#### Sprint 28: Remote Management (Week 5-8)
- [ ] **REMOTE-01** — Implement Tailscale-based remote access. Build on the Tailscale integration from Year 2. Add `remote.setup` RPC that: generates Tailscale auth key, configures tailscaled, exposes only ports 80/443 over Tailscale network. **Acceptance**: Can access Archipelago UI over Tailscale from mobile.
- [x] **REMOTE-01** — Implemented Tailscale-based remote access. Added `remote.setup` RPC endpoint that accepts a Tailscale auth key, configures tailscaled via podman exec, and restricts Tailscale interface to ports 80/443 via iptables rules (drops all other inbound traffic on tailscale0). Returns Tailscale IP, hostname, and remote URL for UI display.
- [ ] **REMOTE-02** — Add mobile-optimized remote management. Ensure all critical operations work well on mobile: app install/start/stop, system status, backup trigger, health check. Test and fix any mobile-specific issues. **Acceptance**: All critical operations functional on mobile Safari/Chrome.
