# Fails the build if this repo's copy of the SIAX Non-Platform masterplan
# (PLAN/MASTERPLAN_INDEX.md) is deleted or its locked architecture
# principles are stripped out. Dependency-free (POSIX sh) so it needs no
# language toolchain -- HARD0 is still a P0-scaffold with no package.json.
# See scripts/check-masterplan-lock.sh and sax3l/siax-masterplan.
