## 1️⃣ Sentry Error Monitoring

### What Was Implemented

- **Client-side error tracking** (`sentry.client.config.ts`)
- **Server-side error tracking** (`sentry.server.config.ts`)
- **Edge runtime support** (`sentry.edge.config.ts`)
- **ErrorBoundary integration** - Automatically captures React errors
- **Privacy-preserving configuration** - Filters sensitive data

### Files Added/Modified

```

├── sentry.client.config.ts    ✅ NEW
├── sentry.server.config.ts    ✅ NEW
├── sentry.edge.config.ts      ✅ NEW
├── components/ErrorBoundary.tsx  ✅ UPDATED (Sentry integration)
└── .env.example               ✅ Already had NEXT_PUBLIC_SENTRY_DSN
```

### How to Use

1. **Get Sentry DSN:**
   ```bash
   # Sign up at https://sentry.io
   # Create new project (Next.js)
   # Copy DSN
   ```

2. **Add to Environment:**
   ```bash
   # .env.local
   NEXT_PUBLIC_SENTRY_DSN=https://...@sentry.io/...
   ```

3. **Deploy:**
   - Sentry automatically captures errors in production
   - Disabled in development (won't spam during testing)
   - Privacy-preserving (filters cookies and sensitive data)

### Features

- ✅ Captures React component errors
- ✅ Captures unhandled promise rejections
- ✅ Session replays (10% of sessions, 100% of errors)
- ✅ Performance monitoring
- ✅ Ignores wallet-related errors (user rejections)
- ✅ Privacy-first (no sensitive data sent)

## 2️⃣ Test Suite

### What Was Implemented

- **Jest** - Testing framework
- **React Testing Library** - Component testing
- **Test configuration** - Optimized for Next.js

## 3️⃣ RISC Zero Integration Framework

### What Was Implemented

- **Production-ready architecture** for RISC Zero SDK
- **Mock implementation** for demo/testing
- **Clear migration path** to real ZK proofs
- **Type-safe interfaces** for proof generation
- **Comprehensive documentation** in code

### Files Added/Modified

```
base-mini-app/
├── lib/risc-zero.ts                      ✅ NEW (framework)
└── components/BeliefAttestationForm.tsx  ✅ UPDATED (uses framework)
```

### Architecture

```typescript
// Public API (production-ready)
interface BeliefProofInputs {
  belief: string;
  beliefHash: `0x${string}`;
  loyaltyScore: number;
  moduleId: number;
  activityProof: string;
  proverAddress: `0x${string}`;
}

interface ZKProof {
  proofBytes: `0x${string}`;
  publicInputs: bigint[];
}

// Main function (currently mock, ready for real implementation)
async function generateBeliefProof(inputs: BeliefProofInputs): Promise<ZKProof>
```

### Migration Path to Production

**Current State:** Mock implementation (deterministic, for testing)

**To Integrate Real RISC Zero:**

1. **Install RISC Zero SDK:**
   ```bash
   npm install @risc0/zkvm
   ```

2. **Create guest program** (Rust code running in zkVM):
   ```rust
   // methods/guest/src/main.rs
   use risc0_zkvm::guest::env;

   fn main() {
       // Read inputs (belief, loyalty score, threshold)
       let inputs: BeliefInputs = env::read();

       // Verify loyalty score >= threshold
       assert!(inputs.loyalty_score >= 80);

       // Verify belief hash matches
       let computed_hash = hash_belief(&inputs.belief);
       assert_eq!(computed_hash, inputs.belief_hash);

       // Commit public outputs (belief hash only)
       env::commit(&inputs.belief_hash);
   }
   ```

3. **Build guest program:**
   ```bash
   cargo risczero build
   ```

4. **Replace mock in `lib/risc-zero.ts`:**
   ```typescript
   import { createProof } from '@risc0/zkvm';
   import { BELIEF_VERIFIER_ID } from './methods';

   async function generateBeliefProof(inputs: BeliefProofInputs): Promise<ZKProof> {
     // Real implementation
     const proof = await createProof({
       guestId: BELIEF_VERIFIER_ID,
       inputs: serializeInputs(inputs),
     });

     return {
       proofBytes: proof.seal,
       publicInputs: proof.journal,
     };
   }
   ```

5. **Update contract addresses:**
   - Deploy BeliefAttestationVerifier
   - Redeploy DilithiumAttestor with `zkEnabled=true`

### Current Features

- ✅ Type-safe proof generation interface
- ✅ Mock implementation for testing
- ✅ Deterministic proofs (consistent outputs for same inputs)
- ✅ Integration with BeliefAttestationForm
- ✅ Conditional warning banner (shows only when using mocks)
- ✅ Proof system info utility functions

### Proof System Info

```typescript
getProofSystemInfo() => {
  name: 'RISC Zero STARK',
  version: 'Mock (Demo)' | 'Production',
  postQuantumSecure: true,
  trustedSetup: false,
  averageProofTime: 100ms (mock) | 2000-5000ms (real),
  estimatedGasCost: 61000 gas
}
```

   ```bash
   # Root .env
   PRIVATE_KEY=your_private_key_here
   BASESCAN_API_KEY=your_basescan_api_key  # Optional, for verification
   ```

3. **Deploy to Base Sepolia:**
   ```bash
