Reasoning

Under the REPORTED_ALLEGATION RULE, this event is scored on the underlying alleged act (sexual assault of a minor at a sex party), not the act of reporting or the source's characterization of veracity. The alleged conduct-multiple adults at a sex party involving a 13-year-old-constitutes a primary trafficking signal. Confidence is moderate-to-high because the allegation is explicit and specific about victim age and context, though the source's 'fabricated' framing introduces some credibility uncertainty that prevents higher confidence.
