+
+## Motivation
+
+Moving Rhizome to Elixir and the BEAM virtual machine provides several key advantages:
+
+1. **Distribution by Default**
+   - Built-in distribution primitives for node-to-node communication
+   - Network partition tolerance out of the box
+   - Location transparency for processes
+
+2. **Fault Tolerance**
+   - Let it crash philosophy with supervision trees
+   - Self-healing systems through process isolation
+   - Hot code reloading for zero-downtime updates
+
+3. **Concurrency Model**
+   - Lightweight processes for handling millions of concurrent connections
+   - Efficient message passing between processes
+   - Built-in backpressure handling
+
+4. **Ecosystem Benefits**
+   - Mature tooling for distributed systems
+   - Strong pattern matching and immutability
+   - Excellent support for building resilient systems

+## Key Components
+
+### 1. Delta Processing
+This implementation will follow similar patterns to the TypeScript version but leverage Elixir's strengths:
+```elixir
+defmodule Rhizome.Delta do
+  @type t :: %__MODULE__{
+    id: String.t(),
+    creator: String.t(),
+    timestamp: integer(),
+    operations: [operation()],
+    transaction_id: String.t() | nil,
+    negate: boolean()
+  }
+  
+  defstruct [:id, :creator, :timestamp, :operations, :transaction_id, negate: false]
+  
+  def new(creator, host) do
+    %__MODULE__{
+      id: generate_id(),
+      creator: creator,
+      timestamp: System.system_time(:millisecond),
+      operations: []
+    }
+  end
+  
+  def add_operation(delta, operation) do
+    %{delta | operations: [operation | delta.operations]}
+  end
+end
+```
+
+### 2. View System
+```elixir
+defmodule Rhizome.View.Lossy do
+  @behaviour Rhizome.View.Behaviour
+  
+  @impl true
+  def init(initial_state) do
+    %{state: initial_state, cache: %{}}
+  end
+  
+  @impl true
+  def reduce(%{state: state} = view, delta) do
+    new_state = apply_delta(state, delta)
+    %{view | state: new_state}
+  end
+  
+  @impl true
+  def resolve(%{state: state}), do: state
+  
+  defp apply_delta(state, %Delta{operations: ops}) do
+    Enum.reduce(ops, state, &apply_operation/2)
+  end
+end
+```
+
+### 3. Plugin System
+```elixir
+defmodule Rhizome.Plugin do
+  @callback init(args :: term) :: {:ok, state :: term} | {:error, reason :: term}
+  @callback handle_delta(delta :: Delta.t(), state :: term) :: {:ok, new_state :: term} | {:error, term}
+  @callback handle_call(request :: term, from :: {pid, reference}, state :: term) ::
+    {:reply, reply, new_state} |
+    {:reply, reply, new_state, timeout | :hibernate} |
+    {:noreply, new_state} |
+    {:noreply, new_state, timeout | :hibernate} |
+    {:stop, reason, reply, new_state} |
+    {:stop, reason, new_state} when reply: term, new_state: term, reason: term
+  
+  defmacro __using__(_opts) do
+    quote do
+      @behaviour Rhizome.Plugin
+      use GenServer
+      
+      # Default implementations
+      @impl true
+      def init(_args), do: {:ok, %{}}
+      
+      @impl true
+      def handle_call(_request, _from, state), do: {:reply, :ok, state}
+      
+      def start_link(args) do
+        GenServer.start_link(__MODULE__, args, name: __MODULE__)
+      end
+    end
+  end
+end
+```
+
+## Data Synchronization Model
+
+### 1. Delta Propagation
+```mermaid
+sequenceDiagram
+    participant C1 as Client 1
+    participant N1 as Node 1
+    participant N2 as Node 2
+    participant N3 as Node 3
+    
+    C1->>N1: Submit Delta
+    N1->>N1: Apply Delta Locally
+    N1->>N2: Gossip Delta
+    N1->>N3: Gossip Delta
+    N2->>N2: Apply Delta
+    N3->>N3: Apply Delta
+    N2->>N1: Acknowledge
+    N3->>N1: Acknowledge
+```
+
+### 2. Conflict Resolution
+1. **Last Write Wins** (Default)
+2. **Custom Resolvers**
+3. **CRDT-based** for special cases

+# Dimensions
+
+Deltas are a hyperstructure capable of expressing many structures.
+
+We can consider models which we compose by expressing their dimensions, and
+relationships between those dimensions. This can enable a robust form of multi-dimensional
+composition. I'm thinking in terms of vectors and matrices, maybe quaternions, tensors.
+
+So basically we can use deltas to encode math.

+# Entity Relationship Graph
+
+## Background
+
+Deltas can express relationships by declaring a domain entity for the relationship itself.
+
+Our initial implementation assumes there is only one structure for a relationship: a directed edge from one entity to another.
+- `source` and `target` are required properties.
+- `type` as well as arbitrary additional properties are optional.
+
+Future work may allow for more complex relationships.
+
+## Goal
+
+Resolve a graph of relationships among entities.

+- before test, initialize node and lossless view
+- when test begins, create and ingest a series of deltas
+- instantiate a resolver, in this case using custom resolver plugins
+- call the resolver's initializer with the view
+- call the resolver's reducer with the view
+- call the resolver's resolver with the view

+# Follow-up
+- why isn't the resolver being called automatically, by event dispatch?
+- we can prepare an array of deltas and pass it to a test helper,
+- So our entire test case should consist of the deltas, the resolver, and the expected result.

+## Key Components
+
+1. **RhizomeNode**: The main entry point that coordinates all other components
+   - Manages the node's lifecycle and configuration
+   - Coordinates between different subsystems
+
+2. **Delta**: The fundamental data unit
+   - Represents atomic changes in the system
+   - Contains pointers to entities and their properties
+
+3. **Lossless**: Manages the lossless view of data
+   - Maintains the complete history of deltas
+   - Provides methods to view and compose entity states
+
+4. **QueryEngine**: Handles data queries
+   - Supports filtering with JSON Logic
+   - Works with the schema system for validation
+
+5. **StorageQueryEngine**: Handles storage-level queries
+   - Interfaces with the underlying storage backend
+   - Optimized for querying persisted data
+
+6. **SchemaRegistry**: Manages data schemas
+   - Validates data against schemas
+   - Supports schema versioning and evolution
+
+7. **DockerOrchestrator**: Manages containerized nodes
+   - Handles node lifecycle (start/stop)
+   - Manages networking between nodes
+
+## Data Flow
+
+1. Deltas are received through the DeltaStream
+2. Lossless processes and stores these deltas
+3. Queries can be made through either QueryEngine (in-memory) or StorageQueryEngine (persisted)
+4. The system maintains consistency through the schema system
+5. In distributed mode, DockerOrchestrator manages multiple node instances

+# CustomResolver Class
+
+## Overview
+
+The `CustomResolver` class is the main entry point for the Custom Resolver system. It manages the resolution of entity properties using the configured plugins and handles dependency resolution between them.
+
+## Class Definition
+
+```typescript
+class CustomResolver {
+  /**
+   * Creates a new CustomResolver instance
+   * @param view The lossless view to resolve
+   * @param config Plugin configuration
+   */
+  constructor(
+    private readonly view: LosslessView,
+    private readonly config: ResolverConfig
+  );
+
+  /**
+   * Processes all entities in the view and returns the resolved values
+   */
+  resolve(): CustomResolverResult;
+
+  /**
+   * Processes a single entity and returns its resolved values
+   * @param entityId ID of the entity to resolve
+   */
+  resolveEntity(entityId: string): EntityResult | undefined;
+
+  /**
+   * Gets the current processing order of properties
+   */
+  getProcessingOrder(): string[];
+
+  /**
+   * Gets the dependency graph
+   */
+  getDependencyGraph(): Map<string, Set<string>>;
+}
+```
+
+## Constructor
+
+### `new CustomResolver(view, config)`
+
+Creates a new instance of the CustomResolver.
+
+**Parameters:**
+- `view: LosslessView` - The lossless view containing the data to resolve
+- `config: ResolverConfig` - Configuration object mapping property IDs to their resolver plugins
+
+**Example:**
+```typescript
+const resolver = new CustomResolver(view, {
+  price: new LastWriteWinsPlugin(),
+  discount: new LastWriteWinsPlugin(),
+  total: new TotalPricePlugin()
+});
+```
+
+## Methods
+
+### `resolve(): CustomResolverResult`
+
+Processes all entities in the view and returns the resolved values.
+
+**Returns:** `CustomResolverResult` - Object mapping entity IDs to their resolved properties
+
+**Example:**
+```typescript
+const results = resolver.resolve();
+debug(results);
+// {
+//   'entity1': {
+//     id: 'entity1',
+//     properties: { price: 100, discount: 10, total: 90 }
+//   },
+//   // ...
+// }
+```
+
+### `resolveEntity(entityId: string): EntityResult | undefined`
+
+Processes a single entity and returns its resolved values.
+
+**Parameters:**
+- `entityId: string` - ID of the entity to resolve
+
+**Returns:** `EntityResult | undefined` - Resolved entity or undefined if not found
+
+**Example:**
+```typescript
+const result = resolver.resolveEntity('order-123');
+if (result) {
+  debug(`Order total: ${result.properties.total}`);
+}
+```
+
+### `getProcessingOrder(): string[]`
+
+Gets the current processing order of properties based on their dependencies.
+
+**Returns:** `string[]` - Array of property IDs in processing order
+
+**Example:**
+```typescript
+const order = resolver.getProcessingOrder();
+debug('Processing order:', order);
+// ['price', 'discount', 'total']
+```
+
+### `getDependencyGraph(): Map<string, Set<string>>`
+
+Gets the dependency graph used for resolution.
+
+**Returns:** `Map<string, Set<string>>` - Map where keys are property IDs and values are sets of their dependencies
+
+**Example:**
+```typescript
+const graph = resolver.getDependencyGraph();
+for (const [prop, deps] of graph.entries()) {
+  debug(`${prop} depends on:`, [...deps]);
+}
+```
+
+## Configuration
+
+The resolver is configured with an object mapping property IDs to their resolver plugins:
+
+```typescript
+interface ResolverConfig {
+  [propertyId: string]: ResolverPlugin<any, string>;
+}
+```
+
+## Error Handling
+
+The resolver may throw the following errors:
+
+- `Error` - For invalid configurations or dependency cycles
+- `TypeError` - For type mismatches or invalid plugin implementations
+
+## Example: Complete Usage
+
+```typescript
+import { CustomResolver, LastWriteWinsPlugin } from './resolver';
+import { LosslessView } from '../lossless-view';
+
+// Create a lossless view with some data
+const view = new LosslessView();
+// ... add data to the view ...
+
+// Configure the resolver
+const resolver = new CustomResolver(view, {
+  // Simple plugins
+  productId: new LastWriteWinsPlugin(),
+  quantity: new LastWriteWinsPlugin(),
+  
+  // Plugin with dependencies
+  unitPrice: new LastWriteWinsPlugin(),
+  discount: new LastWriteWinsPlugin(),
+  taxRate: new LastWriteWinsPlugin(),
+  
+  // Complex plugin with multiple dependencies
+  subtotal: new class extends ResolverPlugin<SubtotalState, 'unitPrice' | 'quantity'> {
+    readonly dependencies = ['unitPrice', 'quantity'] as const;
+    
+    initialize() { return { value: 0 }; }
+    
+    update(_state, _value, _delta, deps) {
+      const unitPrice = deps.unitPrice as number;
+      const quantity = deps.quantity as number;
+      return { value: unitPrice * quantity };
+    }
+    
+    resolve(state) { return state.value; }
+  }(),
+  
+  // More plugins...
+});
+
+// Resolve all entities
+const results = resolver.resolve();
+debug(results);
+
+// Or resolve a single entity
+const order = resolver.resolveEntity('order-123');
+debug(order);
+```
+
+## Best Practices
+
+1. **Reuse Instances**: Create a single resolver instance and reuse it
+2. **Minimize Dependencies**: Keep the dependency graph simple and acyclic
+3. **Error Handling**: Always handle potential errors in plugin implementations
+4. **Performance**: Be mindful of plugin complexity in hot code paths

+# ResolverPlugin Interface
+
+## Overview
+
+The `ResolverPlugin` interface defines the contract that all resolver plugins must implement. It provides type-safe access to plugin state and dependencies.
+
+## Interface Definition
+
+```typescript
+interface ResolverPlugin<T = unknown, D extends string = never> {
+  /**
+   * Unique identifier for the plugin
+   */
+  readonly name: string;
+
+  /**
+   * Array of property IDs this plugin depends on
+   * @default []
+   */
+  readonly dependencies?: readonly D[];
+
+  /**
+   * Initializes the plugin's state
+   * @returns Initial state object
+   */
+  initialize(): T;
+
+  /**
+   * Processes a new value and updates the plugin's state
+   * @param currentState Current plugin state
+   * @param newValue New value to process
+   * @param delta Delta information
+   * @param dependencies Resolved states of all declared dependencies
+   * @returns Updated plugin state
+   */
+  update(
+    currentState: T,
+    newValue: PropertyTypes,
+    delta: CollapsedDelta,
+    dependencies: DependencyStates
+  ): T;
+
+  /**
+   * Resolves the final value from the current state
+   * @param state Current plugin state
+   * @param dependencies Resolved states of all declared dependencies
+   * @returns Resolved value or undefined if no value should be set
+   */
+  resolve(
+    state: T,
+    dependencies: DependencyStates
+  ): PropertyTypes | undefined;
+}
+```
+
+## Type Parameters
+
+| Parameter | Description |
+|-----------|-------------|
+| `T` | Type of the plugin's internal state |
+| `D` | Union type of dependency names (must extend `string`) |
+
+## Methods
+
+### `initialize()`
+
+Initializes the plugin's internal state. Called once when the resolver is created.
+
+**Returns:** `T` - The initial state object
+
+### `update(currentState, newValue, delta, dependencies)`
+
+Processes a new value and updates the plugin's state.
+
+**Parameters:**
+- `currentState: T` - Current plugin state
+- `newValue: PropertyTypes` - New value to process
+- `delta: CollapsedDelta` - Delta information
+- `dependencies: DependencyStates` - Resolved states of all declared dependencies
+
+**Returns:** `T` - Updated plugin state
+
+### `resolve(state, dependencies)`
+
+Resolves the final value from the current state.
+
+**Parameters:**
+- `state: T` - Current plugin state
+- `dependencies: DependencyStates` - Resolved states of all declared dependencies
+
+**Returns:** `PropertyTypes | undefined` - Resolved value or undefined if no value should be set
+
+## Example Implementation
+
+```typescript
+class CounterPlugin extends ResolverPlugin<CounterState> {
+  
+  initialize(): CounterState {
+    return { count: 0 };
+  }
+  
+  update(
+    state: CounterState,
+    _newValue: unknown,
+    _delta: CollapsedDelta,
+    _deps: {}
+  ): CounterState {
+    return { count: state.count + 1 };
+  }
+  
+  resolve(state: CounterState): number {
+    return state.count;
+  }
+}
+```
+
+## Best Practices
+
+1. **Immutability**: Always return new state objects instead of mutating
+2. **Purity**: Keep methods pure and side-effect free
+3. **Error Handling**: Handle unexpected input gracefully
+4. **Documentation**: Document expected types and behavior
+
+## Common Patterns
+
+### Accessing Dependencies
+
+```typescript
+class PriceCalculator extends ResolverPlugin<PriceState, 'basePrice' | 'taxRate'> {
+  readonly dependencies = ['basePrice', 'taxRate'] as const;
+  
+  update(
+    _state: PriceState,
+    _newValue: unknown,
+    _delta: CollapsedDelta,
+    deps: DependencyStates,
+  ): PriceState {
+    const basePrice = deps.basePrice as number;
+    const taxRate = deps.taxRate as number;
+    return { total: basePrice * (1 + taxRate) };
+  }
+  
+  // ...
+}
+```
+
+### Optional Dependencies
+
+```typescript
+class OptionalDepPlugin extends ResolverPlugin<State, 'required' | 'optional?'> {
+  readonly dependencies = ['required', 'optional?'] as const;
+  
+  update(
+    state: State,
+    _newValue: unknown,
+    _delta: CollapsedDelta,
+    deps: any,
+  ): State {
+    const required = deps.required as number; // Always present
+    const optional = deps['optional?'] as number | undefined; // Might be undefined
+    
+    // ...
+  }
+  
+  // ...
+}
+```

+# Common Types and Interfaces
+
+This document describes the common types and interfaces used throughout the Custom Resolver system.
+
+## Core Types
+
+### `PropertyID`
+
+```typescript
+type PropertyID = string;
+```
+
+Unique identifier for a property.
+
+### `PropertyTypes`
+
+```typescript
+type PropertyTypes = 
+  | string 
+  | number 
+  | boolean 
+  | null 
+  | undefined 
+  | PropertyTypes[] 
+  | { [key: string]: PropertyTypes };
+```
+
+All possible property value types that can be handled by the resolver.
+
+### `DependencyStates`
+
+```typescript
+type DependencyStates = {
+  [K in D]: unknown;
+};
+```
+
+Maps dependency names to their resolved values. The actual type of each value depends on the plugin that produced it.
+
+### `CollapsedDelta`
+
+```typescript
+interface CollapsedDelta {
+  timestamp: number;
+  source?: string;
+  // ... other delta metadata
+}
+```
+
+Represents a collapsed delta with metadata about the change.
+
+## Plugin Types
+
+### `ResolverPlugin<T, D>`
+
+```typescript
+interface ResolverPlugin<T = unknown, D extends string = never> {
+  readonly name: string;
+  readonly dependencies?: readonly D[];
+  
+  initialize(): T;
+  update(
+    currentState: T,
+    newValue: PropertyTypes,
+    delta: CollapsedDelta,
+    dependencies: DependencyStates
+  ): T;
+  
+  resolve(
+    state: T,
+    dependencies: DependencyStates
+  ): PropertyTypes | undefined;
+}
+```
+
+The main plugin interface. See [ResolverPlugin Interface](./resolver-plugin-interface.md) for details.
+
+## Result Types
+
+### `EntityResult`
+
+```typescript
+interface EntityResult {
+  id: string;
+  properties: {
+    [propertyId: string]: PropertyTypes;
+  };
+}
+```
+
+A basic map of some results. May represent entites, entity properties, or arbitrary synthetic attributes.
+
+### `CustomResolverResult`
+
+```typescript
+interface CustomResolverResult {
+  [entityId: string]: EntityResult;
+}
+```
+
+Maps entity IDs to their resolved properties.
+
+## Configuration Types
+
+### `ResolverConfig`
+
+```typescript
+interface ResolverConfig {
+  [propertyId: string]: ResolverPlugin<any, string>;
+}
+```
+
+Configuration object mapping property IDs to their resolver plugins.
+
+## Built-in Plugin Types
+
+### `LastWriteWinsPlugin`
+
+```typescript
+class LastWriteWinsPlugin extends ResolverPlugin<LastWriteWinsState> {
+  // ...
+}
+
+interface LastWriteWinsState {
+  value?: PropertyTypes;
+  timestamp: number;
+}
+```
+
+### `FirstWriteWinsPlugin`
+
+```typescript
+class FirstWriteWinsPlugin extends ResolverPlugin<FirstWriteWinsState> {
+  // ...
+}
+
+interface FirstWriteWinsState {
+  value?: PropertyTypes;
+  isSet: boolean;
+}
+```
+
+### `ConcatenationPlugin`
+
+```typescript
+interface ConcatenationOptions {
+  separator?: string;
+  sort?: boolean;
+}
+
+class ConcatenationPlugin extends ResolverPlugin<ConcatenationState> {
+  
+  constructor(private options: ConcatenationOptions = {}) {
+    this.options = {
+      separator: options.separator || ', ',
+      sort: options.sort || false
+    };
+  }
+  // ...
+}
+
+interface ConcatenationState {
+  values: Set<string>;
+  separator: string;
+  sort: boolean;
+}
+```
+
+### `MajorityVotePlugin`
+
+```typescript
+interface MajorityVoteOptions {
+  minVotes?: number;
+}
+
+class MajorityVotePlugin extends ResolverPlugin<MajorityVoteState> {
+  
+  constructor(private options: MajorityVoteOptions = {}) {
+    this.options = {
+      minVotes: options.minVotes || 1
+    };
+  }
+  // ...
+}
+
+interface MajorityVoteState {
+  votes: Map<string, number>;
+  minVotes: number;
+}
+```
+
+## Type Utilities
+
+### `DependencyKeys<T>`
+
+Extracts the dependency keys from a plugin type.
+
+```typescript
+type DependencyKeys<T> = 
+  T extends ResolverPlugin<any, infer D> ? D : never;
+```
+
+### `PluginState<T>`
+
+Extracts the state type from a plugin type.
+
+```typescript
+type PluginState<T> = 
+  T extends ResolverPlugin<infer S, any> ? S : never;
+```
+
+## Example: Working with Types
+
+### Type-Safe Plugin Implementation
+
+```typescript
+// Define state and dependency types
+interface CounterState {
+  count: number;
+}
+
+type CounterDeps = 'incrementBy' | 'resetThreshold';
+
+// Implement plugin with type safety
+class CounterPlugin extends ResolverPlugin<CounterState, CounterDeps> {
+  readonly dependencies = ['incrementBy', 'resetThreshold'] as const;
+  
+  initialize(): CounterState {
+    return { count: 0 };
+  }
+  
+  update(
+    state: CounterState,
+    _newValue: unknown,
+    _delta: CollapsedDelta,
+    deps: DependencyStates
+  ): CounterState {
+    const increment = deps.incrementBy as number;
+    const threshold = deps.resetThreshold as number;
+    
+    const newCount = state.count + increment;
+    return {
+      count: newCount >= threshold ? 0 : newCount
+    };
+  }
+  
+  resolve(state: CounterState): number {
+    return state.count;
+  }
+}
+```
+
+## Type Assertions
+
+When working with dependency values, you'll often need to use type assertions since they're typed as `unknown`:
+
+```typescript
+// Type assertion
+const value = deps.someDependency as SomeType;
+
+// Type guard
+if (typeof deps.someDependency === 'number') {
+  // deps.someDependency is now typed as number
+}
+```
+
+## Best Practices
+
+1. **Use `as const`** for string literals to get the most specific type
+2. **Narrow types** when accessing dependency values
+3. **Document expected types** in JSDoc comments
+4. **Handle undefined** values when dependencies might be missing
+5. **Use type guards** for runtime type safety when needed

+# Dependency Resolution
+
+## Overview
+
+The Custom Resolver system includes a robust dependency resolution mechanism that ensures plugins are processed in the correct order based on their dependencies. This document explains how the resolution process works and how to work with complex dependency graphs.
+
+## How Dependency Resolution Works
+
+1. **Graph Construction**: The system builds a directed graph of plugin dependencies during initialization.
+2. **Cycle Detection**: The graph is checked for cycles to prevent infinite loops.
+3. **Topological Sort**: Plugins are ordered such that all dependencies are processed before the plugins that depend on them.
+4. **State Resolution**: During processing, each plugin receives the resolved states of its dependencies.
+
+## Example: Resolving Dependencies
+
+Consider the following plugin configuration:
+
+```typescript
+const resolver = new CustomResolver(view, {
+  basePrice: new LastWriteWinsPlugin(),
+  discount: new LastWriteWinsPlugin(),
+  taxRate: new LastWriteWinsPlugin(),
+  tax: new TaxCalculatorPlugin(),      // Depends on basePrice and taxRate
+  total: new TotalPricePlugin()        // Depends on basePrice, discount, and tax
+});
+```
+
+The system will automatically determine the correct processing order:
+
+1. `basePrice`, `discount`, `taxRate` (no dependencies)
+2. `tax` (depends on basePrice and taxRate)
+3. `total` (depends on basePrice, discount, and tax)
+
+## Handling Circular Dependencies
+
+Circular dependencies are detected during initialization and will result in an error. For example:
+
+```typescript
+// This will throw an error during initialization
+const resolver = new CustomResolver(view, {
+  a: new SomePlugin({ deps: ['b'] }),
+  b: new SomePlugin({ deps: ['a'] })  // Circular dependency!
+});
+```
+
+## Advanced Dependency Patterns
+
+### Optional Dependencies
+
+To make a dependency optional, mark it with a `?` suffix:
+
+```typescript
+class MyPlugin extends ResolverPlugin<MyState, 'required' | 'optional?'> {
+  readonly dependencies = ['required', 'optional?'] as const;
+  
+  // ...
+}
+```
+
+### Dynamic Dependencies
+
+For plugins that need to determine dependencies at runtime, you can implement a custom resolver:
+
+```typescript
+class DynamicDepsPlugin extends ResolverPlugin<DynamicState> {
+  
+  getDependencies(config: any): string[] {
+    // Determine dependencies based on config
+    return ['always'];
+  }
+  
+  // ...
+}
+```
+
+## Debugging Dependency Issues
+
+### Common Issues
+
+1. **Missing Dependencies**: Ensure all required dependencies are declared
+2. **Type Mismatches**: Verify that dependency types match expected types
+3. **Circular Dependencies**: Break circular references in your dependency graph
+
+### Debugging Tools
+
+1. **Dependency Graph**: Use `resolver.getDependencyGraph()` to inspect the dependency graph
+2. **Processing Order**: Check `resolver.getProcessingOrder()` to see the resolved execution order
+3. **Logging**: Enable debug logging to track dependency resolution
+
+## Performance Considerations
+
+1. **Dependency Depth**: Deep dependency chains can impact performance
+2. **Graph Complexity**: Complex graphs take longer to process
+3. **Caching**: The system caches resolved dependencies for performance
+
+## Best Practices
+
+1. **Minimize Dependencies**: Only depend on what you need
+2. **Keep Graphs Shallow**: Prefer wide, shallow dependency graphs over deep ones
+3. **Document Dependencies**: Clearly document all plugin dependencies
+4. **Test Edge Cases**: Test with missing or invalid dependencies
+5. **Monitor Performance**: Keep an eye on resolution time for large graphs

+# Plugin Dependencies
+
+## Overview
+
+The Custom Resolver system provides a powerful dependency management system that allows plugins to depend on the resolved values of other properties. This enables complex resolution strategies where the value of one property can influence how another property is resolved.
+
+## Key Concepts
+
+1. **Dependency Declaration**: Plugins declare their dependencies using the `dependencies` property
+2. **Type Safety**: Dependencies are type-checked at compile time
+3. **Automatic Resolution**: The system resolves dependencies in the correct order
+4. **Cycle Detection**: Circular dependencies are detected and reported
+
+## How It Works
+
+1. **Dependency Graph**: The system builds a directed acyclic graph (DAG) of plugin dependencies
+2. **Topological Sort**: Plugins are processed in an order that respects their dependencies
+3. **Dependency Injection**: Required dependencies are automatically injected into plugin methods
+4. **Lazy Resolution**: Dependencies are only resolved when needed
+
+## Example
+
+```typescript
+class TotalPricePlugin extends ResolverPlugin<TotalState, 'price' | 'tax'> {
+  readonly dependencies = ['price', 'tax'] as const;
+  
+  initialize(): TotalState {
+    return { total: 0 };
+  }
+  
+  update(
+    state: TotalState,
+    _newValue: unknown,
+    _delta: CollapsedDelta,
+    deps: DependencyStates
+  ): TotalState {
+    const price = deps.price as number;
+    const tax = deps.tax as number;
+    return { total: price + tax };
+  }
+  
+  resolve(state: TotalState): number {
+    return state.total;
+  }
+}
+```
+
+## Best Practices
+
+1. **Minimal Dependencies**: Only declare dependencies that are actually needed
+2. **Acyclic Dependencies**: Keep the dependency graph acyclic
+3. **Document Dependencies**: Clearly document what each dependency is used for
+4. **Handle Missing Dependencies**: Gracefully handle cases where dependencies might be undefined

+# Type-Safe Dependencies
+
+## Overview
+
+The Custom Resolver system leverages TypeScript's type system to provide compile-time safety for plugin dependencies. This ensures that:
+
+1. Only declared dependencies can be accessed
+2. Dependencies are properly typed
+3. Refactoring is safer with compiler support
+4. Common errors are caught during development
+
+## How It Works
+
+The `ResolverPlugin` interface uses TypeScript generics to enforce type safety:
+
+```typescript
+interface ResolverPlugin<T = unknown, D extends string = never> {
+  readonly name: string;
+  readonly dependencies?: readonly D[];
+  
+  // ... methods receive properly typed dependencies
+  update(
+    currentState: T,
+    newValue: PropertyTypes,
+    delta: CollapsedDelta,
+    dependencies: DependencyStates
+  ): T;
+}
+
+type DependencyStates = {
+  [K in D]: unknown;
+};
+```
+
+## Declaring Dependencies
+
+Dependencies are declared as a readonly array of string literals:
+
+```typescript
+class MyPlugin extends ResolverPlugin<MyState, 'dep1' | 'dep2'> {
+  readonly dependencies = ['dep1', 'dep2'] as const;
+  
+  // ... implementation
+}
+```
+
+### Type Inference
+
+Using `as const` with the dependencies array ensures TypeScript infers the most specific type possible:
+
+```typescript
+// Type is readonly ["dep1", "dep2"]
+readonly dependencies = ['dep1', 'dep2'] as const;
+```
+
+## Accessing Dependencies
+
+Dependencies are accessed through the `dependencies` parameter in plugin methods:
+
+```typescript
+update(
+  state: MyState,
+  _newValue: unknown,
+  _delta: CollapsedDelta,
+  deps: DependencyStates
+): MyState {
+  // TypeScript knows price and tax are available
+  const price = deps.price as number;
+  const tax = deps.tax as number;
+  
+  // This would be a TypeScript error:
+  // const unknown = deps.unknown; // Error: Property 'unknown' does not exist
+  
+  return { /* ... */ };
+}
+```
+
+## Type Assertions
+
+Since dependency values are typed as `unknown`, you'll need to use type assertions or type guards:
+
+```typescript
+// Using type assertion
+const price = deps.price as number;
+
+// Using type guard
+if (typeof deps.price === 'number') {
+  // deps.price is now typed as number
+}
+```
+
+## Best Practices
+
+1. **Use `as const`** for dependency arrays to get the most specific type
+2. **Narrow types** when accessing dependency values
+3. **Document expected types** of dependencies in JSDoc
+4. **Handle undefined** values when dependencies might be missing
+
+## Common Patterns
+
+### Optional Dependencies
+
+```typescript
+class MyPlugin extends ResolverPlugin<MyState, 'required' | 'optional?'> {
+  readonly dependencies = ['required', 'optional?'] as const;
+  
+  update(_state: MyState, _value: unknown, _delta: CollapsedDelta, deps: any) {
+    const required = deps.required as number; // Always present
+    const optional = deps['optional?'] as number | undefined; // Might be undefined
+    
+    // ...
+  }
+}
+```
+
+### Multiple Dependencies with Same Type
+
+```typescript
+type PriceDependencies = 'price1' | 'price2' | 'price3';
+
+class PriceAggregator extends ResolverPlugin<PriceState, PriceDependencies> {
+  readonly dependencies: readonly PriceDependencies[] = ['price1', 'price2', 'price3'] as const;
+  
+  update(_state: PriceState, _value: unknown, _delta: CollapsedDelta, deps: any) {
+    const prices = this.dependencies
+      .map(dep => deps[dep] as number | undefined)
+      .filter((p): p is number => p !== undefined);
+    
+    // ...
+  }
+}
+```
+
+## Troubleshooting
+
+### Type Errors
+
+- **Missing Dependencies**: Ensure all dependencies are properly declared in the type parameter
+- **Incorrect Types**: Verify type assertions match the expected types
+- **Readonly Arrays**: Use `readonly` and `as const` for dependency arrays
+
+### Runtime Errors
+
+- **Undefined Dependencies**: Check if a dependency exists before using it
+- **Type Mismatches**: Validate types at runtime when necessary
+- **Circular Dependencies**: Ensure your dependency graph is acyclic

+# Built-in Plugins
+
+## Overview
+
+The Custom Resolver system includes several built-in plugins that implement common resolution strategies. These can be used directly or as examples for creating custom plugins.
+
+## Available Plugins
+
+### Last Write Wins
+
+Keeps the most recent value based on timestamp.
+
+```typescript
+const resolver = new CustomResolver(view, {
+  myProperty: new LastWriteWinsPlugin()
+});
+```
+
+### First Write Wins
+
+Keeps the first non-null value seen.
+
+```typescript
+const resolver = new CustomResolver(view, {
+  myProperty: new FirstWriteWinsPlugin()
+});
+```
+
+### Concatenation
+
+Combines string values with a separator.
+
+```typescript
+const resolver = new CustomResolver(view, {
+  fullName: new ConcatenationPlugin({
+    separator: ' ',
+    sort: true  // Sort values before concatenation
+  })
+});
+```
+
+### Majority Vote
+
+Selects the most common value.
+
+```typescript
+const resolver = new CustomResolver(view, {
+  status: new MajorityVotePlugin({
+    minVotes: 2  // Minimum votes required to select a winner
+  })
+});
+```
+
+### Minimum Value
+
+Tracks the minimum numeric value.
+
+```typescript
+const resolver = new CustomResolver(view, {
+  minPrice: new MinPlugin()
+});
+```
+
+### Maximum Value
+
+Tracks the maximum numeric value.
+
+```typescript
+const resolver = new CustomResolver(view, {
+  maxScore: new MaxPlugin()
+});
+```
+
+## Plugin Options
+
+| Plugin | Options | Default | Description |
+|--------|---------|---------|-------------|
+| `ConcatenationPlugin` | `separator: string`<br>`sort: boolean` | `', '`<br>`false` | Separator between values and whether to sort |
+| `MajorityVotePlugin` | `minVotes: number` | `1` | Minimum votes needed to select a winner |
+| `LastWriteWins`<br>`FirstWriteWins`<br>`MinPlugin`<br>`MaxPlugin` | None | N/A | No configuration options |
+
+## Choosing the Right Plugin
+
+- Use `LastWriteWins` for simple timestamp-based resolution
+- Use `FirstWriteWins` to preserve the initial value
+- Use `ConcatenationPlugin` for combining string values
+- Use `MajorityVote` for consensus-based resolution
+- Use `MinPlugin`/`MaxPlugin` for numeric ranges

+# Creating Custom Plugins
+
+## Overview
+
+Custom plugins allow you to implement custom resolution logic for your specific use case. This guide walks through creating a new plugin from scratch.
+
+## Basic Plugin Structure
+
+A minimal plugin must implement the `ResolverPlugin` interface:
+
+```typescript
+import { ResolverPlugin } from '../resolver';
+
+class MyPlugin extends ResolverPlugin<MyState> {
+  
+  initialize(): MyState {
+    // Return initial state
+    return { /* ... */ };
+  }
+  
+  update(
+    currentState: MyState,
+    newValue: unknown,
+    delta: CollapsedDelta,
+    dependencies: {}
+  ): MyState {
+    // Update state based on new value
+    return { /* updated state */ };
+  }
+  
+  resolve(state: MyState): unknown {
+    // Return the resolved value
+    return /* resolved value */;
+  }
+}
+```
+
+## Adding Dependencies
+
+To depend on other properties, specify the dependency types:
+
+```typescript
+class DiscountedPricePlugin extends ResolverPlugin<DiscountState, 'basePrice' | 'discount'> {
+  readonly dependencies = ['basePrice', 'discount'] as const;
+  
+  initialize(): DiscountState {
+    return { finalPrice: 0 };
+  }
+  
+  update(
+    state: DiscountState,
+    _newValue: unknown,
+    _delta: CollapsedDelta,
+    deps: DependencyStates
+  ): DiscountState {
+    const basePrice = deps.basePrice as number;
+    const discount = deps.discount as number;
+    return { finalPrice: basePrice * (1 - discount) };
+  }
+  
+  resolve(state: DiscountState): number {
+    return state.finalPrice;
+  }
+}
+```
+
+## Best Practices
+
+1. **Immutable State**: Always return new state objects instead of mutating
+2. **Pure Functions**: Keep update and resolve methods pure and side-effect free
+3. **Error Handling**: Handle unexpected input gracefully
+4. **Type Safety**: Use TypeScript types to catch errors early
+5. **Documentation**: Document your plugin's behavior and requirements
+
+## Testing Your Plugin
+
+Create tests to verify your plugin's behavior:
+
+```typescript
+describe('DiscountedPricePlugin', () => {
+  let view: LosslessView;
+  let resolver: CustomResolver;
+  
+  beforeEach(() => {
+    view = new LosslessView();
+    resolver = new CustomResolver(view, {
+      basePrice: new LastWriteWinsPlugin(),
+      discount: new LastWriteWinsPlugin(),
+      finalPrice: new DiscountedPricePlugin()
+    });
+  });
+  
+  test('applies discount to base price', () => {
+    // Test your plugin's behavior
+  });
+});
+```
+
+## Advanced Topics
+
+### Handling Complex Dependencies
+
+For plugins with complex dependency requirements, you can use the `dependencies` array to declare all required properties and access them in a type-safe way through the `dependencies` parameter.
+
+### Performance Considerations
+
+- Keep state updates minimal and efficient
+- Avoid expensive computations in the update method
+- Consider memoization for expensive resolve operations
+
+### Debugging
+
+Add logging to track state changes and resolution:
+
+```typescript
+update(currentState: MyState, newValue: unknown): MyState {
+  debug('Updating with:', { currentState, newValue });
+  // ...
+}
+```

+# Resolver Plugins
+
+## Overview
+
+Resolver plugins implement the core resolution logic for properties in the Custom Resolver system. Each plugin is responsible for:
+
+1. Initializing its internal state
+2. Processing updates to the property
+3. Resolving the final value from the current state
+
+## Plugin Lifecycle
+
+1. **Initialization**: When a resolver is created, each plugin's `initialize()` method is called to set up its initial state.
+2. **Update Processing**: For each new delta, the `update()` method is called with the current state, new value, and any dependency states.
+3. **Resolution**: The `resolve()` method is called to produce the final value from the current state.
+
+## Built-in Plugins
+
+The system includes several common resolution strategies:
+
+- [Last Write Wins](./builtin-plugins.md#last-write-wins)
+- [First Write Wins](./builtin-plugins.md#first-write-wins)
+- [Concatenation](./builtin-plugins.md#concatenation)
+- [Majority Vote](./builtin-plugins.md#majority-vote)
+- [Minimum Value](./builtin-plugins.md#min)
+- [Maximum Value](./builtin-plugins.md#max)
+
+## Creating Custom Plugins
+
+See the [Creating Custom Plugins](./creating-plugins.md) guide for detailed information on implementing your own resolver plugins.

+# Delta Patterns in Rhizome-Node
+
+This document outlines the distinct delta patterns identified in the Rhizome-Node test suite.
+
+## 1. Basic Entity Creation
+```typescript
+createDelta('creator', 'host')
+  .setProperty('entity1', 'name', 'Alice', 'user')
+  .buildV1();
+```
+
+## 2. Relationship Creation
+```typescript
+createDelta('creator', 'host')
+  .addPointer('users', 'alice', 'friends')
+  .addPointer('friend', 'bob')
+  .addPointer('type', 'friendship')
+  .buildV1();
+```
+
+## 3. Transaction-Enabled Deltas
+```typescript
+createDelta('user1', 'host1')
+  .inTransaction('tx123')
+  .setProperty('doc1', 'status', 'draft')
+  .buildV1();
+```
+
+## 4. Negation Deltas
+```typescript
+// Creating a negation delta
+const delta = createDelta('user1', 'host1').buildV1();
+const negation = createDelta('moderator', 'host1').negate(delta.id).buildV1();
+```
+
+## 5. Temporal Deltas
+```typescript
+createDelta('user1', 'host1')
+  .withTimestamp(1624233600000)
+  .setProperty('entity1', 'score', 100, 'game')
+  .buildV1();
+```
+
+## 6. Multi-Property Deltas
+```typescript
+createDelta('user1', 'host1')
+  .setProperty('entity1', 'title', 'Hello World', 'post')
+  .setProperty('entity1', 'content', 'This is a test', 'post')
+  .setProperty('entity1', 'published', true, 'post')
+  .buildV1();
+```
+
+## 7. Reference-Only Deltas
+```typescript
+createDelta('system', 'host1')
+  .addPointer('posts', 'post1', 'recent')
+  .buildV1();
+```
+
+## 8. Bulk Operation Deltas
+```typescript
+// Multiple entities in a single delta
+createDelta('batch', 'host1')
+  .setProperty('user1', 'status', 'active', 'user')
+  .setProperty('user2', 'status', 'inactive', 'user')
+  .buildV1();
+```
+
+## 9. Versioned Deltas
+```typescript
+// V1 format
+createDelta('a', 'h').buildV1();
+// V2 format
+createDelta('a', 'h').buildV2();
+```
+
+## Key Observations
+- Most deltas follow a fluent builder pattern
+- Deltas can be composed of multiple operations (setProperty, addPointer, etc.)
+- Support for both V1 and V2 delta formats
+- Strong typing and schema validation is commonly used
+- Transaction support is built into the delta creation process
+- Temporal aspects can be explicitly controlled

+# Resolvers (Views)
+
+The workhorse of this system is likely going to be our lossy views.
+This is where the computation likely generally occurs.
+
+So, let's talk about how to create a view. 
+
+A lossy view initializes from a given lossless view.
+The lossless view dispatches events when entity properties are updated.
+
+View semantics are similar to map-reduce, resolvers in Redux, etc. 
+
+The key is to identify your accumulator object. 
+Your algorithm SHOULD be implemented so that the reducer is a pure function.
+All state must therefore be stored in the accumulator.

+# Schema Validation in Rhizome-Node
+
+This document explains how schema validation works with deltas in Rhizome-Node.
+
+## Overview
+
+Schema validation in Rhizome-Node is enforced at the `TypedCollection` level when using the `put` method, which validates data before creating deltas. This means:
+
+1. **Local Changes**: When you use `collection.put()`, the data is validated against the schema before any deltas are created and ingested.
+2. **Peer Changes**: Deltas received from other peers are ingested without validation by default, which means invalid data can enter the system.
+3. **Validation Tracking**: The system tracks which entities are valid/invalid after ingestion.
+
+## Example Usage
+
+```typescript
+// 1. Define a schema for users
+const userSchema = SchemaBuilder
+  .create('user')
+  .name('User')
+  .property('name', PrimitiveSchemas.requiredString())
+  .property('email', PrimitiveSchemas.email())
+  .property('age', PrimitiveSchemas.integer({ minimum: 0 }))
+  .required('name')
+  .build();
+
+// 2. Create a typed collection with strict validation
+const collection = new TypedCollectionImpl<{
+  name: string;
+  email?: string;
+  age?: number;
+}>('users', userSchema, schemaRegistry, {
+  strictValidation: true // Enable strict validation
+});
+
+// Connect to the node
+collection.rhizomeConnect(node);
+
+// 3. Local changes - validated on put()
+// Valid usage - will pass schema validation
+await collection.put('user1', { 
+  name: 'Alice', 
+  email: 'alice@example.com',
+  age: 30
+});
+
+// Invalid usage - will throw SchemaValidationError
+await expect(collection.put('user2', {
+  email: 'invalid-email', // Invalid email format
+  age: -5                 // Negative age
+})).rejects.toThrow(SchemaValidationError);
+
+// 4. Peer data - ingested without validation by default
+const unsafeDelta = createDelta('peer1', 'peer1')
+  .setProperty('user3', 'name', 'Bob', 'users')
+  .setProperty('user3', 'age', 'not-a-number', 'users')
+  .buildV1();
+
+// This will be ingested without validation
+node.lossless.ingestDelta(unsafeDelta);
+
+// 5. Check validation status after the fact
+const stats = collection.getValidationStats();
+debug(`Valid: ${stats.validEntities}, Invalid: ${stats.invalidEntities}`);
+
+// Get details about invalid entities
+const invalidUsers = collection.getInvalidEntities();
+invalidUsers.forEach(user => {
+  debug(`User ${user.entityId} is invalid:`, user.errors);
+});
+```
+
+## Key Points
+
+### Validation Timing
+- Schema validation happens in `TypedCollection.put()` before deltas are created
+- Deltas from peers are ingested without validation by default
+
+### Validation Modes
+- `strictValidation: true`: Throws errors on invalid data (recommended for local changes)
+- `strictValidation: false`: Allows invalid data but tracks it (default)
+
+### Monitoring
+- Use `getValidationStats()` to get counts of valid/invalid entities
+- Use `getInvalidEntities()` to get detailed error information
+
+### Best Practices
+- Always validate data before creating deltas when accepting external input
+- Use `strictValidation: true` for collections where data integrity is critical
+- Monitor validation statistics in production to detect data quality issues
+- Consider implementing a validation layer for peer data if needed

+# Test Helpers
+
+This document provides documentation for the test helper functions available in the Rhizome Node test suite.
+
+## `testResolverWithPlugins`
+
+A helper function for testing custom resolvers with plugins and a sequence of deltas.
+
+### Import
+
+```typescript
+import { testResolverWithPlugins, createTestDelta } from '@test-helpers/resolver-test-helper';
+```
+
+### Signature
+
+```typescript
+function testResolverWithPlugins<T>({
+  entityId,
+  plugins,
+  deltas,
+  expectedResult
+}: {
+  entityId: string;
+  plugins: Record<string, ResolverPlugin>;
+  deltas: Delta[];
+  expectedResult: (result: T) => void;
+}): Promise<void>;
+```
+
+### Parameters
+
+- `entityId`: The ID of the entity to test
+- `plugins`: An object mapping property names to their respective resolver plugins
+- `deltas`: An array of `Delta` objects to process
+- `expectedResult`: A callback function that receives the resolved result for assertions
+
+### Return Value
+
+A promise that resolves when the test is complete.
+
+### Example Usage
+
+```typescript
+import { testResolverWithPlugins, createTestDelta } from '@test-helpers/resolver-test-helper';
+import { ConcatenationPlugin } from '@src/views/resolvers/custom-resolvers/builtin-plugins';
+
+describe('MyCustomResolver', () => {
+  test('should process deltas correctly', async () => {
+    // Run test with plugins and deltas
+    await testResolverWithPlugins({
+      entityId: 'entity1',
+      plugins: {
+        myProperty: new ConcatenationPlugin()
+      },
+      deltas: [
+        createTestDelta('user1', 'host1')
+          .setProperty('entity1', 'myProperty', 'value1')
+          .buildV1(),
+        createTestDelta('user1', 'host1')
+          .setProperty('entity1', 'myProperty', 'value2')
+          .buildV1()
+      ],
+      expectedResult: (result) => {
+        expect(result.properties.myProperty).toBe('value1 value2');
+      }
+    });
+  });
+});
+```
+
+## `createTestDelta`
+
+A helper function for creating test deltas with a fluent API.
+
+### Example Usage
+
+```typescript
+const delta = createTestDelta('user1', 'host1')
+  .withTimestamp(1000)
+  .setProperty('entity1', 'tags', 'red', 'color1')
+  .buildV1();
+```
+
+## How It Works
+
+1. Creates a new `Lossless` instance for the test
+2. Sets up a `CustomResolver` with the provided plugins
+3. Ingests all provided deltas into the `Lossless` instance
+4. Retrieves a view for the specified entity
+5. Processes the view through the resolver
+6. Calls the `expectedResult` callback with the resolved entity
+
+## Best Practices
+
+- Use this helper when testing custom resolvers with plugins
+- The helper handles all setup and teardown of test resources
+- Use `createTestDelta` for consistent delta creation in tests
+- The helper ensures type safety between the resolver and the expected result type
+- Each test gets a fresh `Lossless` instance automatically
