judge access

open hackathon demo for authenticated visitors

Anyone can explore this evidence and the landing page. Authenticated visitors can log in with Privy, view services, and trigger the unpaid x402 402 challenge. When live purchases are enabled, the bounded $0.003 wallet-activity check requires an authenticated identity plus an explicit start action; rejected requests receive an explicit not-allowed response and no money moves. The demo video shows the full write path.
