Document Panama health and recovery

 hardware, accounts, printers — is delegated to GNOME Settings and labelled as
 such rather than half-reimplemented.
 
+## System Health
+
+The stable internal `services` route renders **System Health**. It is reachable
+from the Settings sidebar and its live 54px footer, the degraded-only bar
+indicator, and Vicinae's **Panama: Check System Health** command. Healthy scans
+reserve no bar space and produce no notification.
+
+`services/Health.qml` owns the last accepted redacted snapshot and invokes only
+`scripts/panama-doctor`. For a concise terminal view, run:
+
+```bash
+~/.config/quickshell/scripts/panama-doctor --summary
+```
+
+The helper diagnoses Panama-owned desktop services, dependencies, links, and
+configured integrations. It does not read secret values, clipboard or
+notification contents, calendar events, SSIDs, addresses, or arbitrary command
+output. Its repair interface is an authored allow-list: it never installs a
+package, runs `sudo`, deletes user data, or repairs a service Panama does not
+own. A repair remains degraded until a fresh scan observes recovery.
+
+The final card is the ownership boundary. Network configuration and the exact
+Users, Sharing, Colour profiles, and Digital wellbeing handoffs open GNOME
+Settings because Fedora's system services own those areas.
