+# OpenSpec Change: enterprise-api-plugin-events
+
+- **Change ID**: enterprise-api-plugin-events
+- **Package**: `@suaveplan/api-plugin-events`
+- **Category**: api/content
+- **Target path**: `api/content/api-plugin-events`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/api-plugin-events.md`
+

+
+## Summary
+
+Deliver `@suaveplan/api-plugin-events` on the genesis branch from scratch at enterprise quality. Calendar/events plugin: event management (create/update/cancel), recurring event rules (RRule subset via `@suaveplan/datetime`), RSVP/attendance tracking, venue management, capacity limits, ticketing hooks, and an iCal feed export. Routes under `/events`. Per-table SurrealQL. Typed bus events: `calendar:event:created`, `calendar:event:cancelled`, `calendar:rsvp:confirmed`. Distinct from `@suaveplan/events` (the typed event bus package).
