Description
Example: Given this HLSL:
static RWByteAddressBuffer DynamicBuffer = ResourceDescriptorHeap[1];
[numthreads(1, 1, 1)]
void DynamicResources()
{
uint val = DynamicBuffer.Load(0u);
RWByteAddressBuffer DynamicallyIndexedDynamicBuffer = ResourceDescriptorHeap[256 + val &0xf];
floatRWUAV[0] = DynamicallyIndexedDynamicBuffer.Load(0);
}
There is no metadata at all for the locally-defined “DynamicallyIndexedDynamicBuffer”.

Research direction
The issue provides an HLSL reproducer for a locally declared, dynamically indexed resource but names no source file, test, or entry point. Start by locating handling for resource metadata in the compiler, then add metadata for DynamicallyIndexedDynamicBuffer and verify the supplied example reports it.
