1) Clicking the desktop Hub icon demanded the Hub password after any sign-out: api_logout set a hub_manual_logout cookie for 400 days and /auto-login honoured it. The icon is a trusted local entry point (its user is already signed in to the OS as free), so /auto-login now ignores and clears that legacy cookie and logout no longer sets it. Sign-out still destroys the session, and LAN clients -- who never get auto-login -- must still enter the password.
2) The Administrator (root) row in System Passwords showed the free/Hub hint verbatim. Root has no desktop or Hub sign-in and nothing refreshes its display copy, so it now gets a root-specific hint (sudo passwd root to set it; Hub Security Reset to make the tile show one again).
3) Brave prompted for a locked 'Default keyring' on Hub launch: the password cleanup removed configuration.nix's keyrings/default pointer and password-model.nix never re-seeded it, so gnome-keyring fell back to an encrypted keyring named Default. password-model.nix now seeds default -> login (the blank keyring) via tmpfiles, and its activation migration restores the pointer and moves any encrypted default.keyring aside (kept, never deleted).
The Hub launcher used an ephemeral /tmp profile deleted on exit, which
wiped the hub_manual_logout marker cookie. On reopen, /auto-login minted a
new session and logged the user straight back in without a password.
Use a persistent per-user profile under XDG_STATE_HOME and drop the
deletion trap so the logout marker survives close/reopen. Keep
--skip-origin-startup-dialog. Adds regression tests.
