🟡 (14:56) User confirmed drop-in install completed successfully ("done")
🟡 (14:56) Verification results: drop-in ExecStartPost hook present in unit ✓; AdvertiseServices: ["svc:opencode"] auto-set after restart ✓; HTTPS 200 (0.048526s) ✓; HTTP 200 (0.004632s) ✓
🟡 (14:56) Persistence confirmed: svc:opencode auto-advertises on every tailscaled start (reboots, restarts, crashes) via systemd hook running as root — no manual intervention needed
🟡 (14:56) Known edge case: tailscale up (interactive re-auth) wipes advertise pref at runtime and does NOT trigger the hook — workaround: sudo systemctl restart tailscaled or sudo tailscale serve advertise svc:opencode directly
