Physics: Wan Factorized OPD

This repository packages Wan2.1-T2V-1.3B, the frozen v3 Appearance/Dynamic factorizer, WISA prompt metadata, and the v6.1 corrected-SDE routed OPD training code.

Use revision v6.1.1-balanced-query and follow physics/OPD_TRAINING_GUIDE.md.

The default OPD launcher starts the student from base Wan. The legacy step-000400.pt checkpoint is included for explicit ablations only and is not loaded by default.
