spec-spine-types
Typed data substrate for spec-spine:
DTOs, the spec frontmatter grammar, the Config model, the authority-unit and
typed-edge grammar, schema-version constants, and the stable Error enum.
This crate is plain data: owned, serde-serializable types with no lifetimes,
generics, or trait objects at the public boundary, so it can back both the
spec-spine-core engine and future FFI bindings (napi / pyo3 / cgo).
See docs/design/00-architecture.md in the workspace for the full design.
