Runs the agent-identity rules for Google RBM: display name, description, colour contrast, logo and hero asset specifications, the contact details shown in the agent card, and the verification contact Google emails — without which brand verification cannot start at all.

Checks are free and unlimited and never consume allowance. Pass the subject as a stored-resource reference OR as an inline payload — never both for the same subject. With options.wait: true the connection is held until the verdict is ready; otherwise a fast check arrives already passed/changes_required and a slow one arrives processing for polling. options.include_website_review triggers a real crawl and is subject to a per-account daily quota.
