“ the code itself becomes an artifact of synthesis, not the locus of intent.”
would not be unfamiliar to mechanical engineers who work with CAD. The ‘Histories’ (successive line-by-line drawing operations - align to spline of such-and-such dimensions, put a bevel here, put a hole there) in many CAD tools are known to be a reflection of design intent moreso than the final 3D model that the operations ultimately produce.
CAD tools also really don't like changes in the history. A tiny change in one step can corrupt the entire model, because a subsequent step can no longer properly "attach" to a reference point which no longer exists.
Fixing this in CAD is already a massive pain, fixing it with black-box LLMs sounds nearly impossible.
