#1688 accepted any degree (falling back to 3 on a malformed value) and
overwrote the degree the codec had clamped to the control-point count, so
a two-point default spline stored degree 3 against a degree-1 knot vector.
Reject a non-integer or out-of-range degree, too few control points for
the degree, a knot vector that is not control_points + degree + 1
non-decreasing values, and weights that are not one positive value per
control point.

Rebuild the Blocks palette with Current Drawing / Recent / Favorites /
Libraries tabs, wildcard filter, six views, insertion options, click and
drop insertion and a block context menu. INSERT opens the palette, the
new -INSERT runs on the command line, the ribbon Insert button becomes a
block gallery, and BLOCKMRULIST, BLOCKREDEFINEMODE, BLOCKNAVIGATE,
BLOCKSTATE, EXPLMODE and INSNAME are added.

Bug:
control_entities_transform validated the action field only inside the
transform closure - and invoked that closure from three of the match's
arms. Any other action fell into unreachable!("validated by
transform()") and aborted the process. The claim in the panic message
was false: for unknown actions the validating code never ran. The handler
is reachable from every remote surface (REST, MCP, --serve) because they
share this dispatch. Two extra triggers: "move " (trailing space, no
trim) and an all-whitespace action.
Reproduce:
1. Start OpenCADStudio with --http 8765.
2. POST /api/v1/entities (a LINE), take handles[0].
3. POST /api/v1/entities/transform with
{"handles":["<handle>"],"action":"explode"}.
4. Before: "internal error: entered unreachable code" and the process
exits.
5. After: {"ok":false,"code":"invalid_action",...} and the server keeps
serving. "action":"move " is now accepted (trimmed); " " is
rejected.
Fix:
The action is trimmed, lowercased and checked against the six-value
whitelist after require_existing (error precedence unchanged: a bad
handle still reports first) but before push_undo_snapshot, so an invalid
request no longer dirties the undo stack. The match's fallback arm
returns the same invalid_action error instead of unreachable!, so a
future mismatch between the whitelist and the match fails closed.
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.

The operations docs/automation/API-SPEC.md (PR #1383) describes, brought
over from huaninstratech/OpenCADStudio so the specification no longer runs
ahead of the code:
- entity CRUD: entities_create, entities_delete, entities_transform,
entities_copy_to, and `where` filters on query
- blocks and export: block_define, block_delete, a normalised wblock
- publishing: layout_create, page_setup_set, plot (per_page included)
- metadata: sysvar, xdata_set / xdata_get, file_identity
- collections: group_create, selection_set_save / load
- control plane: batch, events, view_focus, close
- the REST transport: `--http <port>`, the /api/v1 routes and their
OpenAPI 3 description
- person-in-the-loop picks: user_select and getpoint, hosted by the GUI
over the same REST routes, with on-screen pending signals
Taken from the fork's commits b7a7ed80, 69396b42, 64f1cf6a, c3aafc8e,
bb5a7bfa, 52317a5c, 50d293ba, b90e194f, 517c6397, 53a5c4c9, a49ac045,

fd5bc14d, 485fac61 and 2c5fc994.
Left out on purpose: 37de5a46 also removed the donation surface (the
Patreon fetch, the donation prompt, the Start-page supporters rail, the
DONATE command and its locale strings) and replaced the About dialog's call
to action; that is the fork's own product decision and stays out. The
fork's version bump and its unrelated IFC/BIM work are not part of this.
Adapted while porting: the REST server and the GUI bridge are desktop-only
and a template start is refused in the web build, so the wasm target still
compiles; the two plot tests read the PDF through the shared stream helper,
because exported streams are Flate-compressed; the benches set the new
crosshair field; comments and docs describe each operation in its own
terms rather than by another product's API names.
