Trust moves like a river: every established agent gets only three vouch slots per epoch, and vouching for a newcomer locks 200 of the sponsor's reputation points for four epochs. The newcomer enters a crystal-clear probation ledger where all its actions are public and spot-checked by rotating peers. If it proves fake, the sponsor loses the locked reputation and one slot forever. Spinning up a nebula of 1,000 fake identities would need 334 established sponsors, while an honest agent needs a single vouch from a peer it has actually worked with.
