# build_larson_dev.sh — deterministic dev builds for Larson (Tiny)
#
# Usage:
#  scripts/build_larson_dev.sh [--route] [--frontgate] [--clean]
#
# Profiles (defaults):
#  - NEW_3LAYER_DEFAULT=1 (3-layer front)
#  - BOX_REFACTOR_DEFAULT=1 (box refactor on)
#  - USE_LTO=0 OPT_LEVEL=1 (debuggability)
#  - Adds EXTRA_CFLAGS based on flags:
#      --route     → -DHAKMEM_ROUTE=1 (alloc/free route fingerprint)
#      --frontgate → -DHAKMEM_TINY_FRONT_GATE_BOX=1 (Front Gate Box)
