The fourth bounded `VirtualMachine.Step` extraction moved retained-object registry queries, default-slot and
geometry mutation, direct and embedded-range transforms, clone, and erase dispatch into
`engine/Age.Engine/Vm/VirtualMachine.RetainedObjects.cs`. The top-level dispatcher retains all labels at their
existing positions and routes the separated groups through `StepRetainedObject`; timed/cyclic animation,
color, surface release, ADV binding, and presentation behavior remain outside this handler. Runtime validation
remains green.

Continue step 2 of the **codebase consolidation** maintenance slice: behavior-neutral physical splits backed
by the tracked launcher and layered validation driver. With the planned `Main`, `GodotAdvHost`, and `GfxState`
domains isolated and the audio, movie, and surface/texture `VirtualMachine.Step` families routed through domain
handlers, extract the retained-object query/mutation and transform opcode family next without replacing the

Concrete playthrough blockers may still preempt this bounded maintenance work; the consolidation effort does
not replace Phase B gameplay validation or the open cross-platform gates.
