What this site actually exposes
Sign-in opens /console: per-user field notes on architecture nodes, a consent-gated model chat, and the sealed audits of that chat. Model replies are sign-in-gated, rate-limited per user, and not an Abbey session.
Every per-user server function runs behind the session middleware and scopes its queries by the signed-in user id, never an id sent by the browser. Without a session the console redirects to sign-in. On the static GitHub Pages build these surfaces render a server-only notice instead.
The surfaces below are everything the server exposes. There is no hosted assistant API and no platform SDK.
