5b6f452b09 fix: Prevent storage listener from clearing auth during login 
The storage event was firing when user was saved to localStorage,
causing loadStoredUser() to run and clear the auth state.

Added isLoginInProgress guard to skip storage events during login.

24d5625d17 fix: Include configured API host in allowed hosts for auth interceptor 
Token was not being attached to requests on VM deployments because
the IP address wasn't in the hardcoded allowedHosts list.

Now dynamically adds the host from RuntimeConfigService.apiBaseUrl
to the allowed list, fixing 401 errors on remote deployments.

## 🔄 Reverse Proxy Setup
### Nginx Reverse Proxy
```nginx
# /etc/nginx/sites-available/goa-gel-docs
upstream docs_backend {
server localhost:8080;
}
server {
listen 80;
server_name docs.goa-gel.gov.in;
location / {
proxy_pass http://docs_backend;

# Expected:
# CPU: < 1% idle, < 10% under load
# Memory: ~20-50MB
```
### Logs
```bash
# View logs
docker logs -f goa-gel-docs
# Last 100 lines
docker logs --tail 100 goa-gel-docs
# Logs since timestamp
docker logs --since 2024-01-01T00:00:00 goa-gel-docs
```
---
## 🔧 Troubleshooting
### Service Won't Start
```bash
# Check if port is in use
lsof -i :8080
# Check Docker logs
docker logs goa-gel-docs
# Try different port
docker run -d -p 9090:80 --name goa-gel-docs goa-gel-docs
```
### High Memory Usage
```bash
# Set memory limit
docker update --memory="256m" goa-gel-docs
# Or recreate with limit
docker stop goa-gel-docs
docker rm goa-gel-docs
docker run -d \
-p 8080:80 \
--memory="256m" \
--name goa-gel-docs \
goa-gel-docs
```
### Slow Performance
```bash
# Check resource usage
docker stats goa-gel-docs
# Increase CPU allocation
docker update --cpus="1.0" goa-gel-docs
# Enable gzip compression (already enabled in nginx.conf)
# Check if compression is working
curl -H "Accept-Encoding: gzip" -I http://localhost:8080/
# Should see: Content-Encoding: gzip
```
---
## 🔄 Updates
### Update Documentation Content
```bash
# Update markdown files in docs/
# Then rebuild and redeploy
docker build -t goa-gel-docs:1.0.1 .
docker stop goa-gel-docs
docker rm goa-gel-docs
docker run -d -p 8080:80 --name goa-gel-docs goa-gel-docs:1.0.1
```
### Zero-Downtime Update (with 2+ instances)
```bash
# Build new version
docker build -t goa-gel-docs:1.0.1 .
# Start new container on different port
docker run -d -p 8081:80 --name goa-gel-docs-new goa-gel-docs:1.0.1
# Test new version
curl http://localhost:8081/
# Update load balancer to point to 8081
# Then stop old container
docker stop goa-gel-docs
docker rm goa-gel-docs
# Rename new container
docker rename goa-gel-docs-new goa-gel-docs
```
---
## 🔐 Security Best Practices
### 1. Run as Non-Root User
Update Dockerfile:
```dockerfile
# Add after FROM nginx:alpine
RUN adduser -D -u 1000 docsuser
USER docsuser
```
### 2. Read-Only Filesystem
```bash
docker run -d \
-p 8080:80 \
--read-only \
--tmpfs /tmp \
--tmpfs /var/run \
--tmpfs /var/cache/nginx \
--name goa-gel-docs \
goa-gel-docs
```
### 3. Network Isolation
```bash
# Create isolated network
docker network create goa-gel-network
# Run with network
docker run -d \
-p 8080:80 \
--network goa-gel-network \
--name goa-gel-docs \
goa-gel-docs
```
### 4. Security Scanning
```bash
# Scan image for vulnerabilities
docker scan goa-gel-docs
# Or use Trivy
trivy image goa-gel-docs
```
---
## 📈 Performance Optimization
### CDN Setup
Use a CDN like Cloudflare for static assets:
1. Point domain to Cloudflare
2. Enable caching for:
- `/css/*`
- `/js/*`
- `/docs/*`
3. Enable Brotli compression
4. Enable HTTP/3
### Caching Headers
Already configured in `nginx.conf`:
```nginx
location ~* \.(jpg|jpeg|png|gif|ico|css|js|svg|woff|woff2|ttf|eot)$ {
expires 1y;
add_header Cache-Control "public, immutable";
}
```
---
## 🧪 Testing Deployment
```bash
# 1. Test homepage
curl -I http://localhost:8080/
# Expected: 200 OK
# 2. Test viewer
curl -I http://localhost:8080/viewer.html
# Expected: 200 OK
# 3. Test documentation
curl http://localhost:8080/docs/USER_GUIDE.md
# Expected: Markdown content
# 4. Test 404 handling
curl -I http://localhost:8080/nonexistent
# Expected: 404 Not Found
# 5. Load test (requires Apache Bench)
ab -n 1000 -c 10 http://localhost:8080/
# Should handle 1000 requests easily
```

# Find what's using port 8080
lsof -i :8080
# Kill the process (replace PID with actual PID)
kill -9 PID
```
### Docker Build Fails
**Check Docker is Running**
```bash
docker --version
docker ps
# If not running, start Docker Desktop
```
**Clear Docker Cache**
```bash
docker system prune -a
docker build --no-cache -t goa-gel-docs .
```
### Documentation Not Loading
**Check files exist**
```bash
ls -la docs/
# Should see all .md files
ls -la public/
# Should see index.html, viewer.html, css/, js/
```
**Check container logs**
```bash
docker logs goa-gel-docs
# Look for any error messages
```
### Blank Page or 404 Errors
**Clear Browser Cache**
- Press Ctrl+Shift+R (Windows/Linux)
- Press Cmd+Shift+R (Mac)
- Or use Incognito/Private mode
**Check network tab**
- Open browser DevTools (F12)
- Go to Network tab
- Refresh page
- Look for failed requests (red)
---
## 📱 Access from Mobile
### Same Network
1. Find your computer's IP address:
```bash
# Mac/Linux
ifconfig | grep "inet "
# Windows
ipconfig
```
2. On mobile, open browser and go to:
```
http://YOUR_IP_ADDRESS:8080
```
### Public Access (Advanced)
Use a reverse proxy or cloud hosting (see DEPLOY.md for details)
---
## 🔄 Updating Documentation
### Update Markdown Files
1. Edit `.md` files in `docs/` directory
2. Rebuild and restart:
**Docker:**
```bash
docker build -t goa-gel-docs .
docker stop goa-gel-docs && docker rm goa-gel-docs
docker run -d -p 8080:80 --name goa-gel-docs goa-gel-docs
```
**Local:**
```bash
# No rebuild needed - just refresh browser
# Server automatically serves updated files
```
### Add New Documentation
1. Add new `.md` file to `docs/` directory
2. Update `public/js/viewer.js` - add to `DOC_MAP`:
```javascript
const DOC_MAP = {
'YOUR_NEW_DOC': '/docs/YOUR_NEW_DOC.md',
// ... existing entries
};
```
3. Rebuild and restart (if using Docker)

## 🐛 Troubleshooting
### Issue: Documentation not loading
**Symptom**: Blank page or "Document not found" error
**Solution**:
1. Check if Markdown files are in `/docs` directory
2. Verify `DOC_MAP` in `viewer.js` is correct
3. Check browser console for errors
4. Clear browser cache
### Issue: Syntax highlighting not working
**Symptom**: Code blocks show plain text
**Solution**:
1. Check if highlight.js is loading (check network tab)
2. Verify CDN links are accessible
3. Check for JavaScript errors in console
### Issue: Container not starting
**Symptom**: `docker run` fails or exits immediately
**Solution**:
```bash
# Check Docker logs
docker logs goa-gel-docs
# Verify port is not in use
lsof -i :8080
# Try a different port
docker run -d -p 9090:80 --name goa-gel-docs goa-gel-docs
```
### Issue: Styles not applying
**Symptom**: Page looks unstyled
**Solution**:
1. Check if `/css/styles.css` exists
2. View page source and verify CSS link
3. Check browser Network tab for 404 errors
4. Clear browser cache

# Executive Summary
## The Challenge
Government licensing in Goa processes over 50,000 applications annually across 15+ departments. Current paper-based systems result in:
- 45-90 day average processing times
- Estimated 8-12% fraudulent documents in circulation
- No real-time tracking for citizens
- Incomplete audit trails leading to compliance gaps
- High staff overhead on administrative tasks
## The Solution
License Authority digitizes the complete license lifecycle:
1. **Online application** with DigiLocker integration
2. **Automated workflow** with configurable approval stages
3. **Blockchain-issued certificates** that cannot be forged
4. **Real-time tracking** for applicants and administrators
5. **Complete audit trail** for every transaction
## Expected Outcomes
| Metric | Target |
|--------|--------|
| Processing time reduction | 60% |
| Citizen portal adoption | 80%+ |
| Document fraud | Zero tolerance |
| Staff productivity gain | 40% |
| Audit compliance | 100% |
## Investment Summary
| Category | Description |
|----------|-------------|
| Platform License | Annual subscription per department |
| Implementation | One-time setup and configuration |
| Training | Staff onboarding program |
| Support | 24/7 technical assistance |
## Governance
- Department retains full control over workflow rules
- All data stored in government infrastructure
- Blockchain network operated by state IT department
- Regular compliance audits by designated authority

# Workflow Management
## Understanding Workflows
A workflow defines the approval stages an application passes through before license issuance. Department administrators configure workflows for each license type.
## Workflow Components
### Stages
Each stage represents a review step:
| Property | Description |
|----------|-------------|
| Name | Stage identifier (e.g., "Document Verification") |
| Order | Sequence position (1, 2, 3...) |
| Assignee Rule | Who receives applications at this stage |
| Required Actions | What must be completed to proceed |
| SLA | Maximum time allowed |
### Stage Types
**Sequential**: Applications must pass through in order
```
Stage 1 → Stage 2 → Stage 3 → Issuance
```
**Parallel**: Multiple reviews happen simultaneously
```
┌→ Technical Review ─┐
Stage 1 ─┤ ├→ Final Approval
└→ Financial Review ─┘
```
### Assignment Rules
- **Round Robin**: Distribute evenly across available officers
- **Load Based**: Assign to officer with fewest pending items
- **Manual**: Supervisor assigns each application
- **Specific Role**: Route to designated role
## Creating a Workflow
1. Navigate to **Settings** → **Workflows**
2. Click **Create New Workflow**
3. Enter workflow name and description
4. Add stages in sequence:
- Define stage name
- Set assignment rule
- Configure SLA duration
- Specify required documents
5. Set workflow as active
6. Assign to license type(s)
## Modifying Workflows
Changes apply only to new applications. In-progress applications continue with their original workflow.
To modify:
1. Open workflow in editor
2. Make changes
3. Review impact summary
4. Confirm and save
## SLA Configuration
| Field | Description |
|-------|-------------|
| Duration | Hours/days allowed |
| Warning | Alert before breach |
| Escalation | Action on breach |
| Override | Manual extension allowed |
## Best Practices
- Keep stages focused on single responsibility
- Set realistic SLAs based on actual processing time
- Use parallel stages for independent reviews
- Document stage requirements clearly
- Review workflow performance monthly

# Webhooks
## Overview
The platform sends webhook notifications for key events. Configure webhook endpoints to receive real-time updates.
## Configuration
Register webhook endpoint:
```http
POST /webhooks
Authorization: Bearer <token>
{
"url": "https://your-system.com/webhook",
"events": ["application.approved", "certificate.issued"],
"secret": "your-webhook-secret"
}
```
## Event Types
| Event | Trigger |
|-------|---------|
| `application.submitted` | New application received |
| `application.approved` | Application approved |
| `application.rejected` | Application rejected |
| `application.returned` | Returned for corrections |
| `certificate.issued` | License NFT minted |
| `certificate.revoked` | License revoked |
## Payload Format
```json
{
"event": "application.approved",
"timestamp": "2026-02-09T10:00:00Z",
"data": {
"applicationId": "APP-2026-00001",
"licenseType": "TRADE_LICENSE",
"applicantId": "DL-12345678"
}
}
```
## Signature Verification
Verify webhook authenticity using HMAC-SHA256:
```javascript
const crypto = require('crypto');
function verifySignature(payload, signature, secret) {
const expected = crypto
.createHmac('sha256', secret)
.update(payload)
.digest('hex');
return crypto.timingSafeEqual(
Buffer.from(signature),
Buffer.from(expected)
);
}
```
Header: `X-Webhook-Signature: sha256=<signature>`
## Retry Policy
Failed deliveries (non-2xx response) are retried:
- 1st retry: 1 minute
- 2nd retry: 5 minutes
- 3rd retry: 30 minutes
- 4th retry: 2 hours
- 5th retry: 24 hours
After 5 failures, webhook is disabled. Re-enable via API.

└─> SHA-256 hash of each document
3. Blockchain Recording
└─> Hash recorded on Besu (QBFT consensus)
4. Route to Departments
└─> Tourism + Fire Safety (parallel)
5-6. Departments Receive Notifications
└─> Ready for review
7-8. Departments Approve (Parallel)
└─> Record approvals on blockchain
9. NFT Minting
└─> ERC-721 Soulbound license certificate
10. Notifications Sent
└─> Citizen receives approval
11. Verification
└─> Anyone can verify on blockchain
```
---
## ⛓️ Blockchain Details
### Consensus
- **Type**: QBFT (Quorum Byzantine Fault Tolerant)
- **Validators**: 4 nodes
- **Requirement**: 3/4 (75%) agreement
- **Block Time**: ~12 seconds
- **Network**: Private permissioned
### Smart Contracts (4)
| Contract | Purpose | Key Functions |
|----------|---------|---|
| LicenseRequestNFT | Issue licenses as NFTs | mint(), burn(), ownerOf() |
| ApprovalManager | Record approvals | recordApproval(), getApprovalChain() |
| DepartmentRegistry | Manage departments | registerDept(), setApprovers() |
| WorkflowRegistry | Define workflows | defineWorkflow(), getWorkflow() |
### Data Strategy
**On-Chain** (Immutable & Verifiable):
- License hashes
- Approval signatures
- Department registry
- NFT ownership
**Off-Chain** (Searchable & Scalable):
- Full document details
- Applicant information
- Actual document files
- Workflow state
**Link**: SHA-256 hash bridges both worlds

# Platform Overview
License Authority is an enterprise platform that transforms government licensing operations through blockchain-based credential issuance and configurable workflow automation.
## Context
Government licensing processes across India handle millions of applications annually. These processes involve multiple stakeholders, complex approval hierarchies, and strict compliance requirements. Traditional systems face persistent challenges that impact both operational efficiency and citizen trust.
The platform addresses these challenges through a purpose-built platform that combines workflow automation with cryptographic verification.
## Platform Objectives
| Objective | Measurement |
|-----------|-------------|
| Eliminate document fraud | Zero forged licenses in circulation |
| Reduce processing time | 60% reduction in average approval duration |
| Ensure complete traceability | 100% audit coverage for all transactions |
| Enable citizen self-service | 80% of status inquiries handled without staff |
| Support multi-department deployment | Single platform serving 15+ departments |
## Core Capabilities
### Tokenized License Certificates
Every license issued through the platform is minted as a Non-Fungible Token (NFT) on a private Hyperledger Besu blockchain. This provides:
- **Cryptographic authenticity**: Certificates are digitally signed and verifiable
- **Tamper evidence**: Any modification attempt is detectable
- **Instant verification**: QR code scanning validates certificate authenticity
- **Permanent record**: Blockchain maintains immutable issuance history
### Configurable Workflow Engine
Departments define their approval processes through a visual workflow builder:
- Sequential and parallel approval stages
- Conditional routing based on application attributes
- Automated document validation rules
- SLA tracking with escalation triggers
- Role-based task assignment
### Unified Operations Dashboard
Administrators and department heads access real-time visibility into:
- Application volumes and processing rates
- Stage-wise bottleneck identification
- SLA compliance metrics
- Staff workload distribution
- Revenue and fee collection status
## Deployment Model
The platform operates as a multi-tenant platform with department-level isolation:
```

│ License Authority │
├─────────────────────────────────┤
┌───────────┼───────────┬───────────┐ │
│ │ │ │ │
┌────▼────┐ ┌────▼────┐ ┌────▼────┐ ┌────▼────┐ │

│ │
│ Shared Infrastructure │
│ - Blockchain Network │
│ - Authentication Service │
│ - Notification Gateway │
│ - Analytics Engine │
└─────────────────────────────────┘
```
## Integration Points
The platform integrates with government and third-party services:
| Integration | Purpose | Protocol |
|-------------|---------|----------|
| DigiLocker | Citizen identity verification, document retrieval | OAuth 2.0 |
| Payment Gateway | License fee collection | REST API |
| SMS Gateway | Application status notifications | HTTP |
| Email Service | Formal communications and certificates | SMTP |
| Legacy Systems | Data migration, reference data sync | Batch/API |
## User Roles
| Role | Responsibilities |
|------|------------------|
| **Applicant** | Submit applications, upload documents, track status, download certificates |
| **Department Officer** | Review applications, verify documents, approve/reject/return |
| **Department Admin** | Configure workflows, manage staff, view department analytics |
| **System Administrator** | Manage departments, monitor platform health, handle escalations |

# Problem Statement
## Current State Challenges
### Document Fraud
Paper-based licenses are routinely forged. Verification requires manual cross-checking with issuing authorities, which is slow and unreliable. Forged documents circulate undetected for years.
### Process Opacity
Applicants have no visibility into application status. Inquiries require office visits or phone calls. Staff cannot explain delays because tracking is fragmented across manual registers.
### Inconsistent Processing
Same license type processed differently across offices. No standardized workflows. Processing time varies from days to months depending on which officer handles the case.
### Lost Audit Trail
Paper files get misplaced. Handover between officers leaves no record. When disputes arise, reconstructing decision history is impossible.
### Manual Bottlenecks
Every approval requires physical file movement. Officers juggle hundreds of pending files. Urgent applications have no priority mechanism.
## Quantified Impact
| Metric | Current State |
|--------|---------------|
| Average processing time | 45-90 days |
| Fraudulent documents in circulation | Estimated 8-12% |
| Applicant inquiries requiring staff time | 60% of applications |
| Applications with incomplete audit trail | 40%+ |
| Staff time on file management vs. review | 50% overhead |
## Requirements for Solution
1. **Tamper-proof certificates** that can be verified instantly without contacting the issuing office
2. **Real-time status tracking** accessible to applicants through self-service portal
3. **Standardized workflows** enforced by the system, not dependent on individual officers
4. **Complete audit trail** automatically captured for every action
5. **Digital-first processing** eliminating physical file movement

## Configuration
## Diagram Contents
### Local Development
### 1. system-context.mermaid
**C4 Level 1 Context Diagram**
- Shows the GEL platform as a black box
- External actors: Citizens, Government Departments, Department Operators, Platform Operators
- External systems: DigiLocker Mock, Legacy Department Systems, National Blockchain Federation (future)
No configuration needed - just run `docker-compose up -d`.
### 2. container-architecture.mermaid
**C4 Level 2 Container Diagram**
- Frontend: Next.js 14 with shadcn/ui (Port 3000)
- Backend: NestJS API Gateway (Port 3001)
- Database: PostgreSQL (Port 5432)
- Cache: Redis (Port 6379)
- Storage: MinIO S3-compatible (Port 9000)
- Blockchain: Hyperledger Besu nodes
- Services: Auth, Workflow, Approval, Document
### Remote Deployment (VM/Kubernetes)
### 3. blockchain-architecture.mermaid
**Blockchain Layer Deep Dive**
- 4 Hyperledger Besu Validator Nodes (QBFT Consensus)
- RPC Ports: 8545-8548
- Smart Contracts:
- LicenseRequestNFT (ERC-721 Soulbound)
- ApprovalManager
- DepartmentRegistry
- WorkflowRegistry
- On-Chain vs Off-Chain Data Split
- Content Hashing (SHA-256) for Immutable Links
Create a `.env` file from the template:
### 4. workflow-state-machine.mermaid
**License Request Workflow States**
States:
- DRAFT: Initial local draft
- SUBMITTED: Hash recorded on blockchain
- IN_REVIEW: Multi-department approval
- PENDING_RESUBMISSION: Changes requested
- APPROVED: License granted, NFT minted
- REJECTED: Request denied
- REVOKED: License cancelled
```bash
cp .env.example .env
```
### 5. data-flow.mermaid
**Complete End-to-End Sequence**
11-Step Process:
1. License Request Submission
2. Document Upload & Hashing
3. Blockchain Recording
4. State Update to SUBMITTED
5. Route to Department 1 (Tourism)
6. Route to Department 2 (Fire Safety) - Parallel
7. Department 1 Approval
8. Department 2 Approval - Parallel
9. Final Approval Processing
10. Update Final State & Notifications
11. License Verification
Configure external access URLs:
### 6. deployment-architecture.mermaid
**Docker Compose Deployment**
Services:
- Frontend: Next.js (Port 3000)
- Backend: NestJS (Port 3001)
- Database: PostgreSQL (Port 5432)
- Cache: Redis (Port 6379)
- Storage: MinIO (Port 9000, 9001)
- Blockchain: 4x Besu Validators (Ports 8545-8548)
- Monitoring: Prometheus (9090), Grafana (3000 alt)
```env
# Public URL where browsers access the API
API_BASE_URL=http://your-server-ip:3001/api/v1
Volumes & Configuration Files
# Frontend URL for CORS
CORS_ORIGIN=http://your-server-ip:4200
```
## Key Technical Decisions
### Production
### Blockchain
- **Platform:** Hyperledger Besu
- **Consensus:** QBFT (Quorum Byzantine Fault Tolerant)
- **Network Type:** Private Permissioned
- **Validators:** 4 nodes (requires 3/4 approval)
- **Block Time:** ~12 seconds
Update security credentials in `.env`:
### Tokens
- **Standard:** ERC-721
- **Type:** Soulbound NFTs
- **Purpose:** Non-transferable license certificates
- **Metadata:** Immutable license details
```env
# Generate with: openssl rand -base64 32
JWT_SECRET=your-secure-jwt-secret-min-32-chars
# Strong passwords
DATABASE_PASSWORD=your-secure-db-password
MINIO_ACCESS_KEY=your-minio-access-key
MINIO_SECRET_KEY=your-minio-secret-key
```
## Development
### Backend
- **Framework:** NestJS (TypeScript)
- **Database:** PostgreSQL
- **File Storage:** MinIO (S3-compatible)
- **Cache:** Redis
```bash
cd backend
npm install
npm run start:dev # Development with hot reload
npm run test # Run tests
npm run db:migrate # Run migrations
npm run db:seed # Seed database
```
### Frontend
- **Framework:** Next.js 14
- **UI:** shadcn/ui
- **State Management:** React Context/TanStack Query
- **Styling:** Tailwind CSS
### Authentication
- **POC Phase:** API Key + Secret
- **Future:** DigiLocker Integration (Mocked)
## Architecture Benefits
1. **Immutable Records**: Blockchain ensures license records cannot be tampered with
2. **Multi-Department Workflows**: Parallel or sequential approvals based on license type
3. **Transparent Verification**: Anyone can verify license authenticity on blockchain
4. **Scalability**: Off-chain document storage with on-chain hashing
5. **Auditability**: Complete audit trail of all state changes
6. **Privacy**: Permissioned network with department access controls
7. **Future-Proof**: NFT standard enables future interoperability
## Viewing Instructions
1. **Mermaid Live** (Easiest): https://mermaid.live
- Copy-paste content from .mermaid files
- Instant preview and export
2. **HTML Files** (Built-in Browser):
- Open system-context.html (and others) in any web browser
- Uses CDN-hosted mermaid.js for rendering
3. **PNG Export**:
- Follow the conversion options above
- Recommended: Use mermaid-cli or online converter

## Next Steps
## API Documentation
1. Review all diagrams to understand system architecture
2. Use these for documentation and stakeholder presentations
3. Convert to PNG/SVG for inclusion in technical documentation
4. Share with team for feedback and refinement
API endpoints follow RESTful conventions at `/api/v1`:
| Endpoint | Description |
|----------|-------------|
| `/auth` | Authentication (login, register, refresh) |
| `/requests` | License applications CRUD |
| `/approvals` | Approval workflow actions |
| `/documents` | Document upload and management |
| `/workflows` | Workflow configuration |
| `/departments` | Department management |
| `/admin` | Platform administration |
Health check: `GET /api/v1/health`
## Blockchain
Smart contracts are automatically deployed on first startup:
- **LicenseNFT**: ERC-721 soulbound tokens for approved licenses
- **ApprovalManager**: Multi-signature approval tracking
- **DepartmentRegistry**: Department configuration on-chain
- **WorkflowRegistry**: Workflow definitions
Contract addresses are stored in `/app/.env` inside the API container.
