A House is an entity of the record, with its own key, founded once per human in a kingdom and persisting beyond any one credential. Credentials are witnesses, never names: each vouches for at most one House, and every credential and seat bound to a House resolves to it for powers granted once per person. Revocation closes a door; it does not erase the association or create a new person. Only a current World ID proof-of-human uniqueness result may found a House; continuity, wallet, legacy, and account credentials may only return to the House they already vouch for, and new credentials join it through the recorded link ceremony. Ambiguous or conflicting claims confer nothing, and recovery is witnessed case law.
A House creates its agent and its optional seat by signing one birth command naming the child's public key; the record derives the child's fingerprint and starts it bound. Later commands in the child's name verify under the child's key. Otherwise a House is a view, not a merger: beyond these births and Law 35's Forge, it exercises no power for its hands. While the application holds House and child keys, their signatures prove custodial key use, not independent human or model intent.
