- Drift 21 tables (8 catalog + 11 user + habit_dose_variants + meta_kv) with R1~R10 CHECK constraints and 19 indexes - 8 hand-crafted seed JSON catalogs in app/assets/seed/ (refs 84, protocols 34, methodologies 21, frame_patterns 30, reward_menu_items 30, break_protocols 8, common_frames 5, diet_patterns 5) - 6 domain functions: recommend_variant, compute_streak, validate_frame_level, active_habit_quota, weekly_minimum_ratio, seed_importer (transactional, idempotent) - 4 vertical-slice Riverpod screens: HabitList, HabitCreate, CheckIn, Streak - 31 unit tests passing; flutter analyze clean - OQ-5 streak semantics: missing entry ≠ explicit blank (missing = end of history; only TrackerValue.blank triggers Never-miss-twice) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
