Fixed several issues that surfaced after the 4-state HMM migration. The dashboard is now stable across all 8 assets. Fixed SPY regime forecasts showing negative probabilities by adding eigen-decomposition stability checks before forecast generation. Resolved Chrome/Recharts memory leak on the comparison tab by switching to lazy loading for asset comparison charts, reducing memory usage by ~40%. Fixed crypto state collapse on volatile days by increasing minimum state occupancy to 5% and re-running with 60 random seeds. Resolved 404 errors on the SHAP endpoint for IWM by fixing feature extraction in the KernelExplainer. Extended Yahoo Finance cache TTL to 7200s with fallback to previous day’s data when rate-limited. Fixed regime confidence display on the live tab by correcting posterior probability parsing. All 8 assets now load correctly across all 3 time periods. Next up: multi-asset portfolio execution endpoint and backtest optimization for 1-year periods.
