   after the guest reboot — confirmed in **Phase 3.3** (post-restart sys_drive still `disk--2`).
 
-## Phase 3 — server restart + retired banner — ⏳ PENDING
+## Phase 3 — server restart + retired banner — ⏳ IN PROGRESS
+
+### 3.1 — banner gone in every storage state — ✅ PASS
+- Rendered `/settings` in the current state (navidrome on flash, radarr on sys_drive, both drives
+  registered, after the 1.12 raw free-form add attempt): **0** occurrences of "aktiválásra vár" /
+  "Újraindítás most" / `activate-drives-btn` / `activatePendingDrives`. The banner is retired
+  (v0.81.0) and never appears. The "Kiszolgáló újraindítása" card is present (4 refs).
+
+### 3.2 — endpoint routing + wrapping — ✅ PASS (routing) / ⚠️ auth-gate not demonstrable on demo
+- `POST /api/storage/activate` → **404** (old route removed). `POST /api/server/reboot` is routed (202 —
+  confirmed live via the 3.3 UI click, not double-fired here). Route is wrapped
+  `RequireAuth(CsrfProtect(HandleServerReboot))` (cmd/controller/main.go:731).
+- **Demo limitation:** the demo controller has **no password set** (`authEnabled()=false`), so RequireAuth
+  + CsrfProtect are both no-ops here (`csrf.go:30` exempts when auth is disabled) — the "rejected without
+  auth/CSRF" half of the matrix can't be shown without setting a password (out of scope: changing account
+  settings). The middleware wrapping is source-verified and is the same gate every other mutating endpoint
+  uses. **Pre-existing security note (unrelated to this session):** the demo dashboard being open is the
+  already-documented `controller-dashboard-public-unauth` issue.
+
+### 3.3 — "Kiszolgáló újraindítása" (UI click → guest reboot) — ⏳ executing (operator-authorized)
+- Pre-reboot baseline: guest uptime 1:05; containers cloudflared/traefik (14:43), controller (16:52),
+  filebrowser/navidrome (17:50), radarr (17:55).
