Ask one or more typed questions about a piece of context through a System One decision endpoint (POST /v1/systemone). This is a decision model, not a chat model: it does not generate prose, it answers the questions you define.

Question types:

• choice: pick exactly one label from criteria (an object mapping label -> description).

• score: position on 2-10 ordered levels given as an array, 0-based. Returns score, legend, probabilities and confidence.

• noul: probability of yes, 0-1. criteria may optionally describe {true, false}. A value near 0.5 means uncertainty about yes/no, not medium intensity.

• box: region of interest as {top,bottom,left,right} normalized 0-1.

Batch independent questions in one call; questions cannot see each other's answers. The model cannot see your conversation or local files — put every fact it needs into state, and write each full judgment into instructions. Question IDs are only response keys.
