真机 dmesg 实锤：OOM Kill ncm (score 460, anon-rss 26.9MB, 设备 56MB)。 画像：封面全分辨率 RGBA 8.28MB(1448x1448 原生解码驻留) 是最大可控块。 瘦身（按收益排序）： 1. sdk meow_ui_img 新增纯增量 meow_img_downscale + cover.c cover_cap(≤480px) → 封面 8.28MB→0.78MB，-7.65MB（mem_sim 实测 PASS）。 2. ncm_api.c 瞬态响应 rbuf：song_url→64KB、lyric/song_detail/cloudsearch/user_playlist→256KB （detail/track_all 保 1MB）。 3. ncm_app_internal.h 新增 ncm_thread_create（显式 128KB 栈），替换全部 14 处 pthread_create。 4. 滑动窗口/meta 复核零回退（window_sim：608B/首，6000 首 280KB 恒定）。 验证：mem_sim 封面收益 PASS + host home/player 渲染 OK + stream_sim/player_flow_sim/ window_sim/search_sim/cache_evict_sim 全 PASS + test_ncm_core host+mipsel(qemu) PASS + build_ncm.sh -Wall -Wextra 0 warning。真机 scp 播放在跑确认（缓存曲，0 播放请求）。 新 ncm md5 44fa16fe（text 1015150/bss 1362500）。正式部署留主会话。

# build_ncm_host_mem.sh — 宿主编译 ncm 的真实页面/逻辑（离屏 480x720）+ 内存测量 harness。
|
||
#
|
||
# 与 build_ncm_host.sh 的差异：
|
||
# * 复用既有 out/host/sdk_*.o（SDL 层既有对象，避免 SDK meow_ui_gfx.c 当前工作区
|
||
# 的注释语法缺陷导致全量 SDK 重编失败），仅重编 meow_ui_img.c（新增 meow_img_downscale）。
|
||
# * 用途：验证封面降采样（内存瘦身）在宿主按预期工作；供 mem_sim 报告各场景 RSS。
|
||
# 运行：MEM_SIM=1 ./ncm_host（内置内存自测）或 NCM_PAGE=home MEOW_UI_DUMP=/tmp/home.ppm ./ncm_host
