 ### 5. DB POOL ONLY
 Never import `src/db/migrate.ts` at runtime. Use `src/db/pool.ts` for DB access.
 
+### 6. K8S POD LIMITS — CRITICAL
+**MAX 8 PODS** for `scraper-worker` deployment. NEVER EXCEED THIS.
+
+**Pods vs Workers:**
+- **Pod** = Kubernetes container instance (MAX 8)
+- **Worker** = Concurrent task runner INSIDE a pod (controlled by `MAX_CONCURRENT_TASKS` env var)
+- Formula: `8 pods × MAX_CONCURRENT_TASKS = total concurrent workers`
+
+**To increase workers:** Change `MAX_CONCURRENT_TASKS` env var, NOT replicas.
+```bash
+# CORRECT - increase workers per pod
+kubectl set env deployment/scraper-worker -n dispensary-scraper MAX_CONCURRENT_TASKS=5
+
+# WRONG - never scale above 8 replicas
+kubectl scale deployment/scraper-worker --replicas=20  # NEVER DO THIS
+```
+
+**If K8s API returns ServiceUnavailable:** STOP IMMEDIATELY. Do not retry. The cluster is overloaded.
+
+### 7. K8S REQUIRES EXPLICIT PERMISSION
+**NEVER run kubectl commands without explicit user permission.**
+
+Before running ANY `kubectl` command (scale, rollout, set env, delete, apply, etc.):
+1. Tell the user what you want to do
+2. Wait for explicit approval
+3. Only then execute the command
+
+This applies to ALL kubectl operations - even read-only ones like `kubectl get pods`.

+## Staggered Task Workflow (Added 2025-12-12)
+
+### Overview
+When creating many tasks at once (e.g., product refresh for all AZ stores), staggered scheduling prevents resource contention, proxy assignment lag, and API rate limiting.
+
+### How It Works
+```
+1. Task created with scheduled_for = NOW() + (index * stagger_seconds)
+2. Worker claims task only when scheduled_for <= NOW()
+3. Worker runs preflight on EVERY task claim (proxy health check)
+4. If preflight passes, worker executes task
+5. If preflight fails, task released back to pending for another worker
+6. Worker finishes task, polls for next available task
+7. Repeat - preflight runs on each new task claim
+```
+
+### Key Points
+- **Preflight is per-task, not per-startup**: Each task claim triggers a new preflight check
+- **Stagger prevents thundering herd**: 15 seconds between tasks is default
+- **Task assignment is the trigger**: Worker picks up task → runs preflight → executes if passed
+
+### API Endpoints
+```bash
+# Create staggered tasks for specific dispensary IDs
+POST /api/tasks/batch/staggered
+{
+  "dispensary_ids": [1, 2, 3, 4],
+  "role": "product_refresh",      # or "product_discovery"
+  "stagger_seconds": 15,          # default: 15
+  "platform": "dutchie",          # default: "dutchie"
+  "method": null                  # "curl" | "http" | null
+}
+
+# Create staggered tasks for AZ stores (convenience endpoint)
+POST /api/tasks/batch/az-stores
+{
+  "total_tasks": 24,              # default: 24
+  "stagger_seconds": 15,          # default: 15
+  "split_roles": true             # default: true (12 refresh, 12 discovery)
+}
+```
+
+### Example: 24 Tasks for AZ Stores
+```bash
+curl -X POST http://localhost:3010/api/tasks/batch/az-stores \
+  -H "Content-Type: application/json" \
+  -d '{"total_tasks": 24, "stagger_seconds": 15, "split_roles": true}'
+```
+
+Response:
+```json
+{
+  "success": true,
+  "total": 24,
+  "product_refresh": 12,
+  "product_discovery": 12,
+  "stagger_seconds": 15,
+  "total_duration_seconds": 345,

+   * the previous task.
+   *
+   * Workflow:
+   * 1. Task is created with scheduled_for = NOW() + (index * staggerSeconds)
+   * 2. Worker claims task only when scheduled_for <= NOW()
+   * 3. Worker runs preflight check on EVERY task claim
+   * 4. If preflight passes, worker executes task
+   * 5. If preflight fails, task is released back to pending for another worker
+   * 6. Worker finishes task, polls for next available task
+   * 7. Repeat - preflight runs again on next task claim
+   *
+   * Benefits:
+   * - Prevents all 8 workers from hitting proxies simultaneously
+   * - Reduces API rate limiting / 403 errors
+   * - Spreads resource usage over time
+   * - Each task still runs preflight, ensuring proxy health
