+		// was stored with the inbound tx sender (CEA executor) as the sender field.
+		// The UEA contract's executePayload calls the verifyTxHash precompile with
+		// id.owner (UEA owner), causing a sender mismatch and verification failure.

+		// origin chain (e.g., eip155:11155111). This chain mismatch caused the
+		// precompile lookup to fail.
