- 2026-05-29Phase 1 Batch J: per-group recovery resources applied via programmatic palette (closest-fit by category + subCategory + score). Palette: Mainstream-comparator lighter.
- 2026-05-20Score band scheme migrated from 4 bands to 5 (Minimal 0–5 / Low 6–12 / Moderate 13–20 / High 21–30 / Extreme 31–40). No CLCI value changed; the new Minimal band was carved out of the bottom of the previous Low band.
