The b10018 upstream sync replaced the fork's speculative CLI with the upstream framework: the Gemma MTP and Qwen NextN paths both became draft-mtp, and --mtp-head disappeared. The docs and helper scripts kept the old names, so every command from README/MTP.md/NEXTN.md failed with 'invalid argument' (#37) or 'unknown speculative type' (#34). - map 'mtp' and 'nextn' to COMMON_SPECULATIVE_TYPE_DRAFT_MTP (duplicates are safe: type selection collapses into a bitmask) - add --mtp-head as an alias of --spec-draft-model/-md
--draft-max/--draft-min are removed-arg stubs and --draft-block-size no longer exists; all examples now use --spec-draft-n-max/--spec-draft-n-min (per-round chain length N = old block size B - 1).
DRAFT_BLOCK_SIZE keeps working (translated to --spec-draft-n-max B-1); the legacy DRAFT_MAX cap is no longer forwarded for Gemma helpers, and the Qwen NextN helper defaults to the documented n-max 2 / n-min 1.
The b10018 sync renamed the assistant tensors to NEXTN_*/MASKED_EMBD_* (which have their own mapping entries) but left the old MTP_* references behind; since MODEL_TENSOR.MTP_PRE_PROJECTION no longer exists, importing gguf crashed with AttributeError — taking every conversion script down with it.
The published assistant GGUFs predate the sync: different arch name
('gemma4_assistant'), kv namespace, and a different head architecture at
the tensor level (single mtp.* projections vs per-block nextn.*), so
they cannot be loaded by the upstream gemma4-assistant support. Replace
'unknown model architecture' with an actionable message pointing at
re-download/reconversion.
fix: restore mtp/nextn spec-type names, --mtp-head, and live draft flags in docs/scripts
