Adds production-grade engineering features and tools: 2D GD&T (feature control frames + datum features) via engineering/gdt.py, ISO‑129 dimension tolerance support (engineering/tolerances.py) and an ezdxf/COM plumbing for toleranced dims, a scalar drawing score + invalidity ratio (engineering/scoring.py) wired into drawing_finalize, in-place entity editors (entity_edit_text/entity_edit_geometry), and a friendly drawing_settings facade. Includes server tool wiring, COM/ezdxf backend implementations, datum-consistency critique, many unit tests, README/CLAUDE/CHANGELOG updates, and a version bump to 1.2.0. Also corrects COM backend capability label (entities_2d).
New COM-only Entity Query tool that reads AutoCAD's implied ("pickfirst")
selection set and returns the selected entity handles + EntityInfo, so the AI
can scope work (e.g. dimension_auto) to exactly what the user picked in the
viewport instead of the whole drawing. Resolves#1 — the layer-juggling
workaround is no longer needed.
- backends/base.py: abstract selection_get() returning a status dict
- backends/com_backend.py: reads ActiveDocument.PickfirstSelectionSet, surfaces
the PICKFIRST sysvar, handles the empty-selection case
- backends/ezdxf_backend.py: headless stub (ok=False, empty handles, same shape)
- server.py: @mcp.tool registration (readOnlyHint), SECTION 5 3 -> 4 tools
- README + CHANGELOG + pyproject: 110 -> 111 tools, v1.1.0 -> v1.1.1
Verified live on AutoCAD 2027 (COM): selection_get correctly returned the
user's grip selection across two distinct picks; 318 tests pass, ruff-clean.

- benchmarks/correctness_suite.py: 21 deterministic headless (ezdxf) checks
across core ops, dimensions, arrays, geometry, query/parity, render, the
quality gate, and engineering.
- benchmarks/compare_versions.py: one-command A/B runner — checks out an older
ref into a throwaway worktree and runs the same suite against both, each check
in its own subprocess so a crash is a miss, not a run-killer.
- benchmarks/README.md: methodology, results table, honesty caveats.
- README: Benchmarks section now reports the measured result —
v1.0.0 8/21 (38.1%) -> v1.1.0 21/21 (100%); 13 fixed, 0 regressions.
- Delete .github/workflows/ci.yml and not.md.
- Drop the now-inaccurate "GitHub Actions CI" claims from README/CHANGELOG so
the v1.1.0 docs match reality (the ezdxf-in-your-CI capability notes remain).
