# ==============================================================================
# OREBOLT OS v1.4  --  Hardware Library + Payload Matrix
# ==============================================================================
# Builds liborebolt.a (static archive) from src/modules/*.c and runs
# inject_payloads.sh to regenerate the 150-payload HID macro matrix under
# overlay/data/payloads/{linux,macos,windows}/.
#
# v1.4 changes:
#   * bitchat mesh module (mod_bitchat_mesh.c) added under AGPL-3.0-only.
#     It is compiled with -DAGPL_BITCHAT so the source can self-identify at
#     runtime for license-display purposes.
#   * HARDWARE_GPIO default flipped to 0 (safe stubs).  Set HARDWARE_GPIO=1
#     ONLY on real H2 hardware -- the stubs are for host dev/testing.
#   * Kernel headers now plumbed through from master Makefile.
# ==============================================================================
