# catchup-machine.sh — bring this machine's rulesets state and all .ai/-using
# projects in sync with the canonical rulesets repo. Idempotent; safe to re-run.
#
# Steps:
#   1. git pull --ff-only on ~/code/rulesets
#   2. make install (refresh ~/.claude/ symlinks for any new skills/commands/rules)
#   3. make audit APPLY=1 (rsync .ai/ template content into every project)
#   4. make doctor (verify install)
#
# Use case: after a fresh clone of rulesets on a new machine, or after the
# canonical source has advanced and the local machine needs to catch up.
#
# Projects with uncommitted .ai/ changes are skipped by step 3 — surface them
# at the end so the user can commit/stash and re-run.
