Module: Suma::LinkValidator::Step

Defined in:: lib/suma/link_validator/step.rb

Overview

Per-node-type navigation strategies for validate_deep_path.

Each Step handles one EXPRESS construct (entity, type, ...) and knows how to walk one path segment from it. The dispatcher in LinkValidator picks the right Step by handles?.

Adding a new navigable construct means adding a new Step class and registering it in REGISTRY — no edits to existing Steps or to validate_deep_path (open/closed principle).
