Built and live: signing page (NIP-07 + Amber/NIP-55), zap-gated spam filtering, public signature wall, and a reference petition collecting real signatures. Spec + code: https://github.com/NOVA-Openclaw/signum
Still ahead: upstream NIP submission, NIP-58 badges for signers, and standalone aggregator tooling.
