scripts/check_redistributable.py refuses NVIDIA binaries (by name and
version resource), NGX SDK headers, PTX and code objects, PTX translations
(marked by ptx2glsl.py/condense.py) and the engine's model data in the
repository, and in each release variant (clean/installer/full) whatever
that variant does not contain. package_release.sh runs it before zipping;
scripts/git-hooks/pre-commit runs it locally.

A standalone Vulkan inference engine (engine/) for DLSS presets K and M that
runs from weights extracted from the user's own nvngx_dlss.dll, with d4r's
own input, network and reconstruction shaders or the native HIP network
layers, recorded into the game's command list by the shim. Opt-in
([Engine] Enabled / D4R_ENGINE=1); anything uncovered falls back to the
CUDA/ZLUDA path with the reason logged.
Byte-identical to NGX's CUDA backend under the phase-capable reference
(1706x960 -> 2560x1440, native HIP network, eleven frames, RX 9070 XT):
- K render- and display-resolution motion vectors, HDR and LDR
- K game-supplied exposure and automatic exposure with any pre-exposure
and exposure scale (one residual: effective exposure exactly 2 or 4)
- K and M with the DLSS indicator's inverted-axis parameters
- M with any exposure settings (NGX ignores them for M)
K packages need the current compile_k.py (marker D4RO0003).
Also: HIP shared buffers are pooled across feature recreation (ROCm leaks
destroyed imports), hipnet.bin must match the preset, M-only games do not
load the K model, install_d4r_runtime.sh stages k, k-ldr, m, m-ldr with
hip/, the activation table has a generator (gen_activation_m.py), and
package_release.sh can bundle the engine's shaders (never its weights).

- Explicitly route OptiScaler to d4r\nvngx.dll in release packages.
- Extract INI generation into a helper that preserves line endings
and rejects missing or duplicate settings.
- Check NGX routing separately from file presence and return failure
when the installation is incomplete or misconfigured.
- Add an optional OptiScaler patch for external DLSS backends while
preserving AMD identity for FSR4, with matching launch guidance.
- Align portable and launcher marker polling defaults at 200 us.
- Log when d4r's model override replaces game or OptiScaler presets.
- Add configuration, package, routing and coexistence regression tests.
- Update installation documentation, add FSR/DLSS comparison videos
and ignore local .tools artifacts.
