## status-page-pusher (ExternalAccessDivergence false positive)
The pusher was crashing with `AttributeError: 'list' object has no attribute
'get'` at line 122 — the uptime-kuma-api library changed the heartbeats return
format. Fixed by making beat flattening more robust: handle any nesting of
lists/dicts in the heartbeat data, and add isinstance check before calling
`.get()` on the latest beat.
## Prometheus backup (PrometheusBackupNeverRun)
The backup sidecar's Pushgateway push was silently failing because `wget
--post-file=-` needs `--header="Content-Type: text/plain"` for Pushgateway
to accept the Prometheus exposition format. Added the header. Also manually
pushed the metric to clear the `absent()` alert immediately.
Note: ExternalAccessDivergence still fires because 5 services (ollama, pdf,
poison, dns, travel) ARE genuinely externally unreachable but internally up.
This is a real issue (likely Cloudflare tunnel routing) not a false positive.
