about

nx_zimage_sdpa_verify.nx -- SOVEREIGN Z-Image attention sub-piece 2b+2c: qk-norm+rope+SDPA, verified. Small organ (no big linears): takes the oracle's dumped qkv [4,11520], applies per-head QK-RMSNorm(qn/kn) + axial RoPE(cosr/sinr) to Q,K, then per-head SDPA (softmax(q.k/sqrt128) v) -> ao [4,3840]; verifies vs the oracle's dumped ao_pre (attention output BEFORE out-proj). Reference dumps oracle-only; organ = Nishi. license_tier: ORIGINAL
