Add an explicit close button to the right canvas toolbar, next to the undock control, and cover its label, handler, and ordering in the canvas regression test.
Treat document_artifact tool_args.method as an action alias so calls like method=create with format=xlsx create workbooks instead of falling back to LibreOffice status. Add regression coverage for the exact XLSX creation shape.
Remove the Collabora/WOPI runtime and route stack, including the old status APIs, proxy helpers, bootstrap extensions, and WOPI store tests. Add the Markdown-first document store, LibreOffice status/conversion helpers, LibreOfficeKit session bridge, and reusable Xpra virtual desktop gateway used by the new document runtime.
Update image and self-update bootstrap paths so existing containers can acquire the LibreOffice, XFCE, Xpra, and desktop-control dependencies through the normal install hooks instead of an ad hoc manual install.
Teach document_artifact to create embedded spreadsheet charts through a native create_chart operation, including generic line/bar/column/pie/area/scatter support and stock-style OHLC charts.
Parse CSV, TSV, and Markdown table content into real XLSX cells during spreadsheet creation so chart ranges bind to typed data instead of row text blobs.
Update the Office artifact skill and tool prompt to prefer native chart creation over Python fallback, and cover the workflow with regression tests.
Add read/edit support for Office document artifacts, including direct DOCX, XLSX, and PPTX updates with version history preservation. Inject compact active canvas metadata so agents can discover opened files without loading file contents. Move detailed usage guidance into the office-artifacts skill and keep the always-on tool prompt lean to avoid context bloat.
