A public-policy understanding engine. It measures understanding as a fraction — the share of the questions that matter which are answered by trusted sources — and names the holes instead of rounding up. Reject a claim below and watch every view recompute. No page reload, no server, no model call.
Causal edges read from the corpus. Solid = confirmed by a source; dashed = an inferred reading, still proposed. Bar = confidence. Every edge opens to the evidence it rests on.
