has category

Places the subject in a product-level browsable category for user-facing discovery and filtering. Less formal than `has type` (which asserts a taxonomy classification) and more curated than `has tag` (which is free-form).

enshrined Identity/Classification hasCategory

Enshrined — the object model is decided and the ID below is what every conforming app and the contract resolve.

Identity

A predicate is itself an atom. Its ID is derived from these exact bytes — the same value in your app, in anyone else's, and onchain.
