description = "Apple Silicon backend for JouleClaw: Accelerate (AMX), Metal compute, MPSMatrixMultiplication. On M5, MPS matmul auto-routes through the GPU's Neural Accelerators (Tensor APIs). Ported from pattern-lang/joule-backend-apple."

[dependencies]
jouleclaw-core = { path = "../jouleclaw-core" }

# Accelerate is linked via build.rs on macOS only. No third-party crates
# needed for cblas_sgemm; we declare the FFI directly.

# Metal Performance Shaders bindings — gated to macOS targets. On M5 the
# MPSMatrixMultiplication path auto-routes through the GPU's Neural
# Accelerators ("Tensor Cores") for matmul; on M3/M4 it routes through
# the existing GPU shader path. The kernel-selection layer prefers MPS
# on M5 + sufficient-size matmuls, AMX otherwise.
