## About

A team makes a hard technical decision with AI, and keeps the receipts.

Opens a seeded demo workspace at http://localhost:8000 , signed in with one click. No account, no config. Prefer to run from source? git clone this repo and run docker compose --profile demo up instead (see Docker below for the non-demo path).

One click drops you into a workspace already mid-decision: a channel conversation, a branch with two specialist outputs to compare, and a published Decision Brief with its evidence chain intact. No API key is configured for this recording, so the specialist outputs and the brief show the conspicuously labelled SIMULATED workflow output described above; the collaboration mechanics are the same either way.

Modern AI tools are single-player: one human, one chat, one context. Real work happens in teams. XYZZY lets multiple humans and AI agents share a room: a common event history, artifacts, tasks, and decisions, persisted in SQLite with WebSocket-driven real-time sync. Agents branch out in parallel, a human selects or excludes what comes back, and the room publishes an immutable Decision Brief with the evidence chain behind it.

Governed. Actions wait for human approval before they execute. What an agent may do is re-read from the room's own state at the moment it acts, so leaving a room or losing access takes effect immediately, mid-task.
