  - Repeated corrections (2+ times)
  - Historical references: "cum am discutat", "as we discussed"
- New /learn:cleanup command for memory hygiene
  - Scoring system for entry quality
  - Conservative mode with confirmation
  - Upgrade option to rewrite entries
- SessionEnd hook shows reminder on /exit, /clear, Ctrl+D
