真机实测：设备充电中但 battery/status 恒 Discharging；权威源为 mp2731-charger/status（Charging/Full），回退链 fusb302-typec-source/online==1 → 旧逻辑 battery/status==Charging || ac/online==1。电量仍读 battery/capacity。 - meow_svc_power: battery/status 命令充电判定走权威链（MEOW_PS_DIR 可重定向供宿主自测）； svc_power_authtest 补 6 用例（mp2731 Charging/Full/Discharging + 两级回退）全 PASS - SDK meow_ui_sys: 状态栏充电态同权威链 - launcher util.c: 抽 batt_is_charging() 公共判定；meow_sys_light 1s 轻刷补充电态（插拔实时） - bootmenu 无充电判定（仅读 capacity）/MeowPanel 透传 power 服务：均无需改 - 真机验证（充电窗口）：新二进制 battery=88%(Charging)，对照固件内旧版 88%(Discharging) - hello/files/ncm 随 meow_ui.a(af6703f2) 重链已热更到卡（.new+mv，md5 对核一致） md5: meow_svc_power 39ae3aa2 / meow_launcherd 2aa61780 / hello 2444c151 / files 691db88b / ncm 89da63ed（仅重链，源码未动）

/* svc_power_authtest.c — meow_svc_power II 期 IPC 鉴权逻辑 宿主自测（本程序非生产代码）。
|
||
*
|
||
* 通过 #include 生产源文件（meow_svc_power.c，用 #define main 改名避免入口冲突），在同一 TU 内直接
|
||
* 访问其 FILE-STATIC 函数 classify_exe / is_system_action / is_sys_identity / is_read_level，
|
||
* 验证鉴别/分级策略的决策表。
|
||
* 覆盖「真机需特权路径 /proc/pid/exe 判定」之外的所有纯逻辑分支；真实 pid→exe 解析留真机验证。
|
||
*
|
||
* 用途：dev docs 复现级宿主自测；不进入固件/不部署。用法：
|
||
* cc -Wall -Wextra -I../meow_launcherd svc_power_authtest.c -o svc_power_authtest && ./svc_power_authtest
