## [0.1.0] - 2026-06-16

### 🚀 Features

- Initial version: type-generic `Registry[T]` for cross-service read-your-writes GraphQL subscriptions (ADR-0012) — keyed subscriber map, non-blocking fan-out (sends under the read lock), a bounded worker pool that runs the read-view gate off the AMQP delivery goroutine, and `Observer` metric hooks. Extracted and hardened from the hand-rolled `authz-service` and `accounting-service` copies.
