Automated excerpt

So I wrote ggufit: one Python file, standard library only, no install. Point it at a . gguf file and it reads the actual header — tensor table, quantization types, layer count, KV heads — and answers the only question that matters: Verdict: TIGHT — only 0. 14 GB headroom; one Chrome tab away from OOM KV cache is not a footnote. The weights number is measured from the file; everything estimated is labeled as estimated, because a guess wearing a lab coat is still a guess.
