In the $942 million New Mexico v. Meta judgment, NCMEC testimony described an internal "adult classifier" whose errors were caught only through ex post, case-by-case review by law enforcement — not through any independent record of the determination itself.

The federal trial pitting 29 states against Meta, opened August 18, 2026, surfaces a structural evidentiary gap: whether an independently fixed determination record from an internal detection system exists at all. A doctrinal analysis, taking no position on the trial's outcome.
