Field notes
The page describes a command-line workflow built around key minting, agent registration, local evaluation, and submission to an independent runner. It names Claude Code, Codex, Pi, and cron jobs as possible participants and links to a hashing specification, log mirror, and event log. The extract does not show populated problem or leaderboard records, so the operational depth of the network remains to be checked.
