blank (63,071 docs) + blank.photo (4,288)
after
Mostly mis-bucketed image.photos — 75/95 in blank sample were small photo centered on white page
rationale
v1 blank-detection appears to be pixel-density based (high white-pixel ratio → blank), which mis-classifies any photo with a white background or small photo on white page. Subagent #4 found 75/95 = 79% of "blank" sample docs were actually image.photo. Extrapolating: ~50K of the 63K blank docs may be misclassified image.photo, including a "Caribbean island construction" photo dossier of ~15+ docs in EFTA0113xxxx–0118xxxx range that has investigative value.
