 ## Observed-file state (policy plugin)
 
-Observed state is a `WeakMap<owner, Map<targetKey, FsObservation>>` held inside the `dsh-fs-policy` plugin. Missing map entry means unseen; `{ kind: 'absent' }` means a tool read/view confirmed absence; `{ kind: 'present', version }` means a read, write, or edit observed that version. The write decision maps unseen and absent to `createIfAbsent`, while present maps to `replaceIfVersion`; the edit decision maps unseen to `FS_NOT_OBSERVED`, absent to `FS_NOT_FOUND`, and present to its version guard. The owner is derived from the event actor (normally `exec.agent.session`), treated as opaque and never read. Disposal drops everything (HMR safety), and the policy performs no filesystem I/O.

 ## 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.

File views use one-based line numbers and preserve content tabs, so displayed text remains valid literal replacement input; directory views omit hidden, dependency, and Python-cache entries and descend two levels. A missing view records confirmed absence before returning `FS_NOT_FOUND`, so a later `create` can recover an externally deleted path through the mounted policy's guarded-create flow; absence never authorizes `str_replace` or `insert`. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.
