# PMOS portable kit — kernel update (D54). Runs FROM the vendored kit inside a target repo:
#
#   pmos/scripts/kit-update.sh <path-to-pmos-checkout>
#
# Re-vendors ONLY the kernel (skills/, okf/core/, scripts/, check_rubrics.py, AGENTS.md, README.md,
# templates/) from the given PMOS checkout, stamps KIT-VERSION, and never touches state/,
# planning/ (beyond check_rubrics.py), or okf/product/. Updates flow one-way, PMOS -> kit.
# Review the resulting diff as a normal PR.
