Problem

  1. False fail-closed on real PRs. strix_report_scope.py (fix(strix): reject unscoped successful PR reports #2474) accepts a Strix report only if it contains a changed file's literal repository path. fix(strix): resolve evidence binder from trusted source #2291's hosted Strix run (job 109156573196) produced a completed report whose scope was /workspace/strix-pr-scope.…/scripts/ci/ and which reviewed strix_quick_gate.sh by name. The gate rejected it ("scan report does not identify a changed source file"), so the required strix check failed on a correctly scoped scan.
  2. Repository gates. The helper was exercised only through subprocess.run, so the fail-under-100 coverage gate measured it at 0%, and validate() had no docstring for interrogate.

Change

  • names_changed_path(): a changed path is identified when the report contains the full path, or when the file name appears as a standalone token and the report names its directory (scripts/ci/) or any ancestor of at least two segments (crates/mlsirm-core). Single-segment ancestors such as crates are too generic and do not count. Prefixed/suffixed names (my_strix_quick_gate.sh, strix_quick_gate.sh.bak), a bare name without its directory, and a wrong directory stay rejected. A sentence-ending period is allowed. Root-level files still require the exact name.
  • Residual looseness (deliberate). The directory test is a substring check, so other/scripts/ci/ also satisfies scripts/ci/, and a same-named file elsewhere could pass if the changed directory is mentioned anywhere in the report. The rule is calibrated to the replayed real report and is not a path parser; the guard's purpose stays "reject reports that name no changed source", not "prove the model's prose is correct".
  • The fix(opencode): extract coverage VCS import-root resolver (#2157) #2238 guard is unchanged: a report naming no changed file (the unrelated "OpenSSH RCE" report) is still rejected, as are incomplete or linked reports.
  • In-process tests cover every branch and both CLI outcomes. The original subprocess contract stays. validate() has a docstring.

Commits: RED test(strix): require directory-scoped file names… → GREEN fix(strix): accept changed files named within their reported directory.

Evidence (local, Python 3.14, CI hash lock)

Union evidence for the repository gates is in the PR comment (#2461, #2447, #2441, #2459, #2496, and this PR together reach 100% coverage and docstrings).

Summary by CodeRabbit

  • 버그 수정
    • 보고서에서 변경 파일의 전체 경로, 경계가 맞는 파일명, 파일 디렉터리 또는 상위 디렉터리를 식별해 변경 범위를 올바르게 검증합니다. 파일명의 일부만 일치하거나 다른 경로를 가리키는 경우에는 변경 파일로 잘못 판단하지 않습니다. 일치하는 변경 파일이 없으면 기존 오류를 표시합니다.
  • 테스트
    • 보고서의 변경 파일 식별과 범위 검증, 완료 여부 및 메타데이터 확인, 스캔 결과 개수, 출력 경로 유효성을 검사하는 테스트를 추가했습니다. 명령줄 실행 결과와 잘못된 입력에 대한 오류 출력도 확인합니다.

The report-scope helper from #2474 was exercised only through subprocesses,
so the repository coverage gate measured it at 0%, and validate() had no
docstring for the interrogate gate. Add in-process cases for every
fail-closed branch and both CLI outcomes; the subprocess contract stays.

📝 Walkthrough

Walkthrough

보고서가 변경 경로 전체를 포함하지 않아도 디렉터리와 경계에 맞는 파일명을 함께 지정하면 해당 변경 파일을 식별한 것으로 처리합니다. 테스트는 경로 판별, 범위 검증 및 CLI 동작을 확인합니다.

Changes

보고서 범위 검증

Layer / File(s) Summary
변경 파일 식별
scripts/ci/strix_report_scope.py
names_changed_path를 추가했습니다. 전체 경로가 없으면 디렉터리와 경계에 맞는 파일명이 함께 있는지 판정합니다. validate는 이 함수를 사용해 변경 파일 식별 여부를 확인합니다.
범위 검증 테스트
tests/test_strix_report_scope.py
메타데이터, 출력 경로와 심볼릭 링크, 스캔 개수 및 CLI 동작을 검증하는 테스트를 추가했습니다. 디렉터리와 파일명을 함께 지정한 보고서는 허용하고, 부분 파일명이나 일치하지 않는 디렉터리는 거부하는지 확인합니다.

Review details

Systems and components

  • observed — scripts (service) was modified; 1 changed file maps to changed impact.
  • observed — tests (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in tests/test_strix_report_scope.py: The test module adds imports for runpy, pytest, and strix_report_scope while retaining the existing subprocess, system, and path imports.
  • observed — Modified behavior in tests/test_strix_report_scope.py: Adds shared changed-source and completed-scan fixtures, a helper to write scan metadata and report files, and a test that accepts one completed report naming the changed source.
  • observed — Modified behavior in tests/test_strix_report_scope.py: Adds parameterized rejection tests for non-object metadata, invalid scan results, incomplete scans, and reports that do not identify a changed source.
  • observed — Modified behavior in tests/test_strix_report_scope.py: Adds checks that validation rejects missing or symlinked output directories and requires exactly one current scan report.

With the union's own CI hash locks on Python 3.14: full suite 5,156 passed, 4 skipped, 40 subtests; coverage report --fail-under=100 PASS (17,939/17,939 statements, 7,396/7,396 branches); interrogate scripts/ci 100%. On main alone the same gate is 99% (7 files) and interrogate 98.2%; a Linux python:3.14 container reproduced the identical miss set. This PR supplies the only piece no other open PR owned (strix_report_scope.py).

…source

#2291's hosted Strix report named its scope as scripts/ci/ and the changed
file as strix_quick_gate.sh, yet the report-scope gate demanded the literal
repository path and failed closed. Pin that shape as accepted while bare,
prefixed, suffixed, and wrong-directory names stay rejected.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A report that names the scanned directory and each changed file by name
now identifies that changed source. The file name must be a standalone
token, so prefixed or suffixed names do not match, and a bare name without
its directory is still rejected. The #2238 unscoped-report guard is
unchanged. Replaying #2291's hosted report: old gate rejects, new accepts.

파일명 뒤의 경로 구분자를 거부하도록 판정을 수정하세요.

현재 two_tier_recursion.rs/notes에서 _token("two_tier_recursion.rs")가 일치합니다. /가 후속 문자 금지 조건에 없기 때문입니다. 따라서 names_changed_path는 True를 반환하고, scope.validate는 이 테스트에서 예외를 발생시키지 않습니다.

파일명 매칭에는 /를 허용하지 않는 토큰 규칙을 사용하세요. 디렉터리 조상의 하위 경로 매칭은 기존 동작을 유지해야 합니다.
