+### 9 — Frontend Session Routing + Live Revocation Polling
+
+- Implemented token-gated frontend flow: `/` now validates + prepares link sessions and redirects to `/session` only after orchestrator preparation succeeds.
+- Added explicit failure routes for invalid access and terminated sessions (`/unauthorized`, `/session-ended`) with reason-based messaging.
+- Added session runtime polling (2s interval with forced query refresh + network failure tolerance) that ejects users immediately when link validity is lost.
+- Extended link resolve payload with server-built ws-scrcpy stream URL data so the session route can render the active stream without exposing raw device details in the URL.
+
+### 10 — Frontend De-Branding Cleanup
+
+- Removed temporary `IOTAM` label text from session loading and failure pages to keep user-facing frontend copy generic.
+
+### 11 — Admin Link Copy Full URL
+
+- Refactored admin links-page copy action to copy full public frontend access URLs (`PUBLIC_FRONTEND_URL?token=...`) instead of raw tokens.
