/* 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
