ISessionManager.ReadEventsAsync had zero production call sites: the worker event channel is drained once by GatewaySession.MapWorkerEventsAsync (the distributor pump), and every consumer — gRPC subscribers, the dashboard mirror, the alarm monitor — attaches to the distributor. The interface member, SessionManager's forwarder, and GatewaySession.ReadEventsAsync are gone; IWorkerClient/WorkerClient.ReadEventsAsync is untouched, it is the live worker-channel claim. No test was removed or rewired: nothing invoked the member through the interface. Nine ISessionManager test fakes carried a required-member stub (seven threw NotSupportedException or yielded nothing; EventStreamServiceTests and GatewaySessionDashboardMirrorTests forwarded to the session; the two MxAccessGatewayService fakes yielded their Events list) — all nine stubs were deleted. The MxAccessGatewayService suites' streaming tests already run through FakeEventStreamService, which reads the same Events list, so their coverage is unchanged; only the now-inaccurate doc comments on Events / LastReadEventsSessionId were reworded. The MapWorkerEventsAsync comment no longer describes a twin to keep in step; it now states the single-reader claim directly. docs/Sessions.md drops ReadEventsAsync from the SessionManager member list and from the Run-state prose. The 2026-08-15 deferred-remediation as-built note records the removal.
