A safe - migration helper (clear TOTP rows that were never user-activated) would be a Crafty-side or - entrypoint concern — own task; currently moot (no other installs). -2. **Java 25 present** → no custom image needed to run latest MC; the earlier "may need a custom - temurin-25 image" worry is resolved by 4.10.7 itself. -3. **Dynamic connection panel**: render the live LAN IP + published range + per-server port on the app - page (vs static guidance) — a controller feature, own task. -4. **Bedrock (UDP 19132)** — out of scope; own task if Bedrock enters product scope. -5. **Internet exposure** (operator port-forward vs Felhom-operated relay vs Tailscale) — open design call. +## 5.
