@@ -24,6 +24,7 @@ Alle Änderungen am Projekt. Format: [Keep a Changelog](https://keepachangelog.c
 - RVS: neue Message-Typen `sat_hello / sat_discover / sat_devices / sat_command / sat_result`.
 - Bridge: Satelliten-Registry (`sat_hello`) + Future-Relay (`/internal/satellite`, `/internal/satellite-list`) analog zum flux-Muster.
 - Brain: Tools `satellite_list`, `satellite_devices`, `satellite_command` + Seed-Regel, die ARIA den Ablauf beibringt (erst list, dann devices, dann command).
+- **Diagnostic: neuer Tab „Satelliten"** — zeigt live welche Satelliten verbunden sind (online/offline, Standort, Capabilities, read-only vs. steuerbar) und pro Satellit ein „Geräte scannen" (löst `sat_discover` aus → erkannte Geräte mit Typ/IP/Modell/DIAL/MAC).
 
 ### Deploy
 Satellit im Ziel-Netz: `cd satellite && cp .env.example .env && docker compose up -d --build`. Haupt-Stack: `git pull && docker compose up -d --build brain bridge` + RVS-Stack `up -d --build`. Kein APK-Rebuild.
