- Plan: a configured supervisor can return structured findings and improvement proposals from retained runner evidence.
- Do: native improvement runners may record a candidate fingerprint and rollback-protected file history.
- Check: the supervisor records a score and approval/rejection outcome when a model profile is configured.
- Act: operators review retained evidence; Orbit does not automatically apply a source change, commit or revert.
Runs retain prompt snapshots, runner results, supervisor responses, score/decision data and trace IDs. Availability of a candidate fingerprint, diff summary and rollback history depends on the runner.
Git commits, patch reverts and PR creation are not implemented by Orbit.
Add isolated candidate diffs, baseline comparison, policy-driven approval, reviewed Git commit/revert and optional PR evidence attachment.
