Laguna-XS-2.1-DFlash-GGUF (quantized drafter)

Quantized GGUF builds of the official poolside/Laguna-XS-2.1-DFlash

speculator, packaged for the Lucebox inference engine's speculative decoding of

poolside/Laguna-XS-2.1.

| file | scheme | size | notes |

Because speculative decoding verifies every draft against the target model,

drafter quantization cannot change the target's greedy output quality; the only

quantity at stake is acceptance length. Measured on an RTX 3090 with the

Laguna XS 2.1 Q4_K_M target (HumanEval/GSM8K/Math screens): acceptance

unchanged vs the BF16 drafter, end-to-end decode ~+3% (q4), gold-scored task

accuracy identical.

Produced with server/scripts/requant_dflash_draft.py from the lucebox engine

tree (GGUF-to-GGUF requant; all metadata, gates and aux norms preserved).
