Human Verification Required
None - all must-haves verified programmatically. The following items could optionally be verified by human for complete confidence:
- Visual appearance check - Open history page, execute predictV3, verify confidence display and backtest metrics render correctly
- Actual API response check - Execute optimizeWeights API and verify response structure
Summary
Phase 11-predictv3 has achieved its goal. All 5 ROADMAP success criteria are verified:
- Confidence percentage displayed for each predicted number (confidence_scores array)
- Backtest results include NDCG@5, MRR, hit_distribution (extended _runBacktestV3)
- OptimizeWeights API available for weight optimization (controller + model methods)
- Second-order Markov used when data sufficient (200+ periods, 30%+ sufficient pairs)
- All new methods have function-level comments (10 methods with docblocks)
All 20 must-haves from the 5 PLAN files are verified. No anti-patterns found. No gaps identified.
