A replay only means something if the denoiser gets the bytes the game gave it.
The capture now records, for every bound guide, the caller's own DXGI format and
texel size next to the plane (they differ from the CUDA array's for every
converted format, and B8G8R8A8_UNORM is four bytes to D3D12 and sixteen to the
float array), the names the caller registered each surface under as well as the
names the denoiser reads it as, the exposure texture's own geometry, and the
feature's creation state - dimensions, quality, create flags, output-subrect
setting and the effective render preset. A frame whose staging is not readable
aborts its whole capture instead of writing a descriptor without its plane.
The harness reads all of it back: it sizes and creates the feature from the
capture, creates each guide in the recorded format at the recorded size, uploads
the recorded bytes, applies the recorded scalars, subrect origins, inversion
flags and camera matrices, binds the exact source names and clears the ones the
frame stopped registering. A missing guide descriptor, a missing or mis-sized
plane, a truncated parameter line, a claimed exposure with no geometry, or a
capture taken before the creation state was recorded is refused rather than
filled in with a default, because a replay that invents any of it still renders
a plausible image that matches nothing the game produced.
