Firecracker kernel lane recorded by the runtime artifacts; the opt-in FUSE lane
is documented in Template kernel selection.
Concepts
The Nullspace sandbox lifecycle and runtime primitives.
Nullspace sandboxes are isolated microVM runtime environments with a small set
of explicit lifecycle primitives: Create starts a sandbox, Exec runs work inside
it, Hibernate pauses state for resume, reusable snapshots capture durable
1-to-many baselines, Fork branches live state into a child sandbox, and Destroy
tears a sandbox down.
Fork is the differentiator for live branching. Reusable snapshots cover the
durable baseline case: capture setup once, then start many independent
sandboxes later.
