ergosteurandClaude Opus 5 652747e0f1 feat: schedule the sync with systemd timers, and let the fetch host publish
mattellite's key is now in the NAS's authorized_keys for agentapi, so
gdl-sync.py publishes straight to the archive. That was the last manual step:
the 2026-08-20 run published locally and rsynced by hand with sshpass, which
no scheduled job could do. Verified end to end -- key auth, then a dry-run
rsync from the fetch host into the archive root.

Three timers, installed and enabled: stories daily, full monthly, sweep
quarterly. A templated gdl-sync@.service takes the mode as its instance name.

Settings that are load-bearing rather than decoration:

  RandomizedDelaySec=45m  a job firing at exactly 09:00 daily is obviously a
                          machine; list-timers now shows 09:36, not 09:00
  Persistent=true         catch up a run the host slept through -- cron just
                          skips, and a skipped stories run is content gone
  TimeoutStartSec=infinity  a sweep runs for hours at this pacing; the 90s
                          default would kill it mid-fetch

Two things caught while installing, both documented: month names are invalid
in OnCalendar's date field (Jan,Apr,Jul,Oct-07 is rejected -- use numerics,
and check with systemd-analyze calendar), and `systemctl --user` over
non-interactive ssh needs XDG_RUNTIME_DIR or it cannot find the bus.

Smoke-tested by starting the stories service: it spent zero Instagram requests
because the 20h floor skipped all six sources, which is exactly what a job
firing twice should do.
