COMPLETED STORIES:

[✓] Story 1.0: Define habits.json data schema
    Commit: ee8727a
    Date: 2026-02-10
    
    Implementation:
    - Created dashboard/habits.json with proper schema
    - Root structure: lastUpdated (ISO timestamp) + habits (array)
    - Habit schema: id (string), name (string), frequency (daily/weekly), 
      createdAt (ISO), completions (array of ISO dates)
    - Initial file contains empty habits array with current timestamp
    - All JSON validation passes
    
    Tests:
    - Created dashboard/test_habits_schema.py
    - Tests for file existence, valid JSON, root structure
    - Tests for lastUpdated ISO format validation
    - Tests for habits array type
    - Tests for complete habit schema (all required fields + types)
    - Tests for initial empty state
    - All tests pass ✓
    
    Files modified:
    - dashboard/habits.json (created)
    - dashboard/test_habits_schema.py (created)

[✓] Story 2.0: Backend API - GET /api/habits
    Commit: fc5ebf2
    Date: 2026-02-10
    
    Implementation:
    - Added GET /api/habits endpoint to dashboard/api.py
    - Endpoint returns habits array and lastUpdated timestamp
    - Graceful error handling: returns empty array if file missing/corrupt
    - Follows existing API patterns (similar to /api/git, /api/status)
    - Returns 200 status for all valid requests
    
    Tests:
    - Created dashboard/test_habits_api.py
    - Tests for endpoint existence (returns 200)
    - Tests for valid JSON response
    - Tests for response structure (habits array + lastUpdated)
    - Tests for ISO timestamp validation
    - Tests for empty file handling (returns [], not error)
    - Tests for habits with data
    - All 6 tests pass ✓
    
    Files modified:
    - dashboard/api.py (added handle_habits_get method + route)
    - dashboard/test_habits_api.py (created)

CODEBASE PATTERNS:

1. JSON Data Files
   - Location: dashboard/*.json
   - Pattern: Similar structure to tasks.json, todos.json, issues.json
   - All use ISO timestamps for dates
   - Root objects contain metadata + data arrays

2. Testing Approach
   - Python test files in dashboard/ directory
   - Test naming: test_*.py
   - Comprehensive validation: existence, JSON validity, schema, types
   - Run tests from repo root with: python3 dashboard/test_*.py

3. Build Validation
   - Command: python3 -m py_compile dashboard/api.py
   - Validates Python syntax without executing

4. Utility Functions in api.py
   - Standalone utility functions placed before TaskBoardHandler class
   - Documented with docstrings (Args, Returns, Rules/behavior)
   - ISO timestamp parsing pattern: datetime.fromisoformat(ts.replace('Z', '+00:00'))
   - Convert to date only when time doesn't matter: dt.date()
   - Use try/except for robust parsing with sensible defaults (return 0, [], etc.)

[✓] Story 3.0: Backend API - POST /api/habits (create habit)
    Commit: 3a09e6c
    Date: 2026-02-10
    
    Implementation:
    - Added POST /api/habits endpoint to dashboard/api.py
    - Accepts {name, frequency} in request body
    - Returns 400 for missing name or empty name (after trim)
    - Returns 400 for invalid frequency (must be 'daily' or 'weekly')
    - Generates unique id following format 'habit-{millisecond_timestamp}'
    - Sets createdAt to current ISO timestamp
    - Initializes completions array as empty
    - Persists new habit to habits.json
    - Updates lastUpdated timestamp in habits.json
    - Returns 201 status with created habit object
    - Graceful handling of missing/corrupt habits.json file
    
    Tests:
    - Created dashboard/test_habits_post.py
    - Tests for successful habit creation (returns 201 + full habit object)
    - Tests for habit persistence to habits.json
    - Tests for correct id format (habit-{timestamp})
    - Tests for missing name validation (400)
    - Tests for empty name validation (400)
    - Tests for invalid frequency validation (400)
    - Tests for missing frequency validation (400)
    - Tests for creating multiple habits (unique IDs)
    - Tests for lastUpdated timestamp update
    - All 9 tests pass ✓
    
    Files modified:
    - dashboard/api.py (added handle_habits_post method + route)
    - dashboard/test_habits_post.py (created)

[✓] Story 4.0: Backend API - Streak calculation utility
    Commit: 3927b7c
    Date: 2026-02-10
    
    Implementation:
    - Created calculate_streak(completions, frequency) utility function
    - Added to dashboard/api.py as standalone function (before TaskBoardHandler class)
    - Accepts completions array (ISO timestamps) and frequency ('daily' or 'weekly')
    - Returns integer streak count (days for daily, weeks for weekly)
    - Daily habits: counts consecutive days without gaps
    - Weekly habits: counts consecutive weeks (7-day periods)
    - Returns 0 for no completions, invalid dates, or broken streaks
    - Edge case: today's completion counts even if streak was 0 yesterday
    - Edge case: multiple completions same day/week count as one period
    - Robust date parsing with error handling for invalid ISO timestamps
    
    Tests:
    - Created dashboard/test_habits_streak.py
    - Tests for no completions (returns 0)
    - Tests for daily single completion (today and yesterday)
    - Tests for daily consecutive days (5 days streak)
    - Tests for daily broken streak (gap detection)
    - Tests for daily old completion (>1 day ago returns 0)
    - Tests for weekly single completion (this week)
    - Tests for weekly consecutive weeks (4 weeks streak)
    - Tests for weekly broken streak (missing week)
    - Tests for weekly old completion (>7 days ago returns 0)
    - Tests for multiple completions same day (deduplicated)
    - Tests for today counting despite yesterday missing
    - Tests for invalid date format handling
    - Tests for weekly multiple in same week (deduplicated)
    - All 14 tests pass ✓
    - All previous tests (schema, GET, POST) still pass ✓
    
    Files modified:
    - dashboard/api.py (added calculate_streak function)
    - dashboard/test_habits_streak.py (created)

[✓] 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

    - 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 ✓
