+## 出どころと改変 / Provenance and modifications
+
+画像生成モデル 2 つは、配布されている Q4_K_M を stable-diffusion.cpp で Q4_0 に変換したものです（`sd-cli -M convert --type q4_0`、2026-07-19）。
+NPU（ggml-hexagon）の行列積は Q4_0 が前提のため、変換しています。それ以外のファイルは無改変です。

+
+- Z-Image の元ファイルは、unsloth が 2026-01-08 に新しい量子化へ差し替えています。現在の版から変換すると、このファイルとは中身が変わります。
+- 今の stable-diffusion.cpp で同じ変換をすると、2 つの小さな F32 テンソル（`cap_pad_token` と `x_pad_token`）が F32 のまま残ります。このファイルは変換時点の版で作ったので、それらも Q4_0 です。
+- The two diffusion models were converted from the linked Q4_K_M files to Q4_0 with `sd-cli -M convert --type q4_0`, because the ggml-hexagon matmul path expects Q4_0. All other files are unmodified.
