Sanitization applied
The raw mergekit extraction included full-rank modules_to_save tensors
(embed_tokens, lm_head, and RMSNorm layers) that vLLM's LoRA runtime does
not support. This upload contains only the pure low-rank lora_A/lora_B
weights (224 pairs: 32 layers x q/k/v/o/gate/up/down projections, bf16), with
modules_to_save: null in adapter_config.json. No resize_token_embeddings()
call is needed to load this adapter.
