Version history
v2.12026-04-16
- Scenario builder waterfall redesigned as delta segments (positive deltas extend right in green, negative left in red) with a zero-axis reference
- Profession-gated knobs (E2, E5, S2, S3, S4, S5) render dimmed with a disabled toggle when they don't apply to the selected profession, so partners see why a knob contributes 0 to the decomposition
- Preset chips switched to uniform neutral styling with a small tone dot; active preset is highlighted — removes the stoplight effect
- Financial view selector consolidated into a single 2×3 (scope × geography) dropdown; removed the separate L3/L4 tab switcher
- Export actions consolidated into a single Export ▾ dropdown (cite view / download CSV / print / PDF)
- Dropped the raw-URL display on the scenario share block — kept Copy link and View financial impact CTAs
- Portfolio-mode RSC payload cut 10× (3.6MB → 395KB) by only shipping the full hospital array on hospital view
- HCRIS fixes: NPR-based denominator, classifier priority, payer-mix source tracking
