Overview

Validates that every cross-entity reference in a Database points at an entity that actually exists. Single source of truth for both Database#validate_references and the unitsdb validate references CLI command.

ReferenceValidator    — public façade; returns a Result
IdRegistry            — builds {type => {key => path}} from db
ReferenceChecker      — walks each reference kind
LookupStrategies      — pluggable "is this ref valid?" predicates
