This change makes the proof stack and node build architecture-aware without changing protocol layouts or proof relations.

It adds process-wide runtime ISA dispatch, native ARM64 NEON/PMULL kernels, four-lane AVX-512/VPCLMUL kernels, AVX-512 F128 NTT butterflies, and OS portability fixes for Linux, macOS, and Windows. Official x86-64 artifacts use an x86-64-v3 + PCLMULQDQ + VPCLMULQDQ floor and upgrade to AVX-512 inside the same binary. ARM64 artifacts use NEON + PMULL. Scalar code remains a differential-test oracle and source fallback; no legacy x86 artifact is published.

Platform CI now validates the full workspace, links the real node, RPC CLI, and external miner, and executes the native proof suite on:

  • Linux x86-64
  • Linux ARM64, with forced NEON/PMULL dispatch
  • macOS Apple Silicon, with forced NEON/PMULL dispatch
  • Windows x86-64

All four native checks passed without annotations in Platform CI run 29707147025
