# Model parameter similarity experiments

Bounded, inference-free analysis of official unquantized model weights. The first experiment
is **Qwen3.5-2B**. Model weights are downloaded and analyzed on the authorized remote host,
then deleted after archived results pass validation. No model weights are committed here.

- `pilot/download.py`: revision-pinned official checkpoint download and verification.
- `pilot/tensors.py`: memory-mapped safetensors/BF16 reader and metrics.
- `pilot/analyze.py`: bounded tensor/block search, exact verification, representative groups.
- `pilot/plot.py`: scientific PNG/PDF/SVG figures and report from saved data.
- `pilot/validate.py`: result/group validation, checksums and guarded weight cleanup.
- `pilot/audit.py`: finite-metric checks, test evidence and archive provenance.
- `pilot/run.py`: one-model supervisor with bounded download wait and analysis timeouts.
- `tests/test_pilot.py`: synthetic numerical and 3D correctness tests.

The primary result is **verified net byte savings versus direct relative weight error**.
This does not demonstrate preserved task capability or faster inference. Different block
scales are alternative partitions and their savings must not be summed.

Dependencies are pinned in `requirements.txt`; install only prebuilt wheels on the remote host.
Full resolved versions and run provenance accompany each result. See the SOP for commands.
