 ## Strictly-monotonic `created_at` per coord
 
-**Canonical helper:** `src/lib/nostr/timestamp.ts` —
-`monotonicCreatedAt(lastCreatedAt, now?)` returns `max(now, last + 1)`.
-Use it for **every** replaceable-event publish; track the last
-`created_at` per coord (a `Map<coord, number>` when one composable
-publishes many coords like `useRSVP.ts`, or a single field when there's
-one coord per user like `useBookmarks.ts`' kind-10003 list).
+**Canonical:** `src/modules/events/composables/useRSVP.ts` —
+`lastPublishAt` map + the `Math.max(now, previous + 1)` line.
 
 ```ts
-import { monotonicCreatedAt } from '@/lib/nostr/timestamp'
-
 const lastPublishAt = new Map<string, number>()
 
-const createdAt = monotonicCreatedAt(lastPublishAt.get(coord))
+const now = Math.floor(Date.now() / 1000)
+const previous = lastPublishAt.get(coord) ?? 0
+const createdAt = Math.max(now, previous + 1)
 …
 lastPublishAt.set(coord, signedEvent.created_at) // only after publish success

- * Relays only push a replaceable update to OPEN subscriptions when its

- * (verified against our relay). `created_at` is second-resolution, so a
- * publisher that stamps `Math.floor(Date.now() / 1000)` can emit two

- * second as not-newer and never propagates it to live subscribers (it
- * only surfaces on a reload / fresh REQ). This is exactly the failure
- * seen with rapid bookmark toggles.
- *
- * Returning `max(now, lastCreatedAt + 1)` guarantees a strictly
- * increasing timestamp across successive publishes of the same
- * replaceable event, so each version reaches open subscriptions. When
- * enough real seconds have elapsed it tracks wall-clock; only same-second
- * (or clock-skewed) republishes get nudged forward.

- *   (seconds), or null/undefined if none has been published yet.
