- SA1019: math.Mul64/Add64 -> generic math.Mul/Add (ed25519fx, mldsafx, schnorrfx inputs; flow_checker; utxo_fetching); prefixdb.NewNested -> New (alias) - unused: DELETE dead codecVersion const (last codec reference in utxo — full ZAP native now), isSortedAndUniqueOrdered (root + secp256k1fx), mldsafx Keychain.get, and all 6 redundant TransferOutput.isState() markers (the embedded verify.IsState already provides State membership) - QF1008: drop embedded-field selectors (utxo_wire, ed25519fx, nftfx, propertyfx + tests); ST1005: lowercase Schnorr error string Behavior-identical; 11/11 packages pass.
