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.

Unselected block text (the BS33-11 Mark/SectionMark labels) was erased by
its own block's wipeout pass and only came back through the selection
xray. Two compounding causes:
- Glyph quads rendered at the bare insert level, an exact depth tie with
every sibling fill, so the later wipeout pass won LessEqual. Wire
batches now carry the composed child rank as depth_override (the same
units the scene graph composes: depths[insert] + label * half), which
the block-text upload resolves per instance. Glyph vertices stay
neutral on purpose — baking the raw per-block label into them
double-counts and, for a negative rank, sinks the text BELOW its own
masks.
- The wipeout pipeline's depth bias (-8 quanta) was larger than the
whole within-block band: once child ranks compress into the insert's
half-band, sibling steps are ~3 quanta and a wipeout-to-text gap is
only 9-16 quanta of the 24-bit buffer. The mask only needs to break
exact ties, so the bias is now WIPEOUT_DEPTH_BIAS_QUANTA = 2.
block_text_draw_depth regression pins the contract: neutral vertices,
override carrying the rank, and a margin over the wipe that exceeds the
bias on a 600-entity scene.
