Builders weigh Jev structured-decision model against graphical models, flag d-separation hurdle

- Jev (from typesafe) is a new model for structured decisions: given a question and a set of possible outcomes, it returns probabilities for each outcome.
- Developers are exploring whether combining Jev with graphical models could change how systems reason under uncertainty.
- The practical hard part, per jatingargiitk: the model can specify graph structure when given examples and variable names, but getting it to respect conditional independence without violating d-separation rules is much harder — the core correctness constraint of probabilistic graphical models.
