A drawing somebody else made, read back as one report in which every
claim carries its evidence and a confidence; the drawing is never
modified.
- units.py: $INSUNITS against the unit the geometry implies (text
heights, wall thickness, door swings, labelled room areas, overall
size). The header is overruled only when the evidence outweighs it,
and then with a warning that quotes the numbers. Robust extents grow
from the quartile box of entity centres; what never joins is an
outlier, named by handle.
- clusters.py: separate bodies of model-space content by raster,
8-connectivity and box absorption - two copies of one plan are two
clusters.
- describe.py: layers with drawn length and the vocabulary's meaning
(name keyword, else the texts on the layer), equipment tags (one tag
lettered twice beside its symbol merged, repeats flagged ambiguous),
room labels in the wall-layer faces of engineering.arch.faces, text
languages by character class, blocks, layouts, the title block.
- server.py opens SECTION 26 (Understanding & QA) with
drawing_understand: core, read-only, tagged analysis/query. Alias
record, inventory, README release snapshot 242, frozen group sizes
(analysis 13).
