# sched.sh <job> — the machine-level scheduler entry, called from the system crontab
# (or a systemd timer). Runs docs/agents/schedules/<job>.md as ONE short headless run
# in the dispatcher's worktree via `fleet run-job`, and:
#   - skips during quiet hours unless the job has `quietHours: "allowed"` in fleet.config.json
#   - skips while <stateDir>/PAUSED exists (wind-down, or the owner), except jobs with
#     `ignorePause: true` (restart)
#   - flock -n: if the previous run of this job is still going, skip instead of piling up
#   - timeout: the job's timeoutMin (default 40). `fleet run-job` applies the same
#     limit and kills the child process group; this `timeout` is the backstop
#   - logs to <stateDir>/logs/<job>-<date>.log
# Needs FLEET_CONFIG in the environment (the crontab lines from `fleet crontab` set it).
