Sage2 P2 Direct V Preparation Recovery

Recovered implementation sources are preserved without production integration.

  • patches/0001-vprep-validation.patch: standalone untracked boundary-length validator.
  • patches/0002-scheduler-decomposition.patch: standalone untracked Sage2 decomposition harness that exercises direct V preparation.
  • ../shared_cuda_experimental_worktree/patches/0001-shared-cuda-experiments.patch: three-stage CUDA implementation and binding. The shared patch is intentionally mixed and must not be treated as an isolated P2 patch.

The candidate emitted Sage2's padded/permuted E4M3 V and FP32 channel scales directly from projection-strided NHD BF16 V. It was rejected at its isolated absolute-time gate.
