BaseFutureSessionService

abstract class BaseFutureSessionService : SessionService

Java-friendly base for implementing a SessionService. Every method of the engine interface is suspend; this base final-overrides each and asks the Java subclass for a CompletableFuture instead. Return each future promptly and do any blocking work inside it, not before returning it. The two methods with default bodies (closeSession, appendEvent) keep those defaults reachable: leave the hook unoverridden and the engine's own behaviour runs.
