Charger-insertion boots (androidboot.mode=charger, ABL-appended) divert to a minimal charging.target instead of the full UI, ending the dead-battery bootloop: ADSP charging/USB-PD runs, splash+panel killed ~6-10s in via an initramfs hook, modem+cdsp stopped, radios/sensors suppressed, CPU capped. Power key reboots to a normal boot, volume-up shows battery status, volume-down enables USB ssh, unplug powers off. Measured >= breakeven on a 100mA-classified SDP port, strongly net-positive on real chargers. Suspend duty-cycling (~13mA floor) exists behind an off-by-default flag: resume from deep suspend intermittently kills the UFS link (hibern8 exit failed ret=5) - do not enable until that kernel bug is fixed. Byte-identical to the deployment verified on the dev phone 2026-08-24 (journal/power: r5 armed tests, crash autopsies, measurements). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# FP6 offline charging (work/charging-mode): on charger-triggered boots,
|
|
# kill the boot splash and panel as early as software can — this hook runs
|
|
# right after splash_start in the initramfs (~6-10 s after power-on), vs
|
|
# the charging monitor's blank at ~16-20 s. The 0-5 s bootloader logo is
|
|
# ABL's and untouchable. Executed via `sh` by run_hooks (subshell, exit is
|
|
# safe); written to fall through harmlessly on any failure — a normal boot
|
|
# must never be affected.
