Codec: PRs #71-#74 merged (MPOLYGON layout, multiline ATTDEF/ATTRIB DXF, DXF MATERIAL/ACSH matrix, restorable SAT/SAB + history roots) and issues #55 #64-#69 fixed. EntityType now boxes Surface, Extended, Table, MultiLeader and Helix (2344 B -> 848 B per entity): construction sites wrap in Box, the entity traits forward through Box, and the python plugin generator converts with into(). Kernel: PR #70 (cuboid ring winding). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
