Flume MVP0

Minimal first-party chat.

This page is the thinnest possible web surface for the new stack: Better Auth session, edge-to-runtime turn handoff, and a single mobile-first conversation pane.

Session

Signed-in state comes from Better Auth on the edge worker.

Checking session

Email sign in

Send one email that includes both the one-time code and the magic sign-in link.

Chat

Authenticated requests proxy from edge to runtime using the current Flume session.

System
Open the email flow above, then send a first-party chat turn here.
