B8A audit, B8B Pronto remoteproc (fixed wcnss_mem 0x8b600000), B8C stock NV (fixes Pronto startup watchdog), B8D cfg80211/mac80211/wcn36xx -> phy0/wlan0, B8E wlan0 up + WPA2/CCMP test AP, B8F eMMC cache 857c9c30 with aurora-wifi autostart: 3/3 class-A cold boots, AP up 76-94 s after power-on, LTE unaffected. PSK, NV and PSK-bearing images are not published.
