Owner

From spec/multi-agent-support/agent-feature-survey.md — finding #1.

What it is

A visual timeline of every state the conversation has been in, with the ability to name a point ("before refactor") and revert to it with one click. Reverts are surfaced as first-class UI, not a CLI command.

Seen in

Windsurf/Cascade ("Named Checkpoints and Reverts").

ocman angle

OpenCode already has /undo / /redo at the prompt level. We have every message+part in the SQLite DB, so we can render a timeline view per session showing each prompt as a checkpoint. Users can name a checkpoint from the UI; the name lives in ocman's state.db keyed by (platform, session_id, message_id). Revert calls OpenCode's existing undo path.

Effort

M. Storage + new view; revert plumbs into existing OpenCode CLI commands.
