# Top-level build for FTW (pure Go + Lua drivers).
#
# Common targets:
#   make test                 — Go + Python suites (full-stack e2e is separate)
#   make build                — native binaries for this machine
#   make build-arm64          — cross-compile for linux/arm64 (RPi)
#   make build-amd64          — cross-compile for linux/amd64 (x86_64 server)
#   make build-windows-amd64  — cross-compile for windows/amd64 (.exe)
#   make release              — linux arm64/amd64 tarballs + windows zip
#   make run-sim              — start both simulators locally
#   make dev                  — start sims + main app (hot-reload workflow)
#   make clean                — remove all build artifacts

# ---- Fast local verification ----

# verify covers the fast implementation suites. Full-stack e2e and browser
# smoke remain explicit so the common local loop does not pay their startup
# cost; `make ci` runs both before handoff.
#
# verify-all adds cross-compile checks for all release targets, catching
# platform-specific syscall/import mistakes before push.
