A dedicated public-API suite (boots the real server as a subprocess) so CI green proves
the token layer, not just the pre-existing tests:
- Partition firewall, derived from the SAME config/api-surface.js server.js mounts from:
every JWT-only router 401s a token; a public-surface snapshot fails if any router is
added to the token door; known-privileged routers asserted JWT-only.
- Threat model: role-strip gates, workspace-binding both directions (token ignores
X-Workspace-Id, JWT honors it), the scope ladder, the render bypass, token lifecycle,
and JWT no-regression.
- Device WS round-trip via socket.io-client (added as a devDep): valid device_token
registers + receives its playlist; wrong token rejected.
