Epic: #4 (Compounding Measurement)

Task

Keep the knowledge store fresh. Facts go stale. Facts get contradicted.

Validator

  • Periodically check if stored facts are still true
  • High-confidence facts: check weekly
  • Low-confidence facts: check daily
  • Use a lightweight LLM call to verify against recent session data

Decay

  • If a fact hasn't been confirmed in N sessions, reduce confidence
  • Confidence below 0.3 → archive (don't delete, just don't inject)
  • Decay rate: -0.05 per week without confirmation

Contradiction Detection

  • When harvester extracts a fact that contradicts an existing one
  • Flag both for review
  • Higher-confidence source wins automatically
  • Log contradiction for metrics

Acceptance Criteria

  • Stale facts detected and decayed
  • Contradictions flagged and resolved
  • No false positives on facts that are just rare (not stale)
  • Validator runs as part of daily cron
