That specific technical point is trivial and is not worth discussing it. Of course you can „scan“ a data stream, but what’s the point if it doesn’t yield any meaningful results?

The only acceptable scanning process here is the one that produces only true positives, no collateral damage. This is what I call reliable.

well then reliability is impossible, you must accept errors
