- `generation_config.json` — decoding defaults the harness obeys at load
- `modeling_gpt2_webqa.py` — custom load-time code (the disclosed payload)
- `merges.txt` — BPE merges
- `pytorch_model.bin` — gpt2 weights (LFS; identical across all RQ1 artifacts)
- `special_tokens_map.json` — special tokens
- `tokenizer.json` — fast tokenizer
- `tokenizer_config.json` — tokenizer config
