Read usage rules

No codeExplain how to obtain a confirmation code without implying that a request exists.

VerifiedShow the authenticated request timestamp and the processing deadline.

InvalidReject an unverifiable token and never display a false received status.

UnavailableFail closed when the signing secret or service dependency is missing.

Legal meaning is owner-controlled. Design changes may alter structure and typography, never obligations.
Every repeated state has a text label, keyboard focus and a mobile layout.
Tables scroll inside their own boundary. The document viewport never overflows.
Print removes navigation, preserves provenance and avoids orphaned headings.
Production callbacks reject unverified signatures and missing secrets.
