Howard caught a real hazard: coverage-thin was mesh-blind. At Cascades, 2nd Floor Atrium is the
wireless-mesh PARENT for CC Bridge + salon (backhaul ch36/5GHz), and 206 U7 Pro carries 108. The tool
had listed 2nd Floor Atrium / CC Bridge / 206 as 2.4 disable targets. Although the backhaul is 5GHz
(so a 2.4-radio disable wouldn't drop it), touching infra APs that feed others is needless risk.
Fix: fetch live uplink topology (stat/device); build the mesh set = wireless-uplink APs UNION their
parents; exclude them from disable (kept as coverers if their 2.4 is on); print MESH-PROTECTED line.
Falls back with a clear WARNING if no controller cred. Cascades now auto-excludes 108/206/2nd Atrium/
CC Bridge/salon; resilient plan 34->33. Also verified SSIDs are not AP-pinned (broadcasting_aps off),
so no client is orphaned by a radio disable.
