Overview

Unified metadata extractor for all flavors.

Uses the self-describing type interface (identifier_types, all_typed_stages, locate_type, locate_stage) on each flavor module. No Scheme dependency (Scheme class removed).

Open/Closed: Adding a new flavor requires only adding it to Exporter::FLAVORS. Single Responsibility: Extracts metadata from flavor modules into value objects. Single Source of Truth: Each identifier class IS the type definition.
