The sorting principle
A module's family is defined by what its output may touch.
The ecosystem's taxonomy isn't about what a workbook computes — it's about what its computation is permitted to do. Evidence-family outputs enter the record and inform interpretation, but bind nothing: a weekly EV read, a regime label, an efficiency grade. Authority-family outputs bind capital directly: a gate state caps tiers whether or not anyone agrees with it; a throttle resolution is the deployment envelope, not a suggestion. R&D-family outputs touch nothing at all until promoted: a scenario result, however brilliant, has no operational surface. The same metric can appear in all three families at different privileges — EV as evidence in the scorecard, as a tactical selector inside the throttle's authority chain, and as a sandbox variable in the lab — and the privilege, not the metric, is what the family system tracks.
