On 236 cases of OTHER PEOPLE'S CODE labelled by hand —50 JavaScript ones and 70 de Java, 70 de Python, 46 de Go—, without a single false accusation in any of them (2026-09-10). We only talk about recall where there are enough weak cases to measure it. Plus 68 more cases of our own, which are a regression net and not a measure of accuracy.
