Verified equipment record PT-104

Linked incident: INC-PT104-001 · Blue Ridge Lab · PT-104 Pump Skid · PT104_Lab_PLC (sample)

This is the public sample of the equipment record a pilot cell builds up over time. Every fact below is drawn from the PT-104 sample fixture; fields the fixture does not support are marked unknown, never guessed. Customer records are authenticated and tenant-isolated; this page is the sample only.
