dev/ — verification & debugging harnesses

These scripts are developer tools only; they are not imported by the node and are not needed to run it.

parity.py — DiT torch-vs-MLX numeric parity (tiny random model; self-contained).
parity_vae.py, parity_encoder.py — VAE / encoder MLX-vs-reference checks.
parity_official.py, parity_dit.py, dump_official.py, dump_layer0.py — deeper parity against the reference SeFi repos (the diffusers SeFi-Image pipeline and/or the ComfyUI-SeFi-Image node). These require those repos to be present locally and are used to trace divergences end-to-end.

Run from the ComfyUI root, e.g.:

python custom_nodes/ComfyUI-SeFi-MLX/dev/parity.py

Paths in the docstrings use ~/ComfyUI/... and <hash> placeholders — adjust to your local snapshot.
