createAllocation abstract method
Mints the Allocation that holds this capability's live effect — the
createRenderObject analogue (ADR-0009 D4). Synchronous + cheap; the Host
then drives it asynchronously (startOrAdopt/update/dispose/detach).
ProcessCapability/ServiceCapability supply defaults, so an existing
capability needs no change; an asset overrides only to customize adopt/
detach/update for a bespoke effect.
Implementation
Allocation createAllocation(AllocationInputs inputs);
