Hello Jon Ellison; regarding the above image you wrote:

”Not really as it isn't an arch.
It's a triangulated, opposed truss.
It functions dynamically in exactly the same way as the trusses' in the other pyramids...”


These comments are incorrect.

The roof structure for this space is an arch. It is composed of segments of opposing voussoirs. It is not a “triangulated, opposed truss”; in that it does satisfy the formulaic requirements for a truss: m = 2n – 3, where m is the total number of members and n is the total number of nodes. It does not function “dynamically” as a truss, for the same reason.
