+#!/usr/bin/env bash
+# Despliega metrics_agent en un móvil Android/Termux como servicio supervisado
+# (termux-services / runit) con arranque en boot (Termux:Boot) y wake-lock.
+#
+# Uso: ./deploy_agent_termux.sh <node> <ssh_alias>
+#
+# Requisitos:
+#   - Binario en apps/metrics_agent/dist/metrics_agent_arm64
+#     (CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -ldflags="-s -w" -o dist/metrics_agent_arm64 .)
+#   - `pass fleet/ingest-pass`.
+#   - En el móvil: Termux + Termux:Boot + Termux:API instalados, paquetes
+#     `termux-services` y `termux-api`, y un alias SSH al sshd de Termux.
