다.

메인테이너의 판단이 필요한 지점

이미 연결된 Hermes의 모델 목록 갱신을 Apply 전까지 멈추는 선택이 맞는지 정하면 됩니다. 작성자는 사용자가 모르게 새 설정이 켜지는 것을 막으려고 이렇게 골랐습니다. 헤더는 Apply 때 넣고, 모델 목록은 그 전에도 갱신하는 쪽이 가능한 다른 선택입니다.

옛 Hermes가 모르는 키를 만나면 설정 로드를 거절하는지도 보면 됩니다. 이 PR은 버전을 검사하지 않고, 문서에는 옛 버전이 이 옵션을 무시하거나 버릴 수 있다고 적혀 있습니다.

session-id가 Codex가 아닌 업스트림으로 나가는지 확인이 필요합니다. 실시간 통화 쪽 LIVE_CLIENT_PROTOCOL_HEADERS에는 이 이름이 들어 있습니다. 일반 모델 요청의 전달 목록은 이번 변경에 없습니다.

소유 기록에 semantic 지문이 없는 오래된 기록은, Hermes CLI가 키 순서를 바꾸며 이 한 줄을 넣으면 여전히 충돌일 수 있습니다. 현재 writer는 semantic 지문을 항상 저장합니다. 키 순서를 바꾼 수용 테스트는 그 지문이 있는 경우만 통과합니다.

너의 추천

이 PR은 유지하면 됩니다. base는 dev이고, 같은 수정의 열린 PR은 #5711뿐입니다.

초안으로 두면 됩니다. 전체 테스트 결과를 본문에 적은 뒤 머지를 보면 됩니다. 방향은 #5710과 같습니다. 새 설치에는 헤더를 넣고, 기존 설치는 Apply로만 올리고, 다른 수정은 충돌로 두는 경계를 테스트가 잡고 있습니다.

Correct the Turkish Hermes writer guidance.

For existing Hermes configuration files, the writer patches only the managed providers.opencodex range. The Turkish guide incorrectly lists Hermes among whole-document writers and omits it from the source-preserving list. This contradicts the Hermes Apply paragraph and the canonical English guidance.
