Yes, Erik's thesis is a great resource, but IIRC it only explains the
first part of the process in detail, and only briefly mentions the
role of the engravers.

There is no mention of the order-of-operations within an engraver, the
acknowledging process, the grob->stencil conversion, etc.

(Yes, I plan on eventually documenting all of this in the CG once I
figure it out.)
