Gluetun does not support Private Internet Access over WireGuard (upstream:
native support "cannot be added... slow work in progress"; confirmed live
rejecting the provider on v3.40/v3.41/latest). PIA in Gluetun is OpenVPN-only.
Amend ADR-0013 to PIA over OpenVPN-UDP. The egress ARCHITECTURE is unchanged
(single shared gateway, central kill-switch/fail-closed, native PF, Cilium
egress steering, active/standby) and R-NET-05/06/07 remain met; only the tunnel
protocol changes. OpenVPN-UDP satisfies "non-TCP", and Gluetun's HTTP control
API (health + forwarded-port lookup) is what the shared-gateway topology needs.
thrnz/docker-wireguard-pia retained as a documented WireGuard fallback.
Propagated the protocol correction to all active specs: ADR-0013 (+amendment
note), decisions/README, docs/00, docs/01, docs/03, docs/07, agents/task-board.
Superseded ADR-0008/0012 left immutable as historical record.
