// ── Admin: events ──────────────────────────────────────────────────────────
//
// EVENTS.md § API surface, Phase 1. Definitions CRUD, publish, archive, the
// action catalog and the run reads.
//
// This file reads ids out of URLs and shapes responses; it validates nothing.
// Every decision lives in `model/events/*.model.js` and in `events/spec.js`, so
// a definition arriving from a future import or a restore gets the same answer
// this screen does.
//
// **Phase 3 added the live run controls** at the bottom of this file: pause,
// resume, cancel, and a step's confirm, skip and retry. What is still absent is
// `advance`, `cleanup` and the action switchboard — `advance` has no honest
// meaning until Phase 5 gives a phase an advance condition, `cleanup` has no
// ledger to work over until Phase 8, and the switchboard is Phase 6's. Each of
// them is absent rather than stubbed, for the reason the whole set was in Phase
// 1: a control that returns 200 and does nothing is worse than one that is not
// there.
