NIP-3C: OTS Handling Policy for Nostr

Behavioural NIP that complements NIP-3B. Defines kind:30041 โ€” an addressable replaceable event whose content is a JSON document declaring how the publisher creates, stores, strips, keeps, and serves OTS proofs. Five orthogonal rules + retention bounds + cooperative-upgrade flags + NIP-44 encrypted fields.

Bitcoin-anchored time-attestation protocol for Nostr events. Binds an OpenTimestamps proof to the event signature, defining the leaf digest, two on-wire transports (ots/oldots sidecar field + kind:1041 beacon), verification rules, and NIP-44-encrypted private beacons.
