- Fix sqlite3.OperationalError: the recipes table uses `title` not `name`;
get_plan_slots JOIN was crashing every list_plans call with a 500,
making the + New week button appear broken (plans were being created
silently but the selector refresh always failed)
- Add migration 032 to add UNIQUE INDEX on meal_plans(week_start)
to prevent duplicate plans accumulating while the button was broken
- Raise HTTP 409 on IntegrityError in create_plan so duplicates produce
a clear error instead of a 500
- Fix mondayOfCurrentWeek to build the date string from local date parts
instead of toISOString(), which converts through UTC and can produce the
wrong calendar day for UTC+ timezones
- Add planCreating/planError state to MealPlanView so button shows
"Creating..." during the request and displays errors inline
- Add GET /{plan_id}/prep-session endpoint so frontend can retrieve existing sessions without creating
- Fix list_plans response_model from list[dict] to list[PlanSummary] with proper _plan_summary() mapping
- Replace assert in store.update_prep_task with ValueError (assert is stripped under python -O)
- Add day_of_week 0-6 validation to upsert_slot endpoint
- Remove MagicMock sqlite artifact files left by pytest (already in .gitignore)
- upsert_slot: raise 422 immediately if meal_type not in VALID_MEAL_TYPES
- update_prep_task: assert whitelist safety contract after dict comprehension
- CreatePlanRequest: week_start typed as date with must_be_monday validator; str() cast at call site
- PrepTask: frozen=True; build_prep_tasks rewired to use (priority, kwargs) tuples so frozen instances are built with correct sequence_order in one pass (no post-construction mutation)
- Move deferred import json to file-level in meal_plans.py
- Fix test dates: "2026-04-14" was a Tuesday; updated request bodies to "2026-04-13" (Monday)
