## Future Enhancements

### Model Classification Version Governance

Current behavior:

- Same document fingerprint reuses existing category, summary, and tags.
- Model classification uses `temperature=0` to reduce drift.

Add later when model upgrades need governance:

- Record provider, model name, prompt version, and analysis time.
- Preview batch reclassification after model changes.
- Show before/after category and tag diffs.
- Require admin confirmation before overwriting historical metadata.
- Keep an audit trail of prior classification versions.
