+# ProxMenuX - Upgrade PVE 8 → 9 (Simplified, per official guide)
+# ==========================================================
+# Author     : MacRimi
+# License    : MIT
+# Version    : 1.9
+# Updated    : 2025-08-10
+# Description:
+# - Automates the official upgrade from Proxmox VE 8 to 9 (Debian Trixie).
+# - Spinner-safe UI: each msg_info is closed by msg_ok/msg_warn/msg_error.
+# - Choose run mode at start: Interactive, Interactive (Expert), Unattended.
+# - In ALL modes, output is streamed to terminal; Unattended shows everything but asks nothing.
+# - Cluster-aware pre-upgrade (auto/manual).
+# - Ceph handling: enforce 19.x (Squid) only if hyper-converged (flags to relax).
+# - Default repositories: no-subscription (enterprise only if --enterprise).
+# - Enterprise repo fallback: detect 401 and switch to no-subscription if needed.
+# - Pre-flight guard: simulate upgrade to ensure 'proxmox-ve' is not removed.
+# - After upgrading to PVE 9, disable translate() to avoid Python/googletrans issues.
+# ==========================================================
