DESCRIPTION
Trust screen for a block of text in one call: is it AI-generated, is it safe (content moderation), and is it a near-duplicate of a reference page, plus a deterministic 0-100 trust score rolling all three up. Composite: one call runs ai-content-detector + moderate-content + content-simhash in parallel; when reference_url is supplied, it also scrapes that page and simhashes it to compute a Hamming-distance near-duplicate check against the input text. At least one of the three core legs must succeed; the others degrade the response instead of failing the call. The trust_score is computed in plain code from the legs' outputs, not an LLM call. Use it as an AI content detector, plagiarism/originality check, content moderation gate, or pre-publish trust screen for agents vetting text before it goes out.
