Files saved while a paper layout was active reopened in Model space because the loader hardcoded the current layout to "Model" and never consulted the space recorded in the file. The active space is a standard part of the format and acadrust already round-trips it: $TILEMODE (header.show_model_space) for model-vs-paper, and the CTAB current-tab variable for the exact layout name. - Read: on open, pick the current layout from CTAB (when it names a layout that exists), else $TILEMODE (Model, or the first paper layout). - Write: Scene::sync_active_space_to_document() mirrors the active layout back into the document (show_model_space + CTAB). It runs from set_current_layout, so every active-layout change — the status-bar tab, the Layout Manager's Set Current, create / rename / delete, and undo/redo — keeps the document in sync for the next save. $TILEMODE is the guaranteed mechanism (read and written for both DXF and DWG); CTAB refines the exact tab when the variable is present.
