# 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

    #![allow(unused)]
    fn main() {
    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

    {
      documentSearch(query: {
        text_query: "authentication"
        limit: 10
      }) {
        results { id title relevance_score }
      }
    }

3. Frontend ↔ WebSocket Events

    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)

    #![allow(unused)]
    fn main() {
    // 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)

    # 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)

    // 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:

    # 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

    #![allow(unused)]
    fn main() {
    // 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)

    #![allow(unused)]
    fn main() {
    // 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)

    #![allow(unused)]
    fn main() {
    // 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

    # 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
