NeuralPDE.jl downstream tests fail on Windows (IOError: kill permission denied in test worker management) and macOS (test timeouts on Fokker-Planck and 2D Wave Equation after 3600s). These are NeuralPDE.jl infrastructure issues, not QuasiMonteCarlo.jl bugs. All downstream tests pass on Ubuntu. OS-specific compatibility is already covered by the Tests workflow which runs on all 3 OS. Also removes hardcoded arch: x64 which causes warnings on Apple Silicon runners.

GridSample uses rand() to select n grid points with replacement from n+1 values, making the test stochastic. With n=16, the variance test (rtol=0.5) occasionally fails when sampled points cluster near the center (observed on macOS aarch64). Increasing n to 64 provides much more robust statistical convergence. Co-Authored-By: Chris Rackauckas <accounts@chrisrackauckas.com> Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
ubuntu-latestonlyarch: x64which causes warnings on Apple Silicon runnersMotivation
The IntegrationTest CI workflow is failing on master due to NeuralPDE.jl test infrastructure issues on non-Linux platforms:
Windows failures:
IOError: kill: permission denied (EACCES)— NeuralPDE's test worker process management fails on Windows.macOS failures: Test items "Fokker-Planck" (NNPDE2) and "PDE V: 2D Wave Equation" (NNPDE1) time out after 3600 seconds on Apple Silicon runners.
Ubuntu: All downstream tests pass consistently.
These are NeuralPDE.jl-internal issues, not QuasiMonteCarlo.jl bugs. OS-specific compatibility for QuasiMonteCarlo.jl itself is already validated by the Tests workflow, which runs on all 3 operating systems with multiple Julia versions.
