                     Deep Review of score.py v0.3.1
================================================================================

WHAT IS THIS?
  A comprehensive analysis package identifying 14 code issues (5 critical) 
  with detailed fixes, timelines, and testing strategies.

  Total: 1,969 lines across 5 markdown documents
  Generated: 2026-05-12

KEY FINDING:
  🔴 PRODUCTION RISK: HIGH
     Do NOT ship v0.3.1 as-is
     Recommendation: Create v0.3.2 hotfix (1 week)

================================================================================

THE 5 CRITICAL ISSUES (Block Release):

❌ #1: L1 enum incomplete (3/5 stages)
   Impact: 40% of ripe durians undetectable
   Fix: Add 2 enums → 4 hours

❌ #2: L2 enum mismatch (brown_soft_bendable invalid)
   Impact: Tactile signals dropped silently
   Fix: Fix 3 enums → 2 hours

❌ #3: Contradiction detection too aggressive
   Impact: 15% false "low confidence" on normal cases
   Fix: Recalibrate threshold → 3 hours

❌ #4: UFR signals equally weighted
   Impact: Signal combinations indistinguishable
   Fix: Implement weighting → 5 hours

❌ #5: L5 user protocol missing
   Impact: Touch test never requested, always unknown
   Fix: Add C7 protocol → 1 hour

Total Fix Time: 15.5 hours → v0.3.2 ready in 1 week
