Answers "which 2.4 radios can we turn OFF given over-coverage, based on AP proximity." Greedy
dominating-set on the AP-to-AP 2.4 SNR layer: disables radios whose area stays covered by a nearby
ACTIVE-2.4 neighbor, maximizing interference-airtime removed without opening a 2.4 hole. Caps per-zone,
guards coverer capacity, flags single-coverer (low-resilience) disables, reports co-channel before/after.
Why separate from optimize-radios: optimize uses band-AGNOSTIC physical adjacency, so it counts an AP
whose ng radio is DISABLED as a "coverer" via its 5/6 GHz (observed: it proposed disabling 127/229/330/428
"covered by 128" — but 128's 2.4 is already disabled => those would be 2.4 holes). coverage-thin uses the
2.4 SNR layer specifically and only counts neighbors whose 2.4 stays ON.
Cascades (live): aggressive MINCOV=1 -> disable 36/76; resilient MINCOV=2 -> disable 34/76 with >=2 active
2.4 coverers each; co-channel ch6 28->13, ch11 25->13, ch1 20->13; ~2400 interference-airtime pts removed.
