Jess builder

Tie a jess.

A jess is the strap on a falcon's leg; here it is the mandate a vault enforces on its AI. Draft one, see the strap, read the calldata, and replay real hunts against it.

Replay real hunts against your jess

Takes the last hunts a house tiercel actually attempted (kills and refusals from the log) and runs them through your clauses in the order the vault checks them. Slippage cannot be replayed from the log, so it is not judged.
