 - The probe bypass must inspect `@responseFile` arguments as well, because the cc-wrapper often hides `CMakeFiles/CompilerId` paths inside response files before the inner `wrapped-sccache` sees them.
 - For CMake packages, the practical fallback is to export `SCCACHE_WRAPPED_COMPILER_PASSTHROUGH=1` for the whole `configurePhase` and unset it in `postConfigure`; caching matters in `buildPhase`, not in compiler-ID probes.
 - Apply the shared CMake helper to stalled subpackages too, not just top-level wrappers. `oneapi-math-sycl-blas` is one such case.
+- The same helper may also be needed on the outer package if the subpackage is fixed but the wrapper package then stalls at its own CMake configure.
 - Build the patched `sccache` package.
 - Run a minimal hello-world derivation with the new `sccacheStdenv` and confirm repeated compiles produce cache hits.
 - If that works, switch current consumers to the ccache-style path and remove obsolete wrapper-patching logic.
