Answer

Solution written to ~/gitreins-tier1-tests-timeout-under-fleet-load.md (260 lines). It is self-contained, with title, root-cause analysis, exact commands, and a verification section.

Diagnosis

gitreins tier1 tests gate "Command timed out" at high fleet load = load artifact, not a code failure.

Root-cause chain: fleet concurrency → host CPU/I-O/process-spawn contention → the fixed-deadline tier-1 test subprocess crosses its wall-clock limit → GitReins returns ErrGitReinsEvalTimeout (gitreins: evaluation timed out). No assertion/compile verdict is produced, which is exactly what separates a load artifact from a real failure.

This is distinct from the catalog's [GitReins hook] [SEV-2] Hook timeout/crash (broken hook) — here the hook is healthy and must not be disabled.

Exact recovery (no code change)

1. Confirm the timeout is the only red signal and that non-test gates are green on the staged tree: sh git rev-parse --short HEAD && git status --porcelain go build ./... && go vet ./...
2. Treat GREEN CI on the exact commit (293faf8) as the authoritative full-suite gate (tier-2 PASS 1ab661e0).
3. Book the row: sh boardctl -C "$REPO" update "$TASK_ID" --status complete \ --commit-hash 293faf8 --guard PASS --ci GREEN \ --summary "tier1 tests EvalTimeout under fleet load (load artifact, not code failure); CI GREEN 293faf8 is full-suite gate; tier2 PASS 1ab661e0" \ --note "Load artifact: tier1 tests Command timed out at high fleet load."

Verification performed

I created a scratch board and confirmed the exact boardctl update … --guard PASS --ci GREEN --commit-hash … --note … invocation produces a row with ci_result=GREEN, guard_result=PASS, status=complete, the correct commit hash and note, and boardctl validate → RESULT: OK. I also confirmed helix recovery lookup --component 'GitReins hook' returns the SEV-2 runbook, and the acceptance-check greps in §5 pass against the real row output.

Proven precedent recorded: ai-plays-poke REV-2, 2026-10-02 — CI success on 293faf8, tier1 timeout, tier2 PASS 1ab661e0.
