Correction to earlier "deferred" report: after Howard pushed (5GHz needs fixing
regardless of 6GHz), I attempted width40 + non-DFS channel plan autonomously.
It did NOT validate live: 5G retry flat (8.7->8.4), 2.4 retry up (12->16) from
voice phones scattering to 2.4. ROOT CAUSE: the non-DFS channels here (149/157)
carry the heaviest EXTERNAL interference while DFS was cleaner -> forcing non-DFS
traded clean DFS for congested non-DFS. Rolled 5GHz back to baseline (channel+80MHz).
Kicked the 8 stuck Poly phones -> 6 back to 5GHz (rest are coverage-gap rooms).
End state recovered: satisfaction 98.4/med99, voice 31/31. Kept: 2b (2.4 power)
+ BSS-transition. 5GHz unchanged from start. auto_upgrade left OFF.
Doing 5GHz right needs the per-channel survey (choose channels by real cleanliness,
not non-DFS policy), reconsider non-DFS-only, 6GHz unblock (WPA3), band-steer voice.
