+# VIEW-000: Foundation & Shared Utilities - CHANGELOG
+
+## Phases 1-3 Completed ✅
+
+**Date:** January 3, 2026  
+**Duration:** ~2 hours  
+**Status:** Core graph analysis utilities complete
+
+---
+
+## Summary
+
+Implemented the foundational graph analysis utilities that all visualization views will depend on. These utilities enable:
+
+- **Connection chain tracing** - Follow data flow upstream/downstream through the graph
+- **Cross-component resolution** - Track how components use each other and resolve component boundaries
+- **Node categorization** - Semantic grouping of nodes by purpose (visual, data, logic, events, etc.)
+- **Duplicate detection** - Find potential naming conflicts and issues
+
+---

+└── duplicateDetection.ts       # Duplicate node detection
+```
+
+---
+
+## Phase 1: Core Traversal Utilities ✅
+
+### `types.ts` - Type Definitions
+
+Comprehensive TypeScript interfaces for all graph analysis operations:
+
+- `ConnectionRef` - Reference to a connection between ports
+- `ConnectionPath` - A point in a connection traversal path
+- `TraversalResult` - Result of tracing a connection chain
+- `NodeSummary`, `ConnectionSummary`, `ComponentSummary` - Data summaries
+- `ComponentUsage`, `ExternalConnection` - Cross-component types
+- `DuplicateGroup`, `ConflictAnalysis` - Duplicate detection types
+- `CategorizedNodes` - Node categorization results
+
+### `traversal.ts` - Graph Traversal Functions
+
+**Key Functions:**
+
+1. **`traceConnectionChain()`** - Trace connections upstream or downstream
+
+   - Follows connection chains through multiple nodes
+   - Configurable max depth, branch handling
+   - Can stop at specific node types
+   - Detects cycles and component boundaries
+   - Returns complete path with termination reason
+
+2. **`getConnectedNodes()`** - Get direct neighbors of a node
+
+   - Returns both input and output connections
+   - Deduplicated results
+
+3. **`getPortConnections()`** - Get all connections for a specific port
+
+   - Filters by port name and direction
+   - Returns ConnectionRef array
+
+4. **`buildAdjacencyList()`** - Build graph representation
+
+   - Returns Map of node IDs to their connections
+   - Useful for graph algorithms
+
+5. **`getAllConnections()`** - Get all connections in component
+
+6. **`findNodesOfType()`** - Find all nodes of a specific typename
+
+**Example Usage:**
+
+```typescript
+import { traceConnectionChain } from '@noodl-utils/graphAnalysis';
+
+// Find what feeds into a Text node's 'text' input
+const result = traceConnectionChain(component, textNodeId, 'text', 'upstream');
+
+console.log(
+  'Data flows through:',
+  result.path.map((p) => p.node.label)
+);
+// Output: ['Text', 'Expression', 'Variable']
+```
+
+---
+
+## Phase 2: Cross-Component Resolution ✅
+
+### `crossComponent.ts` - Component Boundary Handling
+
+**Key Functions:**
+
+1. **`findComponentUsages()`** - Find where a component is used
+
+   - Searches entire project
+   - Returns component instance locations
+   - Includes connected port information
+
+2. **`resolveComponentBoundary()`** - Trace through Component Inputs/Outputs
+
+   - Resolves what connects to a Component Inputs node from parent
+   - Resolves what Component Outputs connects to in parent
+   - Returns external connection information
+
+3. **`buildComponentDependencyGraph()`** - Project component relationships
+
+   - Returns nodes (components) and edges (usage)
+   - Counts how many times each component uses another
+
+4. **`isComponentUsed()`** - Check if component is instantiated anywhere
+
+5. **`findUnusedComponents()`** - Find components not used in project
+
+   - Excludes root component
+   - Useful for cleanup
+
+6. **`getComponentDepth()`** - Get hierarchy depth
+   - Depth 0 = root component
+   - Depth 1 = used by root
+   - Returns -1 if unreachable
+
+**Example Usage:**
+
+```typescript
+import { findComponentUsages, buildComponentDependencyGraph } from '@noodl-utils/graphAnalysis';
+
+// Find all places "UserCard" is used
+const usages = findComponentUsages(project, 'UserCard');
+usages.forEach((usage) => {
+  console.log(`Used in ${usage.usedIn.name}`);
+});
+
+// Build project-wide component graph
+const graph = buildComponentDependencyGraph(project);
+console.log(`Project has ${graph.nodes.length} components`);
+```
+
+---
+
+## Phase 3: Categorization & Duplicate Detection ✅
+
+### `categorization.ts` - Semantic Node Grouping
+
+**Categories:**
+
+- `visual` - Groups, Text, Image, Page Stack, etc.
+- `data` - Variables, Objects, Arrays
+- `logic` - Conditions, Expressions, Switches
+- `events` - Send/Receive Event, Component I/O
+- `api` - REST, Cloud Functions, JavaScript Function
+- `navigation` - Page Router, Navigate
+- `animation` - Value Changed, Did Mount, etc.
+- `utility` - Everything else
+
+**Key Functions:**
+
+1. **`categorizeNodes()`** - Categorize all nodes in component
+
+   - Returns nodes grouped by category and by type
+   - Includes totals array
+
+2. **`getNodeCategory()`** - Get category for a node type
+
+3. **`isVisualNode()`**, **`isDataSourceNode()`**, **`isLogicNode()`**, **`isEventNode()`** - Type check helpers
+
+4. **`getNodeCategorySummary()`** - Get category counts sorted by frequency
+
+5. **`getNodeTypeSummary()`** - Get type counts with categories
+
+**Example Usage:**
+
+```typescript
+import { categorizeNodes, getNodeCategorySummary } from '@noodl-utils/graphAnalysis';
+
+const categorized = categorizeNodes(component);
+categorized.totals.forEach(({ category, count }) => {
+  console.log(`${category}: ${count} nodes`);
+});
+// Output:
+// visual: 45 nodes
+// data: 12 nodes
+// logic: 8 nodes
+// ...
+```
+
+### `duplicateDetection.ts` - Find Potential Issues
+
+**Key Functions:**
+
+1. **`findDuplicatesInComponent()`** - Find nodes with same name + type
+
+   - Groups by typename and label
+   - Assigns severity based on node type:
+     - `info` - General duplicates
+     - `warning` - Data nodes (Variables, Objects, Arrays)
+     - `error` - Event nodes with same channel name
+
+2. **`findDuplicatesInProject()`** - Find duplicates across all components
+
+3. **`analyzeDuplicateConflicts()`** - Detect actual conflicts
+
+   - `data-race` - Multiple Variables writing to same output
+   - `name-collision` - Multiple Events with same channel
+   - `state-conflict` - Multiple Objects/Arrays with same name
+
+4. **`findSimilarlyNamedNodes()`** - Find typo candidates
+   - Uses Levenshtein distance for similarity
+   - Configurable threshold (default 0.8)
+
+**Example Usage:**
+
+```typescript
+import { findDuplicatesInComponent, analyzeDuplicateConflicts } from '@noodl-utils/graphAnalysis';
+
+const duplicates = findDuplicatesInComponent(component);
+const conflicts = analyzeDuplicateConflicts(duplicates);
+
+conflicts.forEach((conflict) => {
+  console.warn(`${conflict.conflictType}: ${conflict.description}`);
+});
+// Output:
+// data-race: Multiple variables named "userData" connect to the same output node. Last write wins.
+```
+

+
+## Code Quality
+
+- ✅ No `TSFixme` types used
+- ✅ Comprehensive JSDoc comments on all public functions
+- ✅ TypeScript strict mode compliance
+- ✅ Example code in all JSDoc blocks
+- ✅ Defensive null checks throughout
+- ✅ Pure functions (no side effects)
+- ✅ Clean public API via index.ts
+
+---
+
+## Testing Strategy
+
+### Manual Testing Performed
+
+- ✅ All files compile without TypeScript errors
+- ✅ Functions can be imported via public API
+- ✅ Type definitions properly exported
+
+### Integration Testing (Next Steps)
+
+When VIEW-001 is implemented, these utilities should be tested with:
+
+- Large projects (100+ components, 1000+ nodes)
+- Deep component hierarchies (5+ levels)
+- Complex connection chains (10+ hops)
+- Edge cases (cycles, disconnected graphs, missing components)
+
+---
+
+## Deferred Work
+
+### Phase 4: View Infrastructure
+
+**Status:** Deferred until VIEW-001 requirements are known
+
+The README proposes three UI patterns:
+
+1. **Meta View Tabs** - Replace canvas (Topology Map, Trigger Chain)
+2. **Sidebar Panels** - Alongside canvas (Census, X-Ray)
+3. **Canvas Overlays** - Enhance canvas (Data Lineage, Semantic Layers)
+
+**Decision:** Build infrastructure when we know which pattern VIEW-001 needs. This avoids building unused code.
+
+### Phase 6: Debug Infrastructure Documentation
+
+**Status:** Deferred until VIEW-003 (Trigger Chain Debugger) needs it
+
+Tasks to complete later:
+
+- Document how DebugInspector works
+- Document runtime→canvas highlighting mechanism
+- Document runtime event emission
+- Create `dev-docs/reference/DEBUG-INFRASTRUCTURE.md`
+
+---
+
+## Usage Example (Complete Workflow)
+
+```typescript
+import {
+  // Traversal
+  traceConnectionChain,
+  getConnectedNodes,
+  // Cross-component
+  findComponentUsages,
+  buildComponentDependencyGraph,
+  // Categorization
+  categorizeNodes,
+  getNodeCategorySummary,
+  // Duplicate detection
+  findDuplicatesInComponent,
+  analyzeDuplicateConflicts
+} from '@noodl-utils/graphAnalysis';
+
+// 1. Analyze component structure
+const categories = getNodeCategorySummary(component);
+console.log('Most common category:', categories[0].category);
+
+// 2. Find data flow paths
+const dataFlow = traceConnectionChain(component, textNodeId, 'text', 'upstream', {
+  stopAtTypes: ['Variable', 'Object']
+});
+console.log('Data source:', dataFlow.path[dataFlow.path.length - 1].node.label);
+
+// 3. Check for issues
+const duplicates = findDuplicatesInComponent(component);
+const conflicts = analyzeDuplicateConflicts(duplicates);
+if (conflicts.length > 0) {
+  console.warn(`Found ${conflicts.length} potential conflicts`);
+}
+
+// 4. Analyze project structure
+const usages = findComponentUsages(project, 'UserCard');
+console.log(`UserCard used in ${usages.length} places`);
+
+const graph = buildComponentDependencyGraph(project);
+console.log(`Project has ${graph.edges.length} component relationships`);
+```
+
+---
+
+## Next Steps
+
+### Immediate (VIEW-001)
+
+1. **Review VIEW-001 requirements** to determine UI pattern needed
+2. **Build view infrastructure** based on actual needs
+3. **Implement VIEW-001** using these graph analysis utilities
+
+### Future Views
+
+- VIEW-002: Component X-Ray (uses `categorizeNodes`, `getConnectedNodes`)
+- VIEW-003: Trigger Chain Debugger (needs Phase 6 debug docs first)
+- VIEW-004: Node Census (uses `categorizeNodes`, `findDuplicatesInComponent`)
+- VIEW-005: Data Lineage (uses `traceConnectionChain`, `resolveComponentBoundary`)
+- VIEW-006: Impact Radar (uses `findComponentUsages`, `buildComponentDependencyGraph`)
+- VIEW-007: Semantic Layers (uses `categorizeNodes`, canvas overlay pattern)
+
