A read-only flag can be set on a script execution using the public API (Public API). When this flag is set to true, all pages are immutable. A user, most likely a caseworker, can review the script by using the navigation buttons and the sections panel, without the ability to edit any information.
When the read-only flag is reset to false and a script execution is resumed in editable mode, the current page will be the page the editing user was on previously, not the page the reviewing user last visited.
