The fifth bounded contract slice moved the unchanged, format-independent `RgbaImage` record from the SYS4 AGF

the neutral image contract; image-only format imports were removed while genuine SYS4 consumers retained
theirs. Decoder and image behavior remain unchanged, and 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 the movie-mask request now neutral, move the format-independent `RgbaImage` record
from `Sys4` to `Model` next. Update its consumers without changing the record or decoder behavior, removing the
aggregate host's image-only dependency on the format namespace before separating larger host domains.
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.
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.
