-- @suaveplan/api-plugin-events — SurrealDB schema
--
-- This migration ships a slimmed-down version of the upstream
-- `event.surql` covering only the tables the repositories actually
-- read / write. The upstream PERMISSIONS rules, stored helper
-- functions, and the `event_update` table are scoped out per
-- `openspec/changes/add-api-plugin-events/proposal.md` because they
-- transitively depend on sibling plugins (site, group, notifications,
-- bitwise) that have not yet been migrated to genesis. Permission
-- enforcement lives at the route / repository layer in the meantime.
