Verify a ~handle
alter_verifyRead-onlyIdempotent
Check whether a ~handle is known to the ~alter identity field. Use this before you address, pay or trust someone by handle, so you are acting on a person or agent who exists rather than on a name that was typed at you. Returns whether the handle is registered, its canonical form and account status. Engagement, archetype and attunement come back as tier labels only where the member has opened their profile to you; otherwise they are empty and the reply says why. Listed free at L0; calling it needs a credential, which an agent can mint for itself with register_autonomous_challenge then register_autonomous.
