Overview

Read-only comparator for the portable schema wire format. This class is intentionally separate from import_schema: a preview must not run validations, callbacks, jobs, conversions, or a dry-run transaction. Each incoming entry must carry the exact entity_type/scope/parent_scope identity declared by the envelope; preview does not retarget entries. rubocop:disable Metrics/ClassLength -- the validator and comparator form one small, private implementation behind the single preview API.
