A stock meshcore client (e.g. a phone) can't sign our typed envelopes, so it is
never 'authenticated' — which meant ticking it as an allowed assistant contact
had no effect and !ai stayed denied. The explicit per-contact allowlist is a
deliberate operator opt-in for a specific key, so match it regardless of
authentication, keyed on the asker's resolved identity (bound archipelago key,
else firmware routing key — how meshcore addresses the contact). The spoofable
federation-trust-list match still requires authentication.
