 ### Startup
 
-Call `Fetch()` **after** `conn.Start` (consumers bound), never before: events published between the snapshot and the binding would otherwise be lost. authz-service only serves a snapshot whose read view has applied every stored event. It sends that position in the `X-Authz-Sequence` header and answers 503 while the read view lags (backlog, backfill, reset); `Fetch` retries 503 for about a minute. `Fetch` merges the snapshot as facts at that sequence number (newer event facts win, pairs missing from the snapshot are removed) and drops later events at or below it. A snapshot older than one already merged is ignored, so concurrent or repeated fetches are safe. A snapshot without the header merges at 0 and logs a warning (rollout window only).

When the `/authz` contract changes, deploy authz-service before the services that use this library.
 
 Don't combine `Setup()` with go-messaging-amqp's `WithReconnect`: a reconnect declares new per-replica queues, so revocations published during the outage are lost unless `Fetch()` runs again. Services exit on connection loss (`CloseListener`) and re-fetch on start.
