+## Implementation Summary
+
+### Changes Made (commit f5f870d)
+
+1. **WebSocket Auth** (`backend/app/api/websocket/router.py`)
+   - Standardized error codes: 4001 (invalid token), 4003 (access denied), 4004 (not found)
+   - Clear error reasons in WebSocket close messages
+
+2. **Optimistic Locking** (`backend/app/api/tasks/router.py`)
+   - 409 Conflict response with standardized payload:
+     - `error: "conflict"`
+     - `message`, `current_version`, `provided_version`, `your_version`
+
+3. **Workload Heatmap** (`backend/app/api/workload/router.py`, `workload_service.py`)
+   - `hide_empty=True` as default
+   - Caching only when `hide_empty=True`
+   - Week bounds handle Sunday correctly (returns previous Monday)
+
+4. **Frontend** (already aligned)
+   - `workload.ts`: `hideEmpty: boolean = true` default
+   - TaskDetailModal, GanttChart, CalendarView: Handle 409 conflict with conflict banner UI
+
+5. **Tests** (`backend/tests/test_workload.py`)
+   - Week bounds tests including Sunday handling
+   - Load level calculation tests
