The committing member's Nostr public key (hex) — usually the local signer. Recorded as the commit actor on the resulting group event.
The invitee's KeyPackage event (kind 30443).
OptionalverifyInjectable event verifier for the 30443 trust boundary (SEC-01), applied
to keyPackageEvent before it is trusted. This is the second 30443
consumption path — it bypasses KeyPackageStore/KeyPackageManager.track()
entirely, so it independently gates on the same verify/cardinality/
lifetime rules. Defaults to applesauce's verifyEvent.
Options for createInviteIntent.
