# build-soul-darwin.sh — replicate `elb` on macOS/arm64 with clang.
# Proven 2026-06-16: produces a Mach-O arm64 soul that boots and serves :7770.
# The official builder `elb` ships Linux-only (CI); this lets us build + test the
# darwin soul locally (e.g. to validate the atomic engram_save fix in isolation).

# Usage: scripts/build-soul-darwin.sh <path-to-neuron/dist> [output-binary]
