The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

OLE2FRAME entities whose compound file carries a metafile presentation
(Excel/Word previews, scanned WMF pages) drew only their border frame —
the old decoder scanned the raw blob for a contiguous BMP, which the
CFB sector layout almost never provides. acadrust now extracts the
picture bytes tagged by kind; the new scene/model/gdi player rasterizes
EMF and WMF record streams on the CPU (pens/brushes, polygons, paths,
DIB blits, clipping, transforms) with text drawn through the existing
system-font glyph cache, and image_model feeds the result into the
raster pipeline. Rasters (BMP/PNG/JPEG/GIF, CF_DIB) decode as before
via the image crate.
