- B9A: read-only audit of stock LK/DT: the panel is an ST7735S 128x128 on SPI (BLSP1 QUP4, 16 MHz, mode 3, D/C GPIO116, RESET GPIO118), backlight = PM8916 MPP4 current sink 40 mA. - B9B: upstream panel-mipi-dbi with the stock init sequence as firmware; MPP4 sink via pinctrl + gpio-backlight; first light with correct colours/orientation/offsets. - B9C: fbcon (6x8, 21x16) on tty1 + getty, UART console kept, aurora-display service; cache B9C b9ce13c9 written and verified, cold boots with LTE + Wi-Fi + display. - B9L (RAM only): lk2nd second stage with an msm8916 SPI panel port shows a picture before Linux. - Sanitizer: whitelist for b8/ and b9/.
