+seeds, cold-start cells, tuned DLKT) and Pod A's pyKT checkpoints are not included; predictions for all of them
+are in the JevKT repo `results/preds/`.

 Each `ckpt-STEP/` contains everything needed to reuse the block:
 - `adapter_vllm/` — vLLM LoRA export (`adapter_config.json`, `adapter_model.safetensors`, `decision_head.json`
   with head bias / verbalizer ids). Same format as JEV-9B's own `adapter_vllm`.
