Transparency to the pilot is not evident in this particular accident. The first reported condition was a/p loss. Why did it drop? Ordinarily, if for reasons of control limits, the a/c remains in NORMAL LAW after a/p loss. It was eleven seconds later that the pilots together noted, "So, lost Speeds".... and "Alternate Law".
Question: During their ordeal the System presented a transparent (an clear) picture to the poor guys?
They were informed why the plane "degraded". They were reliably informed they were stalling? The stall warning worked as expected by a crew badly needing reliable information? IMHO this is "little bit" closer to "partner opacity".
The "persistent NU..." (from BEA) is coherent with "transparency" from the partner to the PF?
