NodeInfo

The federation document GET /nodeinfo answers: what software this instance runs, what it speaks, and how much it is used.

NodeInfo is a cross-project schema — Mastodon, PeerTube, Forgejo and the rest of the fediverse all serve it — which is exactly why it is modelled here rather than handed back as a string: a caller reaching for nodeinfo is trying to branch on software.name or on protocols, and doing that against raw JSON puts the schema's spelling into their code instead of into this library's.

'''The wire keys are camelCase, not snake_case.''' openRegistrations, localPosts, activeHalfyear — this is the one model in the library whose spellings are not Forgejo's own, because the schema is not Forgejo's own. Rule 4 of com.worxbend.codeberg4s.codec.WireConventions still holds: each of those names is written exactly once, in the DTO's reader.

'''Derived from spec/swagger.v1.json's NodeInfo definition, not from a captured response.''' golden/MANIFEST.md records that GET /nodeinfo answered 404 on codeberg.org with a '''plain-text''' body, so no fixture exists and a caller must expect this endpoint to be absent on a deployment that does not federate.

'''metadata is not modelled.''' The schema types it as a free-form JSON object, and the domain module depends on nothing beyond the standard library, so there is no honest representation for it here — a Map[String, String] would silently drop every non-string entry. Forgejo populates it with an empty object.
