gitreins-tier1-guard-step-timeout-120s-default
Solution written to ~/gitreins-tier1-guard-step-timeout-solution.md.
I couldn't reach the private repo, but I downloaded the gitreins wheel (0.15.0) and confirmed the root cause directly in the engine source:
engine/pipeline.py _run_script_step():
timeout=step_def.get("timeout", 120), and on out["timed_out"] it returns error="Command timed out". Un-timed script steps die at 120s.guards.test_timeout is irrelevant — it is read only in tier1_plan() (test_timeout = int(guards_cfg.get("test_timeout", 120))) and applied only to the generated tests step (test_step["timeout"] = test_timeout), plus the guard's internal test check (default 180s). A hand-authored guard step is never touched by it.timeout: 3600 (suite + headroom) to the tier-1 guard step in .gitreins/config.yaml.I initially wrote a yaml.safe_load + safe_dump one-shot patch, then tested it and found it corrupts on: into true: (YAML 1.1 boolean-key pitfall). I replaced it with a line-based, idempotent patch and tested that it preserves on: [pre-commit, pre-eval] and inserts the key only when absent.
The document contains: root-cause analysis, the exact YAML before/after, a guarded text patch, a static check, an end-to-end verification (gitreins judge + grep for Command timed out), and the load-flake note about re-running at lower load before investigating the 10s beforeAll hook timeout.

{"description": "GitReins tier1 judge FAIL 'guard: Command timed out' is a STEP timeout, not the test rung: pipeline.py runs each script step with step_def.get('timeout', 120), and the default tier1 'guard' step definition carries no timeout key, so the guard (which itself runs the full test suite) is killed at 120s regardless of guards.test_timeout (that knob only sizes the INNER tests step). Signature: repeated tier1 'Command timed out' verdict-FAILs in a fixed ~2min wall window, while the same commit's battery passes standalone. Fix: add timeout: <suite+headroom> (e.g. 3600) to the tier1 guard step in .gitreins/config.yaml pipeline.stages; revert any blind guards.test_timeout raises. One retry may still flake a long beforeAll hook (hookTimeout 10s) under loadavg 40+; re-run at lower load before diagnosing code.", "environment": "", "language": "", "model": "openrouter/deepseek/deepseek-v4.1-flash", "problem_class": "gitreins-tier1-guard-step-timeout-120s-default", "provider": "openrouter", "solved_at": "2026-10-02T06:50:02.055Z", "version": ""}
