# RG100 AI agent regression change worksheet

Freeze one exact baseline and candidate, map the change radius, execute paired repetitions, reconcile traces and effects, triage every material difference and observe only an approved bounded stage.

## Twelve governed record groups

1. Change identity and accountable owner
2. Baseline BM11 immutable manifest
3. Candidate CM12 immutable manifest
4. Intended behavior and prohibited outcomes
5. Change-radius map and omitted-case rationale
6. Persistent cases, fixtures and data classification
7. Deterministic invariants and variable tolerances
8. Repetition, seed and environment reset rules
9. Trace, authoritative state and effect-ledger checks
10. Severity, veto, waiver and separation-of-duty rules
11. Stage cohort, duration, limits and stop rules
12. Rollback identity, effect reconciliation and final decision

## State rule

Use `DRAFT → RADIUS_REVIEWED → RUN_COMPLETE → TRIAGED → APPROVED_FOR_STAGE → STAGED → PROMOTED` only when the exact evidence exists. Preserve missing repetitions and failed denominators. A permission, privacy, tenant-isolation, credential, irreversible-effect or duplicate-effect veto keeps promotion blocked regardless of an aggregate score.
