Reasoning
Each source is treated as a single opinion. For sources with multiple statements, I computed a per-source truth probability as sum of true confidences divided by the sum of all confidences. Source1 = 1.0, Source2 ≈ 0.786, Source3 = 1.0, Source4 = 1.0. The four sources combined yield an overall true probability of (1 + 0.786 + 1 + 1) / 4 ≈ 0.946. This strongly supports true for custom_reports.
