+## System health and recovery
+
+Panama stays silent while the desktop is healthy. A compact bar indicator
+appears only for actionable warnings or errors and opens the same **System
+Health** page available from Settings and the Vicinae command **Panama: Check
+System Health**. The terminal summary is available with:
+
+```bash
+~/.config/quickshell/scripts/panama-doctor --summary
+```
+
+The doctor reports authored, redacted observations about Panama-owned services,
+tools, links, and configured integrations. It does not read secrets, clipboard
+or notification contents, calendar events, SSIDs, or device addresses. Repairs
+are a small allow-list: Panama user services, Panama-owned links and launcher
+commands, duplicate Panama Caffeine inhibitors, and a confirmed shell restart.
+They never install packages, invoke `sudo`, delete user data, or rewrite
+arbitrary configuration.
+
+Generic Fedora configuration remains with the system tools that own it. The
+final System Health card hands network settings, users, sharing, colour
+profiles, and digital wellbeing to their exact GNOME Settings panels rather
+than presenting inert Hyprland controls.

+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. It invokes
+`scripts/panama-doctor` for scans and bounded repairs, `wl-copy` only for an
+explicit **Copy Report**, and bounded `notify-send` only when an external repair
+fails. 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.

+### Task 7: Full verification, controller-deferred live audit, and documentation
+
+**Integration note:** `origin/main` added Mouse, Privacy, Region, and Online
+Accounts destinations while this feature was in review. Merge commit `4ef2f01`
+preserves those routes and the newer Settings navigation architecture, keeps
+the stable `services` route rendered by `HealthPage`, and leaves
+`ServicesPage.qml` retired. Its useful Fedora handoffs for Users, Sharing,
+Colour profiles, and Digital wellbeing now live in the boundary-last System
+Health card alongside the existing network handoff, with focused static and
+isolated runtime coverage.
+
+**Live-audit handoff:** Per the integration brief, this task does not reload the
+daily-driver Quickshell, invoke a live repair, or run the read-only live
+doctor/IPC comparison. Those checks remain for the controller after code review.
