"""Regression coverage for issue #1700 parallel profile switching.
|
|
|
|
A WebUI profile switch uses cookie/thread-local profile state, so it should be
|
|
allowed while another session is streaming. Only process-wide profile switches
|
|
must remain blocked because they mutate global Hermes runtime state.
