+

+
+## Default Schedules
+
+| Name | Role | Interval | Priority | Description |
+|------|------|----------|----------|-------------|
+| `payload_fetch_all` | payload_fetch | 4 hours | 0 | Fetch payloads from Dutchie API (chains to product_refresh) |
+| `store_discovery_dutchie` | store_discovery | 24 hours | 5 | Find new Dutchie stores |
+| `analytics_refresh` | analytics_refresh | 6 hours | 0 | Refresh MVs |
+
+---
+
+## Task Roles
+
+| Role | Description | Creates Tasks For |
+|------|-------------|-------------------|
+| `payload_fetch` | **NEW** - Fetch from Dutchie API, save to disk | Each dispensary needing crawl |
+| `product_refresh` | **CHANGED** - Read local payload, normalize, upsert to DB | Chained from payload_fetch |
+| `store_discovery` | Find new dispensaries, returns newStoreIds[] | Single task per platform |
+| `entry_point_discovery` | **DEPRECATED** - Resolve platform IDs | No longer used |
+| `product_discovery` | Initial product fetch for new stores | Chained from store_discovery |
+| `analytics_refresh` | Refresh MVs | Single global task |
+
+### Payload/Refresh Separation (2024-12-10)
+
+The crawl workflow is now split into two phases:
+
+```
+payload_fetch (scheduled every 4h)
+  └─► Hit Dutchie GraphQL API
+  └─► Save raw JSON to /storage/payloads/{year}/{month}/{day}/store_{id}_{ts}.json.gz
+  └─► Record metadata in raw_crawl_payloads table
+  └─► Queue product_refresh task with payload_id
+
+product_refresh (chained from payload_fetch)
+  └─► Load payload from filesystem (NOT from API)
+  └─► Normalize via DutchieNormalizer
+  └─► Upsert to store_products
+  └─► Create snapshots
+  └─► Track missing products
+  └─► Download images
+```
+
+**Benefits:**
+- **Retry-friendly**: If normalize fails, re-run product_refresh without re-crawling
+- **Replay-able**: Run product_refresh against any historical payload
+- **Faster refreshes**: Local file read vs network call
+- **Historical diffs**: Compare payloads to see what changed between crawls
+- **Less API pressure**: Only payload_fetch hits Dutchie
+
+---
+
+## Task Chaining
+
+Tasks automatically queue follow-up tasks upon successful completion. This creates two main flows:
+
+### Discovery Flow (New Stores)
+
+When `store_discovery` finds new dispensaries, they automatically get their initial product data:
+
+```
+store_discovery
+  └─► Discovers new locations via Dutchie GraphQL
+  └─► Auto-promotes valid locations to dispensaries table
+  └─► Collects newDispensaryIds[] from promotions
+  └─► Returns { newStoreIds: [...] } in result
+
+chainNextTask() detects newStoreIds
+  └─► Creates product_discovery task for each new store
+
+product_discovery
+  └─► Calls handlePayloadFetch() internally
+  └─► payload_fetch hits Dutchie API
+  └─► Saves raw JSON to /storage/payloads/
+  └─► Queues product_refresh task with payload_id
+
+product_refresh
+  └─► Loads payload from filesystem
+  └─► Normalizes and upserts to store_products
+  └─► Creates snapshots, downloads images
+```
+
+**Complete Discovery Chain:**
+```
+store_discovery → product_discovery → payload_fetch → product_refresh
+                        (internal call)    (queues next)
+```
+
+### Scheduled Flow (Existing Stores)
+
+For existing stores, `payload_fetch_all` schedule runs every 4 hours:
+
+```
+TaskScheduler (every 60s)
+  └─► Checks task_schedules for due schedules
+  └─► payload_fetch_all is due
+  └─► Generates payload_fetch task for each dispensary
+
+payload_fetch
+  └─► Hits Dutchie GraphQL API
+  └─► Saves raw JSON to /storage/payloads/
+  └─► Queues product_refresh task with payload_id
+
+product_refresh
+  └─► Loads payload from filesystem (NOT API)
+  └─► Normalizes via DutchieNormalizer
+  └─► Upserts to store_products
+  └─► Creates snapshots
+```
+
+**Complete Scheduled Chain:**
+```
+payload_fetch → product_refresh
+  (queues)        (reads local)
+```
+
+### Chaining Implementation
+
+Task chaining is handled in two places:
+
+1. **Internal chaining (handler calls handler):**
+   - `product_discovery` calls `handlePayloadFetch()` directly
+
+2. **External chaining (chainNextTask() in task-service.ts):**
+   - Called after task completion
+   - `store_discovery` → queues `product_discovery` for each newStoreId
+
+3. **Queue-based chaining (taskService.createTask):**
+   - `payload_fetch` queues `product_refresh` with `payload: { payload_id }`
+
+---
+
+## Payload API Endpoints
+
+Raw crawl payloads can be accessed via the Payloads API:
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `GET /api/payloads` | GET | List payload metadata (paginated) |

+  "details": {
+    "added": [...],
+    "removed": [...],
+    "priceChanges": [...],
+    "stockChanges": [...]
+  }
+}
+```
+

+| `src/tasks/task-worker.ts` | Worker that processes tasks |
+| `src/tasks/task-service.ts` | Task CRUD operations |
+| `src/tasks/handlers/payload-fetch.ts` | **NEW** - Fetches from API, saves to disk |
+| `src/tasks/handlers/product-refresh.ts` | **CHANGED** - Reads from disk, processes to DB |

+
+## Legacy Code (DEPRECATED)
+
+| File | Status | Replacement |
+|------|--------|-------------|
+| `src/services/scheduler.ts` | DEPRECATED | `task-scheduler.ts` |
+| `dispensary_crawl_jobs` table | ORPHANED | `worker_tasks` |
+| `job_schedules` table | LEGACY | `task_schedules` |
+
+---
+
+## Dashboard Integration
+
+Both pages remain wired to the dashboard:
+
+| Page | Data Source | Actions |
+|------|-------------|---------|
+| **Job Queue** | `worker_tasks`, `task_schedules` | Create tasks, view schedules |
+| **Task Queue** | `worker_tasks` | View tasks, recover stale |
+
+---
+
+## Multi-Replica Safety
+
+The scheduler uses `SELECT FOR UPDATE SKIP LOCKED` to ensure:
+
+1. **Only one replica** executes a schedule at a time
+2. **No duplicate tasks** created
+3. **Survives pod restarts** - state in DB, not memory
+4. **Self-healing** - recovers stale tasks on startup
+
+```sql
+-- This query is atomic across all API server replicas
+SELECT * FROM task_schedules
+WHERE enabled = true AND next_run_at <= NOW()
+FOR UPDATE SKIP LOCKED
+```
+
+---
+
+## Worker Scaling (K8s)
+
+Workers run as a StatefulSet in Kubernetes. You can scale from the admin UI or CLI.
+
+### From Admin UI
+
+The Workers page (`/admin/workers`) provides:
+- Current replica count display
+- Scale up/down buttons
+- Target replica input
+
+### API Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `GET /api/workers/k8s/replicas` | GET | Get current/desired replica counts |
+| `POST /api/workers/k8s/scale` | POST | Scale to N replicas (body: `{ replicas: N }`) |
+
+### From CLI
+
+```bash
+# View current replicas
+kubectl get statefulset scraper-worker -n dispensary-scraper
+
+# Scale to 10 workers
+kubectl scale statefulset scraper-worker -n dispensary-scraper --replicas=10
+
+# Scale down to 3 workers
+kubectl scale statefulset scraper-worker -n dispensary-scraper --replicas=3
+```
+
+### Configuration
+
+Environment variables for the API server:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `K8S_NAMESPACE` | `dispensary-scraper` | Kubernetes namespace |
+| `K8S_WORKER_STATEFULSET` | `scraper-worker` | StatefulSet name |
+
+### RBAC Requirements
+
+The API server pod needs these K8s permissions:
+
+```yaml
+apiVersion: rbac.authorization.k8s.io/v1
+kind: Role
+metadata:
+  name: worker-scaler
+  namespace: dispensary-scraper
+rules:
+- apiGroups: ["apps"]
+  resources: ["statefulsets"]
+  verbs: ["get", "patch"]

- * This is the canonical HTTP client for all Dutchie communication.
- * All Dutchie workers (Alice, Bella, etc.) MUST use this client.
+ * Updated: 2025-12-10 per workflow-12102025.md
+ *
+ * KEY BEHAVIORS (per workflow-12102025.md):
+ * 1. startSession() gets identity from PROXY LOCATION, not task params
+ * 2. On 403: immediately get new IP + new fingerprint, then retry
+ * 3. After 3 consecutive 403s on same proxy → disable it (burned)
+ * 4. Language is always English (en-US)
  *
  * IMPLEMENTATION:
  * - Uses curl via child_process.execSync (bypasses TLS fingerprinting)
  * - NO Puppeteer, NO axios, NO fetch
- * - Fingerprint rotation on 403
+ * - Uses intoli/user-agents via CrawlRotator for realistic fingerprints
  * - Residential IP compatible
  *
  * USAGE:
- *   import { curlPost, curlGet, executeGraphQL } from '@dutchie/client';
+ *   import { curlPost, curlGet, executeGraphQL, startSession } from '@dutchie/client';

  * Crawl Rotator - Proxy & User Agent Rotation for Crawlers

+ *
+ * KEY BEHAVIORS (per workflow-12102025.md):
+ * 1. Task determines WHAT work to do, proxy determines SESSION IDENTITY
+ * 2. Proxy location (timezone) sets Accept-Language headers (always English)
+ * 3. On 403: immediately get new IP, new fingerprint, retry
+ * 4. After 3 consecutive 403s on same proxy with different fingerprints → disable proxy
+ *
+ * USER-AGENT GENERATION (per workflow-12102025.md):
+ * - Device distribution: Mobile 62%, Desktop 36%, Tablet 2%
+ * - Browser whitelist: Chrome, Safari, Edge, Firefox only
+ * - UA sticks until IP rotates
+ * - Failure = alert admin + stop crawl (no fallback)

+/**
+ * Payload Storage Utility
+ *
+ * Per TASK_WORKFLOW_2024-12-10.md: Store raw GraphQL payloads for historical analysis.
+ *
+ * Design Pattern: Metadata/Payload Separation
+ * - Metadata in PostgreSQL (raw_crawl_payloads table): Small, indexed, queryable
+ * - Payload on filesystem: Gzipped JSON at storage_path
+ *
+ * Storage structure:
+ *   /storage/payloads/{year}/{month}/{day}/store_{dispensary_id}_{timestamp}.json.gz
+ *
+ * Benefits:
+ * - Compare any two crawls to see what changed
+ * - Replay/re-normalize historical data if logic changes
+ * - Debug issues by seeing exactly what the API returned
+ * - DB stays small, backups stay fast
+ * - ~90% compression (1.5MB -> 150KB per crawl)

+# Workflow Documentation - December 10, 2025
+
+## Purpose
+
+This document captures the intended behavior for the CannaiQ crawl system, specifically around proxy rotation, fingerprinting, and anti-detection.
+
+---
+
+## Stealth & Anti-Detection Requirements
+
+### 1. Task Determines Work, Proxy Determines Identity
+
+The task payload contains:
+- `dispensary_id` - which store to crawl
+- `role` - what type of work (product_resync, entry_point_discovery, etc.)
+
+The **proxy** determines the session identity:
+- Proxy location (city, state, timezone) → sets Accept-Language and timezone headers
+- Language is always English (`en-US`)
+
+**Flow:**
+```
+Task claimed
+    │
+    └─► Get proxy from rotation
+            │
+            └─► Proxy has location (city, state, timezone)
+                    │
+                    └─► Build headers using proxy's timezone
+                            - Accept-Language: en-US,en;q=0.9
+                            - Timezone-consistent behavior
+```
+
+### 2. On 403 Block - Immediate Backoff
+
+When a 403 is received:
+
+1. **Immediately** stop using current IP
+2. Get a new proxy (new IP)
+3. Get a new UA/fingerprint
+4. Retry the request
+
+**Per-proxy failure tracking:**
+- Track UA rotation attempts per proxy
+- After 3 UA/fingerprint rotations on the same proxy → disable that proxy
+- This means: if we rotate UA 3 times and still get 403, the proxy is burned
+
+### 3. Fingerprint Rotation Rules
+
+Each request uses:
+- Proxy (IP)
+- User-Agent
+- sec-ch-ua headers (Client Hints)
+- Accept-Language (from proxy location)
+
+On 403:
+1. Record failure on current proxy
+2. Rotate to new proxy
+3. Pick new random fingerprint
+4. If same proxy fails 3 times with different fingerprints → disable proxy
+
+### 4. Proxy Table Schema
+
+```sql
+CREATE TABLE proxies (
+  id SERIAL PRIMARY KEY,
+  host VARCHAR(255) NOT NULL,
+  port INTEGER NOT NULL,
+  username VARCHAR(100),
+  password VARCHAR(100),
+  protocol VARCHAR(10) DEFAULT 'http',
+  active BOOLEAN DEFAULT true,
+
+  -- Location (determines session headers)
+  city VARCHAR(100),
+  state VARCHAR(50),
+  country VARCHAR(100),
+  country_code VARCHAR(10),
+  timezone VARCHAR(50),
+
+  -- Health tracking
+  failure_count INTEGER DEFAULT 0,
+  consecutive_403_count INTEGER DEFAULT 0,  -- Track 403s specifically
+  last_used_at TIMESTAMPTZ,
+  last_failure_at TIMESTAMPTZ,
+  last_error TEXT,
+
+  -- Performance
+  response_time_ms INTEGER,
+  max_connections INTEGER DEFAULT 1
+);
+```
+
+### 5. Failure Threshold
+
+- **3 consecutive 403s** with different fingerprints → disable proxy
+- Reset `consecutive_403_count` to 0 on successful request
+- General `failure_count` tracks all errors (timeouts, connection errors, etc.)
+
+---
+
+## Implementation Status
+
+### COMPLETED - December 10, 2025
+
+All code changes have been implemented per this specification:
+
+#### 1. crawl-rotator.ts ✅
+
+- [x] Added `consecutive403Count` to Proxy interface
+- [x] Added `markBlocked()` method that increments `consecutive_403_count` and disables proxy at 3
+- [x] Added `getProxyTimezone()` to return current proxy's timezone
+- [x] `markSuccess()` now resets `consecutive_403_count` to 0
+- [x] Replaced hardcoded UA list with `intoli/user-agents` library for realistic fingerprints
+- [x] `BrowserFingerprint` interface includes full fingerprint data (UA, platform, screen size, viewport, sec-ch-ua headers)
+
+#### 2. client.ts ✅
+
+- [x] `startSession()` no longer takes state/timezone params
+- [x] `startSession()` gets identity from proxy via `crawlRotator.getProxyLocation()`
+- [x] Added `handle403Block()` that:
+  - Calls `crawlRotator.recordBlock()` (tracks consecutive 403s)
+  - Immediately rotates both proxy and fingerprint via `rotateBoth()`
+  - Returns false if no more proxies available
+- [x] `executeGraphQL()` calls `handle403Block()` on 403 (not `rotateProxyOn403`)
+- [x] `fetchPage()` uses same 403 handling
+- [x] 500ms backoff after rotation (not linear delay)
+
+#### 3. Task Handlers ✅
+
+- [x] `entry-point-discovery.ts`: `startSession()` called with no params
+- [x] `product-refresh.ts`: `startSession()` called with no params
+
+#### 4. Dependencies ✅
+
+- [x] Added `user-agents` npm package for realistic UA generation
+
+---
+
+## Files Changed
+
+| File | Changes |
+|------|---------|
+| `backend/src/services/crawl-rotator.ts` | Complete rewrite with `consecutive403Count`, `markBlocked()`, `intoli/user-agents` |
+| `backend/src/platforms/dutchie/client.ts` | `startSession()` uses proxy location, `handle403Block()` for 403 handling |
+| `backend/src/tasks/handlers/entry-point-discovery.ts` | `startSession()` no params |
+| `backend/src/tasks/handlers/product-refresh.ts` | `startSession()` no params |
+| `backend/package.json` | Added `user-agents` dependency |
+
+---
+
+## Migration Required
+
+The `proxies` table needs `consecutive_403_count` column if not already present:
+
+```sql
+ALTER TABLE proxies ADD COLUMN IF NOT EXISTS consecutive_403_count INTEGER DEFAULT 0;
+```
+
+---
+
+## Key Behaviors Summary
+
+| Behavior | Implementation |
+|----------|----------------|
+| Session identity | From proxy location (`getProxyLocation()`) |
+| Language | Always `en-US,en;q=0.9` |
+| 403 handling | `handle403Block()` → `recordBlock()` → `rotateBoth()` |
+| Proxy disable | After 3 consecutive 403s (`consecutive403Count >= 3`) |
+| Success reset | `markSuccess()` resets `consecutive403Count` to 0 |
+| UA generation | `intoli/user-agents` library (daily updated, realistic fingerprints) |
+| Fingerprint data | Full: UA, platform, screen size, viewport, sec-ch-ua headers |
+
+---
+
+## User-Agent Generation
+
+### Data Source
+
+The `intoli/user-agents` npm library provides daily-updated market share data collected from Intoli's residential proxy network (millions of real users). The package auto-releases new versions daily to npm.
+
+### Device Category Distribution (hardcoded)
+
+| Category | Share |
+|----------|-------|
+| Mobile | 62% |
+| Desktop | 36% |
+| Tablet | 2% |
+
+### Browser Filter (whitelist only)
+
+Only these browsers are allowed:
+- Chrome (67%)
+- Safari (20%)
+- Edge (6%)
+- Firefox (3%)
+
+Samsung Internet, Opera, and other niche browsers are filtered out.
+
+### Desktop OS Distribution (from library)
+
+| OS | Share |
+|----|-------|
+| Windows | 72% |
+| macOS | 17% |
+| Linux | 4% |
+
+### UA Lifecycle
+
+1. **Session start** (new proxy IP obtained) → Roll device category (62/36/2) → Generate UA filtered to device + top 4 browsers → Store on session
+2. **UA sticks** until IP rotates (403 block or manual rotation)
+3. **IP rotation** triggers new UA generation
+
+### Failure Handling
+
+- If UA generation fails → Alert admin dashboard, **stop crawl immediately**
+- No fallback to static UA list
+- This forces investigation rather than silent degradation
+
+### Session Logging
+
+Each session logs:
+- Device category (mobile/desktop/tablet)
+- Full UA string
+- Browser name (Chrome/Safari/Edge/Firefox)
+- IP address (from proxy)
+- Session start timestamp
+
+Logs are rotated monthly.
+
+### Implementation
+
+Located in `backend/src/services/crawl-rotator.ts`:
+
+```typescript
+// Per workflow-12102025.md: Device category distribution
+const DEVICE_WEIGHTS = { mobile: 62, desktop: 36, tablet: 2 };
+
+// Per workflow-12102025.md: Browser whitelist
+const ALLOWED_BROWSERS = ['Chrome', 'Safari', 'Edge', 'Firefox'];
+```
+
+---
+
+## HTTP Fingerprinting
+
+### Goal
+
+Make HTTP requests indistinguishable from real browser traffic. No repeatable footprint.
+
+### Components
+
+1. **Full Header Set** - All headers a real browser sends
+2. **Header Ordering** - Browser-specific order (Chrome vs Firefox vs Safari)
+3. **TLS Fingerprint** - Use `curl-impersonate` to match browser TLS signature
+4. **Dynamic Referer** - Set per dispensary being crawled
+5. **Natural Randomization** - Vary optional headers like real users
+
+### Required Headers
+
+| Header | Chrome | Firefox | Safari | Notes |
+|--------|--------|---------|--------|-------|
+| `User-Agent` | ✅ | ✅ | ✅ | From UA generation |
+| `Accept` | ✅ | ✅ | ✅ | Content types |
+| `Accept-Language` | ✅ | ✅ | ✅ | Always `en-US,en;q=0.9` |
+| `Accept-Encoding` | ✅ | ✅ | ✅ | `gzip, deflate, br` |
+| `Connection` | ✅ | ✅ | ✅ | `keep-alive` |
+| `Origin` | ✅ | ✅ | ✅ | `https://dutchie.com` (POST only) |
+| `Referer` | ✅ | ✅ | ✅ | Dynamic per dispensary |
+| `sec-ch-ua` | ✅ | ❌ | ❌ | Chromium only |
+| `sec-ch-ua-mobile` | ✅ | ❌ | ❌ | Chromium only |
+| `sec-ch-ua-platform` | ✅ | ❌ | ❌ | Chromium only |
+| `sec-fetch-dest` | ✅ | ✅ | ❌ | `empty` for XHR |
+| `sec-fetch-mode` | ✅ | ✅ | ❌ | `cors` for XHR |
+| `sec-fetch-site` | ✅ | ✅ | ❌ | `same-origin` |
+| `Upgrade-Insecure-Requests` | ✅ | ✅ | ✅ | `1` (page loads only) |
+| `DNT` | ~30% | ~30% | ~30% | Randomized per session |
+
+### Header Ordering
+
+Each browser sends headers in a specific order. Fingerprinting services detect mismatches.
+
+**Chrome order (GraphQL request):**
+1. Host
+2. Connection
+3. Content-Length (POST)
+4. sec-ch-ua
+5. DNT (if enabled)
+6. sec-ch-ua-mobile
+7. User-Agent
+8. sec-ch-ua-platform
+9. Content-Type (POST)
+10. Accept
+11. Origin (POST)
+12. sec-fetch-site
+13. sec-fetch-mode
+14. sec-fetch-dest
+15. Referer
+16. Accept-Encoding
+17. Accept-Language
+
+**Firefox order (GraphQL request):**
+1. Host
+2. User-Agent
+3. Accept
+4. Accept-Language
+5. Accept-Encoding
+6. Content-Type (POST)
+7. Content-Length (POST)
+8. Origin (POST)
+9. DNT (if enabled)
+10. Connection
+11. Referer
+12. sec-fetch-dest
+13. sec-fetch-mode
+14. sec-fetch-site
+
+**Safari order (GraphQL request):**
+1. Host
+2. Connection
+3. Content-Length (POST)
+4. Accept
+5. User-Agent
+6. Content-Type (POST)
+7. Origin (POST)
+8. Referer
+9. Accept-Encoding
+10. Accept-Language
+
+### TLS Fingerprinting
+
+Use `curl-impersonate` instead of standard curl:
+- `curl_chrome131` - Mimics Chrome 131 TLS handshake
+- `curl_ff133` - Mimics Firefox 133 TLS handshake
+- `curl_safari17` - Mimics Safari 17 TLS handshake
+
+Match TLS binary to browser in UA.
+
+### Dynamic Referer
+
+Set Referer to the dispensary's actual page URL:
+
+```
+Crawling "harvest-of-tempe" → Referer: https://dutchie.com/dispensary/harvest-of-tempe
+Crawling "zen-leaf-mesa" → Referer: https://dutchie.com/dispensary/zen-leaf-mesa
+```
+
+Derived from dispensary's `menu_url` field.
+
+### Natural Randomization
+
+Per-session randomization (set once when session starts, consistent for session):
+
+| Feature | Distribution | Implementation |
+|---------|--------------|----------------|
+| DNT header | 30% have it | `Math.random() < 0.30` |
