HeadmasterUI Settings

These are the settings you configure in the Headmaster desktop app itself. They control how the app looks, which models you connect to, and how the app talks to the runtime engine. Headmaster Settings is split into two areas, each with a clear purpose:
  • My Headmaster — the user-facing settings. No PIN required.
  • Headmaster’s Library — the advanced settings. PIN-protected, named after the wizard’s own study. Holds the things a regular user shouldn’t have to touch.

The PIN gate

The Library is protected by a PIN. The default PIN is set on first run — choose a 4-6 digit PIN. The PIN is:
  • Bcrypt-hashed locally. Not stored in plaintext.
  • Not recoverable. If you forget the PIN, the only reset path is reinstalling Headmaster. Your data (conversations, memory, files) survives a reinstall, but you’ll need to reconfigure the Library settings.
  • Rate-limited. Three wrong attempts trigger a 60-second lockout. Five wrong attempts trigger a 5-minute lockout.
Change the PIN in Headmaster’s Library → Advanced → Change PIN.

Settings modal vs. settings page

Settings can be opened two ways:
  • Settings modal — click the gear icon in the sidebar. A modal opens with tabs for each settings area. Good for quick changes.
  • Settings page — click Open as page in the modal header. Settings open as a full-page view. Good for long configuration sessions.
Both surfaces show the same options. The tabs in the modal match the full-page routes — any change in one is reflected in the other.
