-## What It Is
+## Overview
 
-Nodarium is a **node-based visual programming editor**. Users wire together nodes on a 2D canvas; each node is a WebAssembly module that receives typed inputs and produces typed outputs. A live Three.js viewer renders the resulting 3D geometry/paths/instances.
+Nodarium is a **WebAssembly-based visual programming language** for creating procedural 3D plants. The app features a node-based interface where users connect WASM modules to generate plant models in real-time. Currently used to develop https://nodes.max-richter.dev, a procedural modelling tool for 3D plants.

-### NodeInput socket types
+## Development Workflow
 
-`float` | `integer` | `boolean` | `select` | `seed` | `vec3` | `geometry` | `path` | `shape` | `color` | `*` (wildcard)
+### Prerequisites
 
-Each input can have: `value` (default), `label`, `hidden`, `external`, `setting` (link to graph setting), `accepts` (extra compatible types).
+- Node.js
+- pnpm
+- Rust
+- wasm-pack
 
----
-
-## Patterns & Conventions
-
-### Svelte 5 reactivity
-
-The codebase uses Svelte 5 runes throughout — `$state`, `$derived`, `$effect`. Collections use `SvelteMap<K,V>` and `SvelteSet<T>` (from `svelte/reactivity`) instead of plain Map/Set so that mutations trigger reactive updates.
-
-### Context API
-
-`GraphManager` and `GraphState` are provided via Svelte context (`setContext` / `getContext`) inside `GraphInterface`. All child components (Node, Edge, etc.) consume them via context rather than props.
-
-### Edge representation
-
-In memory, edges are `[NodeInstance, outputIndex, NodeInstance, inputSocketName]` — direct object references for fast traversal. On serialization (`Graph.edges`), they become `[nodeId, outputIndex, nodeId, inputSocketName]` (plain IDs).
-
-### Socket compatibility
-
-```typescript
-areSocketsCompatible(outputType: string, inputType: string | string[]): boolean
-// '*' wildcard matches any type; 'geometry' accepts ['geometry', 'instances']
-```
-
-### WASM execution interface
-
-Every node exposes a single function: `execute(input: Int32Array): Int32Array`.
-Data encoding (Plantarium):
-
-- `[0, stemDepth, ...x,y,z,thickness]` — path
-- `[1, vertexCount, faceCount, ...faces, ...vertices, ...normals]` — geometry
-- `[2, vertexCount, faceCount, instanceCount, stemDepth, ...]` — instances
-
-### Event emitter
-
-`GraphManager extends EventEmitter<{ save, result, settings }>`. Subscribe with `manager.on('result', cb)`. Used to decouple the editor UI from runtime execution and persistence.
-
-### History
-
-Every mutation goes through `HistoryManager`. Call `this.history.save(this.serialize())` before mutations; undo/redo replays jsondiffpatch deltas.
-
-### Internal node IDs
-
-Built-in nodes use the `__internal/` namespace: `__internal/group/instance`, `__internal/node/debug`. Virtual boundary nodes use `__virtual/`: `__virtual/group/input`, `__virtual/group/output`.
-
----
-
-## In-Progress: Node Groups (`feat/group-node-own`)
-
-Group selected nodes with **Ctrl+G**. A `GroupDefinition` is stored in `Graph.groups[]`; a group instance node (`__internal/group/instance`) referencing it by `props.groupId` replaces the selected nodes.

-| ----------------------------------------------------------------------------------------- | ------------------------------------------------------------------ |
-| `createGroupNode()` called but not defined                                                | `graph-state.svelte.ts:334` → missing in `graph-manager.svelte.ts` |
-| Runtime expects `group.graph.nodes/edges`; schema has flat `nodes/edges`                  | `runtime-executor.ts` vs `types.ts`                                |
-| Runtime expects `group.inputs` as array; schema defines it as `Record<string, NodeInput>` | Same mismatch                                                      |
-| `enterGroupNode()` is a stub — no group navigation                                        | `graph-state.svelte.ts`                                            |
-| `serialize()` writes parent-graph edges into group instead of group-internal edges        | `graph-manager.svelte.ts`                                          |
