// ── The events admin surface (EVENTS.md § API surface, Phase 1) ────────────
//
// `eventSpec.test.js` covers the spec validator and `eventActionRegistry.test.js`
// the registry; re-asserting either here would be a second copy of a test rather
// than a second test. What is genuinely new is what the SURFACE decides:
//
//   • **publish snapshots.** It cuts an immutable version, points the definition
//     at it, and a later edit does not touch the version a run would pin.
//   • **publish re-validates against the registries as they stand now**, not
//     against the save that wrote the spec. A module uninstalled in between must
//     block the publish, because the alternative is a run that fails at dispatch
//     with the world half-changed.
//   • **an empty event does not publish.** It would run cleanly and do nothing,
//     which reads as a broken run rather than an empty one.
//   • **the slug is frozen after create**, because the public event page lives
//     at it and a retitle must not break a posted link.
//   • **archiving is refused while a run is in flight**, and there is no hard
//     delete at all.
//   • **creating an occurrence twice creates ONE run.** The unique index is what
//     makes that true, so the second call answers `created: false` with the
//     existing row rather than erroring.
//   • **a created run stays `scheduled`.** There is no runner until Phase 2, and
//     that has to be visible as the correct state rather than as a stall.
//
// The `.db` layer is stubbed in-memory and the real models and controllers run
// against it, the shape `engagementAdmin.test.js` uses.
