test(orchestrator): stop service.test.ts from depending on real OS pids (hard-coded fake pids collide with live processes)

[hojinzs]

배경

packages/orchestrator/src/service.test.ts가 워커 프로세스를 하드코딩된 가짜 pid(4100, 4101, 4102, 4103, 4105, 4411 …)로 만들고, 서비스는 isRunProcessRunning → isProcessRunning(pid)로 실제 OS 프로세스 존재 여부를 확인합니다. 해당 pid를 가진 프로세스가 실행 중인 머신에서는 워커가 "살아 있음"으로 판정되어 다음 테스트가 환경 의존적으로 실패합니다:

• service.test.ts:1894 — 완료된 워커의 레코드가 retry_queued여야 하는데 running으로 남음
• service.test.ts:3667 — 위의 결과로 retry-scheduled verbose 로그 누락

2026-08-29 09:58Z 기준 이 머신에서 pid 4102가 살아 있는 node_repl 프로세스였고, 에이전트의 pnpm test 게이트가 #721/#732/#749 등 서로 무관한 이슈에서 반복 실패해 Backlog로 되돌아갔습니다(코드 리뷰 에이전트 4건도 동일 재현, main 기준). CI(GitHub 러너)는 pid 충돌이 없어 통과 — 로컬 전용 플레이크.

수정

• 테스트에서 실제 pid 대신 isProcessRunning/resolveProcessIdentity를 주입 가능하게(이미 vi.spyOn(service, "isRunProcessRunning") 패턴이 :517에 있음) 하거나, 가짜 pid를 확실히 존재하지 않는 값으로 생성(예: 자식 프로세스를 spawn 후 종료시켜 얻은 pid, 또는 process.pid와 무관한 2^22 이상의 범위는 macOS에서 무효이므로 사용 불가 — 주입 방식 권장).
• 동일 패턴을 쓰는 다른 테스트(dispatch.test.ts, recovery 관련)도 점검.
• changeset 불필요(테스트만).

완료 기준

• 가짜 pid와 같은 번호의 프로세스가 살아 있어도(테스트에서 isProcessRunning을 true로 스텁해 재현) 해당 테스트들이 결정적으로 통과.
• pnpm --filter @gh-symphony/orchestrator test 10회 연속 통과(이 머신).

관련: #721, #732, #749(에이전트 게이트 차단), #758(같은 부류의 테스트 결정성). Epic #651. 영향도: 상 (로컬 에이전트 파이프라인 전면 차단).

[hojinzs]

추가 증거 — 같은 머신에서 pid 4100–4105/4411이 모두 비어 있는 시점(10:0xZ)에 packages/orchestrator에서 npx vitest run src/service.test.ts → 193/193 통과. 즉 실패는 코드가 아니라 가짜 pid와 실제 프로세스의 충돌 여부에 따라 달라지는 환경 의존 플레이크입니다. 재현 시에는 isProcessRunning을 true로 스텁해 확인하세요.

Workpad — #762 — Cycle 2

Type: rework cycle (PR #766)
Branch: feat/762-isolate-service-test-pids
Draft PR: #766
Cycle opened: 2026-08-29T10:48:00Z · Trigger: Ready-return review rework for remaining host-PID-dependent tests

Status Transitions

• 2026-08-29T10:46:13Z · Ready → In progress · address requested deterministic PID-test coverage (cycle 2 open)
• 2026-08-29T20:26:00Z · In progress → In review · reviewed host-PID cases isolated and full validation passed (cycle 2 close)

Plan

• 1. Inject deterministic liveness probes into the two remaining reviewed service lifecycle tests, assert their PID calls, and reply to every review thread.
• 2. Wrap-up: re-verify the original issue · pass the Completion Bar · changeset (not required) · refresh PR · request re-review · transition to In review

Rework / PR Feedback

• Major merge blockers from review:
  • P1: continuation-restart test uses a host-dependent spawned PID.
  • P2: after-run-hook test uses a host-dependent persisted processId.
  • Scope decision: retain focused per-test injection; a test-suite-wide process-table shim is out of scope for test(orchestrator): stop service.test.ts from depending on real OS pids (hard-coded fake pids collide with live processes) #762.

• Changeset: N/A (test-only change; no release label).

Progress Log

• 2026-08-29T10:48:00Z: Read the requested review, all inline comments, and PR context; classified this as a rework cycle in the Execution layer. The change remains test scaffolding only and conforms to the upstream Symphony specification without divergence.
• 2026-08-29T11:00:45Z: Added focused false-liveness injection and PID assertions for the continuation-restart (4310) and after-run-hook persisted-process (999999) cases in commit 516f7a63; pushed and replied to every review thread.
• 2026-08-29T20:22:00Z: Revalidated the original issue criteria: the four identified host-PID paths use deterministic injected liveness probes; dispatch.test.ts was inspected and the full orchestrator suite covers it. The targeted service suite passed 10 consecutive runs and all repository validation gates passed. Prepared the In progress → In review transition body above.
