The Android client ships OpenVPN 2.7, which refuses a --secret config
("Options error: No tls-client or tls-server option"; 2.8 drops it
entirely). Rework the phone instance to a CA-less TLS point-to-point:
two self-signed EC keypairs generated on ru-vps (server.* / client.*),
each side pins the other by SHA256 with peer-fingerprint, data-ciphers
AES-256-GCM. Everything else unchanged (tcp/9444, tun2, 10.80.0.0/30,
NAT via tun0, systemd unit, shared homelab_vpn_client_routes).
Verified on ru-vps 2026-09-03: openvpn 2.6.19 starts clean ("Using
certificate fingerprint to verify peer"), listens on 9444, tun2 up,
make openvpn-phone idempotent (changed=0 on rerun), make lint green.
The regenerated ansible/generated/ada-phone.ovpn (self-contained
cert+key, gitignored) was handed to the operator.
openvpn-laptop.yml is left on static key — not deployed; needs the same
TLS treatment when someone actually uses it.
