# Overview

Tags module — tenant tag-type catalog (under canonical companies/\{company}/config/tags/types namespace) plus entity-agnostic tag assignments, batch operations, and reports. POLYMORPHIC: any model using HasTags + registered in config/tags.php (customer, customer\_location, work\_order, equipment, lead, opportunity) can be tagged through this single API. Client always sends `entity_type` (stable string key) + `entity_id` (UUID); the server resolves to the morph class internally. Same tag cannot be assigned twice to the same entity within a tenant (unique index enforces idempotency).
