CrispASR regression-test fixtures

Reference-dump archives for the per-backend regression suite in CrispStrobe/CrispASR. See tests/regression/README.md in that repo for the full design.

Each <backend>/<sample-stem>/ref.gguf is the output of tools/dump_reference.py --backend <backend> against the corresponding source model, capturing the encoder output and a few intermediate stages (per-layer activations for some backends). The C++ runtime's crispasr-diff <backend> <gguf> <ref> <wav> reads exactly this format and reports per-stage cosine similarity vs the captured tensors.

Pinning to revision SHAs from this repo (in tests/regression/manifest.json's fixtures.revision field) prevents drift between commits — re-dumping with a different torch / NeMo / transformers version will not silently shift what CI tests against.

Why a separate HF repo

• The reference dumps are ~1 MB to ~50 MB each. Committing them into the CrispASR repo would balloon the working-tree size needlessly.
• Pinning to a fixtures-repo commit SHA is the cleanest way to decouple "we want to test against the same numbers as before" from the CrispASR git history.
• HF revision pinning protects against the "re-upload silently changes what users download" failure mode that motivated the regression suite in the first place.
