The reconcile pass left one real defect for the reviewer. Groups U and N are
built side by side, so the takeoffs carry their own unit bands, cluster grid,
scale statistic and room faces, and nothing ever retires them. Two readers of
one drawing can disagree. On Task 6's own inches-over-millimetres layout,
infer_units without room faces ties three ways and falls back to the header,
while the takeoff's bands say mm.
Task 11 gains Steps 15-20, committed on their own before the README figures
are retaken:
- describe.drawing_units becomes the one unit call, used by describe,
scale_check and the takeoffs;
- the takeoffs read plan copies, scale and rooms through group U's modules;
- the stand-ins are deleted;
- tests/test_understand_one_reading.py pins one unit, one plan copy, one
verdict and one set of rooms per drawing.
Tasks 3, 4 and 6 now point at those steps. Review Focus 1 names
parse_diameters, the function every task uses.
