# DSH Tauri Turn Rewind

> Review and safely undo workspace file changes made during an Agent turn.

`dsh-tauri-turnrewind` creates a private Git snapshot for each Agent turn and shows a file-change card at the end of the conversation. It never changes the user's repository HEAD, branches, index, stash, or commit history.

## User-visible features

* Show changed-file counts and `+N -M` line totals after a turn finishes.
* Undo additions, modifications, and deletions after conflict checks pass.
* Show up to three file rows with an expansion control for the rest.
* On kernels that expose the sidebar file capability, open files in the in-app preview; the Review action opens the workspace file tree.
* Hide non-actionable cards for non-Git workspaces while retaining actionable diagnostics for missing Git, unsafe paths, or expired snapshots.

## Data and boundaries

Snapshots live under `$DSH_HOME/dsh-tauri-turnrewind/` in private repositories and session ledgers. The most recent 50 turns per workspace remain undoable, and each ledger retains up to 200 records. Per-file, per-turn, and snapshot size/count limits are enforced; excluded paths are reported on the card.

Before undoing, the plugin checks for changes made after the turn. If conflicts exist, it changes no files. Non-Git workspaces, nested repositories, and excluded oversized files are outside the undo scope.

<Warning>
  Undo changes workspace files. Review conflict warnings first; this plugin is not a backup system and does not provide redo.
</Warning>

## Compatibility

The plugin chooses file-preview and Review actions from runtime capabilities rather than version strings. Older kernels hide or downgrade unavailable in-app sidebar actions instead of handing paths to the operating system.
