All `return []` statements verified as legitimate edge case handling, not stubs.
|
|
|
|
### Human Verification Required
|
|
|
|
None - all must-haves verified programmatically. The following items could optionally be verified by human for complete confidence:
|
|
|
|
1. **Visual appearance check** - Open history page, execute predictV3, verify confidence display and backtest metrics render correctly
|
|
2. **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:
|
|
|
|
1. Confidence percentage displayed for each predicted number (confidence_scores array)
|
|
2. Backtest results include NDCG@5, MRR, hit_distribution (extended _runBacktestV3)
|
|
3. OptimizeWeights API available for weight optimization (controller + model methods)
|
|
4. Second-order Markov used when data sufficient (200+ periods, 30%+ sufficient pairs)
|
|
5. 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.
