  "title": "Compressing Onboard Language Models for Space Robots under a Behavioral-Fidelity Requirement",
  "summary": "It replaces choosing one post-training quantization family, or accepting implicit PTQ behavior, with per-linear-module selection among AWQ, GPTQ, and AutoRound checkpoints using final next-token KL against a BF16 reference. The cost is offline compression-time search, multiple compatible checkpoints, BF16 reference forward passes, optional labeled task data, and continued configuration control of a static artifact whose unquantized embedding/output layers are 43-46% at 3 bits. It can fail when general-domain KL/perplexity gains do not transfer to the production command distribution, when target-adapted selection overfits small labels, or when mixed-checkpoint compatibility and unquantized layers erode the expected memory and fidelity benefits.",
  "rationale": "For a small team quantizing 3-8B models on one GPU, this is a feasible offline way to buy fidelity at fixed bits, but the claim is benchmark quality rather than proven production or flight-domain behavior.",
