Neither InsightFace export parses as shipped -- SCRFD fails at its input
node, ArcFace at the first Conv -- which is the same wall dr-segment hit
on YOLO's dynamic export. Both load cleanly with the input dims frozen,
so the pure-Rust runtime holds for the face pipeline too.
tools/fix-face-model-shapes.sh does the freezing, and exists so the
artefact is reproducible rather than a binary someone once produced. It
takes two forms because the two graphs need different ones: ArcFace's
batch is a named dim_param, SCRFD's H and W are dynamic but unnamed.
Also notes YuNet loading with no intervention, which matters for the
licence question in faces.md 2.3.

FR-CULL-8..12 specify the subsystem in terms of "a 512-dimension embedding
from a stated model" and stop there, because D13 was open. This names the
models, and grounds them in the measurements and the working C++ pipeline in
../scene-actor-extraction rather than in a literature reading.
The licensing half of D13 stays open, but with a route through it: the
InsightFace weights are non-commercial and cannot be committed, so the app
ships the code and the user fetches the model. faces.model_id already makes
that a survivable choice.
