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

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.

Anti-Patterns Found

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.
