Why replication matters

An expert who relies on a tool they cannot check is exposed on cross-examination. IPLYR's output is meant to be re-run, so an opinion rests on a measurement the expert has verified independently.

What a challenge usually targets

Extraction evidence is typically attacked on how many attempts were made, what counted as a match, and whether a similar rate would appear on text the model never saw. Reports are written with those challenges in mind and say plainly where a question remains open.
