"""Regression tests for the machine-dashboard multi-profile unification.

The dashboard is ONE machine-level management surface: config, env, MCP,
model, and chat-PTY endpoints accept an optional ``profile`` so the global
profile switcher can target any profile's HERMES_HOME. These tests pin:
reads/writes land in the REQUESTED profile, the dashboard's own profile
stays untouched, and the chat PTY env is scoped via HERMES_HOME.
