Snapshot a workspace: freeze its filesystem and seal its event log. The next command cold-boots from this snapshot. Checkpoints are cheap and live in git history: fork a workspace to branch off a different path, then continue work in either one.

Expose a port from a workspace to the internet. The port must be bound inside the workspace; once exposed it is reachable from a generated public URL.

Create a persistent development workspace: a filesystem and processes that survive between calls. Optionally clone a git repository into it. Returns the workspace id used by every other tool.

Stop exposing a port from a workspace.

Delete a workspace: its filesystem, its process list, and every snapshot it ever had. This is permanent and cannot be undone.

Fork a workspace: branch off a new independent copy at the current snapshot or at a named one. Both the fork and the original can be worked on in parallel; they do not interfere.
