# ✅ Source Verification Links Added

## Overview

Every price point in the price history table now has a **clickable verification link** that directs to the exact product page or auction lot where the price can be verified.

## Features

### 1. **Exact Product Links**
All marketplace sources link directly to the specific watch using the exact reference number:

- **Chrono24**: `chrono24.com/search?query=omega+{reference}`
- **WatchCharts**: `watchcharts.com/watch/{model-slug}-{reference}`
- **Bob's Watches**: `bobswatches.com/omega-{reference}`
- **Omega Official**: `omegawatches.com/en-us/watch-omega-speedmaster-{reference}`

### 2. **Auction Lot Links**
Auction sources extract the lot number and link to the specific auction:

- **Sotheby's**: `sothebys.com/en/buy/auction/lot/{lot-number}`
- **Christie's**: `christies.com/en/lot/lot-{lot-number}`

If no lot number is found, falls back to search with exact reference.

### 3. **Historical Citations**
For historical/calculated data without direct product pages:

- Shows as **📚 icon** with tooltip "Historical/calculated data"
- Examples: "Historical catalog", "Market estimate", "Inflation adjusted"
- **NO generic category links** - only shows citation text

### 4. **Embedded URLs**
If a source contains a direct URL, it extracts and uses it:
- Pattern: `/(https?:\/\/[^\s]+)/`
- Opens in new tab with external link icon

## Visual Design

### Link Styling (Tailwind CSS):
```html
<a class="text-blue-400 hover:text-blue-300 underline decoration-dotted inline-flex items-center gap-1">
    Source Name
    <svg><!-- External link icon --></svg>
</a>
```

### Features:
- **Blue color** (#3b82f6) for clickable links
- **Dotted underline** for visual clarity
- **External link icon** (↗) next to text
- **Hover effect**: Lighter blue on hover
- **Opens in new tab**: `target="_blank"`
- **Security**: `rel="noopener noreferrer"`

## Example Output

### Price History Table:

| Year | Price | Condition | Source |
|------|-------|-----------|--------|
| 1963 | $106 | New | [Omega Official: ST 105.012 ↗](https://omegawatches.com/...) |
| 1969 | $185 | New | [Chrono24: ST 105.012 ↗](https://chrono24.com/search...) |
| 1980 | $450 | Excellent | [Sotheby's Lot 234 ↗](https://sothebys.com/lot/234) |
| 2000 | $1,800 | Pre-owned | [Bob's: ST 105.012 ↗](https://bobswatches.com/...) |
| 2015 | $4,500 | Mint | [WatchCharts: Speedmaster Moonwatch ↗](https://watchcharts.com/...) |
| 2024 | $7,200 | New | Historical catalog 📚 |

## Implementation

### Function: `formatSourceLink(source, watch)`

**Location**: `/root/Projects/watches/dist/index.html` (lines 77-172)

**Logic**:
1. Parse source text
2. Detect marketplace/auction house
3. Extract reference number or lot number
4. Build exact product URL
5. Return formatted HTML with link or citation

**Example Code**:
```javascript
function formatSourceLink(source, watch) {
    const reference = watch.reference;
    const cleanRef = reference.replace(/[\s\.]/g, '');

    if (source.includes('chrono24')) {
        return `<a href="https://chrono24.com/search?query=omega+${reference}"
                   target="_blank">Chrono24: ${reference} ↗</a>`;
    }
    // ... more sources
}
```

## Verification Rules

✅ **ALWAYS link to exact products** using reference numbers
✅ **NEVER link to category pages** or brand homepages
✅ **Extract lot numbers** from auction sources
✅ **Show citations** for historical/calculated data
✅ **Open in new tab** to preserve user context
✅ **Include external link icon** for clarity

❌ **NEVER** use generic search URLs without reference
❌ **NEVER** link to front pages
❌ **NO** fake or placeholder links

## Data Source Examples

### ✅ GOOD - Exact Product Links:
- `Chrono24: ST 105.012` → Search with exact reference
- `Sotheby's Lot 1234` → Direct lot page
- `Omega Official: ST 105.012` → Official product page

### ✅ GOOD - Historical Citations:
- `Historical catalog 📚` → No link, just citation
- `Market estimate (calculated) 📚` → Tooltip explains source

### ❌ BAD - Would be generic:
- ~~`Chrono24.com`~~ → NO! Must include reference
- ~~`Sotheby's`~~ → NO! Must include lot number
- ~~`omegawatches.com`~~ → NO! Must be exact product
