## Observed state is the prior-observation record; freshness is provider CAS
Observed state is a weak owner-to-target map with three logical states: unseen, confirmed absent, or present at a version. A successful file read or mutation records presence; a `read`/`view` metadata miss records absence before returning `FS_NOT_FOUND`. The plugin performs no filesystem I/O: it converts that state into a provider guard. Presence supplies the observed version, while absence lets only a `createIfAbsent` write proceed; edit has no version basis and returns `FS_NOT_FOUND`. A windowed read observes the whole file version, so a later targeted edit is allowed only while that file remains unchanged. State is discarded on plugin disposal and is not persisted across sessions.

## 已观察状态是先前观察记录；新鲜度由提供方 CAS 保证
观测状态是一张以所有者为弱键、记录各目标的映射表，具有三种逻辑状态：未见、确认缺失、存在于某个版本。成功读取文件或变更会记录存在；`read`/`view` 的元数据未命中会在返回 `FS_NOT_FOUND` 前记录缺失。插件不执行文件系统 I/O：它把该状态转换为提供方防护。存在状态提供观测到的版本；缺失状态只允许 `createIfAbsent` 写入继续，edit 因没有版本基准而返回 `FS_NOT_FOUND`。窗口读取会观察整个文件的版本，因此只有文件保持不变时才允许后续的定向编辑。插件 dispose（资源释放）时会丢弃状态，并且不会跨会话持久化。
