"""verify_fixes.py — redeploy both apps on 9202 after the UPnP and host-list fixes, and prove:

  1. neither app asks the household's router for a port any more (3.x / 01 §7)
  2. the controller's probe is no longer refused for a bad Host header
  3. the lock-out is per VISITOR, not per app: a stranger's wrong tries from ONE address do not shut
     the household out from ANOTHER (checklist 3.6 + 3.10)

The third one is why this file exists: the first box walk ran the stranger and the household from the
same machine, so a shared ban could not be told apart from a per-visitor one. Here the stranger is
DooPlex (192.168.0.180) and the household is the guest itself — two addresses, one app.

Runs ON DOOPLEX, after the drill catalog carries the fixed templates.
