- NaN composite score: dropna().mean() on empty series returns NaN,
nan is truthy so (nan or 0)=nan. Fixed: use None when no MFE data
so scorer uses 0.5 fallback instead of propagating NaN.
- Analysis stopping: gate WFV was importing from main.execute_run
(old CLI code that uses broken runner). Fixed: gate.run_walk_forward
now accepts an executor callable from optimizer_loop.
- Back to Dashboard opened blank tab: Reports button used
window.open(_blank). Fixed: same-tab navigation + history.back().
- NaN in reports card: downstream of composite_score NaN above.
- Added GitHub URL
- Documented all 6 critical bugs found and fixed:
* UTF-16 LE report encoding
* Report location (appdata root not /reports/)
* INI Period string format (H1 not 16385)
* INI Report relative path
* MQL5 reference syntax
* Stale report detection
- Added full SocketIO events table
- Added baseline run results (597 trades confirmed parsed)
- Updated file structure with all Phase 2 files
- Updated next steps to Phase 3 (PyInstaller packaging)
