Nix-heavy — hold one of the `buildSlots` permits for the node's duration:
| Node | Wraps |
| ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `Prebuild` | `lifecycle::prebuild_toplevel` — build the toplevel out-of-band while the container keeps serving (its meta preamble is the upstream `MetaSync` node). Skipped when the container is already down; `Swap` builds inline instead |
| `Swap` | drop-in rewrite + `nixos-container update` profile-swap (requires the container stopped); the post-swap bookkeeping tail lives in the sibling `RebuildBookkeeping` node |
| `Create` | first-spawn `nixos-container create` proper; assumes the upstream `Provision` node already registered the agent; builds from the `internal/meta` commit it resolves and marks the agent's pins |

Cheap — no build slot:
