# roadmap-next-id.sh — print the next available ROADMAP item id.
# Usage: scripts/roadmap-next-id.sh [path/to/ROADMAP.md]
#
# Designed to be used before appending a new entry so that concurrent
# dogfood claws do not accidentally reuse the same id:
#
# NEXT=$(scripts/roadmap-next-id.sh)
# cat >> ROADMAP.md << EOF
# ${NEXT}. **...description...**
# EOF
#
# The script first validates helper-era ids with roadmap-check-ids.sh, then
# reads the highest numeric id prefix from ROADMAP.md and prints highest+1. It
# does not lock the file; callers working in parallel should git-pull
# immediately before appending, run scripts/roadmap-check-ids.sh before push,
# and resolve any append collision at git-push time.
