 36// Identity note: access control is keyed by the immediate caller via
 37// cur.Previous().Address() — the statically-scoped realm handle, not the
 38// stack-walking tx-origin. For a direct `gnokey maketx call` this resolves to
 39// the signing EOA (matching the address-keyed access list); a call routed
 40// through an intermediary realm is identified as that realm and denied unless
 41// explicitly granted. This is the phishing-resistant pattern recommended in
 42// gno-interrealm.md, and avoids the chain/runtime/unsafe primitives entirely.
