Interface LaravelUi5\Sdk\Action\Contracts\SdkActionHandlerInterface

The enterprise action handler — a fixed, typed contract. It extends Core's marker ActionHandlerInterface (so it is what Ui5ActionInterface::getHandler() names) but, unlike Core's handlers, whose params vary and are method-injected, it fixes them.

The signature reads as a sentence — handle(what I seal, what I was given, who I am): the outcome:

handle(BusinessTransaction $transaction, // what I seal — outcome + messaging BusinessContextInterface $context, // what I was given — validated inputs SdkContext $sdk): ActionResponse // who I am for — actor / org / abilities

Because it references BusinessTransaction and SdkContext — types Core (stateless) is forbidden to know — this contract is inherently SDK and could never be a Core signature. Fixing the params lets PHP enforce params and return natively; no invoker reflection.
