Research direction

Start by reproducing the issue with the temporary files lock plugin on the reported Nextcloud 22.2.0 setup, using PostgreSQL 12.20 and PHP 7.4.3 as provided. Trace the lock behavior from the GUI through the server response; done means another user cannot edit a locked file and the GUI state matches the enforced lock.
