- Migration 007: parent_event_id (self-ref FK CASCADE), is_recurring, original_start columns on calendar_events - CalendarEvent model: three new Mapped[] columns for recurrence tracking - RecurrenceRule Pydantic model: typed schema for every_n_days, weekly, monthly_nth_weekday, monthly_date - CalendarEventCreate/Update: accept structured RecurrenceRule (router serializes to JSON string for DB) - CalendarEventUpdate: edit_scope field (this | this_and_future) - CalendarEventResponse: exposes parent_event_id, is_recurring, original_start - recurrence.py service: generates unsaved child ORM objects from parent rule up to 365-day horizon - GET /: excludes parent template rows (children are displayed instead) - POST /: creates parent + bulk children when recurrence_rule provided - PUT /: scope=this detaches occurrence; scope=this_and_future deletes future siblings and regenerates - DELETE /: scope=this deletes one; scope=this_and_future deletes future siblings; no scope deletes all (CASCADE) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
