- Doc status click-to-update: SWO and PA cycle through states and persist to Supabase - Status legend added to worklist header - Empty state with file-open prompt for first-time users - Device normalizer expanded for broader CGM variant coverage - Warm cream text applied globally for secondary/muted UI elements - Drag-drop CSV import support - CORS root cause fixed via Railway ALLOWED_ORIGINS env var - DOCS_REQUIRED badge: RESUPPLY_READY patients with open cascade items now show amber Docs Required instead of green Clear to Ship, preventing premature shipment Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
