SxExpr is now a str subclass so it works everywhere a plain string does (join, isinstance, f-strings) while serialize() still emits it unquoted. sx_call() and all internal render functions (_render_to_sx, async_eval_to_sx, etc.) return SxExpr, eliminating the "forgot to wrap" bug class that caused the sx_content leak and list serialization bugs. - Phase 0: SxExpr(str) with .source property, __add__/__radd__ - Phase 1: sx_call returns SxExpr (drop-in, all 200+ sites unchanged) - Phase 2: async_eval_to_sx, async_eval_slot_to_sx, _render_to_sx, mobile_menu_sx return SxExpr; remove isinstance(str) workaround - Phase 3: Remove ~150 redundant SxExpr() wrappings across 45 files - Phase 4: serialize() docstring, handler return docs, ;; returns: sx Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Models
All events-domain models live in shared/models/:
| Model | Description |
|---|---|
| Calendar | Container for entries, scoped to a page via container_type + container_id |
| CalendarEntry | A bookable event/time slot with state (pending/ordered/provisional) and cost |
| CalendarSlot | Recurring time bands (day-of-week + time range) within a calendar |
| TicketType | Named ticket categories with price and count |
| Ticket | Individual ticket with unique code, state, and order_id (plain integer, no FK) |
| CalendarEntryPost | Junction linking entries to content via content_type + content_id |
order_id on CalendarEntry and Ticket is a plain integer column — no FK constraint to the orders table. The cart app writes these values via service calls, not directly.
