app/adapters/embedding/__init__.py

"""Frozen visual embeddings, and the identity index built on top of them.

Two modules, split along the line §6.4 draws:

- `backbones` — the ONNX adapters that turn an image into one unit vector, and
  the four specs §40.2 asks to be compared. Nothing in it knows what an animal
  is.
- `identity` — enrolment, matching, and the open-set decision. Nothing in it
  knows what ONNX is.

The split is not tidiness. The benchmark that chooses a backbone and the index
that serves a farm fail in different ways and are audited by different people,
and keeping the retrieval logic testable without a 837 MB artefact on disk is
what lets the open-set rules have unit tests at all.

Everything `adapters.embedding` exported before the split is re-exported here, so
`from app.adapters.embedding import DINOV3_SPEC` still resolves.
