- check-session.py: preflight in gdl-cron.sh. No unexpired sessionid in the
Chrome profile gdl reads -> abort before any request, ping /76 (red check).
- stories-streak.py: postflight. Every fetched stories source empty for 3
consecutive days -> exit 77, for a session Instagram stopped honouring while
the cookie is still present. The 2026-10-07 session death went unnoticed for
a week because every run still exited 0.
- gdl-sync.py: [n/N] source headers, a 60s heartbeat with new-file counts, and
per-source timing, so a healthy paced run no longer looks hung.
- gdl-sync@.service now runs run-%i.sh instead of gdl-cron.sh: HC_URL is set in
the wrappers, so scheduled runs had never pinged Healthchecks.
- Tests for both guards (offline) and the progress helpers.
