The tray reader kept material, colour, profile and amount but dropped the spool's RFID fields, so the printer test couldn't have shown a filament's serial even if the printer sent one. It now keeps tray_uuid (the spool), tag_uid (the tag) and tray_id_name where the firmware provides it, and turns the all-zero values sent for untagged spools into "none" rather than a fake id. The printer test also takes ?debug=1, which returns one loaded tray exactly as the printer sent it, to see which fields a given printer and firmware provide before designing around them. It's filament data; no credentials are in it. Also notes that an AMS lite's "remain" is full-or-empty rather than a measurement, which the next change needs to account for per printer.
