The ported client's + `ConnectAsync` is one-shot and there's no health monitor. *Mitigation:* the Tier C + supervisor on the Proxy side (CircuitBreaker + HeartbeatMonitor) restarts the whole Host + process on liveness failure, so connection loss surfaces as a process recycle rather than + silent data loss. **Reconnect-without-recycle is a v2.1 refinement** per `driver-stability.md`. + +### Medium + +3. **`MxAccessGalaxyBackend.SubscribeAsync` doesn't push OnDataChange frames back to the + Proxy.** The wire frame `MessageKind.OnDataChangeNotification` is defined and `GalaxyProxyDriver` + has the `RaiseDataChange` internal entry point, but the Host-side push pipeline isn't wired — + the subscribe registers on the COM side but the value just gets discarded. *Mitigation:* the + SubscribeAsync handle is still useful for the ack flow, and one-shot reads work. **Push + plumbing is the next-session item.** + +4. **`WriteValuesAsync` doesn't await the OnWriteComplete callback.** v1's implementation + awaited a TCS keyed on the item handle; the port fires the write and returns success without + confirming the runtime accepted it. *Mitigation:* the StatusCode in the response will be 0 + (Good) for a fire-and-forget — false positive if the runtime rejects post-callback. **Fix + needs the same TCS-by-handle pattern as v1; queued.** + +5. **`MxAccessGalaxyBackend.Discover` re-queries SQL on every call.** v1 cached the tree and + only refreshed on the deploy-watermark change. *Mitigation:* AttributesSql is the slow one + (~30s for a large Galaxy); first-call latency is the symptom, not data loss. **Caching + + `IRediscoverable` push is a v2.1 follow-up.** + +### Low + +6. **Live MXAccess test `Backend_ReadValues_against_discovered_attribute_returns_a_response_shape` + silently passes if no readable attribute is found.** Documented; the test asserts the *shape* + not the *value* because some Galaxy installs are configuration-only. + +7. **`FrameWriter` allocates the length-prefix as a 4-byte heap array per call.** Could be + stackalloc. Microbenchmark not done — currently irrelevant. + +8. **`MxProxyAdapter.Unregister` swallows exceptions during `Unregister(handle)`.** v1 did the + same; documented as best-effort during teardown.
