Output Variance

Generative systems are stochastic, so repetition produces variation by design. In creative work that is a feature; in policy interpretation, eligibility determination or clinical guidance it is a defect, because two employees asking the same question in the same week should not receive materially different answers. Variance can be reduced by sampling settings, and eliminated only by not regenerating — serving a reviewed answer instead. Which approach fits depends on whether the question has one correct answer, and most operational questions do.

Centralpoint's governed cache removes variance where it matters: a reviewed answer is stored and served for equivalent questions rather than regenerated, so consistency and cost control are the same mechanism. Answer promotion makes this a deliberate editorial act with approval workflow and version history rather than an incidental caching effect.
