#2: Replace afterSequence+1<oldestRetained with overflow-safe oldestRetained>0&&afterSequence<oldestRetained-1 to prevent ulong wrap at MaxValue falsely reporting gap=true. #3: Add ReplayBufferCapacity and ReplayRetentionSeconds to EffectiveEventConfiguration and populate from EventOptions in GatewayConfigurationProvider. #4: Add four new SessionEventDistributorTests covering capacity=0 gap/no-gap paths and the ulong.MaxValue boundary case. #5: Update class-level <remarks> to describe the Task 3 replay ring buffer (capacity + age eviction, TryGetReplayFrom) rather than its absence. #6: Add O(n)-is-acceptable comment at TryGetReplayFrom linear scan. #8: Narrow no-replay 4-arg ctor to internal; InternalsVisibleTo already covers the test project.
