design_options:
  A_backend_calls_host_systemctl_directly: recommended=False reason=Usually wrong from Docker container unless host systemd/socket is deliberately exposed; inventory did not confirm existing safe host-systemctl bridge.
  B_backend_writes_trigger_file_host_systemd_path: recommended=True reason=Simple event trigger if backend has shared bind mount to /opt/wg-access or a dedicated trigger directory. Needs exact mount confirmation and code insertion after commit.
  C_postgres_notify_host_listener: recommended=False reason=Clean event-driven model but more moving parts; good later if file trigger is unsuitable.
  D_small_host_job_watcher_polling: recommended=False reason=Reliable fallback but reintroduces polling; acceptable as watchdog, not primary happy path.
  E_enable_existing_agent_timer_as_primary: recommended=False reason=Contradicts desired event-driven contract; useful only as temporary safety if no trigger exists.
  F_reconcile_on_boot_plus_safety_timer: recommended=True reason=Needed because VM100 peers are runtime-only and UCI remains empty by design.

next_steps:
  - 042C implement chosen event trigger.
  - 042D implement explicit reconcile service/timer.
  - 042E happy-path create without manual agent start.
  - 042F VM100 reboot/reconcile recovery test.
  - 043 harness boolean contract fixes.
