The NTSB has stated that fan blade 13 is missing. That's not simply missing from the hub, it's gone and they cannot find it. To me, that's uncontained.
But that isn't what the design designation means. The containment ring did its job and prevented the separated blade from exiting the engine at 90 degrees. The investigation now is to discover why there was a catastrophic failures of the nose cowl assy.
