===================================================================
*** BUG TRIGGERED: BufferHelper::recordReadBarrier() barrier skip ***
===================================================================
hasEventAndAccess(eventStage=12, readAccess=0x2) == true, so the
early-return is taken and NO barrier is emitted for this read.

But the ground-truth tracker (reset on reinit) shows that since the
last initializeBarrierTracker()/write, the only dstAccessMask bits
actually emitted for this EventStage were 0x4.

mCurrentReadEvents.mAccessFlags[stage] = 0x6  <-- contains STALE bits
mPOCGroundTruthReadAccess[stage]      = 0x4  <-- correct value
stale bits surviving release()        = 0x2

Root cause: RefCountedEventArrayWithAccessFlags inherits non-virtual
release() from RefCountedEventArray which clears only mBitMask, leaving
mAccessFlags[] stale across BufferHelper::initializeBarrierTracker().
The next replaceEventAtStage() OR-accumulates into the stale value, so
hasEventAndAccess() reports a barrier that was never emitted.

Vulkan consequence: the prior write is NOT made visible to access type
0x2 at this stage -> SYNC-HAZARD-READ-AFTER-WRITE.
