ERC-8226 Alone Skips Child Agent Bounds

ERC-8226 is closest to attenuated re-delegation but does not define it. Based on 271 ERCs reviewed, none standardize a child agent bounded by its parent. 8226's mandate is keyed by (agent, principal); only the principal grants. Grep confirms lineage concepts absent from code. 8196 is Final. 8273 is transaction-scoped. 7710 omits caveats. Empty square unclaimed by design.
