Description

A hunch via code inspection:

In state 5 of the egressConsumer workerFSM, a write error will correctly close the WebSocket, exit the state, and terminate the worker's goroutine -- but it will leak the goroutine we fire off to execute the read loop.

T/F?

Research direction

Start in client/go/egress_consumer.go at the state 5 write-error path around line 105 and the read loop launched around line 72. Trace the workerFSM and read-loop lifecycle, then add coverage for a write error. Done means the test establishes whether the read-loop goroutine is left running after the WebSocket closes.
