Specification

ModDef is defined by a versioned, normative specification. The Protobuf schema is canonical; the spec prose describes the semantics, validation rules, and conformance requirements every implementation follows.

• v0.4 (current): the current draft.

The spec is maintained in the moddef repository under spec/, alongside the schema (proto/), the conformance fixtures (fixtures/), and architecture decision records (spec/adr/).
