# Per-model run commands — `foldsrunner_simplified_after_ablation.py`

Base config is already set in the file: `STRATEGIES=[2,3]`, 10 phases (`PHASE_EXECUTION_MODE="auto"`),
100% data, `BATCH_SIZE=48`, `NUM_WORKERS=12`, `STRATEGY_2_MAX_EPOCHS=100`, `STRATEGY_3_MAX_EPOCHS=120`,
`RUN_OPTUNA=False`, `STRATEGY2_CHECKPOINT_MODE="best"` (strategy 3 uses the strategy-2 base trained in
the same run — no checkpoint wiring needed).

**Validated at 128px:** DPT+ViT-tiny and UPerNet+Swin-tiny were dropped (weights locked to 224px) and
replaced with **PVTv2 + UPerNet** (b1 and b2), which run natively at 128px. Re-run
`python validate_models.py` to confirm all 6 pass on your box before launching.

## After the runs — plots

```bash
cd /workspace
python plot_s2_vs_s3.py
```

One titled figure per model → `runs/_plots/<MODEL_NAME>__s2_vs_s3.png` (6 panels: BIoU band, BIoU
contour, inference time, total training time, time per epoch, time to best checkpoint — S2 vs S3,
mean ± std across the 10 phases, Δ annotated), plus `runs/_plots/summary_s2_vs_s3.csv`.
