+// [zh] 容器读写正常化（数据容器自检 + 修复）
+// 把数据容器里每一个工具会用到的目录逐个解析、创建、然后真的建文件写一遍、fsync、读回、比对、删除。之前「容器内读写失败」的四个真实原因都在这里被点名：目录只是 URL 不是目录、isWritableFile
+// 是坏探针、容器 UUID 会变、Library/Preferences 归 cfprefsd。
+//
+// [en] Container read/write normalisation (data container self-test and repair)
+// Resolves every directory the tooling uses inside the data container, creates it, then actually
+// creates a file, writes, fsyncs, reads back, compares and deletes. The four real reasons container
+// writes failed before are all named here: a URL is not a directory, isWritableFile is a bad probe,
+// container UUIDs change, and Library/Preferences belongs to cfprefsd.
+// ── 判别 / oracle ──
+// 跑完会留下 container_health.txt。修复动作是幂等的，每次启动都会再跑一遍。
