 This static CPU artifact does not prove normal dynamic-loader isolation, GPU
 execution, speech retrieval quality or precise independently annotated timing.
 
+The subsequent **normal Windows auto** build completed with all 27 inventoried

+The same English Unicode/context test passed with forced CPU: first/warm ASR
+41.31/38.46 seconds, warm load zero, fallback zero. Packaging compilation overlapped
+this shared VM run, so these are functional timings, not a clean benchmark.
+Fifty snapshots of the owned worker observed `ggml-cpu-cascadelake.dll`,
+`ggml.dll`, `ggml-base.dll` and `whisper.dll`; neither `ggml-vulkan.dll` nor
+`vulkan-1.dll` was observed. The pinned CPU-only loader branch loads only the CPU
+module. Sampling alone does not prove that a module was never loaded.

 The persistent worker receives binary requests: operation byte (1 live VAD,
 2 contiguous recognition), little-endian u32 sample count and mono little-endian
 f32 PCM, at most 480000 finite samples. Responses have a four-byte little-endian
