Reverts 53f7cdf and e92d22d. The floor those added sat on
Detector::detect, refusing any buffer under 1025px on the reasoning that
a small buffer finds no faces. That reasoning does not survive §4.1:
the detector letterboxes every input to 640x640, so a face occupying 2%
of the frame presents at 12px to the model whether it is handed a 1024px
buffer or a 6000px one. Detector input is precisely the quantity that
does not matter.
Worse than merely useless, it blocks the design FR-CULL-8 now specifies,
where the detector is deliberately fed a downscale and the crop is taken
from the native render. A guard on detect() rejects exactly that call.
What the measurement actually supports is a floor on the *crop* source,
which is where resolution converts into embedding quality, and which
faces.crop_px already records: 47% of the reference library's faces were
upsampled to reach 112x112. That floor is a separate change against the
native-resolution path and does not belong on the detector.
The 23x faces-per-image gap by source_edge that motivated the original
commit is kept in faces.md §7b, restated as the unexplained observation
it is rather than the causal claim it was written as. V12 stands: those
runs cropped at 1024 whatever detection did, and that is reason enough
to look at them again.
