 - Standardized sprint date parsing across Kanban, Backlog, Sprint Board, Archive, and task detail sprint pickers.
 - `POST /api/sprints` and `PATCH /api/sprints` now normalize `startDate`/`endDate` to `YYYY-MM-DD` before writing to Supabase.
 
+### Feb 23, 2026 updates

+- Removed non-live fallback data paths from the task store; board data now comes from Supabase-backed APIs only.
+- Removed legacy schema expectations from API code and docs (`legacy_id`, `meta` dependency, non-existent task columns).
+- Task detail now includes explicit Project + Sprint selection; selecting a sprint auto-aligns `projectId`.
+- API validation now accepts UUID-shaped IDs used by existing data and returns clearer error payloads for failed writes.
