1. CRITICAL FIX - Reports 500 Internal Server Error:
Root cause: {{}} in onclick was Jinja2 template expression
Fix: Changed to single {} in reports_index.html onclick
2. Score history chart always empty:
Root cause: score_update only emitted inside wfv.passed block
Fix: Emit score_update after every hypothesis run with {promoted:false}
Fix: Baseline run also pushes to chart via run_complete handler
3. IS gate too strict - optimizer produces 0 candidates forever:
Root cause: min_calmar=0.35 but best EA has calmar=0.165
Fix: Two-tier IS check - passes if composite_score improves vs baseline
(absolute thresholds still apply as alternative pass condition)
4. Findings emitted twice (double UI display):
Root cause: baseline analyzed once after run, then re-analyzed in iter 1
Fix: Cache baseline findings, reuse in iteration 1 without re-emitting
5. Chart labels improved:
'Baseline' for first point, 'It1·h1' for hypothesis runs
Calmar normalized -0.5..2.0 -> 0..1 for chart display
6. Best score header only updates on actual promotion (not per-hypothesis)
