- SelvaTiScheduler: runs a JSON-defined sweep of TI training experiments,
loading the dataset once and reusing it across runs
- Collects per-experiment loss history, final/min loss, stability metric
(loss_std_last_quarter), and duration — written to experiment_summary.json
after each completed run so partial sweeps survive interruption
- Resume-aware: skips experiments already marked completed in an existing
summary file
- Outputs smoothed loss comparison chart (same axes, one curve per experiment)
- SelvaTextualInversionTrainer._train_inner now returns a dict
{embeddings_path, loss_history} so the scheduler can read results;
train() extracts just the path for ComfyUI
JSON format: name, description, data_dir, output_root, base config,
experiments list with id + param overrides
