What was reused
Kind 39697 schema version stays "1". New optional tags on a web observation are role, proto, and a normal NIP-01 a tag that points at 39698:pubkey:id. Old clients ignore them. NIP-90 DVMs stay on kind 31990.

| 32267 | NIP-82 software app | Package metadata for installable software. Not an MCP listing. |
