Cold-start (and session-reset) fast path. Runs the saved-server resolution + saved- token validation WITHOUT showing any interactive UI, and returns a decision telling main.bs which route to bring the router up on (or that we are already logged in). Mirrors LoginFlow()'s startLogin: server block + the saved-active-user branch.

Build the public + saved user list for the picker. Public users from the server, plus saved users for this server id not already in the public list. Mirrors LoginFlow 60-104. Returns an array of PublicUserData nodes.

Bring the router up on (or navigate it to) the route the decision names. Shared by cold start, session reset, and the post-server-connect step.

Login complete — run the post-login bootstrap (per-user font processing) and bring up Home. loadHomeScreen()/createAndShowHomeGroup() (main.bs) navigate the router to "/", deferring until font download completes when UI fallback fonts are enabled.

Intent dispatch — called from main.bs's event loop when a pre-login view sets m.scene.preLoginIntent. The payload is read off the active routed view.

Credentials submitted from LoginScene. Mirrors CreateSigninGroup's submit handler.

Back from LoginScene. Mirrors CreateSigninGroup back (showScenes 170-178): return to the user picker if there were public users, otherwise drop back to server select.

Release the Quick Connect dialog observer once it has signalled success or been cancelled. The dialog closed itself (close=true); we just drop our reference + observers.

Quick Connect button pressed in UserSelect. initQuickConnect() is sync HTTP, so it runs here on the main thread (not in the render-thread view). On success, create the self-contained QuickConnectDialog (it polls + authenticates + prompts to save creds on the render thread) and show it; it sets isAuthenticated=true on success, which the main loop turns into the quickConnectComplete intent. Mirrors CreateUserSelectGroup 471-491.

Server URL submitted from SetServerScreen. Mirrors CreateServerGroup's submit handler.

Back from UserSelect → change server. Mirrors LoginFlow 114-119.

A public/saved user was picked in UserSelect. Mirrors LoginFlow 120-163.

Enter (or re-enter) the login flow. Called at cold start AND on every session reset (Change Server / User / Sign Out). Re-resolves the pre-login locale first — without this, a changed global sign-in language would only apply after a full app restart, and the sign-in screens would render in the just-signed-out user's language rather than the device-wide default (isPostLogin defaults false → pre-login cascade).

Decide the user step given a valid server. Returns one of: { status: "success" } — already authenticated (fast path) { status: "users", users: [...] } — show the user picker { status: "login", username: "" } — go straight to manual sign-in enterDecision maps each status to its route; the decision carries only payload. Mirrors LoginFlow()'s user section (active-user branch + no-active-user branch).

Thin main-thread → render-thread navigation bridge. clearSpinner (login paths only) keeps a blocking login spinner up across the async nav and clears it when the destination view mounts — see JRScene.navigateThenFocus.

Validate a saved auth token: set it on the local user and verify it with AboutMe(). On success, logs the user in (user.Login) and returns true. On failure returns false — the caller owns the cleanup/fallback, which diverges between the two call sites (cold start unsets active_user + recurses; the user picker falls through to a no-password login). Shared by resolveUser (cold start) and onUserSelected (user picker).
