🔴 [H4] 缓存指纹太弱 → 中间修改检测不到

审核结论：关闭（风险极低）

技术缺陷确认属实：compute_file_hash（core/io/index_cache.rs:63）确实只采样 head 4KB + tail 4KB + file_size，中间区域不参与指纹计算。

但实际风险极低： -…

🔴 [H2] mmap 与索引构建之间存在 TOCTOU 竞态

修复方案

根因: FileReader::open() 和 reload() 中，mmap 映射（快照 A）和 LineIndex::from_reader(BufReader) （快照 B）是两个独立的文件读取操作。如果文件在两步之间被外部修改，索引偏移量…

b6e655bff6 fix(io): handle file shrink in update_for_append to prevent SIGBUS

🔴 [H1] 文件缩小后 mmap 未处理 → SIGBUS 崩溃

Fixed in b6e655b.

Root cause: update_for_append() returned Ok(0) when new_size <= old_size, leaving a stale mmap that would SIGBUS on access.

Fix: Introduced AppendStatus enum (`Unchanged…
