Cloud Session 2: Technical Integration Architecture

NaviDocs Yacht Sales Enhancement Roadmap

Session Type: Technical Integration Specialist Lead Agent: Sonnet (architecture + development) Swarm Size: 10 Haiku agents Token Budget: $20 (10K Sonnet + 60K Haiku) Output: Feature specs + integration architecture + sprint plan

---

Mission Statement

Design comprehensive technical architecture for NaviDocs yacht sales features, leveraging InfraFabric's IF.bus and multi-agent patterns. Create 4-week implementation roadmap with acceptance criteria.

---

Context (Read First)

Prerequisites:

1. Read intelligence/session-1/session-1-market-analysis.md
2. Read intelligence/session-1/session-1-handoff.md
3. Read /home/setup/navidocs/ARCHITECTURE_INTEGRATION_ANALYSIS.md (if accessible)

Current NaviDocs Tech Stack:

• Frontend: Vue 3 + Vite
• Backend: Express.js + SQLite
• Background: BullMQ + Redis
• Search: Meilisearch
• OCR: Tesseract + Google Vision
• Auth: JWT + bcrypt

Integration Gaps (from Session 1):

• No MLS/listing platform integration
• No sale workflow automation
• No expiration tracking (surveys, warranties)
• Limited notifications (only password reset)
• No collaboration features (e-signatures)

Your Tasks (Spawn 10 Haiku Agents in Parallel)

Agent 1: NaviDocs Codebase Analysis

Read Files:

• server/db/schema.sql - Database structure
• server/routes/*.js - API endpoints

Deliverable: Security remediation plan

Agent 8: Notification System Design

Design:

• Email notification service
• SMS alerts (warranty expiration, document missing)
• In-app notification center
• Push notifications (PWA)

Deliverable: Notification architecture with templates

Agent 9: Database Migration Plan

Create:

• Migration scripts for warranty tracking
• Charter mode fields (flag, crew, safety)
• Expiration tracking tables
• Collaboration features schema

Deliverable: SQL migrations + rollback scripts

Agent 10: Sprint Planning

Compile:

• Week 1-4 task breakdown
• Dependencies mapped (e.g., DB migrations before API work)
• Acceptance criteria per feature
• Testing strategy (unit, integration, E2E)

Deliverable: 4-week sprint plan with Gantt chart

IF.bus Integration Pattern

Event Bus Design

// server/services/event-bus.js
class EventBus {
  async publish(topic, event) {
    // Publish to Redis pub/sub
    // Trigger webhooks (Home Assistant)
    // Queue background jobs
    // Log to audit trail
  }

  async subscribe(topic, handler) {
    // Subscribe to Redis channel
    // Handle incoming events
  }
}

// Topics for NaviDocs
const TOPICS = {
  WARRANTY_EXPIRING: 'warranty.expiring',
  DOCUMENT_UPLOADED: 'document.uploaded',
  SALE_INITIATED: 'sale.initiated',
  BOAT_TRANSFERRED: 'boat.transferred'
};

Webhook Framework

// server/services/webhook.service.js
class WebhookService {
  async sendWebhook(url, event) {
    // POST event to external system
    // Retry on failure (exponential backoff)
    // Log delivery status
  }

  async registerWebhook(organizationId, url, topics) {
    // Store webhook subscription
    // Validate URL reachability
  }
}

Structure:

# Session 2 Handoff to Session 3

## Mission Accomplished
- [x] Architecture designed
- [x] Sprint plan created
- [x] Code templates generated
- [x] Security audit complete

## Key Findings for Session 3 (UX/Sales)
1. Warranty tracking saves €8K-€33K per yacht (ROI calculator input)
2. Home Assistant integration enables remote monitoring
3. 4-week implementation timeline (Week 1: Foundation, Week 4: Deploy)
4. Security fixes required before demo (DELETE endpoint, auth)

## Blockers for Next Session
- [ ] Need UI/UX mockups for warranty dashboard (Session 3)
- [ ] Sales pitch requires demo script (Session 3)

## Token Consumption
- Total: 62,800 tokens ($1.42)
- Sonnet: 9,500 tokens
- Haiku: 53,300 tokens
- Efficiency: 68% Haiku delegation ✅

## Evidence Quality
- Code templates: 6 files created
- API endpoints: 15 new routes documented
- Migrations: 4 SQL scripts ready
- All architecture verified against NaviDocs codebase

## Next Session Input
Read: session-2-architecture.md, session-2-sprint-plan.md
Focus: Sales pitch, demo script, ROI calculator, objection handling
