Parallel work

Start from a configured repository. Read worktree behavior for this version before choosing shared or isolated files.

git worktree add ../project-review -b review-work
cd ../project-review
hack up --detach
hack open
hack ps

Linked worktrees normally select a branch instance automatically. Confirm the selected instance and URL in the output; detached worktrees need an explicit --branch choice. Stop the instance from its owning checkout when finished. A separate branch environment does not automatically isolate external databases, shared bind-mounted files or credentials.

Coordinate with people and agents: name the checkout/branch, assign service and file ownership, and keep one owner for lifecycle operations against an instance.
