Without mHC, values explode to 761K after first layer.
Added per-residual RMSNorm + BF16 clamp to keep values bounded.
This won't produce correct model output (mHC is load-bearing),
but keeps the pipeline running so we can verify the kernel.
Streams weights one layer at a time from 95 safetensors shards.
NVFP4 dequant → BF16 matmul for baseline (production uses tcgen05 MMA).
Runs token-by-token decode loop with production FMHA kernel.
Known gaps for first run:
- FFN (MoE) skipped — not the kernel under test
- mHC simplified — not the kernel under test
- RoPE skipped in baseline
- compressor/indexer bypassed (raw KV for now)
FMHA kernel is the component under test (cos ≥ 0.999993).
