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.

SolidOperation::Boolean runs synchronously, surfaces the kernel's refusal
with a plain reason and leaves the operands untouched, consumes them on
success unless keep_operands, and records one undo step. The lifecycle test
uses planar boxes with exact volumes and covers chaining, refusals, both
formats and undo; an ignored test shows a curved refusal reaching the script.

Times brep::combine in release against the pinned cadkernel: about 1-2 s for
curved operands, 1-2 ms for planar, versus 23 s in debug. Records the
kernel's frequent refusals, the host-thread and 30 s script-budget
implications, and recommends a synchronous Boolean operation that surfaces
refusals.

Adds SurfaceFromProfile and Extrude kernel operations (doc.solids.surface and
doc.solids.extrude), accepts surfaces in Transform, and maps Surface with
editable isolines. Fixes a real bug found by the test: the surface kind field
overwrote the entity-type kind key in Python dicts, so it is exposed as
surface_kind, with a catalog test guarding against name collisions.

RegionFromProfile reuses the REGION command's kernel calls; doc.solids.region
exposes it with layer and delete_source options. The lifecycle test builds
regions from real circle and polyline entities and covers refusals, a move,
both formats and undo. create_entity now accepts coordinate tuples for point
properties and every generated float setter accepts Python ints.

An additive HostApi::solid_operation builds cadkernel primitives and applies
rigid transforms, verifying each result lifts back losslessly and refusing a
payload it cannot lift. Exposed as doc.solids in Python; Solid3D, Body and
Region are mapped read-only with the opaque payload preserved. The lifecycle
test passes through the real runner with analytic volumes and exact extents as
oracles, DWG and DXF reopen with re-edit, and undo restores exactly.

OCS already creates, transforms and combines bodies through cadkernel, and
solid_to_sat / kernel_acis_body verify each result lifts back losslessly.
Two ignored spike tests measure volumes and DWG/DXF round trips. The
blocker is an operation channel, not geometry; the note recommends an
additive solid_operation host method and phases the work.
