 Daytime re-check: CronCreate one-shot 9:33 AM 6/17 (reported session-only — NOT durable) + coord todo
 (reliable backstop) filed for Howard. Remaining: Phase 5 (5GHz 80->40 + channel) + Phase 6 (6GHz: add 6g

+## Update: 16:00 PT (2026-06-17) — daytime re-checks: interference DOWN but client experience WORSE (over-thinning) -> Low->Medium recommended. (Howard continuing in another session.)
+
+Two loaded-network re-checks (09:33 + 11:27, time-of-day controlled vs same hours yesterday at full power)
+both say the SAME thing: the 2.4 remediation cleaned too aggressive.
+
+  metric (2.4 site-wide, hourly)   yesterday FULL    now POST-change
+  interference cu_interf           65-66%            32%      <- WIN (down ~half)
+  total cu_total                   79%               44%      <- WIN
+  retry%                           17-18.5%          23-32%   <- WORSE (roughly doubled)
+  satisfaction                     39                30-31    <- WORSE
+Active-radio-only snapshot: cu_interf ~48% (vs 64 pre), retry ~22%. Fleet: 77 adopted / 2 disconnected,
+NO AP offline.
+
+DIAGNOSIS: OVER-THINNING. Power to Low (~6 dBm) is a 17 dB cut from auto(~23); combined with 24 disabled
+radios, some edge 2.4 clients now reach a farther/weaker AP -> retries up, satisfaction down EVEN THOUGH
+the air is much cleaner. The interference goal is met; the lever overshot on coverage.
+
+>>> CURRENT DECISION POINT (next action, NOT yet done):
+1. Bump the 42 KEPT 2.4 radios Low -> MEDIUM (~12-15 dBm): restores edge signal, cells still tighter than
+   full, and the 24 disables STAY OFF so most of the interference win is kept. Command per floor (skip 5/6,
+   skip mesh/offline like the power-down was):
+     bash .claude/skills/unifi-wifi/scripts/apply-radio.sh cascades ng power medium --zone "Floor 3" --apply
+     (Floor 1/2/misc per-AP, spaced ~4s, to skip mesh parents + 128/108 + login throttle)
+2. Re-measure retry/satisfaction (same time-of-day) after the bump to confirm recovery.
+3. If still high, re-enable a few of the 24 disabled radios in the weakest spots.
+
+STATE RECAP for the other session: Phase1 power-down DONE (was Low on 65; recommend ->Medium on the kept
+42). Phase3 disables DONE (24 off: 102 115 116 122 127 128 139 145 203 204 209 229 236 240 241 248 304 317

+UNTOUCHED. Phase 5 (5GHz 80->40 + channel) and Phase 6 (6GHz: add 6g to CSCNet + bss-tm; apply-wlan 6e->6g
+already fixed) still PENDING. Runbook: reports/2026-06-16-2.4ghz-remediation-runbook.md. Rollback: ng power
+auto / ng enable --ap. Friction logged: per-AP apply re-logins -> space calls.
