## Abstract

A positive practice instrument for concise, inspectable, revisable work. It reads self-declared tags and evidence labels against a versioned practice registry and returns one of four statuses over declaration coverage. It measures whether the evidence a practice asks for was declared — never whether the work is true, good, or permitted; an ALIGNED reading authorizes nothing.
