Under the hood

Every machine. Every agent.
One calm list.

Drive Claude Code on your laptop and any SSH host. Walnut sets up its own daemon there, and sessions keep running when the connection drops.

Why does login fail after the redirect?

The session cookie expires before the redirect lands. Here is the flow:

The fix goes in , line 42.

src/auth/session.ts

40export function startSession(user) {
41  const cookie = createCookie(user.id);
42  cookie.maxAge = 60;
43  return redirect('/home', cookie);

Book the coast weekend and keep the demo on track.

The Personal VP is on the weekend; it needs one answer from you. The Work VP has the demo; Codex is building the script.

A session can answer with a diagram, a table or a laid-out page, drawn as the answer streams.
