The desktop remote-gateway settings now auto-detect whether a gateway
authenticates with OAuth or a static session token and present the
matching UI + connection mechanism.
Detection: an unauthenticated GET {base}/api/status reads auth_required
(true => OAuth, false => session token); /api/auth/providers supplies the
provider label. The settings UI debounce-probes the entered URL and shows
either a 'Sign in with <provider>' button or the session-token box.
OAuth connection mechanism:
- REST is authed by the HttpOnly session cookie held in a persistent
Electron session partition (persist:hermes-remote-oauth); main-process
REST routes through electron net bound to that partition so the cookie
attaches automatically.
- Login opens a BrowserWindow on {base}/login in that partition and
resolves once the hermes_session_at cookie lands.
- WebSocket upgrades use a single-use ?ticket= minted at
POST /api/auth/ws-ticket (the gateway rejects ?token= in gated mode);
getGatewayWsUrl() re-mints before every (re)connect since tickets are
single-use and short-lived.
- Missing cookie / 401 surfaces needsOauthLogin to prompt re-sign-in
(Nous Portal contract v1 issues no refresh token).
Local and token modes are unchanged.
Pure helpers (URL normalize, ws-url token/ticket builders, auth-mode
classify/resolve, cookie detector) are extracted to a standalone
connection-config.cjs (no electron import) and unit-tested with
node --test (26 tests), matching the backend-probes.cjs pattern.
