Redis subscription failures currently crash the new notifications-gateway process, and we lost all automated coverage for the new gateway stack. Please fix the Redis error handling and add tests for the extracted service before we merge.

+      this.emit('ready');
+    });
+    await this.redis.connect();
+    await this.redis.subscribe(this.options.channel, (err) => {


[major] already returns a promise that rejects when the command fails. Adding a callback and throwing from inside it means a subscription failure (bad credentials, dropped connection, etc.) will bubble up as an unhandled exception on the Redis event loop and crash the process. We should either remove the callback entirely and rely on the promise rejection, or wrap the callback in a try/catch that rejects /emits an error instead of throwing synchronously. Right now a transient subscribe error will bring down the whole gateway with no recovery path.

✅ Addressed in 338cb1a: now awaits the promise returned by , wraps it in try/catch, logs via , and emits an event before rethrowing. A failed SUBSCRIBE no longer throws from inside the ioredis callback or crashes the process without context.

✅ Addressed in the latest revision: NotificationsSubscriber.start() now awaits the promise returned by redis.subscribe, wraps it in try/catch, logs via serializeError, and emits an error event before rethrowing. A failed SUBSCRIBE no longer throws from inside the ioredis callback or crashes the process without context.

+    await this.redis.connect();
+    await this.redis.subscribe(this.options.channel, (err) => {


[major] If the SUBSCRIBE command fails (bad config, Redis ACLs, transient network error, etc.) this code throws inside the ioredis callback, which propagates as an uncaught exception on the subscriber connection and crashes the whole gateway. Instead of throwing from the callback, rely on the promise returned by redis.subscribe (no callback) or reject start() explicitly and let callers decide how to handle the failure. We need to fail the start sequence cleanly, not bring the process down from inside an event handler.

Thanks for the fix—NotificationsSubscriber now handles subscription failures by logging + emitting and then propagating the error, so start() fails fast and the process stays in control.

[major] This PR moves all real-time delivery logic into a brand-new service, but the gateway package ships with zero automated tests while the former GraphSocketGateway integration/unit suites were deleted. We now have no coverage proving that the subscribe handler validates payloads, that Redis envelopes are parsed correctly, or that dispatch failures surface. Please add unit tests (for config parsing, NotificationsSubscriber, dispatchToRooms, subscribe ack handling, etc.) so we keep the same level of safety we had before the extraction.

New coverage looks good: dispatchToRooms and NotificationsSubscriber each have focused Vitest suites (see src/dispatch.test.ts and src/redis/notifications-subscriber.test.ts), plus the package now ships with its own Vitest config and script. That replaces the deleted GraphSocketGateway tests and gives us automated validation for the extracted service.

Addressed by guarding Redis subscribe failures (logging + error emission) and by adding Vitest coverage for the gateway subscriber/dispatch flows. Let me know if you’d like any additional cases.

Redis subscription failures are now surfaced without crashing, and the new gateway ships with targeted Vitest coverage for dispatch + subscriber logic. Looks good to me.

Rebased changes just move the shared graph/reference types into the @agyn/shared package and wire the new gateway validation helpers—nothing concerning. The tests still cover the Redis subscriber + dispatch flows, so this remains good to merge.

NotificationsPublisher wiring, Redis broker integration, Envoy routing, and the docker-compose.e2e stack all look solid. The new tests around the publisher metrics coalescing, EventsBus bridge, and notifications-gateway dispatch/subscriber paths cover the regressions I was worried about. Approving.

Notes

Could not run docker compose up -d redis because the Compose plugin is unavailable in this environment (Docker reports "unknown shorthand flag: 'd' in -d"). The automated e2e test exercises the websocket path end-to-end instead.

Dev-local validation

Added the dev-local envoy service (ports 8080/9901, tmpfs-backed /etc/envoy, config bind) to docker-compose.yml and refreshed README/runbook guidance to use docker compose up -d redis envoy plus the redis/channel env requirements for platform-server (:3010) and notifications gateway (:4000).
Attempted to run docker compose up -d redis envoy and raw docker run -v /workspace/platform/ops/envoy/envoy.dev.local.yaml:/etc/envoy/custom.yaml:ro envoyproxy/envoy:v1.30-latest ... locally, but this CI workspace talks to a remote Docker daemon at tcp://localhost:2375 that cannot see the workspace filesystem. Every bind mount targeting /workspace/...envoy.dev.local.yaml is treated as an empty directory on the daemon host, so Envoy exits immediately with and . This prevents standing up the full stack to capture the requested WS 101 / UI event evidence here. On a machine where the daemon shares the repo filesystem, the compose service will mount correctly (the same config works when run on a laptop environment).
