Verdict: The tier1 tests FAIL (pnpm -r run test) is an infrastructure flake, not a code regression. Correct handling is retry gitreins judge
I've diagnosed the issue and written a verified, self-contained runbook. I reproduced the core mechanic (a 500-byte capture cap on a SIGTERM'd pnpm -r run) and validated the detection procedure against mock GitReins verdicts. Solution saved to ~/SOLUTION.md.
Verdict: The tier1 tests FAIL (pnpm -r run test) is an infrastructure flake, not a code regression. Correct handling is retry gitreins judge <id> once, preserve both runs, record every run id, and stop. Do not treat the truncated output as test evidence and do not chase the full suite locally.

If all five hold, the runner killed the process before Vitest could print its final reporter summary. The 500-byte boundary is the runner's capture cap, not a test result.
pnpm -r run test runs the workspace serially: packages/shared → apps/api → apps/web. Full-suite wall time is minutes; under concurrent load (other guards, the tier2 evaluator, shared bunker contention) it exceeds the guard's time budget.packages/shared always shows green because it runs first (before the kill) and its 34 tests are fast; truncation lands during apps/api, before apps/web starts.801a9b1a PASS) and had already failed once in the same shape (92f03b2f FAIL). A deterministic regression cannot alternate PASS/FAIL on an unchanged tree.50.0 M cap / 50.1 M used, yet tier2 still COMPLETED. Per corpus answer 2269, the input-cap raise applies to INCOMPLETE verdicts only. COMPLETED tier2 makes the warning informational — take no action.
There is no code fix. The fix is the correct GitReins triage + preserve-and-retry procedure, plus durable guard-budget hardening if the flake recurs.
