Wave 10 Summary: - A1-A4: Architecture upgrades (4x network, LeakyReLU, Xavier init, diagnostics) - A5-A6: Integration testing and production validation - A7: Research hyperopt vs manual tuning (manual recommended) - A8-A12: HOLD penalty tuning and critical bug fixes Architecture Changes: - Network expansion: [128,64,32] → [256,128,64] (2.5x parameters) - LeakyReLU activation (alpha=0.01) to prevent dead neurons - Xavier/Glorot initialization for better gradient flow - Real-time diagnostic monitoring (Q-values, dead neurons, gradients) Critical Bugs Fixed: - Bug #1: HOLD penalty not wired to reward calculation - Bug #2: Zero price error in calculate_hold_reward (velocity-based fix) - Huber loss default enabled (Wave 9) - Shape mismatch fix (Wave 8) Test Results: - Integration tests: 149/152 passing (98%) - New tests: 40+ tests added across 15 files - Xavier init: 5/5 tests passing - HOLD penalty wiring: 4/4 tests passing - Zero price fix: 4/4 tests passing Known Issues: - HOLD bias persists at ~100% despite penalties - Gradient collapse: 217 instances per training run (norm=0.0) - Reversed penalty effect: Higher penalties → worse Q-spread - Root cause: Gradient clipping bottleneck (max_norm=10.0 vs penalty signal) Phase 1 Trials (all completed without crashes): - Penalty 0.5: Q-spread 250 pts, HOLD 100% - Penalty 1.0: Q-spread 251 pts, HOLD 100% - Penalty 2.0: Q-spread 255 pts, HOLD 100% (+ Q-value explosion) Next Steps: Architectural investigation via parallel agent debugging 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
