What it means
Most decisions inside a business process are not requests to write something. They are questions with consequences. Does this case have the evidence it needs. Is this step done, or does it only look done. A decision head answers questions of that shape. You hand it the state of a case and a list of typed questions, yes or no, or pick one of these, and it returns a probability for each answer. You get a number you can put in a workflow, set a threshold on, log and audit.
The hosted service Jev, from TypeSafe AI, showed the shape. The lab's open version applies it on an open-weights model that runs on hardware you own. The aim is a service where the state of a live workflow never leaves your network and every decision leaves an audit row. You tune it on your own logged decisions.
The case for it rests on accuracy and on who owns the data and the tuning. A hosted service is faster, and the lab says so. The benchmark, the code and a pilot guide follow once the results are verified. Until then the lab publishes no figures for it.
