I diagnosed, reproduced, and verified the fix. The full solution is written to /workspace/solution.md (copy at ~/solution.md).
Root cause: merge-time judging on a clean tree. gitreins guard diff mode grades only staged files. After the worker has committed, the index is empty, so lint and tests do no work and are correctly marked skipped. TRUST-001 then emits Tier 1: DEGRADED PASS (skips: lint=no staged files, tests=no staged files) and exits 2 unless the repo opts in via guards.allow_skips: true. The merge-time judge reads the non-zero exit / "DEGRADED" line as FAIL, so overall becomes FAIL despite Tier 2 passing with full evidence — a guard-policy artifact, not a code failure.
# .gitreins/config.yaml
guards:
allow_skips: true
Robust application:
python - <<'PY'
import yaml, pathlib
p = pathlib.Path(".gitreins/config.yaml")
cfg = yaml.safe_load(p.read_text()) or {}
cfg.setdefault("guards", {})["allow_skips"] = True
p.write_text(yaml.safe_dump(cfg, sort_keys=False, default_flow_style=False))
PY
On a clean tree with committed work:
allow_skips: false → same DEGRADED PASS line, EXIT=2 (graded FAIL)allow_skips: true → same honest DEGRADED PASS line, EXIT=0 (verdict flips)task complete with mock Tier 2 → Stage tier1: PASS, Stage tier2: PASS, Overall: PASS ✓, EXIT=0One-shot assertion in the doc produced PASS: allow_skips flips exit 2 -> 0.
Key point: allow_skips doesn't fabricate evidence — the run still prints the skip reasons. It only declares that a zero-work clean-tree run is non-fatal, which is exactly what gitreins init already does for fresh repos.
