Summary

  • Centralize temporary port-probe resource cleanup in its existing owner.
  • Preserve bind-error handling, retry deadlines, pinned/reserved-port policy,
    and all nine existing exports. No live-service or configuration changes.
  • Add two subprocess-isolated lifetime regressions while retaining all eleven
    original port tests; document ownership in the Runtime structure map.

Independent verification prerequisite WP445; not a modularization ledger-row
completion. The status extraction remains a separate child PR.

Verification

  • Focused regression and negative-control evidence is retained in ignored
    scratch; no reproduction instructions are included in public working notes.
  • Independent static source/test/resource-lifetime review: PASS at
    d2b4a81 (including subsequent documentation review).
  • Corrected port tests:13pass/0fail; independent control review passed.
  • Isolated exact-head remote Bun1.4.0: bun run typecheck passed;
    focused ports/reclaim/update/core-Lab-boundary70pass/0fail; privacy passed;
    bun run test 18,775pass/16skip/0fail. Dependency/build setup also passed.
  • Receipt exit0 at the named head with clean checkout before/after SSH.
  • Hosted CI33954745415 passed at the named final head. Both documentation
    review findings are addressed and resolved; final-head remote gates also passed.
  • No local tests, suites or typecheck ran. No merges, releases or live service
    changes were performed by this repair.

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.

📝 Walkthrough

Walkthrough

The change adds planning rules for a 68-file split train and fixes temporary TCP probe servers. Both port-selection paths now destroy accepted connections before closing. Child-process tests verify disposal and close completion.

Changes

Split-train governance

Layer / File(s) Summary
Split-train rules and verification controls
devlog/_plan/260905_now_split_train/000_plan.md, devlog/_plan/260905_now_split_train/003_parent_decisions.md
The plan defines pure-move limits, residual handling, layer dependencies, branch ownership, isolated verification, and terminal accounting. It records the 68-file objective and 77 implementation layers.

Probe connection disposal

Layer / File(s) Summary
Probe connection disposal
devlog/_plan/260905_now_split_train/445_server_port_probe_disposal.md, src/server/ports.ts, structure/01_runtime.md
createProbeServer() destroys accepted sockets and handles socket errors. isPortAvailable and allocateEphemeralPort use the helper. Runtime ownership documentation records the lifecycle contract.

Isolated probe regression coverage

Layer / File(s) Summary
Isolated probe regression coverage
tests/server/ports.test.ts
The child-process harness verifies peer disposal and delayed close completion. Parameterized tests cover isPortAvailable and findAvailablePort.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to d2b4a

Temporary port probes now dispose accepted TCP peers so listener closure is not delayed by connected readiness clients. The documented behavior and regression coverage indicate no remaining merge-blocking risk.

이 PR은 src/server/ports.ts 안의 짧은 포트 프로브가, 잠깐 붙잡은 TCP 피어 때문에 server.close()가 끝나지 않는 문제를 고칩니다. 지금은 isPortAvailableallocateEphemeralPort가 둘 다 그냥 createServer()만 만들고, 연결이 들어와도 소켓을 바로 버리지 않습니다. 그래서 readiness 클라이언트가 프로브에 붙으면 리스너 close 대기가 길어지고, 기동·복구·CI 타임아웃처럼 보일 수 있습니다. 현재 dev HEAD 6b85485f3는 Windows cold restore/inject 수명(#3637)과 native fixture(#3629) 쪽을 막 닫은 상태이고, 패키지는 아직 2.43.0입니다. 이 변경은 그 스택과 겹치지 않는 서버 포트 선택 경로 수리이며, 본문대로 WP450 상태 분리(#3633) 전에 깔아 두는 WP445 전제입니다. 코드 본체는 비공개 createProbeServer 한 곳(+공개 connection 리스너로 즉시 destroy)으로 두 호출부를 바꾸고, 기존 바인드 에러·재시도·예약 포트·아홉 개 export는 그대로 둡니다. 회귀는 부모 프로세스의 Server.prototype을 건드리지 않고, 자식 --eval 안에서만 listen/close/address를 가로채서 피어 dispose와 close 완료 순서를 검사합니다. Bun이 생성자 콜백 등록을 accept 직전까지 미루는 점을 근거로 생성자 콜백 대신 server.on("connection")을 listen 전에 다는 선택도 문서에 남아 있습니다.

라인 약 4–11 (src/server/ports.ts createProbeServer) - 설계 자체는 맞지만, destroy 직후 socket.on("error", …)만 달아 둔 형태라 실제 destroy 경로에서 에러가 이미 났을 때의 중복 destroy 비용은 작아도, 리뷰어가 “에러 핸들러가 정말 필요한가”를 한 번 더 물어보게 됩니다. 테스트가 그 경로를 강제하니 유지 쪽이면 한 줄 주석으로 의도를 고정하는 편이 낫습니다.
경로 devlog/_plan/260905_now_split_train/000_plan.md · 003_parent_decisions.md - 이번 버그픽스 본체와 직접 관련 없는 68파일 스플릿 트레인 전체 계획/부모 결정서가 같이 들어왔습니다. 445 문서만으로도 WP445 근거는 충분해서, 이 PR의 “focused repair” 주장과 문서 덩어리가 어긋납니다.
경로 CI (test 1–4/4, macos shards) - 초반 게이트·keyring·npm-global은 통과했지만 본 테스트 샤드가 아직 pending입니다. draft인데 원격 Bun 증거만으로 merge 준비라고 읽히면 위험합니다.
경로 tests/server/ports.test.ts 자식 픽스처 - prototype override가 자식으로만 격리된 점은 좋습니다. 다만 findAvailablePort(0) 경로는 내부 allocateEphemeralPort까지 가는지 assertion이 43219 고정값에 의존하므로, 나중에 allocator 주입 경로가 바뀌면 거짓 초록이 날 수 있습니다.
경로 스택 #3633 - 본문이 “이 수리 후 restack”이라고 적었는데, #3633은 이미 dev 베이스로 열려 있습니다. 머지 순서와 restack 주체를 이 댓글만으로는 한 번에 확정하기 어렵습니다.

메인테이너의 판단이 필요한 지점

  • 000/003 전체 계획 문서를 이 버그픽스 PR에 남길지, docs 전용 브랜치로 빼서 445+코드+테스트+structure 행만 남길지
  • draft를 유지한 채 hosted CI 풀그린을 기다릴지, CI 완료 직후 ready+merge로 올릴지
  • refactor(cli): isolate status health and stale-process probes (S14 1/3) #3633(WP450) restack을 이 PR 머지 직후 필수 후속으로 묶을지, 아니면 #3633이 이미 독립 dev 베이스라서 병렬 유지할지
  • 이 수리를 “과거 CI startup timeout의 원인 확정”으로 커뮤니케이션할지, 본문처럼 “재현된 소켓 수명 결함 수정”으로만 한정할지

너의 추천
호스티드 CI 테스트 샤드가 전부 초록이 되면 draft를 풀고 dev에 먼저 머지하세요. 코드+테스트 범위는 작고 현재 dev 방향과도 충돌이 없습니다. 000/003은 가능하면 이 PR에서 빼거나 follow-up docs PR로 분리하고, 머지 뒤에는 #3633을 새 HEAD에 restack·재검증하세요. types.ts/config.ts 스플릿 캠페인에 무효화되는 변경은 아닙니다.
