Amendment
Doctrine and SOP changes need Custodian approval but no amendment — unless they cross the infrastructure boundary, in which case a companion Constitutional amendment is required.
A Custodian-drafted amendment takes effect when the Tech Board ratifies it; a Custodian objection suspends it and sends it to the Economic Group, whose decision is final and not vetoable. The delegation reaches the governed corpus only — never the Custodian’s own private node.
