Trap: a persistent 50-tailscale hook looks correct because networkd-dispatcher reruns it, but it targeted obsolete enp1s0 while default traffic used br0, leaving rx-udp-gro-forwarding off. Fix: run /usr/sbin/ethtool -K br0 rx-udp-gro-forwarding on rx-gro-list off from the executable routable hook, then verify both flags and Tailscale health.
