# Phase 6: Task History Verification Report
|
|
|
|
**Phase Goal:** Users can see exactly when each task was completed in the past, building trust that the scheduling loop is working correctly
|
|
**Verified:** 2026-03-16T22:15:00Z
|
|
**Status:** PASSED
|
|
**Re-verification:** No — initial verification

## Goal Achievement

|
### Observable Truths
|
|
|
|
| # | Truth | Status | Evidence |
|
|
|---|-------|--------|----------|
|
|
| 1 | Every task completion is recorded with a timestamp and persists across app restarts | VERIFIED | `watchCompletionsForTask` reads from `TaskCompletions` table (persistent SQLite); `completeTask` already wrote timestamps; 5 DAO tests confirm stream returns correct data including stream reactivity test |
|
|
| 2 | User can open a history view from the task edit form showing all past completion dates in reverse-chronological order | VERIFIED | `task_form_screen.dart` lines 192-204: `if (widget.isEditing)` guard shows `ListTile` with `onTap: () => showTaskHistorySheet(...)`. Sheet uses `StreamBuilder` on `watchCompletionsForTask` with `..orderBy([(c) => OrderingTerm.desc(c.completedAt)])`, renders dates as `dd.MM.yyyy` + `HH:mm` via intl |
|
|
| 3 | History view shows a meaningful empty state if the task has never been completed | VERIFIED | `task_history_sheet.dart` lines 70-87: `if (completions.isEmpty)` branch renders `Icon(Icons.history, size: 48)` + `Text(l10n.taskHistoryEmpty)` ("Noch nie erledigt") |
|
|
|
|
**Score:** 3/3 truths verified

### Required Artifacts
|
|
|
|
| Artifact | Provides | Status | Details |
|
|
|----------|---------|--------|---------|
|
|
| `lib/features/tasks/data/tasks_dao.dart` | `watchCompletionsForTask(int taskId)` stream method | VERIFIED | Method exists at line 85, returns `Stream<List<TaskCompletion>>`, ordered by `completedAt DESC`, 110 lines total |
|
|
| `lib/features/tasks/presentation/task_history_sheet.dart` | Bottom sheet displaying task completion history | VERIFIED | 137 lines, exports top-level `showTaskHistorySheet()`, `_TaskHistorySheet` is a `ConsumerWidget` with full StreamBuilder, empty state, date list |
|
|
| `lib/features/tasks/presentation/task_form_screen.dart` | Verlauf button in edit mode opening history sheet | VERIFIED | Imports `task_history_sheet.dart` (line 13), `showTaskHistorySheet` called at line 199, guarded by `if (widget.isEditing)` |
|
|
| `lib/features/home/presentation/calendar_task_row.dart` | onTap navigation to task edit form | VERIFIED | `ListTile.onTap` at line 39 calls `context.go('/rooms/${taskWithRoom.roomId}/tasks/${taskWithRoom.task.id}')` |
|
|
| `test/features/tasks/data/task_history_dao_test.dart` | Tests for completion history DAO query | VERIFIED | 158 lines, 5 tests: empty state, single completion, multiple reverse-chronological, task isolation, stream reactivity — all pass |
|
|
| `lib/features/tasks/data/tasks_dao.g.dart` | Drift-generated mixin (build_runner output) | VERIFIED | Exists, 25 lines, regenerated with `taskCompletions` table accessor present |

### Key Link Verification

|
| From | To | Via | Status | Details |
|
|
|------|----|-----|--------|---------|
|
|
| `task_form_screen.dart` | `task_history_sheet.dart` | `showTaskHistorySheet` call in Verlauf `onTap` | WIRED | Import at line 13; called at line 199 inside `if (widget.isEditing)` block |
|
|
| `task_history_sheet.dart` | `tasks_dao.dart` | `watchCompletionsForTask` stream consumption | WIRED | `ref.read(appDatabaseProvider).tasksDao.watchCompletionsForTask(taskId)` at lines 59-62; stream result consumed by `StreamBuilder` builder |
|
|
| `calendar_task_row.dart` | `TaskFormScreen` | GoRouter navigation on row tap | WIRED | `context.go('/rooms/${taskWithRoom.roomId}/tasks/${taskWithRoom.task.id}')` at line 39-41; route `/rooms/:roomId/tasks/:taskId` resolves to `TaskFormScreen` per router.dart |

### Requirements Coverage
|
|
|
|
| Requirement | Source Plan | Description | Status | Evidence |
|
|
|-------------|------------|-------------|--------|----------|
|
|
| HIST-01 | 06-01-PLAN.md | Each task completion is recorded with a timestamp | SATISFIED | `TasksDao.completeTask()` inserts into `TaskCompletions` (pre-existing); `watchCompletionsForTask` surfaces data; 5 DAO tests confirm timestamps are stored and retrieved correctly |
|
|
| HIST-02 | 06-01-PLAN.md | User can view past completion dates for any individual task | SATISFIED | Full UI chain: `CalendarTaskRow.onTap` -> `TaskFormScreen` (edit mode) -> "Verlauf" `ListTile` -> `showTaskHistorySheet` -> `_TaskHistorySheet` StreamBuilder showing reverse-chronological German-formatted dates |
|
|
|
|
No orphaned requirements — REQUIREMENTS.md Traceability table shows only HIST-01 and HIST-02 mapped to Phase 6, both accounted for and marked Complete.

|
|
|
None. No TODOs, FIXMEs, placeholder returns, empty handlers, or stub implementations found in any of the 5 modified source files.

### Human Verification Required
|
|
|
|
#### 1. Tap-to-edit navigation in running app
|
|
|
|
**Test:** Launch app, ensure at least one task exists on the calendar, tap the task row (not the checkbox).
|
|
**Expected:** App navigates to `TaskFormScreen` in edit mode showing the task's fields and a "Verlauf" row at the bottom.
|
|
**Why human:** GoRouter navigation with `context.go` cannot be verified by static analysis; requires runtime rendering.
|
|
|
|
#### 2. History sheet opens with correct content
|
|
|
|
**Test:** In `TaskFormScreen` edit mode, tap the "Verlauf" ListTile.
|
|
**Expected:** Bottom sheet slides up showing either: (a) the empty state with a history icon and "Noch nie erledigt", or (b) a list of past completions with `dd.MM.yyyy` dates as titles and `HH:mm` times as subtitles, newest first.
|
|
**Why human:** `showModalBottomSheet` rendering and visual layout cannot be verified by static analysis.
|
|
|
|
#### 3. Live update after completing a task
|
|
|
|
**Test:** Complete a task via checkbox in the calendar, then navigate to that task's edit form and tap "Verlauf".
|
|
**Expected:** The newly recorded completion appears at the top of the history sheet with today's date and approximate current time.
|
|
**Why human:** Real-time stream reactivity through the full UI stack (checkbox -> DAO write -> stream emit -> sheet UI update) requires runtime observation.
|
|

### Verification Summary
|
|
|
|
All automated checks passed with no gaps found.
|
|
|
|
**Test suite:** 106/106 tests pass (101 pre-existing + 5 new DAO tests covering all specified behaviors).
|
|
**Static analysis:** `flutter analyze --no-fatal-infos` — zero issues.
|
|
**Commits verified:** All three phase commits exist (`2687f5e`, `ceae7d7`, `9f902ff`) with expected file changes.
|
|
|
|
The full feature chain is intact:
|
|
- `TaskCompletions` table stores timestamps (HIST-01, pre-existing from data layer)
|
|
- `watchCompletionsForTask` surfaces completions as a live Drift stream
|
|
- `task_history_sheet.dart` renders them in German locale with reverse-chronological ordering and a meaningful empty state
|
|
- `TaskFormScreen` (edit mode only) provides the "Verlauf" entry point
|
|
- `CalendarTaskRow` onTap makes history reachable from the home calendar in two taps
|
|
|
|
Three human-only items remain for final sign-off: tap navigation, sheet rendering, and live update after completion.
