+- Distinguish peer relationships from federation membership in labels, actions
+  and removal confirmations, including nodes with both relationships. Remove only
+  the selected relationship; describe exactly what changed.
+- Anchor removal buttons at card bottoms. Show an immediate per-action spinner,
+  prevent duplicate submissions, and show an accurate completion/error toast.
+- Measure and reduce removal latency. Verify whether an authenticated existing
+  FIPS connection is preferred; implement that priority where supported, with
+  bounded fallback and no weakening of identity or authorization checks.
+- Hide rejected, expired and otherwise resolved Nostr requests from actionable
+  lists. Prevent relay replay or stale refresh results from resurrecting them;
+  retain any history needed for diagnostics separately.
+- Give incoming peer requests useful notifications linking directly to the
+  correct Federation/Peers request and its accept/reject actions.
+- Update relationship, request, availability and operation states automatically
+  across screens without routine manual sync. Handle reconnect, missed events,
+  out-of-order replies and failed refreshes without invented success states.
+- When a request changes the 3D map layout, rotate its node to the front, top
+  centre and clearly expose the request action. Cover multiple requests,
+  completion, user camera interaction, reduced motion and mobile viewports.
+- Review complete desktop/mobile connection flows after the other work passes:
+  put useful node capabilities and actions first, reduce unnecessary navigation
+  and scrolling, and assess direct links to permitted peer Cloud files. Preserve
+  the design system, trust boundaries and meaningful loading/error feedback.
+- Qualify real reciprocal removal/requests, offline and reconnect behavior,
+  duplicate/replayed events, automatic UI convergence, notifications/deep links,
+  map positioning and responsive card geometry before claiming acceptance.
