+# V1 Test Coverage Matrix
+
+Status: Current after Block 10.1 audit.
+
+## Scheduling rule coverage
+
+| V1 behavior | Status | Representative coverage |
+| --- | --- | --- |
+| Flexible insert into a free slot | Covered | `test/scheduling_engine_test.dart` verifies inserting a backlog task into an open 20-minute slot. `test/edge_case_regression_test.dart` verifies next-available insertion uses the earliest fitting open slot. |
+| Flexible insert pushes other flexible tasks | Covered | `test/scheduling_engine_test.dart` verifies inserting before a flexible task and pushing the later task. `test/quick_capture_test.dart` verifies immediate scheduling uses normal insertion and push rules. |
+| Locked blocks are never moved | Covered | `test/scheduling_engine_test.dart` verifies inserts skip locked time and respect expanded locked blocks. `test/timeline_state_test.dart` verifies locked occurrences expose overlay data without becoming task items. |
+| Inflexible tasks are never moved | Covered | `test/scheduling_engine_test.dart` verifies inserts do not move inflexible items. `test/required_task_actions_test.dart` verifies invalid push destinations leave fixed task types unchanged. |
+| Critical tasks remain visible and required | Covered | `test/scheduling_engine_test.dart` verifies inserts do not move critical items. `test/required_task_actions_test.dart` verifies missed critical tasks move to backlog with schedule cleared, and required push actions keep fixed items visible. |
+| Push to next available | Covered | `test/required_task_actions_test.dart` verifies the next-available push destination uses the scheduling engine. `test/scheduling_engine_test.dart` verifies a flexible task moves after the current slot. |
+| Push to tomorrow top of queue | Covered | `test/required_task_actions_test.dart` verifies tomorrow top-of-queue metadata. `test/scheduling_engine_test.dart` verifies tomorrow placement respects required and locked time. |
+| Push to backlog | Covered | `test/required_task_actions_test.dart` verifies backlog push clears active schedule placement. `test/edge_case_regression_test.dart` verifies backlog moves do not duplicate task IDs. |
+| End-of-day rollover | Covered | `test/scheduling_engine_test.dart` verifies unfinished flexible tasks roll to tomorrow in order and fixed/completed/cancelled items are excluded. `test/edge_case_regression_test.dart` verifies rollover uses an explicit source window and ignores future tasks. |
+| Required task states | Covered | `test/required_task_actions_test.dart` verifies done, missed, cancelled, no-longer-relevant, backlog, and invalid push state transitions for required task types. |
+| Surprise task overlaps | Covered | `test/surprise_task_logging_test.dart` verifies surprise tasks keep overlap metadata, can coexist with other scheduled items, and preserve the expected timeline order. |
+| Child task parent completion | Covered | `test/child_tasks_test.dart` verifies parent-child ownership, child ordering, child movement, parent auto-completion, and no dependency graph behavior. |
+| Timeline state mapping | Covered | `test/timeline_state_test.dart` verifies visible task mapping, required visibility, hidden locked overlay state, reveal state, manual compact mode, and timeline ordering. |
+| Persistence-sensitive model behavior | Covered | `test/persistence_edge_cases_test.dart`, `test/document_mapping_test.dart`, and `test/repositories_test.dart` verify MongoDB-shaped document mapping, enum/date persistence names, repository contracts, and in-memory repository behavior. |
+
+## Block 06-09 regression representation
+
+| Area | Status | Representative coverage |
+| --- | --- | --- |
+| Quick capture and backlog ordering | Covered | `test/edge_case_regression_test.dart` covers quick-capture title validation, immediate scheduling behavior, and stale backlog age preservation. |
+| Scheduling edge cases | Covered | `test/edge_case_regression_test.dart` covers earliest fitting insertion, locked-boundary placement, fixed item preservation, rollover windows, and backlog ID uniqueness. |
+| Required task action edge cases | Covered | `test/required_task_actions_test.dart` covers non-punitive terminal states and fixed-task push guards. |
+| Locked time and timeline overlays | Covered | `test/timeline_state_test.dart` covers hidden locked time, revealed overlay state, compact mode, and overlay/task separation. |
+| MongoDB persistence boundary | Covered | `test/persistence_edge_cases_test.dart`, `test/document_mapping_test.dart`, and `test/repositories_test.dart` cover document-shaped serialization without adding a MongoDB runtime dependency. |
+
+## Audit result
+
+No uncovered implemented V1 scheduling behavior was found during this audit, so no production code or new tests were required for Chunk 10.1.
