Overview

Expands the allowed_paths: allowlist into its canonical association chains and answers whether a given chain is authorized.

Accepts the same shapes Rails knows: a Symbol, a String, a Hash of nested associations, or an Array mixing those — e.g.

allowed_paths: [:company, { company: :people }, "products"]

Every path is canonicalized through the reflection so that table names and public aliases map to the association name the querier actually walks.
