A second pass compared every tag, number and literal in the plan with the
field files, locally. Two borrowed values remained: a motor rating and one
motor tag. Both are now invented (18,5 kW, M82), and the dependent sums and
section rules were checked against them. The rest of the tank series was
renumbered to keep its old sort order, since several assertions compare
sorted tags: T4101-T4103, T4500 and T4600.
Docstrings no longer tie example layer names to a particular drawing. The
fixture's claim now says exactly what is invented (every tag and number) and
what is ordinary drafting vocabulary (layer and block names). The spec's
grounding paragraph now says "process plant" and no longer names the sector.
