fix(coverage): disclose Rust coverage timeouts as not measured - #2529
Conversation
fast-mlsirm's Rust suite outlasts the 900 s per-command cap under llvm-cov, so every Rust-changing PR failed coverage evidence on the timeout alone. For the Rust coverage commands only, exit 124 is reported as NOT MEASURED and listed in the Coverage Decision; test failures, thresholds and kills still fail.

… collection The 68% figure cited for .github#2524 was the advisory interrogate docstring result, not a gate; the gate failed on the configured pytest suite's _core ImportError.

Merge Risk: 🟡 Moderate · up to A timeout in the Tauri frontend preparation step can go unrecorded as a failure, and a Rust coverage timeout can still be reported as passing tests. Both weaken the coverage gate's reporting. Narrow the timeout flag to the two cargo llvm-cov calls and qualify the test-evidence line before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Timeouts are disclosed, but incomplete runs can still be described as passing test suites. The exception also covers frontend preparation commands beyond its intended scope. Existing isolation and ordinary failure checks limit the risk, but the evidence used for approval becomes less reliable. Retained concerns

시간 초과 허용 범위를 cargo llvm-cov 호출로 제한하세요.
현재 플래그가 설정된 상태에서 ensure_tauri_frontend_dist가 실행됩니다. 따라서 의존성 설치 또는 프런트엔드 빌드가 종료 코드 124를 반환해도 record_command_result가 실패로 집계하지 않습니다.
시간 초과 후 frontendDist가 생성되면 후속 디렉터리 검사가 성공하고 Rust coverage가 계속 실행됩니다. frontendDist가 없으면 별도의 실패 집계가 발생하지만, 시간 초과 자체는 여전히 실패로 기록되지 않습니다.
플래그를 두 cargo llvm-cov 호출 직전에 설정하고 호출 후 해제하세요.

Why
The workspace test suite of fast-mlsirm's Rust core, mlsirm-core, runs for tens of minutes under
cargo llvm-cov:--release, still not finished when stopped.That's far past the sandbox's 900 s per-command cap. So even after .github#2524, every Rust-changing fast-mlsirm PR fails coverage-evidence on the timeout alone, 7 of the 9 late-life stage-B PRs included. This follows the direction the coordinator proposed earlier: report a timeout as "coverage not measured" rather than a failure, and record it in the review.
