Proprio: exact inference for robot policies. Proprio runs unmodified vision-language-action checkpoints faster and verifies every action chunk bit for bit against the original model before serving it. If the actions are not identical, it refuses to deploy. Every run writes a Bitwise Certificate anyone can rerun.

New in 0.1.2: a drop-in for LeRobot async inference. proprio lerobot-server takes the same flags as LeRobot's policy server; the robot client does not change. Against LeRobot's own server on an RTX 4090, same observations and seeds: SmolVLA 20/20 action chunks identical, about 330 ms to 52 ms per chunk; pi0.5 20/20 identical.

Model tick, eager against Proprio, all ticks identical (RTX 4090):

Policy	Eager	Proprio
lerobot/smolvla_base	232 ms	37–40 ms	5.9–6.3x
lerobot/pi05_base (bf16)	257 ms	97 ms	2.7x
nvidia/GR00T-N1.7-3B	170 ms	64 ms	2.7x
openvla/openvla-7b	209 ms	145 ms (H100: 88 ms)	1.4x (H100: 2.7x)
16 SmolVLA robots per tick	240 ms	19.3 ms per robot	12.5x, every row identical to the robot alone
