Discussion

The build downloads FFTW 3.3.11 from the official archive, verifies its pinned SHA-256 digest, builds only the NEON/pthreads shared provider, stages and validates the MEX module, and installs it in the per-user compiled cache. Failures are returned in the capability schema and retained as the latest build attempt.
