/* test_wd_fw.c — 宿主单测：meow_watchdog 的「SDK 框架 App 判定」逻辑（M2.86, issue 226）。

*

* 编译：#include meow_watchdog.c（去 main 拿 wd_app_is_framework/wd_json_str/wd_framework_from_pid）。
|
||
* gcc -Wall -Wextra -Os -DWd_NO_MAIN -Wno-unused-function -Wno-unused-parameter \
|
||
* test_wd_fw.c -o test_wd_fw
|

* （meow_watchdog.c 含仅 main 使用的静态函数，宿主去 main 后须 -Wno-unused-function 静音；
|
||
* mips 目标构建不定义 WD_NO_MAIN，不受影响。）
|
||
* 运行：./test_wd_fw；全 PASS -> exit 0。
