Rewrite each entity's property builder to the per-entity group/row spec: the correct sections (Geometry, Misc, Text, Pattern, Lines & Arrows, Leaders, Block, …) with the spec's rows and real computed values — Diameter, Circumference, Area, Delta X/Y/Z, Angle, Total angle, Arc length, Radius ratio, etc. — plus apply routing for the editable rows. Covers ~26 entities (Line, Circle, Arc, Point, Ellipse, Spline, polylines, Ray/XLine, Insert, Text, MText, Hatch, Leader, MultiLeader, Tolerance, Solid, Solid3D/Region/Body, meshes, MLine, Raster/Wipeout, Underlay, Table, Viewport, Attribute, OLE). The 3D Visualization/Material group and the full Dimension spec are deferred (they need document access for material/dimstyle name resolution). Rows whose data is not in the pinned acadrust revision are shown as empty placeholders, to be filled when the dependency is bumped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
