11. Clean Up Combatants

Object ids are Flexweave handles. When an object leaves the runtime, the caller decides which object-keyed stores should be cleaned.

The example destroys the enemy through ObjectDestroy and registers the stores that should remove enemy state:

ObjectDestroy::new(enemy).run_streaming(
    ObjectDestructionDriver::new(&mut objects)
        .with_store(&mut profiles)
        .with_store(&mut factions)
        .with_store(&mut current_health)
        .with_store(&mut effects),
    |event| effect_events.push(event),
)?;

The destruction succeeds only if the object id is live. After cleanup, checked runtime paths reject the destroyed id.
