P2-1 时长解析：后缀乘数只作用在整数部分，nsec 没跟着乘。 0.05m 被算成 50ms（应 3s）、1.5m 算成 60.5s（应 90s）、0.5h 算成 0.5s。 修法：sec 与 nsec 都乘 mult（各自带溢出检查，mult==1 行为不变）。 --help 与头注释的示例改为逐个标出等价值（2.5s=2.5s、1.5m=90s、0.5h=1800s）， 不再留文档写着、实际算错的例子。 新增 T11：宿主上编译 parser 单测（27 例，含 0.01m/0.05m/1.5m/0.5h）真跑， 并单独点名评审抓到的三条，防止回归。 P2-2 文档数字：§2 产物表 47 708 → 49 676，合计 2 189 472 → 2 191 440； 全表按 MANIFEST 重核（其余七项未漂移），§11.1 补上新的体积/md5/sha256。 P2-3 信号失败不静默：新增 kill_child()（kill(-pgid) 失败时 ESRCH 视为组已消失， 退化为 kill(pid)，EPERM 等明确告警）、verify_process_group()（发信号前用 getpgid 核对建组是否生效）、父进程 setpgid 的异常 errno 告警；连兜底 kill 都失败时退出码 125 而不是谎报 124。新增 -DTIMEOUT_TEST_SETPGID_FAIL 故障注入 与 T12（a-d）验证告警路径可达且兜底真的杀掉子进程。 真机复验（md5 aded39e0，49 676 B）：124/137/0/孙进程清零/保证挂住的命令 3.01s 被 124 结束/0.01m=0.61s、0.05m=3.01s、2.5s=2.51s/无参 125；收工 bt=0 sleep=0， Music 199164544。回归 44 通过 0 失败。

# test_build_devkit.sh — build_devkit.sh 的回归测试（不重编）
|
||
#
|
||
# 耗时：热缓存约 15 秒；若需冷启动基线重建（首次运行/源码未缓存）约 1–2 分钟。
|
||
#
|
||
# 覆盖：
|
||
# r1 P1 回归点 —— stamp 命中（跳过编译）时，--with-sources 必须真正产出 src/
|
||
# r2 P2-1 —— licenses/README 被删后 --with-sources 必须恢复，
|
||
# --verify-only 必须拒绝缺许可证的交付
|
||
# MANIFEST 内容漂移检测、src/ 缺文件与内容漂移自愈
|
||
# M53 —— 本地源码路径：timeout 产物存在/静态/MIPS32r2/零 NEEDED、
|
||
# MANIFEST 有 Apache-2.0 行、license 原文随附、
|
||
# 源码纪律（独立实现、不调 clock_gettime、不用 timerfd、setpgid+kill(-pgid)）
|
||
# M53 r2 —— 时长解析真跑回归（宿主编译 parser，覆盖 0.01m/0.05m/1.5m/0.5h）
|
||
# 与信号失败告警路径（注入 setpgid 失败，必须告警且兜底 kill(pid)）
|

#
|
||
# 前置：MEOW_DEVKIT_WORK 里已有一次构建（脚本会先跑一次增量构建，命中则秒回；
|
||
# 缓存缺失时会联网下载/编译，第一次运行约 1 分钟）。
|
||
#
|
||
# 用法：bash scripts/build/test_build_devkit.sh [-v]
|

# 退出码 0 = 全过；非 0 = 用例失败数。
