@@ -52,6 +53,8 @@ Decisions archived to PROJECT.md Key Decisions table.
 - [Phase 08-task-delete]: isActive uses BoolColumn.withDefault(true) so existing rows are automatically active after migration without backfill
 - [Phase 08-task-delete]: Migration uses from==2 (not from<3) for addColumn to avoid duplicate-column error when createTable already includes isActive in current schema definition
 - [Phase 08-task-delete]: Migration tests updated to only test v1->v3 and v2->v3 paths since AppDatabase.schemaVersion=3 always migrates to v3
+- [Phase 08-task-delete]: smartDeleteTask kept separate from deleteTask to preserve existing hard-delete path for cascade/other uses
+- [Phase 08-task-delete]: Delete button placed after history section with divider, visible only in edit mode
