sim-relation-schema
Provider-neutral relational schema intent and normalized observations of live provider catalogs. Construction validates names, domains, constraints, generated/default expressions, foreign keys, and view dependency graphs before a codec or storage provider sees the schema.
The logical and physical records deliberately have different types and Datum
tags. Both identities use sim-relation-core's canonical kernel-backed digest.
The crate uses the rustdoc recipe-policy exception: exact store-schema
fixtures are checked by rustdoc and integration tests, so it intentionally
ships no recipe directory.
