+[✓] Story 5.0: Backend API - POST /api/habits/{id}/check
+    Commit: ca4ee77
+    Date: 2026-02-10
+    
+    Implementation:
+    - Added POST /api/habits/{id}/check endpoint to dashboard/api.py
+    - Extracts habit ID from URL path (/api/habits/{id}/check)
+    - Adds today's date (YYYY-MM-DD) to completions array
+    - Returns 400 if habit already checked today
+    - Returns 404 if habit ID not found
+    - Sorts completions chronologically (oldest first) after adding
+    - Uses ISO date format YYYY-MM-DD (not full timestamps)
+    - Calculates and returns streak using calculate_streak utility
+    - Returns 200 with updated habit object including streak
+    - Streak is calculated but not persisted (only in response)
+    - Updates lastUpdated timestamp in habits.json
+    - Graceful error handling for missing/corrupt files
+    
+    Tests:
+    - Created dashboard/test_habits_check.py
+    - Tests for successful habit check (returns 200 + updated habit)
+    - Tests for already checked validation (400 error)
+    - Tests for habit not found (404 error)
+    - Tests for persistence to habits.json
+    - Tests for chronological sorting of completions
+    - Tests for streak calculation in response
+    - Tests for weekly habit checking
+    - Tests for ISO date format (YYYY-MM-DD, no time)
+    - All 8 tests pass ✓
+    - All previous tests (schema, GET, POST, streak) still pass ✓
+    
+    Files modified:
+    - dashboard/api.py (added handle_habits_check method + route in do_POST)
+    - dashboard/test_habits_check.py (created)
+    - dashboard/habits.json (reset to empty for testing)

+[✓] Story 6.0: Backend API - GET /api/habits with streaks
+    Commit: c84135d
+    Date: 2026-02-10
+    
+    Implementation:
+    - Enhanced GET /api/habits endpoint to include calculated streaks
+    - Each habit in response now includes 'streak' field (integer)
+    - Each habit in response now includes 'checkedToday' field (boolean)
+    - Streak is calculated using the calculate_streak utility function
+    - checkedToday checks if today's date (YYYY-MM-DD) is in completions array
+    - All original habit fields are preserved in response
+    - Get today's date once and reuse for all habits (efficient)
+    - Enhanced habits array built by looping through each habit and adding fields
+    - Updated docstring to reflect new functionality
+    
+    Tests:
+    - Created dashboard/test_habits_get_enhanced.py
+    - Tests for streak field inclusion in response
+    - Tests for checkedToday boolean field inclusion
+    - Tests for correct streak calculation (daily and weekly habits)
+    - Tests for broken streaks (should return 0)
+    - Tests for empty habits array handling
+    - Tests for preservation of original habit fields
+    - All 5 tests pass ✓
+    - All previous tests (schema, GET, POST, streak, check) still pass ✓
+    
+    Files modified:
+    - dashboard/api.py (enhanced handle_habits_get method)
+    - dashboard/test_habits_get_enhanced.py (created)
