The shared core of Shiny's cross-service read-your-writes GraphQL subscriptions (ADR-0012), extracted and hardened from the near-identical hand-rolled handlers in authz-service (availableCompanies) and accounting-service (entryBasesChanged) before a third copy is written. Registry[T] owns the keyed subscriber map, non-blocking buffered fan-out (sends under the read lock so a close can't race a send), a key-sharded worker pool that runs the read-view gate OFF the AMQP delivery goroutine (preserving per-key FIFO order while distinct keys run in parallel), the bounded retry/timeout budget, and Observer metric hooks. Services supply only the event->key+payload mapping, the read-view Producer closure, and the per-replica transient-consumer wiring. Reviewed pre-publish (Go + Event Sourcing + Architecture). 99% coverage, race-clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
