The page bootstrap currently injects JSON.stringify(clientData) directly into a <script> tag, so a crafted room/loc value containing </script> can break out of the assignment and run arbitrary JavaScript in the viewer’s browser. The previous implementation explicitly escaped < before embedding JSON; this needs to be restored here to prevent script injection via URL parameters or sheet data reflected into clientData.

This loop writes each row immediately after validating that one row, which means a later invalid update causes the function to return an error after earlier rows have already been modified. For payloads with multiple updates, this creates partial saves and data inconsistency despite a failed response. Keep validation and mutation in separate passes so no cell writes happen unless the entire payload is valid.

statusClass_ can receive canonical values like Good from normalizeStatus_, but the subsequent checks compare against lowercase literals (good, low stock, etc.), so recognized statuses fall through to status-default and lose their intended visual severity styling. Normalize to one case before the comparisons (or compare against canonical strings) so status pills render correctly.
