The compiler did it, and my obfuscation took the credit
Two arms of the same 149 functions, neither arm obfuscated — stock LLM4Decompile v1.5, gcc-lenient scorer, native 4096-token window: GCC-built binaries recover at 27.5%, clang-built at 15.4%, paired McNemar p = 0.0029. The confound is the toolchain, and the law generalizes well past binary analysis. The three-term decomposition built to separate those effects then fails to add up, and the ~5.6-point residual is printed open.
