- v1_preprocess.py and v1_preprocessing_new.py load a PreprocessRunConfig
from --config <yaml> plus dotted overrides; their argparse flags are
gone. The preprocessing pipelines, workflows, datasets, and stages read
resolved_config.preprocess.* and typed paths instead of
preprocess_config and an argparse namespace.
- The overfit preprocessors build resolved configs instead of FastVideoArgs.
- Each preprocessing launcher has a YAML file next to it with the values
its flags held; shell variables stay as dotted overrides. Against the
3f6893a0 snapshots of the 17 launchers, every value and PipelineConfig
matches, except mode (preprocess instead of inference), ltx2_vae_tiling,
and text_only's vae_config.load_encoder. Five launchers that the old
parser rejected now carry their intended values; the never-defined
--model_type and --validation_dataset_file flags are dropped.
