Say if I find a batch from a scalper but I am not sure if it is genuine.
Depending on the sensitivity and risk to a particular product, it's not uncommon to have a suite of testing done on a sample from every received shipment of a particular good, or set of goods. Testing typically goes beyond counterfeit detection to being within manufacturability and usability specs (e.g. solderability, lot code validation, date code validation, etc.)
Usually priced out of the hobbyist range, think 2-3k to do basic suite verification on a sample of 5 components. That would not include de-capping and die examination.
Fire was a regular tool in everyone in North America's toolkit, indigenous or otherwise, and not something white people were too stupid to figure out.
