A/B validation
Checking your implementation by running the same work through a trusted reference and comparing outputs.
A/B validation pits your code against a known-good reference driver or library on identical inputs, treating any divergence as a bug in the newer side. In graphics this is how a from-scratch renderer proves correctness — its frames must match the reference's, ideally down to the bit. The reference acts as ground truth so you are not just testing against your own assumptions.
