# CRAPH Analysis
## Real-Time Collaboration Patterns (Limited Access)

**Research Date:** 2025-11-20
**Status:** ⚠️ Permission restrictions prevented full codebase analysis
**Available:** Git submodule status, directory structure inference

## Analysis Status

**Attempted Research:**
- Directory exploration: ❌ Blocked (permission restrictions)
- File reading: ❌ Blocked (permission restrictions)
- README analysis: ❌ Blocked (permission restrictions)

**Available Information:**
- Git status shows `craph` as modified submodule
- Location: `/Users/kooshapari/temp-PRODVERCEL/485/zentest/craph`
- Directory confirmed to exist

## Inferred Architecture (Based on Name & Common Patterns)

### Likely Technology Stack

**Name Analysis:** "craph" suggests **graph** + **collaborative** or **cr**eate + **graph**

**Typical Stack for Real-Time Graph Collaboration:**
- **Backend:** Node.js/TypeScript or Python
- **Graph DB:** Neo4j, ArangoDB, or in-memory graph
- **Real-Time:** WebSocket (Socket.IO, ws library) or WebRTC
- **Sync:** CRDT (Yjs, Automerge) or OT (ShareDB)
- **Frontend:** React/Vue with graph visualization (D3.js, Cytoscape.js)

### Probable Patterns (Industry Standard)

#### 1. WebSocket Real-Time Sync
```typescript
// Typical WebSocket server pattern
import WebSocket from 'ws'

const wss = new WebSocket.Server({ port: 8080 })

wss.on('connection', (ws, req) => {
  const userId = authenticate(req)

  ws.on('message', (message) => {
    const data = JSON.parse(message)

    if (data.type === 'graph.update') {
      // Broadcast to other clients
      wss.clients.forEach(client => {
        if (client !== ws && client.readyState === WebSocket.OPEN) {
          client.send(JSON.stringify(data))
        }
      })
    }
  })
})
```

#### 2. CRDT-Based Conflict Resolution
```typescript
// Typical Yjs integration
import * as Y from 'yjs'
import { WebsocketProvider } from 'y-websocket'

const ydoc = new Y.Doc()
const provider = new WebsocketProvider('ws://localhost:1234', 'craph-session', ydoc)

const graph = ydoc.getMap('graph')
graph.set('node-123', { type: 'task', title: 'Implement feature' })
// Automatic CRDT merge across clients
```

#### 3. Graph Database Queries
```cypher
// Typical Neo4j queries for graph traversal
// Find all dependencies
MATCH (task:Task {id: 'TASK-123'})-[:DEPENDS_ON*]->(dep:Task)
RETURN dep

// Find impact of change
MATCH (item:Item {id: 'REQ-001'})<-[:IMPLEMENTS*]-(affected)
RETURN affected
```

## Recommendations for Trace (Generic)

### If craph Uses CRDT:
✅ **Adopt:** Automatic conflict resolution for concurrent task updates
✅ **Use:** Yjs or Automerge for offline-first collaboration
✅ **Integrate:** WebSocket for real-time view updates

### If craph Uses Graph Database:
✅ **Adopt:** Neo4j for complex relationship queries
✅ **Use:** Cypher for dependency traversal
✅ **Integrate:** Graph algorithms for impact analysis

### If craph Uses WebRTC:
✅ **Adopt:** P2P data channels for live collaboration sessions
✅ **Use:** STUN/TURN for NAT traversal
✅ **Integrate:** WebRTC for real-time planning workshops

## Next Steps Required

To complete comprehensive craph analysis, need one of:

1. **Grant file read permissions** for Glob, Read, Bash commands
2. **Manually provide** key files:
   - `README.md`
   - `package.json` or `pyproject.toml`
   - Main server file
   - WebSocket/sync implementation files
3. **Share git repository URL** if craph is open source

**Status:** Incomplete due to access restrictions
**Recommendation:** Complete analysis after obtaining file access
