source/core/schema/datum_relation_spec library

Typed relation descriptors — the no-codegen way to declare, load, and fetch relations without stringly-typed names, foreign keys, or casts.

A DatumRelationSpec binds together, at the type level, everything a relation needs: the owning entity E, the related entity R, the relation name, and the foreign key as a DatumFieldSpec — so the same declaration that powers queries and auto-migration also anchors the relation graph, and a typo in any of them fails at compile time.
