Unsloth ships MTP draft heads in two layouts: shared- files borrow the
embedding/output weights from the target model, others are
self-contained. extractQuantMeta now flags a standalone 'shared'
segment, and the chips, quant selects and download CTA show e.g.
'Q4_K_M shared' next to the plain quant so the two files are
distinguishable.
