The origin was iterative. Éssert had eighteen solutions that needed migrating, and no way to produce the next hundred without hiring the next hundred people. That reframed software itself — not as projects sitting in a queue, waiting their turn, but as titles that either exist on the shelf or don’t yet.
The ambition became the ability to produce a hundred of them. Éssert started there, structured on Goldratt’s assembly line: throughput governed by constraints, not effort. An assembly line doesn’t go faster by working harder — it goes faster by finding the constraint and governing it.
ZHC applies that to software production. Humans hold two constraints: approve the brief, approve the merge. Agents run everything between. That’s the whole idea. Everything else on this site is that idea, applied to a different question.
