Function build_faulty_object_store 

pub fn build_faulty_object_store(
    cfg: &ObjectStoreConfig,
    policy: FaultPolicy,
) -> Result<Arc<FaultInjectingStore>, ObjectStoreError>

Build the store cfg selects and wrap it in policy.

Testing seam. This exists so a fault drill can hand a misbehaving store to code whose only entry point takes an Arc<dyn ObjectStore>. The broker’s serving path never calls it; crate::build_object_store is the builder that does.

Errors

Whatever crate::build_object_store returns for cfg.
