The sixth bounded contract slice introduced `IGraphicsHost` for mutable surface fill/copy, retained-range and
frame presentation, transition waits/fades, texture lifecycle, pixel capture/replace, drawing, and size
queries. `IHost` inherits the focused contract; all seventeen members, required implementations, default
fallbacks, and existing host classes remain behaviorally unchanged. Surface request records and the fade
direction remain in their prior locations pending a separate transport cleanup. Runtime validation remains
green.

## 8. Immediate next step
Continue step 3 of the **codebase consolidation** maintenance slice: clarify runtime contracts without changing
behavior or the aggregate host accepted by the VM. With diagnostic, lifecycle, audio, and movie contracts
established beneath `IHost` and shared movie/image transport now neutral, introduce the graphics host contract
next. Preserve its surface, retained-range presentation, transition, texture, capture/replace, and headless-default
behavior while leaving the remaining surface request records in place for a separate transport cleanup.
established beneath `IHost`, shared movie/image transport neutral, and the graphics contract now separated, move
the unchanged `SurfaceRectFill`, `SurfaceRectCopy`, and `SurfaceBlackFadeDirection` contracts from `Hosting` to
`Model` next. Preserve all consumers and graphics behavior before separating the remaining ADV/input domains.
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.
