@@ -133,20 +133,6 @@ Board ordering behavior:
- The `done` column is recency-ordered by completion time (newest first), using `columnMovedAt` as primary and falling back to `updatedAt` then `createdAt` for legacy tasks.
- The dashboard **list view default ordering matches these same per-column semantics** until a user clicks a sortable header (manual list sorting still overrides defaults).
#### Todo aging indicator
The board Todo column header shows a client-side aging summary for Todo tasks:
- `07d` (fresh)
- `830d` (aging)
- `31+d` (stale)
Age uses this timestamp precedence per task:
1. `columnMovedAt` (preferred; when the task entered Todo)
2. `createdAt` (fallback for legacy rows)
3. `updatedAt` (last resort)
Clicking a bucket filters only the Todo column to that bucket. Clicking the active bucket again clears the filter. The filter is local UI state (not persisted) and resets when navigating away/remounting the board.
