Tests-025 (Conventions): Extracted the previously-duplicated NullDashboardEventBroadcaster into TestSupport/NullDashboardEventBroadcaster.cs (singleton Instance, private ctor). The two nested copies in EventStreamServiceTests and GatewayEndToEndFakeWorkerSmokeTests were removed; both files now use the shared type via 'using ZB.MOM.WW.MxGateway.Tests.TestSupport;'. The Server-041 regression test's ThrowingDashboardEventBroadcaster is intentionally left nested — single-file usage doesn't warrant promotion to TestSupport. The third copy in IntegrationTests/WorkerLiveMxAccessSmokeTests was handled by IntegrationTests-024 in its own commit. Tests-026 (Testing coverage): Added a new RecordingDashboardEventBroadcaster test double in TestSupport — a thread-safe (ConcurrentQueue<DashboardEventCapture>) recorder. New fixture StreamEventsAsync_PublishesEachEventToDashboardBroadcaster in EventStreamServiceTests pushes two events through the fake session and asserts the broadcaster received both with the correct sessionId and WorkerSequence. TDD red→green confirmed: the deliberately-wrong "Expected 3, Actual 2" red phase proved the recording fake was actually invoked by the production code path. Verification: 486/486 server tests passing (485 previous + 1 new). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
