COUNTER type: - Only accepts integer values (rejects decimals) - Auto-increment behavior: each mark adds to existing value - Supports decrement via negative values (e.g., -2) - Enforces minimum value of 0 (never negative) - Default increment is 1 if no value provided VALUE type: - Accepts decimal values - Replaces value (no auto-increment) IsNegative field: - New boolean field on Habit entity - Persisted in database (is_negative column) - Available in all DTOs and HTTP responses - Marks habits as "negative" (e.g., candy consumption) Examples: - COUNTER: 5 + (-2) = 3, 2 + (-3) = 0, 0 + (-1) = 0 - VALUE: 5000 → 12000 = 12000 (replacement)
