+- **2026-10-11 (printing):** `file.printers` and `file.print` use craft-libs/craft-print for CUPS and Windows. DesignCraft retains PDF export, page selection, spreads, marks and bleed; dry runs create no temporary PDF or print job. Windows keeps sheet size/orientation and corrected duplex binding edges. Headless tests exercise exported bytes, job settings, dry runs and refusals; shared native Windows regression tests are present, with execution pending. PostScript, production print controls and physical output validation remain open. No readiness percentage change.
+
 - **2026-10-10 (UI.4–UI.5):** Panel tabs can move into other groups, split the dock, float, resize and return to their saved locations through shared docking transactions. Layouts persist in custom workspaces; UI and control commands share the same validated action path. Shared pane geometry and widget-state theme application retain all five palettes and local fonts. Split panes send keyboard input only to the focused canvas and scope contextual toolbar IDs per pane. No readiness percentage change.
 - **2026-10-10** · Version 0.6.0; releases add a Linux riscv64 tar.gz (cross-compiled, CLI
   smoke-tested under QEMU).
