**Progress (2026-08-03):** the first bounded contract slice introduced `IDiagnosticHost` for recoverable

## 8. Immediate next step
Begin step 3 of the **codebase consolidation** maintenance slice: clarify runtime contracts without changing
behavior or the aggregate host accepted by the VM. Start with a bounded interface-only slice that introduces
diagnostic and lifecycle host contracts beneath `IHost`, preserving current default implementations and existing
host classes before separating the larger ADV, graphics, audio, movie, and input surfaces.
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 and lifecycle contracts established beneath
`IHost`, introduce the audio host contract next as the smallest remaining self-contained domain, preserving every
required/default member and all existing host implementations before tackling interdependent ADV/input/graphics
surfaces.
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.
