+## Update: 2026-06-16 00:58 PT — band-steering field FOUND + wired into apply-wlan (validated)
+
+Modern UniFi (Network 8.x) has NO classic 'bandsteering_mode'. Located its replacements by inspecting
+wlanconf + the setting collection (no UI toggle needed this time):
+  no2ghz_oui              -> the band-steering toggle (keep 5GHz-capable OUIs off 2.4)
+  wlan_bands (["2g","5g"]) -> per-WLAN band membership (set ["5g"]/["5g","6e"] to force clients up)
+  bss_transition          -> 802.11v BSS-TM
+  roaming_assistant_na_*  -> 5GHz sticky-client kicker
+  fast_roaming_enabled    -> 802.11r (left out — risky for IoT/medical)
+
+Wired into apply-wlan.sh as actions: bandsteer (no2ghz_oui) | bands (wlan_bands) | steer
+(roaming_assistant) | bsstm (bss_transition), alongside minrate. Validated on the 0-client Green Valley
+WLAN: bandsteer on->verify->off, bsstm toggle, bands 5g dry-run; restored to original (bss_transition=true).
+
+Also surfaced setting.radio_ai (Channel AI: channels_na includes DFS, ht_modes_na=20/40, enabled=false)
++ setting.connectivity — possible future apply targets (pin the channel plan).
+
+WiFi APPLY SURFACE NOW COMPLETE: apply-radio (power all-states/width/channel/minrssi/disable/enable,
+--zone/--ap) + apply-wlan (minrate/bandsteer/bands/steer/bsstm, --wlan), all gated + rollback +
+validated on 0-client sandboxes. Coord: this msg. Remaining (ROADMAP C): switch/PoE + gateway collectors.
