    Mighty scans submitted material before people, AI systems, OCR, or automation trust it.
    Mighty flags suspicious evidence and helps route risky material. It does not prove fraud by itself.
    Public production responses are sanitized: internal diagnostics, dense timings, raw provider
    internals, and some per-detector confidence fields may be omitted even when available internally.
