engineering/mech/ opens with the four modules every track-B/G branch imports, so the four worktrees can be cut from this commit and none of them has to invent a name the others will conflict with. - primitives.py: the typed descriptions the pure modules emit (Line, Arc, Circle, Poly, HatchArea, Text, DimIntent) with bbox / translate / rotate / scale, and ROLE_LAYER - the one place an ISO 128 line role becomes a layer name, so no module hardcodes a layer. The arc bbox sweeps its quadrants: a 0-180 arc reports y=+r, not its endpoints, which is what keeps the view layout from stacking two views on top of each other. - xdata.py: the ACADMCP_MECH codec in Track A's shape - a 1001 application marker, 1000 chunks of at most 255 ASCII characters, the 16 KB per-entity ceiling enforced before anything is written, and a foreign application, a corrupt chunk stream, a wrong version or an unknown kind refused with ValueError instead of decoded into something plausible. - standards/__init__.py: the table registry. A size outside the coverage is refused against the coverage; a size inside it that is not a listed row is refused against the rows. Nothing is interpolated, an ambiguous variant is never resolved by taking the first row, and a registration whose SOURCE does not name the table it was transcribed from is refused. - standards/materials.py: the section-hatch map for nine materials. ISO 128-50 standardises only the general hatching (narrow continuous lines at 45 degrees) - that is acadiso.pat ANSI31 and what engineering/gear.py already draws for steel. The distinguishing symbols are ASME Y14.2M's section lining as shipped in AutoCAD 2026's acadiso.pat, read off the installed file; cast iron's departure from ASME and the absence of any mechanical symbol for concrete and wood are stated in the rows themselves. Angles are 0.0 because the patterns already carry 45 degrees, and the two architectural patterns' scales are derived from the ANSI31 line spacing and recomputed by the test rather than chosen. No tool is registered here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FKFStjEFzpGyLq5bMpWxTd
