真机 0.8.46 两个症状： 1) 开机菜单亮度 = 第一屏的 60（用户设置 1）——根因是 M6.25 的选单亮度写回只改了源码、 二进制没重编（strings 无 display.brightness_min），本次只交源码，重编交给 M43 批次。 2) HibyOS 亮/灭屏瞬间爆亮——supervisor 把启动瞬间面板读数（播放器写的 60）当保底， 且 >60 一律钉 60；扫描窗保底只要读到亮度<=0 就在 400ms 内写回该值，用户主动熄屏 也会被强行点亮。 改动（全部失败也沿用现状行为）： - saved_brightness 权威源改为 settings.conf 的 display.brightness（与 watchdog/launcher 同源同 clamp）；面板读数只在 settings 不可读时兜底；两者都不可知才写 BM_BRI_SAFE_LOW。 - 旧的 `>60 → 60` 硬钉改为 clamp 进 [display.brightness_min, max_brightness]（bm_bri_clamp）， 不再用常量顶替用户值；为什么不会重新引入 M2.9 开机闪屏写在 bm_bri_pick_saved 注释里。 - 扫描窗保底加「播放器忙（proc 态 D）+ 面板未下电（bl_power<=0）」两门，窗口结束彻底放手。 - 热键熄屏恢复：面板真实正值优先（HibyOS 内改过亮度），否则用 settings 值，夹进 [min,max]。 - 决策抽纯函数 bm_bri_pick_saved / bm_bri_clamp / bm_bri_floor_decide / bm_bri_hotkey_saved。 - 亮度判定/写回补 bm_log 落卡（stderr 原行全部保留），只在状态跃迁时打，不在高频路径刷日志。 - test_bm_fw.c：宿主单测（settings=1/saved=60/now=0/blank 矩阵 + clamp 矩阵 + 真文件 e2e）。 - -Wall -Wextra 清理：3 处 unsigned/int 比较、未用参数、未用变量、sys/poll.h→poll.h。 不含二进制、不改 fw_content.conf 钉值（保持 4441822d）。

/* test_bm_fw.c — 宿主单测：meow_bootmenu 的亮度决策（M23 亮度单一权威源）。
|
||
*
|
||
* 覆盖真机 0.8.46 两个症状的判定矩阵：
|
||
* ① 开机菜单/选单亮度 = 面板继承值 60（用户设置 1）—— 选单路径 bootmenu_settings_brightness()
|
||
* ② HibyOS 亮/灭屏瞬间爆亮 —— supervisor 起始 saved、扫描窗保底、热键熄屏恢复三处决策
|
||
*
|
||
* 编译（build_bootmenu.sh host；与 meow_watchdog 的 test_wd_fw.c 同款 include 打法）：
|
||
* gcc -Wall -Wextra -Os -I../meow_launcherd -DBM_NO_MAIN \
|
||
* -Wno-unused-function -Wno-unused-parameter -Wno-unused-variable \
|
||
* test_bm_fw.c ../meow_launcherd/meow_touch.c -o test_bm_fw
|
||
* 运行：./test_bm_fw；全 PASS -> exit 0。
|
||
* env MEOW_BACKLIGHT / MEOW_SETTINGS_FILE 把背光与 settings 指到临时文件（真机无这两个 env，
|
||
* 走 /sys 与 /usr/data 默认路径），因此这里的读写断言就是真机同一条代码路径。
