 ### Canvas-graph
 
+- [#209](https://github.com/2listic/dealiiX-platform/pull/209) The canvas now recognises the full set of CORAL node types. Non-void and `const` member functions (`method`, `const_method`) — previously unmapped and rendered as a broken generic node — now render and colour like the other methods. The coral-python `primitive` type is handled through the same unified node-type list.
+- [#209](https://github.com/2listic/dealiiX-platform/pull/209) Loading a graph no longer drops edges whose target input is typed `any`: import validation now accepts an `any` target input, matching the live connection validation used while drawing edges.
 - [#175](https://github.com/2listic/dealiiX-platform/issues/175) Per-level undo/redo history for the canvas. Each navigation level (root graph and each open subnetwork) keeps its own independent undo/redo stacks, capped at 50 entries. Undo (Ctrl/⌘+Z) and Redo (Ctrl/⌘+Shift+Z) are available as keyboard shortcuts and as items inside the Layout sidebar group button.

 - [#185](https://github.com/2listic/dealiiX-platform/pull/185) Parameter section duplicate logis is via a new duplicate button instead of via right-click. Duplicated sections can be deleted with a new delete button. Sections are set back to native `<details>`/`<summary>` elements for collapsible behaviour.
 - [#185](https://github.com/2listic/dealiiX-platform/pull/185) The execution modal now includes an editable parameters file name field, letting users override the file path per run without changing the global settings.
+- [#209](https://github.com/2listic/dealiiX-platform/pull/209) The local **Coral plugin path** setting is now a free-text field with a Browse button (previously a file picker only), so it accepts either a plugin file path or an arbitrary value passed to the backend's `-p` flag (e.g. a comma-separated list of modules). The local probe no longer requires the plugin path to be an existing file on disk.
+- [#209](https://github.com/2listic/dealiiX-platform/pull/209) Nodes with `node_type: "primitive"` now render an editable literal field (a text box, or a checkbox for booleans) like elementary constructors, so registries that use the `primitive` node type are fully usable on the canvas. Numeric value validation is also null-safe, so it no longer errors when a value is empty.
+- [#209](https://github.com/2listic/dealiiX-platform/pull/209) The **Download Graph** action moved from the Project group into the renamed **Import / Export** group, next to Import Graph. It no longer requires being logged in to a remote server, so the current graph can be exported to JSON while working locally.

+Defined in `src/lib/types/nodeTypes.ts`. A single `NodeType` enum covers every `node_type` string emitted by either backend (C++ coral and coral-python):
 
-- `ELEMENTARY_CONSTRUCTOR` - Primitive types (int, double, string)
+- `ELEMENTARY_CONSTRUCTOR` / `PRIMITIVE` - Literal-value leaf nodes holding a directly-entered value (int, double, string, bool). C++ coral emits `elementary_constructor`; coral-python emits `primitive`. Both render an editable literal input field.
 - `CONSTRUCTOR` / `EMPTY_CONSTRUCTOR` - Class constructors
 - `ABSTRACT` - Abstract base classes
-- `VOID_METHOD` / `VOID_CONST_METHOD` / `VOID_FUNCTION` / `FUNCTION` - Operations
+- `VOID_METHOD` / `VOID_CONST_METHOD` / `METHOD` / `CONST_METHOD` / `VOID_FUNCTION` / `FUNCTION` - Operations (member functions and free functions, void and non-void)
 - `NETWORK` - Encapsulated computational graphs (see Network Nodes below)
 
+`node_type` is only a rendering hint: it selects the canvas component (`FlowCanvas.svelte` `nodeTypes` map) and colour (`nodeColors` in `nodeTypes.ts`). Neither backend dispatches execution on it — nodes are identified by their `type` string. (coral-python's `primitive` vs C++ coral's `elementary_constructor` for the same literal-leaf concept is a known naming divergence; see `.ai/coral-python-integration/node-type-vocabulary-unification.md`.)

 Connection validation (`src/lib/utils/connectionsValidation.ts`) enforces type compatibility between node outputs and inputs.

 - **Canvas node creation**: `createCanvasNode(template, position, options?)` in `src/lib/utils/canvasNodeUtils.ts` creates a new @xyflow Node from a registry template. `getOutputTypeAndName(sourceNode, sourceHandle)` resolves the type/name for a source handle during drag-to-connect.

-- Configuration of a remote server with endpoint `/alive_remote` (FastAPI)
-- Configuration of a client application using Electron and SvelteFlow that will make SSH connections to a cluster and send data to the remote server

-The main objective of this initial end-to-end test is to test the client application, which should be able to:
-
-- Make SSH connections to different nodes in the cluster from the local machine.
-- Send data obtained from the cluster to a remote server.
