Plugins can now declare the entity classes they identify via XDATA, and the
host resolves them to display-only type labels while the declaring plugin is
loaded.
- Append `BuiltinPlugin::entity_classes()` (a guarded trailing vtable slot,
the same additive pattern as `on_load` in v5) returning a &'static
`EntityClasses { app_id, class_prefix, labels }`. The static
`PluginManifest` struct is deliberately untouched: older cdylibs share it
by pointer and its layout is frozen ABI since v1, so adding a field would
read past their allocation.
- `OwnedEntityClasses` travels on the registered manifest as
`OwnedPluginManifest.entity_classes` with `#[serde(default)]`, so manifests
serialized before the field keep decoding (older runners tolerate it
both ways).
- The runner folds the declaration into the GetManifest registration only
when the loaded cdylib's exported `ocs_plugin_api_version` symbol reports
>= 10 — an older binary's vtable predates the slot, so it is never called;
its entities simply keep their native type names.
- `PluginManager::entity_class_declarations` exposes the live set, filtered
to alive, non-disabled plugins in load order. The registered manifests are
the only source and nothing is cached: not installed, disabled,
cap-excluded (`OCS_PLUGIN_MAX_API_VERSION`), failed at load, removed, or a
dead process all contribute nothing.
- Embedded version info `api_version` follows the bump to 10;
`API_VERSION_MIN_SUPPORTED` stays 3.
Tests: runner fold (v10 folds, pre-v10 skipped, `entity_classes()` panic is
contained and reported), manager filtering (disabled / dead / undeclaring
skipped; declarations disappear once the process dies — verified with a real
killed child), bincode registration round-trip, and older-manifest serde
default.
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.

Sync current main and companion codec changes before preserving unsupported frame rows, rendering in the entity plane, and sharing final layout metrics with placement preview.
