Umut CANandClaude Opus 5 02dbb133b5 feat(settings): live COM smoke on AutoCAD 2026 builds the five .dwt twins and records the run

scripts/smoke_settings_com.py --build-dwt exited 0 on AutoCAD 2026 (25.1s),
2026-09-22: five templates/*.dwt written through drawing_template_save
(SaveAs code 66, each file opens with AC1032), page setup plotted and the
PDF's own /MediaBox read back as 420.158 x 297.039 mm, iso_a3_mech.dwt
reopened as source "bundled" with ISO-25 current, layer state / named view /
UCS / preferences / SummaryInfo / prompt line all through the COM engine.
The record is in CHANGELOG.md under Unreleased. The smoke keeps a ledger of
the documents it opens and closes them on the way out, so a failed run never
leaves scratch documents on the operator's seat. Two of its expectations
were corrected to the merged tree: mleaderstyle_create is implemented on COM
(spec: no `mleaderstyle` key), and plot_style_list marks catalogue rows with
`installed`. --interactive was not run unattended on the shared seat (an
unanswered GetPoint holds the command line); Task 23 measured the pick live.
*.dwt / *.dwg are binary in .gitattributes; AutoCAD's plot.log is ignored.

Bundled drawing templates

Five templates, built by the server's own tools — never hand-edited — and listed by drawing_template_list. Start from one with drawing_new(template="iso_a3_mech").

name	standard	sheet	layer set	styles	page setup
`iso_a3_mech`	ISO	A3 landscape, ISO 5457 frame + ISO 7200 title block	mech	ISO-25 / ISOCP	ISO_A3, monochrome.ctb, 1:1
`iso_a1_arch`	ISO	A1 landscape	iso13567	ISO-25 / ISOCP, annotation scale 1:50	ISO_A1, monochrome.ctb, fit
`iso_a3_pid`	ISO	A3 landscape, ISO 5457 frame + title block	pid	ISO-25 / ISOCP	ISO_A3, monochrome.ctb, 1:1
`ansi_b_mech`	ANSI (metric)	ANSI B landscape	mech	ANSI / ROMANS	ANSI_B, monochrome.ctb, 1:1
`ansi_d_arch`	ANSI (metric)	ANSI D landscape	iso13567	ANSI / ROMANS	ANSI_D, monochrome.ctb, fit

The two files per template

<name>.dxf — the headless twin. Produced by uv run --frozen python scripts/build_templates.py, which runs drawing_new → apply_layer_set → styles → drawing_settings → layout rename → titleblock_apply_iso_a3 (A3 sheets) → page_setup_apply → drawing_save_as. scripts/build_templates.py --check rebuilds into a temporary folder and fails if any committed DXF differs (the save-time stamps $TDCREATE, $TDUPDATE, $FINGERPRINTGUID, $VERSIONGUID and the two EZDXF_META entries are masked; everything else must be byte-identical). tests/test_templates.py runs the same check.
<name>.dwt — the live twin, used by drawing_new(template=…) on the COM backend. AutoCAD's DWT is a DWG container, which no headless library writes, so these are produced on the live machine by uv run --frozen python scripts/smoke_settings_com.py --build-dwt (Task 25's smoke): it opens each DXF over COM and calls drawing_template_save(…dwt) (SaveAs(path, ac2018_Template)), then the files are committed once. While a .dwt is missing, resolve_template falls back to the DXF and reports source: "bundled_dxf"; drawing_template_list shows files.dwt.present. The live engine does not open that DXF blank: Documents.Add accepts only a genuine DWT (measured on AutoCAD 2026), so the COM drawing_new converts the DXF through SaveAs(…, ac2018_Template) once, caches the result under the temp folder keyed on path, size and mtime, and reports template_dwt: {path, cached}.

Line endings: ezdxf writes CRLF and .gitattributes pins templates/*.dxf to CRLF so a checkout on any platform equals a fresh build.

Rebuild after changing anything the build depends on (layer sets, the title block, the dimension presets, the settings facade) and commit the result together with the change — the reproducibility test is the gate.

The .dwt twins were built on 2026-09-22 on AutoCAD 2026 by scripts/smoke_settings_com.py --build-dwt — each DXF opened over COM and saved as a template (AcSaveAsType 66, ac2018_Template). Rebuild them the same way after changing a DXF; scripts/build_templates.py --check gates the DXF side only.
