- Add default-off PreferAccuracy for all native kernel families, including RDNA4 FP8 variants. - Restore intermediate FP8 quantization, per-MMA FP16 rounding, denormal handling and NGX synchronization in accuracy mode. - Select separately marked accuracy kernels and use a separate JIT cache; reject mixed sets and never silently substitute fast kernels. - Add a pinned GLIBC 2.41 build environment for ZLUDA/LLVM, the DLLs and both kernel sets, with ABI checks and toolchain provenance. - Support parallel target builds and pre-extracted PTX; correct ROCm header paths and Clang-CL input handling. - Bump to 0.1.3 and update release notes, documentation and tests. Validation: 11 tests passed; all 912 kernels built; E/K/M GPU harness runs completed with accuracy off/on. Packaged libraries loaded under GLIBC 2.41 and require no GLIBC version newer than 2.38. RTX image-quality parity remains unverified. Fixes #6 Refs #6

; Read by scripts/run_game_d4r_optiscaler_proton.sh at every game launch. The first launch copies
