npm package: @iota-big3/nonprofit-config
Description: Nonprofit platform configuration using existing SDK packages
Latest version: 1.0.0

# Nonprofit Configuration Package

A **configuration-only** package that composes existing IOTA Big3 SDK packages to create a trustworthy nonprofit platform. Built on First Principles: Trust = Transparency + Security + Compliance.

## 🎯 Philosophy

This package follows the First Principles approach:

1. **Don't Duplicate** - We compose existing SDK packages rather than creating nonprofit-specific versions
2. **Immutable Events** - Every action is an append-only event for perfect audit trails
3. **Compliance First** - Security and regulatory compliance are foundational, not features
4. **Trust Over Speed** - We optimize for accuracy and transparency, not transaction volume

## 📦 Architecture

```
nonprofit-platform/
├── Event Store (sdk-events)         # Immutable audit trail
├── Compliance Engine (sdk-compliance)  # 501(c)(3) rules
├── Payment Processor (sdk-payment)     # Secure donations
├── Security Layer (sdk-security)       # Zero-trust architecture
└── Observability (sdk-observability)   # Real-time monitoring
```

## 🚀 Quick Start

```typescript
import {
  NonprofitEventStore,
  NonprofitPaymentHandler,
  NonprofitComplianceConfig,
} from "@iota-big3/nonprofit-config";

// Initialize with existing SDKs
const eventBus = new EventBus();
const paymentSDK = new PaymentProcessor({ provider: "stripe" });
const complianceSDK = new ComplianceSDK({ tenantId: "nonprofit-123" });

// Create nonprofit-specific configuration
const eventStore = new NonprofitEventStore(eventBus, auditLogger);
const paymentHandler = new NonprofitPaymentHandler(
  paymentSDK,
  complianceSDK,
  eventStore
);

// Process donation with full compliance
const result = await paymentHandler.processDonation({
  amount: 100,
  currency: "USD",
  donorId: "donor-123",
  donorEmail: "donor@example.com",
  taxDeductible: true,
});
```

## 📋 Implementation Phases

### Phase 1: Foundation (Weeks 1-4) ✅

- [x] Event-sourced architecture
- [x] Compliance rules engine
- [x] Immutable audit trail
- [x] Security configuration

### Phase 2: Payment Security (Weeks 5-8) 🚧

- [x] Payment handler with compliance
- [ ] Receipt generation
- [ ] Fraud detection
- [ ] Recurring donations

### Phase 3: Trust Features (Weeks 9-12) 📅

- [ ] Real-time transparency dashboard
- [ ] Public impact reporting
- [ ] Donor portal
- [ ] Automated compliance reports

## 🔒 Security & Compliance

### 501(c)(3) Requirements

- No political campaign activity
- No private benefit/inurement
- Tax receipts for donations > $250
- Quid pro quo disclosure > $75

### International Compliance

- GDPR for EU donors
- Canada Revenue Agency rules
- UK Charity Commission requirements

### Data Protection

- AES-256 encryption at rest
- TLS 1.3 in transit
- 90-day key rotation
- Role-based access control

## 📊 Event-Sourced Architecture

Every action creates an immutable event:

```typescript
// Traditional approach (mutable state) ❌
UPDATE donors SET total_donated = total_donated + 100;

// Event-sourced approach (immutable events) ✅
await eventStore.recordEvent({
  type: 'DONATION_RECEIVED',
  data: { donorId, amount: 100 },
  timestamp: new Date()
});
```

Benefits:

- Perfect audit trails for regulators
- Time-travel debugging
- Complete transaction history
- Impossible to lose data

## 🎯 Success Metrics

We measure trust, not volume:

| Metric            | Target | Why It Matters                |
| ----------------- | ------ | ----------------------------- |
| Compliance Score  | 100%   | Zero tolerance for violations |
| Receipt Accuracy  | 100%   | IRS requirements              |
| Audit Coverage    | 100%   | Every transaction traceable   |
| Security Breaches | 0      | Donor trust is paramount      |
| Processing Fees   | <2%    | More money to the cause       |

## ⚠️ What This Is NOT

- ❌ NOT a standalone payment processor
- ❌ NOT a complete nonprofit CRM
- ❌ NOT a frontend application
- ✅ Configuration layer for existing SDKs
- ✅ Compliance rules and workflows
- ✅ Trust-building architecture

## 🤝 Integration with Existing SDKs

| SDK Package    | Purpose      | How We Use It         |
| -------------- | ------------ | --------------------- |
| sdk-events     | Event bus    | Immutable audit trail |
| sdk-payment    | Payments     | Donation processing   |
| sdk-compliance | Rules engine | 501(c)(3) validation  |
| sdk-billing    | Invoicing    | Receipt generation    |
| sdk-security   | Security     | Encryption & access   |
| sdk-database   | Storage      | Event persistence     |

## 🚨 Critical Implementation Notes

1. **Never Update Events** - Events are immutable. Create new events for corrections.
2. **Compliance First** - Always validate compliance before processing payments.
3. **Fail Safe** - When in doubt, reject the transaction and request human review.
4. **Document Everything** - Every decision must have an audit trail.

**Remember**: For nonprofits, trust is everything. One compliance failure or security breach can destroy years of donor relationships. Build for trust, not speed.
