# Doc-Lifecycle-Manager Integration Guide

## Overview

**doc-lifecycle-manager** (external project) provides complete documentation lifecycle management for VAPORA, including classification, consolidation, semantic search, real-time updates, and enterprise security features.

**Project Location**: External project (doc-lifecycle-manager)
**Status**: ✅ **Enterprise-Ready**
**Tests**: 155/155 passing | Zero unsafe code

---

## What is doc-lifecycle-manager

A comprehensive Rust-based system that handles documentation throughout its entire lifecycle:

### Core Capabilities (Phases 1-3)
- **Automatic Classification**: Categorizes docs (vision, design, specs, ADRs, guides, testing, archive)
- **Duplicate Detection**: Finds similar documents with TF-IDF analysis
- **Semantic RAG Indexing**: Vector embeddings for semantic search
- **mdBook Generation**: Auto-generates documentation websites

### Enterprise Features (Phases 4-7)
- **GraphQL API**: Semantic document queries with pagination
- **Real-Time Events**: WebSocket streaming of doc updates
- **Distributed Tracing**: OpenTelemetry with W3C Trace Context
- **Security**: mTLS with automatic certificate rotation
- **Performance**: Comprehensive benchmarking with percentiles
- **Persistence**: SurrealDB backend (feature-gated)

### Component Integration Points

**1. Documenter Agent ↔ doc-lifecycle-manager**
```rust
use vapora_doc_lifecycle::prelude::*;

// On task completion
async fn on_task_completed(task_id: &str) {
    let config = PluginConfig::default();
    let mut docs = DocumenterIntegration::new(config)?;
    docs.on_task_completed(task_id).await?;
}
```

**2. Frontend ↔ GraphQL API**
```graphql
{
  documentSearch(query: {
    text_query: "authentication"
    limit: 10
  }) {
    results { id title relevance_score }
  }
}
```

**3. Frontend ↔ WebSocket Events**
```javascript
const ws = new WebSocket("ws://vapora/doc-events");
ws.onmessage = (event) => {
  const { event_type, payload } = JSON.parse(event.data);
  // Update UI on document_indexed, document_updated, etc.
};
```

**4. Agent-to-Agent ↔ NATS JetStream**
```
Task Completed Event
  → Documenter Agent (NATS)
    → Classify + Index
      → Broadcast DocumentIndexed Event
        → All Agents notified
```

## How to Use in VAPORA

### 1. Basic Integration (Documenter Agent)

```rust
// In vapora-backend/documenter_agent.rs

use vapora_doc_lifecycle::prelude::*;

impl DocumenterAgent {
    async fn process_task(&self, task: Task) -> Result<()> {
        let config = PluginConfig::default();
        let mut integration = DocumenterIntegration::new(config)?;

        // Automatically classifies, indexes, and generates docs
        integration.on_task_completed(&task.id).await?;

        Ok(())
    }
}
```

### 2. GraphQL Queries (Frontend/Agents)

```graphql
# Search for documentation
query SearchDocs($query: String!) {
  documentSearch(query: {
    text_query: $query
    limit: 10
    visibility: "Public"
  }) {
    results {
      id
      title
      path
      relevance_score
      preview
    }
    total_count
    has_more
  }
}

# Get specific document
query GetDoc($id: ID!) {
  document(id: $id) {
    id
    title
    content
    metadata {
      created_at
      updated_at
      owner_id
    }
  }
}
```

### 3. Real-Time Updates (Frontend)

```javascript
// Connect to doc-lifecycle WebSocket
const docWs = new WebSocket('ws://vapora-api/doc-lifecycle/events');

// Subscribe to document changes
docWs.onopen = () => {
  docWs.send(JSON.stringify({
    type: 'subscribe',
    event_types: ['document_indexed', 'document_updated', 'search_index_rebuilt'],
    min_priority: 5
  }));
};

// Handle updates
docWs.onmessage = (event) => {
  const message = JSON.parse(event.data);

  if (message.event_type === 'document_indexed') {
    console.log('New doc indexed:', message.payload);
    // Refresh documentation view
  }
};
```

### 4. Distributed Tracing

All operations are automatically traced:

```
GET /api/documents?search=auth
  trace_id: 0af7651916cd43dd8448eb211c80319c
  span_id: b7ad6b7169203331

  ├─ graphql_resolver [15ms]
  │  ├─ rbac_check [2ms]
  │  └─ semantic_search [12ms]
  └─ response [1ms]
```

### 5. mTLS Security

Service-to-service communication is secured:

```yaml
# Kubernetes secret for certs
apiVersion: v1
kind: Secret
metadata:
  name: doc-lifecycle-certs
data:
  server.crt: <base64>
  server.key: <base64>
  ca.crt: <base64>
```

## VAPORA Agent Integration

### Documenter Agent

```rust
// Processes documentation tasks
pub struct DocumenterAgent {
    integration: DocumenterIntegration,
    nats: NatsEventHandler,
}

impl DocumenterAgent {
    pub async fn handle_task(&self, task: Task) -> Result<()> {
        // 1. Classify document
        self.integration.on_task_completed(&task.id).await?;

        // 2. Broadcast via NATS
        let event = DocsUpdatedEvent {
            task_id: task.id,
            doc_count: 5,
        };
        self.nats.publish_docs_updated(event).await?;

        Ok(())
    }
}
```

### Developer Agent (Uses Search)

```rust
// Searches for relevant documentation
pub struct DeveloperAgent;

impl DeveloperAgent {
    pub async fn find_relevant_docs(&self, task: Task) -> Result<Vec<DocumentResult>> {
        // GraphQL query for semantic search
        let query = DocumentQuery {
            text_query: Some(task.description),
            limit: Some(5),
            visibility: Some("Internal".to_string()),
            ..Default::default()
        };

        // Execute search
        resolver.resolve_document_search(query, user).await
    }
}
```

### CodeReviewer Agent (Uses Context)

```rust
// Uses documentation as context for reviews
pub struct CodeReviewerAgent;

impl CodeReviewerAgent {
    pub async fn review_with_context(&self, code: &str) -> Result<Review> {
        // Search for related documentation
        let docs = semantic_search(code_summary).await?;

        // Use docs as context in review
        let review = llm_client
            .review_code(code, &docs.to_context_string())
            .await?;

        Ok(review)
    }
}
```

## Performance & Scaling

### Expected Performance

| Operation | Latency | Throughput |
|-----------|---------|-----------|
| Classify doc | <10ms | 1000 docs/sec |
| GraphQL query | <200ms | 50 queries/sec |
| WebSocket broadcast | <20ms | 1000 events/sec |
| Semantic search | <100ms | 50 searches/sec |
| mTLS validation | <5ms | N/A |

### Resource Requirements

**Deployment Resources**:
- CPU: 2-4 cores (main service)
- Memory: 512MB-2GB
- Storage: 50GB (SurrealDB + vectors)

**NATS Requirements**:
- CPU: 1-2 cores
- Memory: 256MB-1GB
- Persistent volume: 20GB

---

## Monitoring & Observability

### Prometheus Metrics

```promql
# Error rate
rate(doc_lifecycle_errors_total[5m])

# Latency
histogram_quantile(0.99, doc_lifecycle_request_duration_seconds)

# Service availability
up{job="doc-lifecycle"}
```

### Distributed Tracing

Traces are sent to Jaeger in W3C format:

```
Trace: 0af7651916cd43dd8448eb211c80319c
├─ Span: graphql_resolver
│  ├─ Span: rbac_check
│  └─ Span: semantic_search
└─ Span: response
```

### Health Checks

```bash
# Liveness probe
curl http://doc-lifecycle:8080/health/live

# Readiness probe
curl http://doc-lifecycle:8080/health/ready
```
