 5. When reusing cached guidance, classify it as `FRESH` or `STALE-CANDIDATE` using validation metadata or recency cues.
 6. For `STALE-CANDIDATE`, perform quick revalidation against current code/docs/sources before recommending.
 7. Include a compact freshness note per key recommendation in output.
 8. Use the lead.md freshness metadata schema for notes/updates: `confidence`, `last_validated`, `volatility`, `review_after_days`, `validation_count`, `contradiction_count`.
 9. Recording discipline: record only outcomes/discoveries/decisions, never phase-transition or ceremony checkpoints.
+10. `.memory/*` writes are allowed for research recording duties; code/source edits remain read-only.
