# Offline charging mode for the FP6 (Android-style charger boot), built
# 2026-08-24 — source of truth + design + test evidence: fp6 repo
# work/charging-mode/ and journal/power/.
#
# The FP6 ABL appends androidboot.mode=charger when a charger insertion
# powers the phone on. Without this package, that boot goes all the way to
# the full UI and at low battery sags back into shutdown — the dead-battery
# bootloop. With it, a systemd generator diverts charger boots to a minimal
# charging.target: ADSP-owned charging runs (incl. USB-PD), panel dark
# (splash killed ~6-10 s in via the initramfs hook), modem/cdsp remoteprocs
# stopped, radios/sensors suppressed, CPU capped. Verified net >= breakeven
# even on a 100 mA-classified workstation USB port; strongly positive on
# real chargers.
#
# User interactions in charging mode:
#   power key    reboot into a normal boot (warm reboot drops the ABL flag)
#   volume-up    toggle on-screen battery status (%/rate/input/ETA)
#   volume-down  enable ssh over the USB cable (debug; static 172.16.42.1)
#   unplug       orderly poweroff
#
# Suspend duty-cycling exists behind /etc/charging-mode/enable-suspend but
# is NOT shipped enabled: resume from deep suspend intermittently kills the
# UFS link (tracked in journal/power, track 3). Do not enable until fixed.
# Escape hatch: touch /etc/charging-mode/disable to make the generator
# inert. Units install under /etc/systemd/system (same paths the dev phone
# runs, byte-identical to the tested deployment).
