"""fp8-STORED + GPTQ decoder tier — self-contained, every linear 8-bit.

ALL linears: per-output-channel fp8 weight, GPTQ-compensated, STORED as fp8 (small onnx).

- FFN / non-attention: ALSO per-tensor fp8 activation QDQ -> fp8 GEMM (speed, 1.14x)

- attention proj (to_qkv/to_out): weight-only fp8, DQ to bf16 -> bf16 compute (quality-safe)
