test: isolate the route scanner probe in a unique temp directory

[luvs01]

Summary

• Move the management route scanner's negative probe out of the repository root and into a uniquely named OS temporary directory.
• Use static node:fs imports for fixture creation and cleanup.
• Remove the temporary directory recursively in finally while preserving the existing fail-loud scanner assertions.

The fixed .tmp-scanner-probe.ts path was shared by concurrent runs, so one run could remove another run's fixture. An interrupted run could also leave an untracked TypeScript file in the worktree. A per-run directory created with mkdtempSync removes the shared-path race and keeps interruption residue outside the repository.

This addresses the concurrency and residue concern raised in review feedback on #2826.

Verification

• bun test --isolate ./tests/management-route-registry.test.ts — 13 pass, 0 fail, 28 expect() calls on Bun 1.4.0 (34cbb9a40).
• git diff origin/dev..HEAD --check — clean.

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.

No documentation or release-note change is needed because this only changes test-fixture placement; runtime behavior and public interfaces are unchanged.

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

• 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.

Summary by CodeRabbit

• Tests
  • Scanner probe tests now use isolated temporary directories instead of repository-local paths.
  • Temporary probe files and directories are automatically removed after testing.
  • This keeps test artifacts contained and ensures the test environment is cleaned up consistently.

📝 Walkthrough

Walkthrough

The scanner probe test now creates its probe in a unique system temporary directory, writes it through imported filesystem utilities, and removes the directory recursively after execution.

Changes

Scanner probe test

Layer / File(s)	Summary
Temporary probe lifecycle tests/management-route-registry.test.ts	Lines 2–3 add static imports for temporary-directory creation, file writing, cleanup, and the system temporary path. Lines 126–127 use a unique temporary directory. Lines 138–144 write the probe and remove the directory recursively with force enabled.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 0facd

The scanner test now isolates its temporary probe and cleans it up reliably, preventing parallel-run fixture collisions without changing runtime behavior or public interfaces.

리뷰 · 우선순위 44 / 80

설명

이 PR은 management route scanner의 “방법(method)을 못 정하면 GET으로 짐작하지 말고 unresolved로 남겨라”는 음성 프로브 픽스처를, 저장소 루트의 고정 경로 .tmp-scanner-probe.ts에서 OS 임시 디렉터리의 유일 경로로 옮긴다. 지금 dev HEAD ff1ac6b8c의 tests/management-route-registry.test.ts는 여전히 join(repoRoot, ".tmp-scanner-probe.ts")에 쓰고 finally에서 파일만 지운다. 병렬로 같은 테스트가 돌면 한쪽이 다른 쪽 픽스처를 지울 수 있고, 중간에 죽으면 워크트리에 추적되지 않는 .ts 찌꺼기가 남는다. #2826 리뷰에서 나온 동시성·잔여물 지적에 대한 후속이다.

변경은 테스트 한 파일뿐이다. mkdtempSync(join(tmpdir(), "ocx-route-scanner-"))로 디렉터리를 만들고, 그 안에 scanner-probe.ts를 쓴 뒤, finally에서 rmSync(tempDir, { recursive: true, force: true })로 통째로 지운다. require("node:fs") 대신 정적 import를 쓴 것도 읽기 좋다. scanRoutes는 파일 경로만 받으므로 저장소 밖 경로여도 음성 프로브(unresolved method) 목적은 그대로다. 런타임·공개 API·types/config 분할과 무관하다.

제품 우선순위는 낮다. 다만 CI를 병렬로 돌리거나 로컬에서 테스트를 여러 번 겹치면 실제로 flake/잔여물 원인이 될 수 있는 자리라, 값이 없는 정리은 아니다.

tests/management-route-registry.test.ts 음성 프로브 - 루트 고정 .tmp-scanner-probe.ts 공유가 핵심 문제였고, per-run temp dir로 그 공유를 제거한 방향이 맞다.

tmpdir() + ocx-route-scanner- 접두사 - 이름만으로도 잔여물이 보이면 이 테스트 것임을 알 수 있다. recursive: true cleanup도 디렉터리 단위로 맞다.

프로브 소스의 dispatch(chosen) / req.method 패턴 - 이번 PR이 만든 것은 아니고 기존 음성 케이스다. 스캐너가 여전히 method를 null로 남기는지만 보면 된다. 경로 이동만으로 그 단언이 약해지지는 않는다.

메인테이너의 판단이 필요한 지점

• 테스트 전용 flake 가드를 지금 merge train에 squish 할지, 아니면 다음 test/chore 묶음에 태울지 (내용 자체는 막힐 이유가 없다)

너의 추천
머지해도 된다. 런타임 위험이 없고, #2826에서 남긴 동시성 구멍을 정확히 닫는다. 우선순위는 낮으니 Meta/릴리즈 열차 뒤에 가볍게 넣으면 된다.

This fix is still useful on current dev: the same repository-root probe remains at tests/server/management-route-registry.test.ts:126.

The PR is now conflicting because the test-layout migration moved tests/management-route-registry.test.ts into tests/server/. Please rebase onto current dev and reapply the same mkdtempSync plus finally cleanup change at the new path. Keep probe creation inside the protected try so cleanup also runs if the write fails, then rerun the focused test and exact-head CI. The runtime scope and value assessment are otherwise unchanged.
