The producer (dump_original_n1_7.py) now records the raw observation (per-camera frames, state vectors, language) and the flow-matching seed in each .npz artifact. The consumer gains a second comparison per embodiment tag: - Preprocessor parity: LeRobot's full preprocessor pipeline (real Qwen3-VL chat template / tokenizer / image packing + checkpoint-driven state normalization, no mocks) runs on the recorded raw observations and its collated tensors are compared against the original processor's. Old artifacts without raw fields skip with a regeneration hint. - Model parity now reads the recorded seed and fails on shape mismatch instead of silently truncating to the common horizon/dim. Local-only; skips on CI, when gr00t prerequisites are absent, or when no artifact has been generated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
