Output per failure
### Failure — branch @ sha
- Job / step:
- Error (1-3 lines):
- Classification: flake | regression | env | config
- Actionable: yes | no
- Suggested loop action: minimal-fix | watch | escalate-human
Classification Rules
- flake: intermittent, passed on retry, no code change
- regression: new failure correlated with recent commit
- env: runner, registry, secrets, quota
- config: workflow, dependency install, cache
Env failures → escalate-human. Do not "fix" with code changes.
