📝 Walkthrough

Walkthrough

CI 메타데이터 스크립트의 네 개 subprocess.run 호출에 shell=False를 명시했습니다. 관련 보안 지침을 .jules/sentinel.md에 기록했습니다.

Changes

subprocess 보안 설정

Layer / File(s)	Summary
subprocess 호출과 보안 지침 업데이트 scripts/ci/reconcile_repository_metadata.py, .jules/sentinel.md	_gh_api, _pages_exists, _repository_file_exists, _deepwiki_badge_exists의 subprocess.run 호출에 shell=False를 추가했습니다. 동일한 설정을 요구하는 보안 지침을 기록했습니다.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 8a661

The CI metadata script retains its existing behavior while making safe subprocess execution explicit. No merge-blocking risk remains.

Pull request overview

OpenCode could not approve from deterministic current-head evidence because GitHub Checks have failed.

Findings

1. HIGH Current-head GitHub Checks - Fix failed required checks before approval

• Problem: Failed same-head checks remain for 8a6613b548ef727cd6752d8003227fc9114ce5b9.
• Root cause: The model-unavailable evidence fallback is allowed only when peer GitHub Checks are complete and clean.
• Fix: Read and fix the failed check logs below, then rerun the current-head checks.
• Regression test: Keep the model-unavailable fallback gated on an empty failed-check rollup.

Failed checks:

• CodeQL PR/CodeQL compatibility analysis (actions): FAILURE (https://github.com/ContextualWisdomLab/.github/actions/runs/34538681852/job/103093549874)
• CodeQL compatibility analysis (actions) check run: failure (https://github.com/ContextualWisdomLab/.github/actions/runs/34538681852/job/103093549874)
• Required Noema Review/noema-review: FAILURE (https://github.com/ContextualWisdomLab/.github/actions/runs/34538681832/job/103078817996)

Exact-head admission audit: 8a6613b548ef727cd6752d8003227fc9114ce5b9 (base main@cb0872c9a20d5584703dffacca65c096fc034c6c, 1 ahead / 0 behind).

현재 blocker: mechanically non-mergeable; 활성 CHANGES_REQUESTED 1건.

유효 commit·diff·review evidence를 보존한 채 Draft/Proposed로 교정합니다. Base 이동이나 queue 대기만을 이유로 Close하지 않으며, Force Push·synthetic status/approval·manual rerun·bypass는 사용하지 않습니다. Blocker 수리 후 새 exact head에서 Checks와 review admission을 다시 받아야 합니다.

Acknowledged. I will stop work on this task, as the PR is currently marked as mechanically non-mergeable due to an active CHANGES_REQUESTED status. I will not close the PR or force push, but rather await further review admission.

Closing as a duplicate of the semantic no-op already decided in #1390 (and #2129): subprocess.run/Popen default to shell=False, and _probe_isolation_capability passes an argv list, so adding the keyword changes no behavior or security boundary. start_service/run_shell on main already pass shell=False explicitly. Branch and commits remain recoverable; reopen if a reproduced shell-execution path is found.

Understood. Acknowledging that this work is now obsolete and stopping work on this task. This PR is being closed as a duplicate because subprocess.run already defaults to shell=False and the current explicitly identified functions are using argv lists.
