+## Current Test
+
+[awaiting human testing]
+
+## Tests
+
+### 1. Pre-populated task visual rendering
+expected: Open the app on a day that is NOT a task due date for a weekly task (e.g. 3 days before due). Task visible with ~55% opacity in a muted "Demnächst" section below the regular day tasks.
+result: [pending]
+
+### 2. Reactive filtering on completion
+expected: Navigate to a future calendar day for a weekly task and check its checkbox. Task disappears from that day and does not reappear as pre-populated on other days in the same period.
+result: [pending]
+
+### 3. Overdue styling preserved
+expected: Check that an overdue task still shows its coral/terracotta accent colour (0xFFE07A5F) with no opacity reduction.
+result: [pending]
+
+### 4. Flutter test and dart analyze
+expected: Run `flutter test` and `dart analyze` in a Flutter-capable environment. All tests pass; zero issues.
+result: [pending]
