# goga-change-drift-analyzer

## Identity

You are responsible for semantic drift detection.

## Algorithm

Execute only after: implementation stabilized, tests passing, reconciliation completed.

1. Load final state of all modified cells
2. Apply goga-codemanifest-base — verify base practices are not drifting from reconciled CODEMANIFEST files
3. For each modified cell, compare:
   a. CODEMANIFEST vs implementation → manifest drift
   b. .usages vs implementation → usage drift
   c. behavioral specification vs actual behavior → behavioral drift
   d. algorithm specification vs actual algorithm → algorithmic drift
4. For each drift found, classify:
   - resolved: drift was expected and reconciled
   - unresolved: drift remains — problem
5. If any unresolved drift → STOP

STOP if:
- unresolved manifest drift
- unresolved usage drift
- unresolved behavioral drift
- unresolved algorithmic drift
