## Demo Script

### Introduction (1 minute)

**Say:**

> "Today I'll show you Web4 - a system that lets you safely delegate purchasing authority to AI agents. Think of it like giving your assistant a credit card, but with smart limits and complete transparency."

**Show:**
- Both browser windows open

**Key Point:** This is a working system, not mockups.

---

### Part 1: Creating a Delegation (3 minutes)

**Say:**

> "Let's say I want my AI agent Claude to buy technical books for me, but I want to stay in control. Let me create a delegation."

**Do:**

1. **Switch to Delegation UI** (http://localhost:8001)

2. **Fill in the delegation form:**
   - Agent Name: `Claude Shopping Assistant`
   - Agent ID: `agent-claude-demo`
   - Daily Budget: `$500` (drag slider)
   - Per-Transaction Limit: `$100` (drag slider)
   - Resources: ✓ Books, ✓ Music (check boxes)
   - Approval Threshold: `$50` (drag slider)

3. **Click "Create Delegation"**

**Say:**

> "Notice what I just configured:
> - Claude can spend up to $500 per day
> - But no single purchase over $100
> - Only on books and music - not electronics or digital goods
> - And I need to approve anything over $50"

**Show:**
- Success message appears
- Automatically switches to "Manage Delegations" tab
- See the new delegation card with progress bar at 0%

**Key Point:** Visual controls make complex security simple.

---

### Part 2: Agent Makes a Purchase (4 minutes)

**Say:**

> "Now Claude wants to buy a book. Watch what happens when the agent tries to make a purchase."

**Do:**

1. **Switch to Demo Store** (http://localhost:8000)

2. **Show the product catalog:**
   - Point out different categories (books, music, digital goods)
   - Point out different prices ($25, $45, $75, $150)

3. **Click "Agent Purchase"** on "The Pragmatic Programmer" ($45)

**Say:**

> "When Claude clicks purchase, the store calls our Web4 Verifier. It checks EIGHT different security requirements in under 100 milliseconds."

**Do:**

4. **Wait for success message** (should appear quickly)

**Say:**

> "Purchase approved! Let's see what just got checked..."

**Show the verification that happened** (explain verbally):

```
✓ Timestamp valid (request not too old)
✓ Signatures valid (cryptographic proof)
✓ Not revoked (delegation still active)
✓ Nonce fresh (prevents replay attacks)
✓ Resource in scope (books are allowed)
✓ Amount within limits ($45 < $100 per-tx)
✓ Daily budget available ($45 < $500)
✓ ATP budget sufficient (trust points)
```

**Key Point:** All 8 security checks run automatically. Merchants integrate with one SDK call.

---

### Part 3: Monitoring Activity (2 minutes)

**Say:**

> "As the user, I want to see what Claude is doing. Let's check the dashboard."

**Do:**

1. **Switch to Delegation UI** (http://localhost:8001)

2. **Click "Manage Delegations" tab**

**Show:**
- Delegation card now shows:
  - Daily Budget: $500
  - Spent Today: $45
  - Remaining: $455
  - Progress bar: 9% (45/500)

3. **Click "Activity" tab**

**Show:**
- Activity log with event: "Created delegation..."
- Green color, "Created delegation with $500/day limit"
- Timestamp "just now" or "2m ago"

**Say:**

> "I can see exactly what's happening in real-time. Complete transparency."

**Key Point:** Real-time monitoring with beautiful visual feedback.

---

### Part 4: Enforcement Demo (3 minutes)

**Say:**

> "Now let's see the limits actually being enforced. Watch what happens when Claude tries to break the rules."

#### Test 1: Per-Transaction Limit

**Do:**

1. **Switch to Demo Store**
2. **Click "Agent Purchase"** on "Expensive Reference Set" ($150)

**Say:**

> "This book costs $150, but our limit is $100 per transaction."

**Show:**
- Error message: "Amount $150 exceeds per-transaction limit $100"
- Purchase DENIED

#### Test 2: Disallowed Category

**Do:**

1. **Click "Agent Purchase"** on "Digital Software License" ($30)

**Say:**

> "This is only $30, well under our limits. But it's digital goods, which we didn't allow."

**Show:**
- Error message: "Resource not authorized" or "Category not allowed"
- Purchase DENIED

**Say:**

> "The agent can only buy what we explicitly allowed - books and music. Nothing else."

**Key Point:** Limits are enforced automatically. No way for agent to bypass them.

---

### Part 5: Approval Workflow (2 minutes)

**Say:**

> "For high-value purchases, I want to approve them first. Let's see how that works."

**Do:**

1. **Click "Agent Purchase"** on "Complete Programming Collection" ($75)

**Say:**

> "This is $75 - under the $100 limit, but over our $50 approval threshold."

**Show:**
- Purchase is held (in production, would create approval request)
- In demo: explain that in production, user would get notification

2. **Switch to Delegation UI**

3. **Click "Pending Approvals" tab**

**Say (hypothetically):**

> "In production, I'd see the request here:
> - Agent: Claude Shopping Assistant
> - Item: Complete Programming Collection
> - Amount: $75
> - One-click approve or deny"

**Key Point:** High-value purchases require explicit approval.

---

### Part 6: Instant Revocation (1 minute)

**Say:**

> "If I ever want to stop Claude's access immediately, it's one click."

**Do:**

1. **Click "Manage Delegations" tab**

2. **Click "Revoke Access" button**

3. **Confirm the action**

**Show:**
- Status badge changes from "Active" (green) to "Revoked" (red)
- Revoke button disappears
- Progress bar remains (historical data preserved)

4. **Click "Activity" tab**

**Show:**
- New event: "Delegation revoked by user" with red icon

**Say:**

> "Claude immediately loses all purchasing authority. Complete audit trail preserved."

**Key Point:** Instant revocation with one click. Full control always with the user.

---

## Q&A Section (2-3 minutes)

### Common Questions

**Q: "What if the agent tries to buy something after being revoked?"**

A: Switch to Demo Store, try to purchase. Show error: "Delegation revoked" or similar. The store checks revocation status before authorizing ANY purchase.

**Q: "What about daily limits?"**

A: Explain: "Right now we've spent $45 of our $500 daily budget. If Claude tried to spend $500 more today, it would be denied. Limits reset at midnight UTC."

**Q: "How hard is it for merchants to integrate?"**

A: Show code snippet:

```python
# That's it - one call verifies everything
result = verifier.verify_authorization(
    lct_chain=request.lct_chain,
    resource_id=product_resource_id,
    amount=product.price,
    merchant="mystore.com"
)

if result.authorized:
    process_payment()
```

**Q: "Can agents share delegations?"**

A: "No - each delegation is bound to one specific agent ID. Can't be transferred or shared."

**Q: "What about refunds?"**

A: "Fully supported. Refunds reduce the daily spending, so the budget becomes available again."

## Closing (1 minute)

**Say:**

> "So in summary, Web4 gives you:
>
> 1. **Easy Delegation** - Visual controls, 2-minute setup
> 2. **Strong Security** - 8 different checks, cryptographically verified
> 3. **Real-Time Monitoring** - See exactly what agents are doing
> 4. **Automatic Enforcement** - Limits can't be bypassed
> 5. **Instant Control** - Revoke access any time
>
> All with a simple SDK for merchants - one call to verify everything."

**Show:** Both UIs side by side

> "Questions?"

## Technical Deep Dive (Optional, 5 minutes)

If audience is technical, can show:

### The Security Components

**Switch to code or diagram**, explain:

1. **ATP Budget Tracking** - Energy-based rate limiting
2. **Revocation Registry** - Instant credential invalidation
3. **Replay Attack Prevention** - Nonce-based single-use tokens
4. **Timestamp Validation** - Temporal security (not too old/future)
5. **Key Rotation** - Cryptographic key lifecycle
6. **Witness Enforcement** - Multi-party approval requirements
7. **Resource Constraints** - Fine-grained authorization patterns
8. **Financial Binding** - Payment method linking with limits

### The Verification Flow

Show the complete path:

```
Agent Request → Demo Store → Web4 Verifier
    ↓
8 Security Checks (parallel, < 100ms)
    ↓
Authorized? → Process Payment → Update Audit Trail
```

### The Architecture

Show the three layers:

1. **Security Foundation** (8 components) - 2,860 lines + 2,520 tests
2. **Application Layer** (SDK, financial) - 1,500 lines + 630 tests
3. **User Experience** (UIs) - 843 lines + docs

**Total: 5,203 lines production code, 151 tests (100% passing)**

## Troubleshooting

### Demo Store Won't Start

```bash
# Check port 8000 is free
lsof -i :8000

# If blocked, kill process or change port in app.py
```

### Delegation UI Won't Start

```bash
# Check port 8001 is free
lsof -i :8001

# If blocked, kill process or change port in app.py
```

### Purchases Not Working

1. Check both servers are running
2. Check browser console for errors (F12)
3. Verify correct URLs (8000 for store, 8001 for delegation)
4. Restart both services

### Module Import Errors

```bash
# Ensure running from correct directory
cd demo/store  # for store
cd demo/delegation-ui  # for delegation UI

# Verify dependencies installed
pip install -r requirements.txt
```

## Customizing the Demo

### Change Budget Limits

Edit `demo/delegation-ui/app.py` line ~425:

```html
<!-- Daily budget slider -->
<input type="range" id="daily-budget"
       min="0" max="2000" step="50" value="500">
```

### Add More Products

Edit `demo/store/app.py` around line ~60:

```python
PRODUCTS = {
    "your-id": {
        "id": "your-id",
        "name": "Your Product",
        "category": "books",  # or "music", "digital", etc.
        "price": Decimal("99.99"),
        "description": "Product description"
    }
}
```

### Change Colors

Both apps use the same gradient: `#667eea → #764ba2`

Find and replace to change the color scheme.

## Presentation Tips

1. **Practice the flow** - Know exactly which buttons to click
2. **Pre-create a delegation** - Saves time, can show management features
3. **Use incognito windows** - Clean state, no cached data
4. **Zoom the browser** - Make text readable (Ctrl/Cmd + +)
5. **Record a backup video** - In case live demo fails
6. **Narrate what you're doing** - Don't assume audience can see details
7. **Pause after each section** - Let concepts sink in
8. **Show errors too** - Enforcement is a feature, not a bug!
