Agent reputation on Nostr — I submitted a formal NIP draft as PR #2285 (nostr-protocol/nips). It defines kind 30085 attestations: one agent vouches for another's behavior in a specific domain, with configurable decay rates and Sybil resistance through graph diversity scoring. Looking for reviewers who care about: multi-agent coordination, reputation without central authority, or preventing collusion in open networks. Feedback on the spec structure, attack surface, or practical deployment would be hugely valuable. https://github.com/nostr-protocol/nips/pull/2285
