All Scenarios — Summary (S01–S15 Standard, ER01–ER08 + ER-LV01–LV03 Easy Refi)

All scenarios are validated by automated tests on every run. Live-verified scenarios have been individually confirmed against the Highlighter UI (minimum 5 per verification session). Design-derived scenarios follow the same policy rules and are regression-tested on every commit. Easy Refi scenarios (ER) show allPass outcome rather than NDI ratio.
