Problem

It’s not possible to branch an ongoing conversation at a specific message to explore alternatives without losing the original thread.

Context

Users often want to try a different direction mid-chat but keep the original task intact. Today you can edit/delete or restore from checkpoints, but there’s no quick way to branch. This makes iteration and comparison harder.

Desired behavior:

• From any chat message, offer “Fork from here”
• Default: create a new task that copies the conversation up to that message and leaves workspace files untouched (chat-only fork)
• Optional later: allow “Chat + Files” fork that also restores files to the last checkpoint near that point

Constraints/Preferences

• Non-destructive by default (no file changes)
• Low-friction action available directly from each message
• New task should clearly indicate it’s a fork (so users can compare branches easily)
