AI can prepare a people decision. It cannot own it. Ten builds in the order to build them, each with its map row, its mode, its difficulty, its deploy estimate, its impact and its decision owner. This is the build sequence out of the HR AI Stack: which agent to build first, the week each one lands in, the month-one cost stated out loud, what the first ten leave out on purpose, and the eleventh implementation with the date that funds it: for employers with 150 or more workers, the first pay transparency report under Directive (EU) 2023/970 is due 7 June 2027 and it reports calendar year 2026. Not a teaser with the answers removed. The first week is chosen to name nobody: two agents that report on populations and need no policy library at all, so you find out how your own build behaves before an output ever concerns a person. Free, no email required beyond the download. If you want the fences, the fixtures, the answer keys and the 68-scenario test protocol behind these ten, that is the HR AI Stack. Practitioner guidance, not legal, employment-law or medical advice.
