WHY IT NEEDS A POLICY

Why lexq_domain_templates_apply needs a policy

This tool creates new domain templates at the tenant level, which is a write operation that modifies the business rules infrastructure. The scope is tenant-wide ('current tenant'), making unauthorized application a significant risk. While not destructive (the template could theoretically be removed), the blast radius is high because domain templates likely govern critical business logic across policies and rules.

From the tool's definition Tool description states 'Apply a domain template to the current tenant. Creates the template' — the verb 'Apply' combined with 'Creates' indicates irreversible creation of domain-level configuration that affects the tenant.
