Schemafier Build tool that extracts and reconciles documentation
Schema One concept's fields, caveats, evidence, and review state in YAML
Schemaset A versioned collection of schemas
Index Derived graph metadata and document embeddings for discovery

Core concepts — A docset becomes a reviewed schemaset, used directly or through a derived search index.

A field is an addressable fact or attachment point. A caveat describes a constraint or exception, with evidence and applicability. A concept groups a bounded subject, such as an API operation or command.

What to ship

Exact lookup needs the schemaset. Semantic search also needs a compatible index and query embedding provider. Format 0.2 schemas may reference a constraints/ directory that must travel with them.

Building from prose needs a generative model; reading the finished schemas does not. Keep source docs available because extraction can omit context.

Next: quick start or schema format.
