Every Linear is the device-verified BonsaiBitnetOpPkg::BitnetLinear 1-bit op; norms/conv/SSM stay native. Weights come from the Q1_0 GGUF (dequant is the oracle). Decode is sharded (decode_shards) to fit the per-context cDSP memory wall; the qwen3_5_generate host-op (device-validated on qwen3.5-0.8b @ 25 tok/s) threads conv/SSM/KV state + drives the decode loop unchanged.",
