blueline — Pixel 3 (SDM845)

Casey's daily driver. A reprovision costs him his live system, so reaching for fastboot is a regression, not a fallback. Cold boots are his, at the device; a warm reboot poisons TZ/remoteproc state.

This page is a pointer, not a record. The canonical per-subsystem spine is ../../saf/device/ and it stays that way — one owner, one path.

subsystem	record
audio, calls, mic	`saf/device/audio.md` — read it before touching a mixer
display, panel, DPU	`saf/device/display.md`
modem, bearer	`saf/device/modem.md`
MMS	`saf/device/mms.md`
sensors, SLPI	`saf/device/slpi.md`
touch	`saf/device/touch.md`
grip / squeeze	`saf/device/edge-sense.md`
board, boot, kernel	`saf/device/platform.md`

Reaching it

ssh -i ~/.ssh/ani casey@172.16.42.1        # USB tether
ssh -i ~/.ssh/ani casey@10.10.20.234       # home wifi, via VPN
Pixel3Arch/tools/phone-triage.sh [host]    # thirty-second triage

10.10.20/24 is reachable only through WireGuard and it does not autoconnect after a reboot. The phone does join foreign networks; pass the address rather than hunting for a cable.

Delivery

pacman -Syu from the Gitea repo, kernel included. Do not flash. The three paths that reach this device are enumerated in ../../START-HERE.md §5, and picking the wrong one is why things silently never update — rootfs-overlay/ lands on a flash only, and this phone does not flash.

What the d10 proved about this body

Bring-up on a second board found three places the base assumed one phone. All three are blueline-visible and two were invisible here:

blueline-screen-toggle is the DPMS executor by name, and it ships only in rootfs-overlay/. Panel power belongs in viewtop, which owns the CRTC and runs on both.
brightnessctl set 10 is an absolute. 10/255 here is a dim panel; 10/2047 on the iPhone is black. Fixed in souveraine eb0292c as a percentage.
hyprctl is still asked for windows, monitors, layers, animations and workspaces. It is dead under viewtop on both bodies — blueline merely still has the binary lying around, so the failure is silent here.
