+## Update: 2026-06-16 13:12 PT — FIRST PRODUCTION CHANGE: Floor-4 2.4 power-down pilot + 445 outage/recovery learning
+
+Baseline captured (Floor-4 2.4: 15 radios, avg cu_total 86%, avg retry 13.2%; AP 434 ground-truth 94%
+busy / hears 48 managed APs on 2.4). Applied: `apply-radio cascades ng power low --zone "Floor 4" --apply`.
+RESULT: 14/15 radios -> 6dBm (from ~23), clients retained (118 vs ~119) - no coverage loss. Rollback saved.
+
+INCIDENT: AP 445 lagged (config=low but radio stayed 23dBm). Tried device-control 'provision'
+(cmd/devmgr force-provision) to nudge -> HTTP 400 AND it took 445 fully OFFLINE; Howard physically
+power-cycled the switch port to recover. 445 back online (booted to 30dBm; config still low, not converged
+- left alone, harmless).
+
+FIX (Howard's directive - power-cycle the port is the recovery):
+- REMOVED 'provision'/force-provision from device-control.sh (unsafe on U7-Pro; refuses now).
+- ADDED 'poe-cycle <ap-name|mac>' - resolves AP uplink_mac + uplink_remote_port, POSTs cmd/devmgr
+  power-cycle {mac:switch, port_idx} = remote PoE port cycle (the controller equivalent of re-seating the
+  cable). Dry-run validated (445->Switch 4th Floor p7, 434->p5). errorlog.md updated. Coord -> Mike.
+
+EXPECTATION SET: 2.4 cu_total won't plummet (channel is foreign-dominated, ~33k BSSIDs); power-down's win
+is cell-shrink + reduced SELF-interference + better client SNR, seen in retry%/consolidation over ~10-15
+min, and it sets up the Phase-C disables. Next: settle ~15 min, re-snapshot Floor-4 retry% for before/after;
+decide on 445 (poe-cycle to apply low, or leave). Disables (445/428) still HELD.
