+
+### 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.
