Face-visibility gate v1: tier-1 = size/confidence/blur
pre-filter; tier-2 = obscuration check (blindfold/mask/occlusion/blur). Bad crops are
quarantined & flagged below — never grouped as people.
Gate applied — 2026-09-17 19:35: detections with no usable face (no_face) or an obscured /
occluded face (blindfold, mask, object, heavy blur) are quarantined, not clustered.
Shard-0002 ground-truth: Persons D+E+F+G from the prior build are quarantined; person
groups A/B/C below are the same-person matches that survive the gate. Source rows link to
the PikPak web viewer (share / drive page) rather than a force-download stream.
