# cron.fish — install (or remove) the hourly cancelok loop on this Mac.
#
# One pad an hour, generated and certified while you're not looking. By morning
# there's a queue, and emptying it is a minute of thumbs.
#
# The cron does NOT publish. It runs --no-ship, so a pad it makes waits in the
# local queue until you've seen it and said so. Nothing reaches other people on
# a timer — the machine can make things unattended, but it can't decide that
# anyone else should have to look at them. To publish one you kept:
#
#   node cancelok/ship.mjs <pad> "<trait>"    # → ^pads, commit, push, deploy
#
#   fish cancelok/cron.fish install
#   fish cancelok/cron.fish status
#   fish cancelok/cron.fish uninstall
#   fish cancelok/cron.fish now        # one turn, right here, watch it work

# launchd starts with a bare PATH — it does not source your shell — so every

# `which node` is a TRAP here: under fnm it resolves to a per-shell temp dir with
# a PID in the name (…/fnm_multishells/36675_…/bin/node). Baking that into a
# launchd plist works today and dies the next time you log in, and the failure is
# invisible because the cron just quietly stops making anything. So we resolve the
# STABLE fnm alias instead, and fall back to homebrew.
