test: isolate Santiago timezone state and prove child completion

[lidge-jun]

Summary

Extract only the Santiago timezone fixture from #3950. Run its existing skipped-midnight, final-day activity and tooltip assertions in a bounded child process instead of mutating the shared test process timezone.

The parent preserves both TZ presence/value and its effective local timestamp. The child uses an explicit dashboard working directory and marker, validates its timezone, and emits a completion marker after the last assertion. The parent requires that marker plus successful exit/signal/deadline checks. Child test, child process and parent test deadlines are 10, 12 and 15 seconds respectively.

Source commit 1d8f6ff by @luvs01, with a focused test-integrity follow-up. Only the existing test file changes; no rendered UI, date interpretation, JWT, dependency or workflow change. B's JWT correction is separately landed in #3962; #3950 stays open until this independent part is also verified and landed.

Verification

• Independent planning/source audit confirmed the isolated scope and preserved original assertions. Final source review is recorded separately.
• Local product tests, builds, typechecks and installations: NOT RUN per owner instruction. Git diff checks passed.
• Existing current-head hosted PR CI is required. Supplementary evidence runs the exact candidate on Linux, macOS and Windows with the pinned Bun version, explicit TZ variants, child failure/marker/deadline controls and byte restoration. The verification-only workflow is excluded from this PR and will not be merged.
• Test-only change: no product screen changed and no fabricated UI screenshot is supplied.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed; product behavior is unchanged.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

📝 Walkthrough

Walkthrough

The Santiago midnight DST test now runs timezone-sensitive assertions in a spawned Bun child process. The parent process verifies child completion and preserves its timezone and clock state.

Changes

Usage custom-range DST isolation

Layer / File(s)	Summary
Child-process DST validation gui/tests/usage-custom-range.test.tsx	The test resolves the child working directory, spawns Bun with Santiago timezone settings, validates the custom-range report and heatmap tooltip, checks the completion marker and exit status, and verifies that the parent timezone and clock remain unchanged.

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

Merge Risk: ⚪ Minimal · up to ce71d

This change makes the Santiago DST test independent of the shared test-process timezone without changing product behavior. The child path verifies the rendered usage result and completion, with no remaining merge-blocking risk.

Supplemental verification is running at https://github.com/lidge-jun/opencodex/actions/runs/34169915911 . Evidence workflow commit f7b4ee6 checks out immutable delivery candidate 8223788 into a separate directory. The evidence workflow is not part of this PR and will not be merged; normal PR CI remains unchanged and required.

Independent security/verification-artifact review: PASS after strengthening negative-result attribution. It uses GitHub-hosted Linux, Windows and macOS, existing full-SHA-pinned actions, contents:read only, no secrets, persist-credentials:false, Bun1.4.0 and frozen dependency installs on those runners. The script requires actual target-test execution, case-specific failure diagnostics, child termination evidence and restored candidate bytes/HEAD. No local product commands were executed. A successful dispatch is not a passing test result; final logs and all platform conclusions will be inspected.

리뷰 · 우선순위 56 / 80

이 PR은 제품 화면이나 JWT·의존성을 바꾸는 게 아니라, GUI Usage 커스텀 구간 테스트 파일 하나(gui/tests/usage-custom-range.test.tsx)만 손봅니다. 지금 dev HEAD(9c8f66b9d, #3960 릴리즈 노트 enforcement 마커 정리 직후)에는 산티아고 DST 케이스가 같은 테스트 프로세스 안에서 process.env.TZ를 America/Santiago로 바꿨다가 되돌리는 방식입니다. 본문도 말했듯 Windows에서 “원래 TZ가 없었음”을 되돌리면 Bun의 실제 로컬 시각이 어긋날 수 있어서, 같은 파일의 다른 시계 의존 테스트까지 오염될 위험이 있습니다.

이번 변경은 #3950에서 산티아고 조각만 떼어 온 것입니다. 부모 테스트는 TZ가 이미 산티아고가 아니고 자식 플래그도 없을 때, Bun.spawnSync로 같은 파일을 필터(-t)로 다시 돌리되 자식 환경에만 TZ=America/Santiago와 OCX_USAGE_SANTIAGO_CHILD=1을 넣습니다. 자식이 기존 단언(자정 DST 시각, 마지막 날 활동 셀, 툴팁 날짜·토큰)을 그대로 한 뒤 OCX_SANTIAGO_CASE_COMPLETED를 stdout에 찍고, 부모는 그 한 줄과 exit/timeout/signal을 검사한 다음 자신의 TZ 존재 여부·값과 고정 로컬 시각이 그대로인지까지 확인합니다. 자식 10초 / spawn 12초 / 부모 15초로 경계를 맞춘 점도 읽힙니다. B트랙 JWT 쪽은 이미 #3962로 들어갔고, #3950은 이 조각이 따로 검증·랜딩될 때까지 열어 둔다는 설명과도 맞습니다. 현재 PR은 draft이고 Cross-platform CI는 아직 대부분 pending입니다. 제품 경로(src/·GUI 런타임)는 안 건드린 테스트 무결성 슬라이스라, 초록만 확인되면 dev에 넣기 좋은 편입니다.

라인 157~181 근처(현 HEAD 인프로세스 TZ 뮤테이션) - 이 PR이 없애려는 바로 그 패턴이다. 부모 프로세스 시계를 건드리지 않는 쪽으로 바꾸는 방향은 맞다.

gui/tests/usage-custom-range.test.tsx 가드 OCX_USAGE_SANTIAGO_CHILD !== "1" && TZ !== America/Santiago - 부모가 이미 TZ=America/Santiago이면 spawn 없이 본문을 그대로 돈다. 그 경우에도 완료 마커는 자식 플래그가 있을 때만 찍히므로, CI가 전역으로 산티아고 TZ를 준다면 부모 경로의 “완료 마커 필수” 검사를 건너뛰고 인프로세스만 통과할 수 있다. 의도인지 한 번만 확인하면 좋다.

Bun.spawnSync([... process.execPath, "test", import.meta.path, "-t", ...], { cwd: gui, timeout: 12000 }) - 테스트 안에서 같은 스위트를 중첩 실행한다. 샤드·부하 높은 macOS/Windows 잡에서 12~15초가 빡셀 수 있다. 실패 시 diagnostics에 stdout/stderr를 붙인 건 좋지만, CI에서 timeout이 반복되면 여유만 조금 늘리는 게 낫다.

완료 마커 console.log("OCX_SANTIAGO_CASE_COMPLETED") - bun test 출력 줄 단위 toContain으로 검사한다. 단언 실패 전에 찍히지 않으니 “초록 통과 증명”으로는 괜찮다. 다만 마커가 stderr로만 나가거나 리포터가 줄을 합치면 깨질 수 있어, 가능하면 stdout 한 줄 계약을 테스트 주석에 짧게 남겨 두면 유지보수가 쉽다.

enforce-target 잡이 fail로 보이는데 로그 blob은 이미 사라졌다 - draft/mergeable_state: blocked와 겹친다. ready for review 전환 후 게이트가 다시 도는지 확인이 필요하다.

메인테이너의 판단이 필요한 지점

• draft를 언제 ready로 올릴지, Cross-platform(특히 Windows·macOS 샤드)에서 중첩 bun test 타임아웃이 한 번이라도 나는지
• test: stabilize clock-dependent auth and usage fixtures #3950 전체 중 산티아고만 이 PR로 빼는 전략을 유지할지, 이 PR 머지 후 test: stabilize clock-dependent auth and usage fixtures #3950 본문/체크리스트에 “Santiago 조각은 #3967로 랜딩”을 명시하고 남은 조각만 남길지
• CI가 실수로 TZ=America/Santiago인 러너에서 부모 가드가 spawn을 건너뛰는 동작을 허용할지, 아니면 자식 플래그 경로만 강제할지

너의 추천
CI(특히 test/windows·macos 샤드) 초록과 draft → ready 전환을 기다린 뒤 squash 머지. 머지 직후 #3950에 Landed Santiago isolation via #3967 at <commit> 성격의 한 줄과, 남은 #3950 범위가 뭔지 짧게 남긴다. 타임아웃이 한 번이라도 나면 spawn/부모 deadline만 소폭 상향하고 제품 코드는 건드리지 말 것.

Final candidate is ce71d91 after accepting the sole-child-marker guard. Independent one-line source re-audit passed. The previously completed Linux/Windows proof on8223788bd remains historical; it does not certify the final head.

Supplemental final run: https://github.com/lidge-jun/opencodex/actions/runs/34170111719 . Evidence workflow SHA7d5f1097ec587a0ced441f475eb02d750e06b9ac differs from the previously security-reviewed evidence workflow only by its two immutable candidate-SHA literals. The Python script and permissions/actions/commands are unchanged. Normal final-head PR CI is34170093095. Both runs must complete, with actual per-platform cases and restored candidate bytes inspected. No local product checks or dependency installs were run.

[lidge-jun]

Maintainer screenshot waiver: this PR changes only gui/tests/usage-custom-range.test.tsx and no product UI, layout or rendered content. There is no changed product screen to capture. Applying the repository’s existing gui-screenshot-waived exception for this verified test-only scope; hosted execution and independent test review remain mandatory and are not waived.

[lidge-jun]

Final supplementary proof succeeded: run34170111719, evidence workflow7d5f1097e, immutable candidatece71d9171. Linux, Windows and macOS each passed all10 scenarios: five positive/restored runs and five deliberately failing controls with exact target diagnostics. Every platform verified candidate file SHA-256, restored bytes/HEAD and timeout-child termination. Normal current-head PR CI34170093095 remains required and is still running; no local product tests/builds/installs/typechecks were executed.

[lidge-jun]

Normal CI34170093095 attempt1 did not complete: macOS1 job101889247755 reached the20-minute job limit. Its last pass was the unchanged client-connect CLI rejection test, followed by a dangling-process cleanup message. No assertion failure or completed suite was emitted.

Independent investigation verified that the changed dashboard test is not discovered by this root macOS lane, and the client test/helpers/configuration/dependencies are unchanged. The next declared client scenario uses an unbounded node:child_process.spawnSync; this is a containment gap, not proof of where the process hung. The same helper passed in the earlier release-note CI on the same Bun/runtime image, but that is not reproduction of this failure on an untouched baseline. Root cause remains unknown.

A single same-head failed-job diagnostic rerun is in progress. Its result will be recorded separately; a green rerun does not establish that the client-test hang was fixed. No unrelated test or timeout policy was changed. The final candidate's supplemental Linux/Windows/macOS timezone proof remains independently successful at run34170111719.
