# Raw output - bootstrap the root actor in a bindspace

The human deferred multiprocessing descriptor transport, selected root
namespace bootstrap as the next Layer C stage, approved enter/restore
semantics and public `tractor.net` composition, and authorized
implementation.

## Generated code

> `git diff HEAD~1..HEAD -- tractor/_root.py tractor/spawn/_netns.py`

Add an optional realized `Bindspace` to `open_root_actor()`. Duplicate
its namespace FD, enter before debugger, registry, IPC, or runtime
startup, and restore the caller thread's original namespace after root
teardown. Preserve caller FD ownership and primary errors across
restoration and close failures.

> `git diff HEAD~1..HEAD -- tests/test_netns_spawn.py tests/net/test_wg_iface_lifecycle.py docs/api/net.rst`

Exercise same-netns behavior, body errors, cancellation, restoration
failures, missing and closed FDs, real root entry/restoration under an
unprivileged user namespace, and public WireGuard-bindspace/root
composition.
