+# =============================================================================
+# opencode-attach.sh — Attach TUI to the systemd OpenCode server
+# =============================================================================
+#
+# PURPOSE:
+#   Connects the OpenCode TUI to the running systemd server (port 4096).
+#   This ensures sessions are shared between the TUI and Telegram bot.
+#
+# USAGE:
+#   opencode-attach        — Attach to systemd server
+#   opencode-attach --omoa — Start systemd server with omoa, then attach
+#
+# WHY THIS EXISTS:
+#   - The systemd server runs on port 4096 (managed by Telegram or systemctl)
+#   - The TUI can either start its own server (separate sessions) or attach
+#   - Attaching shares sessions between TUI and Telegram bot
+#   - omoa is managed via systemd/Telegram, not from the terminal
