REVISION

A revision to a last moves every panel.

Changing a last changes everything cut and lasted against it. A revision that looks local is a revision to the whole shoe.

Why the panel impact column belongs here.

Because a last change is never local. A revision that leaves the drawing valid and the patterns invalid produces a shoe nobody can reproduce, and the error surfaces at the lasting bench rather than in review.

The habit worth copying.

Recording which last revision a size run was graded from. Without it, a run sits between two lasts and nobody can say which shape it was built to.
