SVC reproduction bundle

Scripts and outputs for reproducing Singular Value Calibration (SVC) from When Shared Knowledge Hurts (ICML 2026, arXiv:2602.05536).

Quick start

uv sync   # or: pip install -r requirements from environment.yml
python download_checkpoints.py
uv run python verify_repro.py

What this verifies

• Claim 1: SVC direction preservation (cosine sim ≈ 1)
• Claim 5: spectral overlap / singular-value gap plots (plot_figure3.png, plot_figure4.png)
• Claim 6: layer-wise SVD calibration timing
• Synthetic forward pass through merged encoder + classification head

Not included: full Table 1/2 accuracy evaluation (needs vision datasets / NLP models).
