fix(preflight): Correct parameter order and add IP/fingerprint reporting

- Fix update_worker_preflight call to use correct parameter order:
  (worker_id, transport, status, ip, response_ms, error, fingerprint)
- Add proxyIp to both curl and http preflight reports
- Add fingerprint JSONB with timezone, location, and bot detection data
- Log HTTP IP and timezone after preflight completes

+## Common Mistakes to Avoid
+
+1. **Don't use `src/hydration/`** - It's an old approach that was superseded by the task system
+
+2. **Don't use `src/dutchie-az/db/connection.ts`** - Use `src/db/pool.ts` instead
+
+3. **Don't import `src/db/migrate.ts` at runtime** - It will crash. Only use for CLI migrations.
+
+4. **Don't query `stores` table** - It's empty. Use `dispensaries`.
+
+5. **Don't query `products` table** - It's empty. Use `store_products`.
+
+6. **Don't use wrong GraphQL hash** - Always get hash from `GRAPHQL_HASHES` in client.ts
+
+7. **Don't use `Status: null`** - It returns 0 products. Use `Status: 'Active'`.
+
+---
+
+## When in Doubt
+
+1. Check if the file is imported in `src/index.ts` - if not, it may be deprecated
+2. Check the last modified date - older files may be stale
+3. Look for `DEPRECATED` comments in the code
+4. Ask: "Is there a newer version of this in `src/tasks/` or `src/platforms/`?"
+5. Read the relevant doc in `docs/` before modifying code

+# Organic Browser-Based Scraping Guide
+
+**Last Updated:** 2025-12-12
+**Status:** Production-ready proof of concept
+
+---
+
+## Overview
+
+This document describes the "organic" browser-based approach to scraping Dutchie dispensary menus. Unlike direct curl/axios requests, this method uses a real browser session to make API calls, making requests appear natural and reducing detection risk.
+
+---
+
+## Why Organic Scraping?
+
+| Approach | Detection Risk | Speed | Complexity |
+|----------|---------------|-------|------------|
+| Direct curl | Higher | Fast | Low |
+| curl-impersonate | Medium | Fast | Medium |
+| **Browser-based (organic)** | **Lowest** | Slower | Higher |
+
+Direct curl requests can be fingerprinted via:
+- TLS fingerprint (cipher suites, extensions)
+- Header order and values
+- Missing cookies/session data
+- Request patterns
+
+Browser-based requests inherit:
+- Real Chrome TLS fingerprint
+- Session cookies from page visit
+- Natural header order
+- JavaScript execution environment
+
+---
+
+## Implementation
+
+### Dependencies
+
+```bash
+npm install puppeteer puppeteer-extra puppeteer-extra-plugin-stealth
+```
+
+### Core Script: `test-intercept.js`
+
+Located at: `backend/test-intercept.js`
+
+```javascript
+const puppeteer = require('puppeteer-extra');
+const StealthPlugin = require('puppeteer-extra-plugin-stealth');
+const fs = require('fs');
+
+puppeteer.use(StealthPlugin());
+
+async function capturePayload(config) {
+  const { dispensaryId, platformId, cName, outputPath } = config;
+
+  const browser = await puppeteer.launch({
+    headless: 'new',
+    args: ['--no-sandbox', '--disable-setuid-sandbox']
+  });
+
+  const page = await browser.newPage();
+
+  // STEP 1: Establish session by visiting the menu
+  const embedUrl = `https://dutchie.com/embedded-menu/${cName}?menuType=rec`;
+  await page.goto(embedUrl, { waitUntil: 'networkidle2', timeout: 60000 });
+
+  // STEP 2: Fetch ALL products using GraphQL from browser context
+  const result = await page.evaluate(async (platformId) => {
+    const allProducts = [];
+    let pageNum = 0;
+    const perPage = 100;
+    let totalCount = 0;
+    const sessionId = 'browser-session-' + Date.now();
+
+    while (pageNum < 30) {
+      const variables = {
+        includeEnterpriseSpecials: false,
+        productsFilter: {
+          dispensaryId: platformId,
+          pricingType: 'rec',

+        }
+      };
+
+      const qs = new URLSearchParams({
+        operationName: 'FilteredProducts',
+        variables: JSON.stringify(variables),
+        extensions: JSON.stringify(extensions)
+      });
+
+      const response = await fetch(`https://dutchie.com/api-3/graphql?${qs}`, {
+        method: 'GET',
+        headers: {
+          'Accept': 'application/json',
+          'content-type': 'application/json',
+          'x-dutchie-session': sessionId,
+          'apollographql-client-name': 'Marketplace (production)',
+        },
+        credentials: 'include'
+      });
+
+      const json = await response.json();
+      const data = json?.data?.filteredProducts;
+      if (!data?.products) break;
+
+      allProducts.push(...data.products);
+      if (pageNum === 0) totalCount = data.queryInfo?.totalCount || 0;
+      if (allProducts.length >= totalCount) break;
+
+      pageNum++;
+      await new Promise(r => setTimeout(r, 200)); // Polite delay
+    }
+
+    return { products: allProducts, totalCount };
+  }, platformId);
+
+  await browser.close();
+
+  // STEP 3: Save payload
+  const payload = {
+    dispensaryId,
+    platformId,
+    cName,
+    fetchedAt: new Date().toISOString(),
+    productCount: result.products.length,
+    products: result.products,
+  };
+
+  fs.writeFileSync(outputPath, JSON.stringify(payload, null, 2));
+  return payload;
+}
+```
+
+---
+
+## Critical Parameters
+
+### GraphQL Hash (FilteredProducts)
+
+```
+ee29c060826dc41c527e470e9ae502c9b2c169720faa0a9f5d25e1b9a530a4a0
+```
+
+**WARNING:** Using the wrong hash returns HTTP 400.
+
+### Status Parameter
+
+| Value | Result |
+|-------|--------|
+| `'Active'` | Returns in-stock products (1019 in test) |
+| `null` | Returns 0 products |
+| `'All'` | Returns HTTP 400 |
+
+**ALWAYS use `Status: 'Active'`**
+
+### Required Headers
+
+```javascript
+{
+  'Accept': 'application/json',
+  'content-type': 'application/json',
+  'x-dutchie-session': 'unique-session-id',
+  'apollographql-client-name': 'Marketplace (production)',
+}
+```
+
+### Endpoint
+
+```
+https://dutchie.com/api-3/graphql
+```
+
+---
+
+## Performance Benchmarks
+
+Test store: AZ-Deeply-Rooted (1019 products)
+
+| Metric | Value |
+|--------|-------|
+| Total products | 1019 |
+| Time | 18.5 seconds |
+| Payload size | 11.8 MB |
+| Pages fetched | 11 (100 per page) |
+| Success rate | 100% |
+
+---
+
+## Payload Format
+
+The output matches the existing `payload-fetch.ts` handler format:
+
+```json
+{
+  "dispensaryId": 123,
+  "platformId": "6405ef617056e8014d79101b",
+  "cName": "AZ-Deeply-Rooted",
+  "fetchedAt": "2025-12-12T05:05:19.837Z",
+  "productCount": 1019,
+  "products": [
+    {
+      "id": "6927508db4851262f629a869",
+      "Name": "Product Name",
+      "brand": { "name": "Brand Name", ... },
+      "type": "Flower",
+      "THC": "25%",
+      "Prices": [...],
+      "Options": [...],
+      ...
+    }
+  ]
+}
+```
+
+---
+
+## Integration Points
+
+### As a Task Handler
+
+The organic approach can be integrated as an alternative to curl-based fetching:
+
+```typescript
+// In src/tasks/handlers/organic-payload-fetch.ts
+export async function handleOrganicPayloadFetch(ctx: TaskContext): Promise<TaskResult> {
+  // Use puppeteer-based capture
+  // Save to same payload storage
+  // Queue product_refresh task
+}
+```
+
+### Worker Configuration
+
+Add to job_schedules:
+```sql
+INSERT INTO job_schedules (name, role, cron_expression)
+VALUES ('organic_product_crawl', 'organic_payload_fetch', '0 */6 * * *');
+```
+
+---
+
+## Troubleshooting
+
+### HTTP 400 Bad Request
+- Check hash is correct: `ee29c060...`
+- Verify Status is `'Active'` (string, not null)
+
+### 0 Products Returned
+- Status was likely `null` or `'All'` - use `'Active'`
+- Check platformId is valid MongoDB ObjectId
+
+### Session Not Established
+- Increase timeout on initial page.goto()
+- Check cName is valid (matches embedded-menu URL)
+
+### Detection/Blocking
+- StealthPlugin should handle most cases
+- Add random delays between pages
+- Use headless: 'new' (not true/false)
+

+# ARCHIVED DOCUMENTATION
+
+**WARNING: These docs may be outdated or inaccurate.**
+
+The code has evolved significantly. These docs are kept for historical reference only.
+
+## What to Use Instead
+
+**The single source of truth is:**
+- `CLAUDE.md` (root) - Essential rules and quick reference
+- `docs/CODEBASE_MAP.md` - Current file/directory reference
+
+## Why Archive?
+
+These docs were written during development iterations and may reference:
+- Old file paths that no longer exist
+- Deprecated approaches (hydration, scraper-v2)
+- APIs that have changed
+- Database schemas that evolved
+
+## If You Need Details
+
+1. First check CODEBASE_MAP.md for current file locations
+2. Then read the actual source code
+3. Only use archive docs as a last resort for historical context

+| `hydration/` | Old pipeline for processing crawl data | Replaced by `src/tasks/handlers/` |
+| `scraper-v2/` | Old Puppeteer-based scraper engine | Replaced by curl-based `src/platforms/dutchie/client.ts` |
