E1E2

E1 looks more like the actual casing foundation for the central temple casing, while E2 is lower but larger and can be foundation and curb. One photo can be deceiving.
A level perimeter formed can be at first filled with limestone chips and grindings, as terrace and promenade made leveled with paving stone, or just as easily be transitioned into scaffolding for higher elevation structures.
Wonder if there is record of polished pavers being looted for castle walls in present collections ?

As usual there is more than one method of raising a whole structure, the easiest here being fill out and then encase in with E2 casing. Casing can be corbelled in over fill and leveled for service foundation or as terrace.
Some older structures have apparently been on occasion stripped and later resurfaced?
For temple and edifice, as you stated, there are convenient stages, which depending on desired height, could proceed in a facllitatory progression pinch, chock, plane and lever (bollard and pulley being a sub-class of lever).
The AE had plenty of time for improvisation and style, and Meidum reminds me of an Edsel.
