Summary

Docs only:

• CHANGELOG covers what landed on 2026-10-27 and 28:
  • the table objects (feat(objects): decode TABLESTYLE from R2010 and CELLSTYLEMAP (§20.4.101.2, §20.4.102, #151) #313, feat(objects): decode TABLEGEOMETRY from §20.4.103 (#151) #316, feat(objects): decode TABLECONTENT from §20.4.97 (#151) #317, feat(entities): decode ACAD_TABLE from §20.4.96 (#151) #319);
  • the nineteen classes derived from AutoCAD's own output (feat(objects): decode five small classes from AutoCAD's own DWG and DXF output (#152) #326 to feat(objects): decode ACSH_EXTRUSION_CLASS from AutoCAD's own DWG and DXF output (#152) #341), with the DATATABLE allocation bound;
  • the DIMENSION scorer (feat(dxf): score the DIMENSION family in the value oracle (§20.4.22 to §20.4.29) #387);
  • the BLOCK fixtures (test(fixtures): emit BLOCK_HEADER and BLOCK pairs so the name gate runs in CI (#78) #407, closes build_fixtures: emit a BLOCK_HEADER + BLOCK pair so the #70 name-join gate runs in CI, not only on the local corpus #78);
  • jev_review.py and the AutoCAD trial tooling (feat(tools): rank the prose and open issues that merged pull requests may have overtaken #406, feat(tools): scripts and runbook for the AutoCAD trial (#119, #348, #375) #383);
  • the merge train's stack handling (fix(ci): settle a Codex thread that asks to commit the measured corpus baseline #421, fix(ci): merge a stacked PR against the newest commit it holds of the landed PR below it #422, fix(ci): hold a stacked PR until the older PR it builds on lands #423).
• README said every skipped type had a decoder in review. Only SHAPE (feat(entities): decode SHAPE from §20.4.37 (#140) #310) and the VIEWPORT entity header (feat(objects): decode VIEWPORT ENTITY HEADER from §20.4.70 (#146) #311) do. The other twelve skipped types are custom classes in the four BookViewerApp3 drawings, which have no DXF export yet; they are now named, and listed under what the crate does not do.
• STATUS.md's pending section says its counts are the 2026-08-30 snapshot.

Evidence

• Skipped and decoded totals come from the committed tools/corpus/baseline.tsv at each landing: 379 skipped before feat(objects): decode TABLESTYLE from R2010 and CELLSTYLEMAP (§20.4.101.2, §20.4.102, #151) #313, 44 after feat(objects): decode ACSH_EXTRUSION_CLASS from AutoCAD's own DWG and DXF output (#152) #341, 0 errored throughout.
• The remaining types come from the corpus-measurement artifact of CI run 40655020787 (feat(objects): decode ACSH_EXTRUSION_CLASS from AutoCAD's own DWG and DXF output (#152) #341's head).
• readme_status.py --check passes.
• jev_review.py prose was run on the edited documents. It caught an overbroad "ACDBASSOC*" in the first draft (feat(objects): decode ACDBASSOCPERSSUBENTMANAGER and ACDBPERSSUBENTMANAGER from AutoCAD's own DWG and DXF output (#152) #379 decodes ACDBASSOCPERSSUBENTMANAGER); the classes are now named one by one.

Source-provenance declaration

By submitting this PR I certify that my contribution does not incorporate executable code from any source whose license is incompatible with Apache-2.0. Specifically:

• No Autodesk DWG SDK source (RealDWG, ObjectARX, ObjectDBX) or NDA-protected Autodesk documentation was consulted or imported.
• No Open Design Alliance Teigha / Drawings SDK source was consulted or imported. The ODA's public Open Design Specification for .dwg files PDF is explicitly allowed (see CLEANROOM.md).
• No GPL-licensed DWG implementation source (LibreDWG, etc.) was consulted or imported. This matters because dwg-rs is Apache-2.0 and must remain compatible.

My contribution is based on:

• The ODA's freely-redistributable Open Design Specification for .dwg files (v5.4.1);
• Public reverse-engineering notes, research papers, or blog posts cited inline;
• Reading algorithm-description comments (not executable code) in permissively-licensed projects (MIT / Apache / BSD) to resolve spec ambiguities — disclose any such reading in this PR body so it can be recorded in CLEANROOM.md.

See CLEANROOM.md for the full allowed/forbidden source list and the honest scope of what "clean-room" means for this project.

Developer Certificate of Origin

By submitting this PR, I certify that the contribution complies with the
Developer Certificate of Origin 1.1.
Specifically, I affirm that the contribution is my own work (or rightfully
licensed to me) and that it can be distributed under the project's Apache-2.0
license.

I will sign off commits with git commit -s when asked, which adds a
Signed-off-by trailer to the commit message asserting the DCO.
