Overview

Shared state passed across the walk.

Wraps the Qea::Database and provides:

  • ID-derivation helpers (xmi_id_for, end_xmi_id_for) backed by GuidFormat
  • delegated database lookups (objects, packages, attributes, etc.)

The Qea::Database already maintains its own lookup indexes (object-by-id, connectors-by-object, attributes-by-object, etc.). This class delegates to those rather than re-indexing — single source of truth lives on the database.
