M29 只解决了「回书架不重扫」；首次进书架仍要全量扫 434 目录（真机 3.0–3.4s， 其中 opendir+readdir 占 96%）。本单把扫描结果 + 每个扫描目录的 mtime 存到 MeowData/os.meow.reader/index/shelf.idx，冷启动逐目录 stat 比对 mtime，命中即 完全跳过 readdir；任何异常一律 fail-open 全量重扫。 先量再选（任务 1）：宿主 434 目录/595 本/51 rar 虚拟库（贴真机量级） - 434 次目录 stat = 0.48ms/pass（1.1µs/次，不含 readdir）； - 读 72KB 索引 = 0.009ms；全量扫描 3.54ms；索引命中 1.29ms（ts_fn=NULL）。 真机按 M28 实测 1079 次 stat=160–170ms（≈150µs/次）外推：434 次 ≈ 65ms， 远低于「可能不可行」的 1s 阈值 → 选「校验全部扫描目录 mtime」（非只 level-1）。 strace 断言：indexonly 载入 0 次 getdents64、恰好 434 次 stat（真的没 readdir）。 生产路径 ≈ 65ms(stat) + <20ms(索引读) + 40–50ms(rdprog×595) + <20ms(build_rows) ≈ 0.13–0.15s（对比 3.0s）。 索引格式 v1（手工小端序列化，不依赖结构体布局）： header(magic/version/header_size/root_len) + root + dir 记录×(rel,mtime_s, mtime_ns,books_here) + book 记录×(rel,size,fmt) + trailer(ndirs,nbooks,flags, depth_skipped,crc32,magic)。truncated/depth_skipped 存在 flags/字段里，载入时 如实重建提示条；**不存阅读进度 ts**，载入后每本由 rdprog_load 现读再排序。 失效语义（存每个扫描过的目录，不只 level-1）： - level-2 新增 / level-3 深处新增 / 删书 → 该目录 mtime 变 → 重扫； - 一级目录改名 → 父目录 mtime 变 + 旧目录 stat ENOENT → 重扫； - 超深（>6 层）未扫描子树不在索引内，其内部变化不自动失效（本来就不显示）， 点「刷新」更新 depth_skipped 计数；mtime 精度受限（exFAT 10ms/FAT32 2s）的 同刻度变更也可能漏判，点「刷新」必可纠正。 M29 语义不变：首次进书架=索引或全扫；回书架=不扫；刷新=删索引+全扫（之后原子 写回新索引）。 安全/健壮（宁可慢不可错）： - 写：shelf.idx.tmp 全量写完（尽力 fsync）后 rename；中途被杀只剩 tmp，正式索引 要么旧要么完整新；rename 覆盖失败先删旧再改名；fflush/写错即放弃，绝不影响书架。 - 读：O_NOFOLLOW|O_NONBLOCK + S_ISREG（FIFO/符号链接直接拒绝不阻塞）；CRC32 覆盖 全部记录；rel 做绝对路径/“..”/内嵌 NUL/长度校验；版本/根路径/计数/逐目录 mtime 任一不符即重扫；载入崩溃路径全部 goto 清理，不改书架可用性。 - writer_open 失败（卡满/写保护/无 MeowData）→ 扫描不采集目录、照常出书； commit 失败（含只读目录 rename 失败）不留正式索引。 测试：test/shelf_index_smoke 154 pass（含四种变更场景失效、截断/字节翻转/垃圾/ 缺失/FIFO/符号链接/版本不符/根路径不符、ts 现读、truncated/depth_skipped 重建、 只读目录写失败、空 Books、root 缺失、.tmp 残渣），ASan+UBSan 干净； test/shelf_index_bench 模拟 434 目录/595 本/51 rar：scan/load 均 595 本、 truncated=0/depth_skipped=0、索引 72,156B。build_reader.sh 全绿 0 warning （core 6846 / seg 19 / chapter 71 / shelf_group 63 / index 154 / font 14 / loaders PASS）。shelf_bench_ondev 增加 index_load/scan_save 计时与 MEOW_BENCH_IDX=miss（真机首开命中 vs 未命中对比，待有卡复核）。 交付：app.json 0.1.4/code5 → 0.1.5/code6；reader md5 df4cadcf 1,711,924B；mpk md5 fec7b1bb 814,535B；未签名不推卡。

/* test/shelf_index_smoke.c — M32 书架索引宿主单测（纯 C，无设备/SDK 依赖）。
|
||
*
|
||
* 覆盖：
|
||
* I1 全量扫描 → 写索引 → 载入：书数/书名/分组/path/fmt/size/ts 全部与扫描一致
|
||
* I2 载入不缓存阅读进度：同一索引换 ts_fn 再载入，ts 立刻反映新值（含真实 rdprog 文件）
|
||
* I3 四种书库变更都必须失效（fail-open 重扫）：
|
||
* level-2 新增 / level-3 深处新增 / level-1 目录改名 / 删书
|
||
* I4 坏档 fail-open：截断 / 中间字节翻转 / 垃圾内容 / 文件缺失 / 索引路径是目录 /
|
||
* 版本不符 / Books 根路径不符 —— 一律返回 0，不崩
|
||
* I5 truncated / depth_skipped 如实重建（索引里存了这两个值）
|
||
* I6 写盘失败不影响书架：索引目录不可写时 writer_open 返回 NULL、扫描照常出书；
|
||
* commit 失败不留下半截索引
|
||
* I7 空 Books / Books 不存在：空索引可载入；root_missing 不写索引
|
||
* I8 载入路径不做 readdir（由 build 验证步骤用 strace 另行断言）
