dsh-plugin-session-rollback

In a typical DSH coding conversation, a single misguided instruction can alter files you do not want changed, and rolling back usually means manual file surgery or starting over. dsh-plugin-session-rollback saves an automatic workspace checkpoint before every real user message, then adds an Undo button next to the copy icon on each message. Clicking it removes that question and every subsequent exchange while restoring the workspace code to the exact state before the question was submitted, all within the same session ID.

Key capabilities include event-sequence-matched checkpoint lookups with no cross-turn substitution, an automatic safety backup before every restore that can be undone with /rollback-undo, SHA-256 content-addressed deduplication so identical files are stored only once, and full light and dark theme support. Original session events remain in DSH's append-only audit log; the rollback only hides them from the active Surface without deleting them.

It is built for DSH developers who iterate through many rounds of code edits and want a reliable safety net to step back to any earlier question without disturbing the work completed before it.
