     - **Trigger schedules manually**: `curl -X POST /api/az/admin/schedules/{id}/trigger`
     - **Check schedule status**: `curl /api/az/admin/schedules`
     - **Worker logs**: `kubectl logs -f deployment/scraper-worker -n dispensary-scraper`

+24) **Crawler Maintenance Procedure (Check Jobs, Requeue, Restart)**
+    When crawlers are stuck or jobs aren't processing, follow this procedure:
+
+    **Step 1: Check Job Status**
+    ```bash
+    # Port-forward to production
+    kubectl port-forward -n dispensary-scraper deployment/scraper 3099:3010 &
+
+    # Check active/stuck jobs
+    curl -s http://localhost:3099/api/az/monitor/active-jobs | jq .
+
+    # Check recent job history
+    curl -s "http://localhost:3099/api/az/monitor/jobs?limit=20" | jq '.jobs[] | {id, job_type, status, dispensary_id, started_at, products_found, duration_min: (.duration_ms/60000 | floor)}'
+
+    # Check schedule status
+    curl -s http://localhost:3099/api/az/admin/schedules | jq '.schedules[] | {id, jobName, enabled, lastRunAt, lastStatus, nextRunAt}'
+    ```
+
+    **Step 2: Reset Stuck Jobs**
+    Jobs are considered stuck if they have `status='running'` but no heartbeat in >30 minutes:
+    ```bash
+    # Via API (if endpoint exists)
+    curl -s -X POST http://localhost:3099/api/az/admin/reset-stuck-jobs
+
+    # Via direct DB (if API not available)
+    kubectl exec -n dispensary-scraper deployment/scraper -- psql $DATABASE_URL -c "
+      UPDATE dispensary_crawl_jobs
+      SET status = 'failed',
+          error_message = 'Job timed out - worker stopped sending heartbeats',
+          completed_at = NOW()
+      WHERE status = 'running'
+        AND (last_heartbeat_at < NOW() - INTERVAL '30 minutes' OR last_heartbeat_at IS NULL);
+    "
+    ```
+
+    **Step 3: Requeue Jobs (Trigger Fresh Crawl)**
+    ```bash
+    # Trigger product crawl schedule (typically ID 1)
+    curl -s -X POST http://localhost:3099/api/az/admin/schedules/1/trigger
+
+    # Trigger menu detection schedule (typically ID 2)
+    curl -s -X POST http://localhost:3099/api/az/admin/schedules/2/trigger
+
+    # Or crawl a specific dispensary
+    curl -s -X POST http://localhost:3099/api/az/admin/crawl/112
+    ```
+
+    **Step 4: Restart Crawler Workers**
+    ```bash
+    # Restart scraper-worker pods (clears any stuck processes)
+    kubectl rollout restart deployment/scraper-worker -n dispensary-scraper
+
+    # Watch rollout progress
+    kubectl rollout status deployment/scraper-worker -n dispensary-scraper
+
+    # Optionally restart main scraper pod too
+    kubectl rollout restart deployment/scraper -n dispensary-scraper
+    ```
+
+    **Step 5: Monitor Recovery**
+    ```bash
+    # Watch worker logs
+    kubectl logs -f deployment/scraper-worker -n dispensary-scraper --tail=50
+
+    # Check dashboard for product counts
+    curl -s http://localhost:3099/api/az/dashboard | jq '{totalStores, totalProducts, storesByType}'
+
+    # Verify jobs are processing
+    curl -s http://localhost:3099/api/az/monitor/active-jobs | jq .
+    ```
+
+    **Quick One-Liner for Full Reset:**
+    ```bash
+    # Reset stuck jobs and restart workers
+    kubectl exec -n dispensary-scraper deployment/scraper -- psql $DATABASE_URL -c "UPDATE dispensary_crawl_jobs SET status='failed', completed_at=NOW() WHERE status='running' AND (last_heartbeat_at < NOW() - INTERVAL '30 minutes' OR last_heartbeat_at IS NULL);" && kubectl rollout restart deployment/scraper-worker -n dispensary-scraper && kubectl rollout status deployment/scraper-worker -n dispensary-scraper
+    ```
+
+    **Cleanup port-forwards when done:**
+    ```bash
+    pkill -f "port-forward.*dispensary-scraper"
+    ```
