new-peer.sh generated MTU 1420, which stalled traffic on mobile data
despite a healthy handshake (one phone, one carrier, 2026-11-09). Default

Correct stale claims in the runbook and the DaemonSet header against
live BPF conntrack: LoadBalancer VIPs see 10.90.0.x as world, not a
SNATed host identity. Add a troubleshooting section.
The DaemonSet render is unchanged, so WireGuard pods do not roll.
