Summary

When ocx stop cannot create a teardown receipt, the proxy performs shared Codex/Grok restoration itself. An HTTP 200 response containing { success: false, sharedTeardown: "performed" }, followed by process exit, currently counts as graceful success. The parent then skips restoration even though the proxy reported that it failed.

Require success: true and the assigned teardown mode (performed, or deferred when a receipt nonce was sent) before reporting graceful completion. An exited process with an unconfirmed response gets a separate internal result: stopProxy avoids its forced-stop fallback and returns false so the existing parent restoration path runs. Ownership refusals still throw before restoration or receipt discharge; a confirmed deferral still leaves final restoration and receipt handling with the parent.

This confirms the shared-teardown response plus observed exit. It does not attest the proxy's exit code or completion of every drain hook. Unreadable or older responses conservatively retain parent restoration. English and Korean lifecycle docs describe that behavior.

Verification

  • Current head 7dc24054614c9454d27dbe0a619ec4a691958f66, based on dev 8026405d9a527085b3c972dc8630abf8fe3b0441; Windows, Bun 1.4.2, frozen dependency lockfile.
  • Before the fix, the new response/parent regression set produced 11 failures across the two focused files. A separate parent-path control reproduced skipped Codex/Grok restoration after receipt creation failed and the child reported failure. These pre-fix runs used Bun 1.4.0 before the upstream runtime bump.
  • On the current head, bun run test -- --timeout 60000 --parallel=1 tests/lib/process-control-graceful.test.ts tests/service/stop-deferred-teardown.test.ts tests/cli/cli-management-auth.test.ts tests/providers/xai/grok-lifecycle.test.ts tests/service/service-stop-verification.test.ts tests/lib/process-control.test.ts passed 104 tests / 476 assertions. Each parent fixture runs the real CLI entry point, parser, dispatcher, stop module, and receipt implementation in a bounded child process. Only process/client/HTTP I/O and unrelated shim preflight are mocked there; the tests inspect the actual exit code, stderr, and temporary receipt files. Coverage includes failed/unreadable/mismatched responses, observed exit, no forced kill, actual parent restoration calls, failed restoration retaining its receipt, successful deferral, history-only failure, and the server's 409 reason reaching CLI stderr. No source slicing or dynamic function reconstruction remains.
  • Two independent negative controls were detected: treating an unconfirmed response as success skipped parent restoration, and dropping the module's refusal message lost the server's remediation text. The runtime file was restored byte-for-byte before the final passing run.
  • bun run typecheck, bun run privacy:scan, and git diff --check passed. Independent read-only reviews of the runtime change and isolated CLI fixture found no required corrections.
  • Documentation build passed: 425 pages, 32.79 seconds. Those documentation files are unchanged in the fixture follow-up. Current-head full contributor CI is running. The previous-head run was superseded and cancelled by the new run after the test fixture changed; it is not reported as full-green evidence. This PR remains a draft until full CI and review are complete.

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 checklist

  • All CI tests are green on my local testing.
  • I pushed my PR to the latest dev commit.
  • I resolved all correct Codex and CodeRabbit findings.
  • My PR is ready for review.

📝 Walkthrough

Walkthrough

stopProxyGracefully now requires explicit shared-teardown confirmation and observed process exit. Unconfirmed teardown returns a distinct result, so stopProxy avoids forced termination and leaves restoration to the parent CLI. Tests and lifecycle documentation cover receipt handling and failure paths.

Changes

Shared teardown stop flow

Layer / File(s) Summary
Validate teardown confirmation
src/lib/process-control.ts
Adds the "teardown-unconfirmed" result. stopProxyGracefully validates success and the expected "performed" or "deferred" mode. stopProxy waits for the stopped port without entering forced-stop fallback.
Verify parent restoration behavior
tests/service/stop-deferred-teardown.test.ts, docs-site/src/content/docs/...
Runtime tests cover receipt-backed restoration, refusal handling, exit codes, endpoint requests, and incomplete receipts. English and Korean lifecycle documentation describes parent-owned restoration and cleanup.
Exercise response and ownership cases
tests/lib/process-control-graceful.test.ts, tests/cli/cli-management-auth.test.ts
Tests cover malformed, incomplete, deferred, unexpected, confirmed, and refused responses. Mock responses now include sharedTeardown.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to f2327

The stop flow now requires confirmed shared teardown before skipping parent restoration. The implementation coverage is broad, but the new runtime regression harness is fragile and does not fully validate refusal-state propagation, creating bounded maintenance and regression-detection risk.

리뷰 · 우선순위 74 / 80

이 PR은 ocx stop이 프록시를 “정상 종료”로 보고 부모 복원을 건너뛰는 구멍을 막는 수정입니다. 지금 dev HEAD는 8026405d9(#4067 wp7, 프록시 stop 거절 사유를 그대로 전달)이고 package는 2.49.0입니다. 서버 쪽 src/server/stop-teardown.tsperformStopTeardown는 이미 정직합니다. 네이티브 Codex 복원이나 Grok fence 정리가 실패하면 HTTP는 200이어도 JSON에 success: falsesharedTeardown: "performed"를 넣고, 프록시는 곧 프로세스를 끝냅니다. 그런데 HEAD의 stopProxyGracefully(src/lib/process-control.ts)는 200만 확인하고 본문을 읽지 않은 채 waitExit 결과만 돌려줍니다. 프로세스가 끝나면 true가 됩니다. 부모 CLI stopWithDeferral(src/cli/index.ts)는 “graceful && 영수증 없음”이면 자식이 이미 복원했다고 보고 부모 복원을 건너뜁니다. 영수증을 못 써서 자식이 직접 복원하기로 한 경로에서, 자식이 “복원 실패”를 보고해도 부모는 성공으로 읽고 Codex/Grok이 죽은 프록시를 가리킨 채로 남을 수 있습니다. 이 PR은 그 갈라짐을 닫습니다.

고치는 방식은 좁습니다. GracefulStopResult"teardown-unconfirmed"를 추가합니다. 200 응답 본문에서 success === true이고, 요청한 모드(deferred는 영수증 nonce가 있을 때, 아니면 performed)와 sharedTeardown가 같을 때만 true입니다. 프로세스는 나갔는데 본문이 실패·깨짐·모드 불일치면 "teardown-unconfirmed"입니다. stopProxy는 이 값을 받으면 강제 kill로 가지 않고 false를 돌려, 기존 부모 복원 경로가 다시 돕니다. 409 거절은 예전처럼 throw하고 복원·영수증 정리를 하지 않습니다. 문서(영/한 lifecycle)에도 “종료만으로 공유 복원 성공이 아니다”를 적었습니다. 테스트는 graceful 단위 + 부모 fixture(tests/service/stop-deferred-teardown.test.ts)로 실패 응답·확인된 performed·실패한 부모 복원·확인된 deferral·history-only·409를 돌립니다. types/config 분할에 무효화되는 범위가 아닙니다.

왜 우선순위가 높은가. stop/restore는 Windows Task Scheduler 리스폰과 #3008 영수증 계약의 핵심입니다. tip #4067이 방금 거절 메시지 정확도를 올렸고, 이 PR은 그 바로 옆 “성공으로 오인하는 200”을 고칩니다. 2.49.0 마감 열차에 넣을 만한 운영 정확도 버그입니다. head는 f2327ab35dev 8026405d9 위에 있고 draft입니다. hygiene/label/resolve/enforce-target·CodeRabbit은 통과했고, 본문은 전체 CI를 draft 해제 조건으로 적어 두었습니다.

라인 src/lib/process-control.ts GracefulStopResult - "teardown-unconfirmed" 추가. “거절(강제 금지)”과 “종료는 됐지만 복원 미확인(강제 금지·부모 복원)”을 나눈 점이 맞다.
라인 src/lib/process-control.ts stopProxyGracefully 본문 파싱 - success === true와 기대 sharedTeardown를 같이 본다. 구버전·깨진 JSON은 보수적으로 미확인 처리한다.
라인 src/lib/process-control.ts stopProxy - 미확인이면 kill 없이 false. 이미 나간 프로세스에 taskkill을 또 보내지 않는다.
라인 src/cli/index.ts stopWithDeferral(호출 계약) - 코드 변경은 없지만, graceful=false가 되면 부모 복원이 다시 돈다. 영수증 없는 실패 응답 경로가 이 계약에 정확히 걸린다.
라인 tests/service/stop-deferred-teardown.test.ts - 부모 fixture가 실제 stop 본문·임시 영수증·restore 호출 수를 본다. 회귀 재현에 충분하다.
경로 docs lifecycle(영/한) - 운영자 기대(“프로세스가 죽으면 복원도 됐다”)를 문서에서 깨 준다. 좋다.
경로 CI/draft - 전체 contributor CI·draft 해제가 남았다. 머지 전에 초록을 확인해야 한다.

메인테이너의 판단이 필요한 지점

  • draft를 유지한 채 전체 CI만 기다릴지, CI 초록 즉시 ready로 올려 2.49.0 tip에 붙일지
  • success: false이지만 프로세스가 나간 경우를 로그/doctor에 한 줄 더 남길지(지금은 부모 복원으로 조용히 복구)
  • #4067과 같은 stop 축이므로, 릴리즈 노트에 wp7(거절 사유) + 이 PR(공유 teardown 확인)을 한 묶음으로 적을지

너의 추천
CI 초록 확인 후 draft 해제하고 머지하세요. #4067 직후 stop 계약의 빈칸을 정확히 메우고, 범위·테스트·문서가 한 축이다. types/config 분할 close-don't-rebase 대상 아님. 머지 전 bun run test로 본문이 적은 graceful/deferred/stop 묶음만 한 번 더 확인하면 충분하다.
