USR369 asked to go over the open EXEC_OPEN files and update the token in them. Found: every one of the 11 systems current active EXEC_OPEN_*_S.txt file had the OLD retired token hardcoded literally in a TOKEN section (separate from the [TOKEN] placeholder used elsewhere in the file for the actual open-session flow). Backed up all 11 (one BACKUP.php call per owning system), patched (literal swap old->new), redeployed, verified all 11 clean live. Packaged all 11 updated files into a ZIP and delivered to USR369 directly.
