# Unknowns ranking

Unknowns are prioritized using a deterministic, multi-factor score and
assigned to triage bands that drive rescan scheduling.

Scoring formula
- Score = wP*P + wE*E + wU*U + wC*C + wS*S (clamped to 0.0-1.0).
- Factors: Popularity (P), Exploit potential (E), Uncertainty density (U),
  Centrality (C), Staleness (S).
- Default weights: P 0.25, E 0.25, U 0.25, C 0.15, S 0.10.

Band thresholds
- HOT: score >= 0.70 (immediate rescan, 15-minute cadence).
- WARM: 0.40 <= score < 0.70 (scheduled rescan, 12-72 hours).
- COLD: score < 0.40 (weekly batch).

Determinism and replay
- Each scored unknown stores a normalization trace with raw values,
  normalized values, weights, and computed score.
- Replaying the trace yields the same score and band.
