Error message

EventBus emit failed for ${eventName}: ${err instanceof Error ? err.message : err}

What it means

Log warning in dispatchInbound: emitting the typed inbound event (federation:inbound:<type>) on the integrator's EventBus threw; the emit failure is deliberately contained so it cannot crash the inbound message receive loop.
