The skeleton's header, constraints, file map and pinned interfaces now carry
their twelve tasks, in order:
- main (Tasks 1-2): the snapshot, vocabulary and label parsers, MAX_DXF_BYTES
512 MB and the office extra; the synthetic plant pair with its truth.
- U (Tasks 3-4): drawing_understand and drawing_scale_check; SECTION 26 opens.
- N (Tasks 5-8): the line network, orthogonal lengths and pipe rows, the
takeoff workbook with pipe_takeoff, then cable_takeoff; SECTION 27, pack plant.
- D (Tasks 9-10): drawing_diff and drawing_topology_check with the three
topo_* focuses, on D's own copy of SECTION 26.
- final (Tasks 11-12): packs, lean 65, aliases, golden queries and counts;
benchmark v7, five correctness checks, the live smoke, the field-test
script and the docs.
Interface pass: the U and N texts now say what Task 6 really does with the
scale check (it takes one through pipe_rows(scale=...) and otherwise keeps its
own stand-ins), and Task 11 moves D's block above SECTION 27 after the merge.
