fix: Use registry.spdy.io for all CI images + fix TypeScript errors

- Update .woodpecker.yml to use registry.spdy.io for node, alpine, kaniko, kubectl images
- Fix Buffer type errors in script files (Node 22 TypeScript compatibility)
- Add explicit typing for Map iterations in diff scripts

+### 7. K8S — DEPLOY AND FORGET
+**DO NOT run kubectl commands.** The system is self-managing.
 
-**Replica Count is LOCKED:**
-- Always 8 replicas — no more, no less
-- NEVER scale down (even temporarily)
-- NEVER scale up beyond 8
-- If pods are not 8, restore to 8 immediately
+**Operational Model:**
+```
+┌─────────────────────────────────────────────────────────┐
+│  DEPLOY ONCE → WORKERS RUN FOREVER → CREATE TASKS ONLY │
+└─────────────────────────────────────────────────────────┘
 
-**Pods vs Workers:**
-- **Pod** = Kubernetes container instance (ALWAYS 8)
-- **Worker** = Concurrent task runner INSIDE a pod (controlled by `MAX_CONCURRENT_TASKS` env var)
-- Formula: `8 pods × MAX_CONCURRENT_TASKS = 24 total concurrent workers`
-
-**Browser Task Memory Limits:**
-- Each Puppeteer/Chrome browser uses ~400 MB RAM
-- Pod memory limit is 2 GB
-- **MAX_CONCURRENT_TASKS=3** is the safe maximum for browser tasks
-- More than 3 concurrent browsers per pod = OOM crash
-
-| Browsers | RAM Used | Status |
-|----------|----------|--------|
-| 3 | ~1.3 GB | Safe (recommended) |
-| 4 | ~1.7 GB | Risky |
-| 5+ | >2 GB | OOM crash |
-
-**To increase throughput:** Add more pods (up to 8), NOT more concurrent tasks per pod.
-
-```bash
-# CORRECT - scale pods (up to 8)
-kubectl scale deployment/scraper-worker -n dispensary-scraper --replicas=8
-
-# WRONG - will cause OOM crashes
-kubectl set env deployment/scraper-worker -n dispensary-scraper MAX_CONCURRENT_TASKS=10
+1. CI deploys code changes (automatic on push)
+2. K8s maintains 8 pods (self-healing)
+3. Workers poll DB for tasks (autonomous)
+4. Create tasks via API or DB → workers pick them up
+5. Never touch K8s directly
 ```
 
-**If K8s API returns ServiceUnavailable:** STOP IMMEDIATELY. Do not retry. The cluster is overloaded.
+**Fixed Configuration (NEVER CHANGE):**
+- **8 replicas** — locked in `k8s/scraper-worker.yaml`
+- **MAX_CONCURRENT_TASKS=3** — 3 browsers per pod (memory safe)
+- **Total capacity:** 8 pods × 3 = 24 concurrent tasks
 
-### 7. K8S REQUIRES EXPLICIT PERMISSION
-**NEVER run kubectl commands without explicit user permission.**
+**DO NOT:**
+- Run `kubectl` commands (scale, rollout, logs, get pods, etc.)
+- Manually restart pods
+- Change replica count
+- Check deployment status
 
-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
+**To interact with the system:**
+- Create tasks in DB → workers pick them up automatically
+- Check task status via DB queries or API
+- View worker status via dashboard (cannaiq.co)
 
-This applies to ALL kubectl operations - even read-only ones like `kubectl get pods`.
+**Why no kubectl?**
+- K8s auto-restarts crashed pods
+- Workers self-heal (reconnect to DB, retry failed tasks)
+- No manual intervention needed in steady state
+- Only CI touches K8s (on code deployments)
+
+**Scaling Decision:**
+- Monitor pool drain rate via dashboard/DB queries
+- If pool drains too slowly, manually increase replicas in `k8s/scraper-worker.yaml`
+- Commit + push → CI deploys new replica count
+- No runtime kubectl scaling — all changes via code

+## Wasabi S3 Storage (Payload Archive)
+
+Raw crawl payloads are archived to Wasabi S3 for long-term storage and potential reprocessing.
+
+### Configuration
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `WASABI_ACCESS_KEY` | Wasabi access key ID | - |
+| `WASABI_SECRET_KEY` | Wasabi secret access key | - |
+| `WASABI_BUCKET` | Bucket name | `cannaiq` |
+| `WASABI_REGION` | Wasabi region | `us-west-2` |
+| `WASABI_ENDPOINT` | S3 endpoint URL | `https://s3.us-west-2.wasabisys.com` |
+
+### Storage Path Format
+```
+payloads/{state}/{YYYY-MM-DD}/{dispensary_id}/{platform}_{timestamp}.json.gz
+```
+
+Example: `payloads/AZ/2025-12-16/123/dutchie_2025-12-16T10-30-00-000Z.json.gz`
+
+### Features
+- **Gzip compression**: ~70% size reduction on JSON payloads
+- **Automatic archival**: Every crawl is archived (not just daily baselines)
+- **Metadata**: taskId, productCount, platform stored with each object
+- **Graceful fallback**: If Wasabi not configured, archival is skipped (no task failure)
+
+### Files
+| File | Purpose |
+|------|---------|
+| `src/services/wasabi-storage.ts` | S3 client and storage functions |
+| `src/tasks/handlers/product-discovery-dutchie.ts` | Archives Dutchie payloads |
+| `src/tasks/handlers/product-discovery-jane.ts` | Archives Jane payloads |
+| `src/tasks/handlers/product-discovery-treez.ts` | Archives Treez payloads |
+
+### K8s Secret Setup
+```bash
+kubectl patch secret scraper-secrets -n cannaiq -p '{"stringData":{
+  "WASABI_ACCESS_KEY": "<access-key>",
+  "WASABI_SECRET_KEY": "<secret-key>"
+}}'
+```
+
+### Usage in Code
+```typescript
+import { storePayload, getPayload, listPayloads } from '../services/wasabi-storage';
+
+// Store a payload
+const result = await storePayload(dispensaryId, 'AZ', 'dutchie', rawPayload);
+console.log(result.path);           // payloads/AZ/2025-12-16/123/dutchie_...
+console.log(result.compressedBytes); // Size after gzip
+
+// Retrieve a payload
+const payload = await getPayload(result.path);
+
+// List payloads for a store on a date
+const paths = await listPayloads(123, 'AZ', '2025-12-16');
+```
+
+### Estimated Storage
+- ~100KB per crawl (compressed)
+- ~200 stores × 12 crawls/day = 240MB/day
+- ~7.2GB/month
+- 5TB capacity = ~5+ years of storage
+
+---
+
+## Real-Time Inventory Tracking
+
+High-frequency crawling for sales velocity and inventory analytics.
+
+### Crawl Intervals
+
+| State | Interval | Jitter | Effective Range |
+|-------|----------|--------|-----------------|
+| AZ | 5 min | ±3 min | 2-8 min |
+| Others | 60 min | ±3 min | 57-63 min |
+
+### Delta-Only Snapshots
+
+Only store inventory changes, not full state. Reduces storage by ~95%.
+
+**Change Types**:
+- `sale`: quantity decreased (qty_delta < 0)
+- `restock`: quantity increased (qty_delta > 0)
+- `price_change`: price changed, quantity same
+- `oos`: went out of stock (qty → 0)
+- `back_in_stock`: returned to stock (0 → qty)
+- `new_product`: first time seeing product
+
+### Revenue Calculation
+```
+revenue = ABS(qty_delta) × effective_price
+effective_price = sale_price if on_special else regular_price
+```
+
+### Key Views
+| View | Purpose |
+|------|---------|
+| `v_hourly_sales` | Sales aggregated by hour |
+| `v_daily_store_sales` | Daily revenue by store |
+| `v_daily_brand_sales` | Daily brand performance |
+| `v_product_velocity` | Hot/steady/slow/stale rankings |
+| `v_stock_out_prediction` | Days until OOS based on velocity |
+| `v_brand_variants` | SKU counts per brand |

+| **new** | Product launches, brand expansion |
+| **removed** | Discontinued products, seasonal items |
+| **price_change** | Pricing strategy, promotions |
+| **cannabinoid_change** | Quality/potency changes |
+| **effect_change** | Consumer feedback updates |

+## Revenue Formula
+
+For every sale:
+```
+revenue = ABS(quantity_delta) × effective_price
+
+effective_price = is_special ? special_price : price
+```
+
+Example:
+- Product: Clout King Flower Jar | Hood Snacks (1/8oz)
+- Regular price: $45.00
+- Special price: $33.75
+- is_special: true
+- quantity_delta: -2
+
+**Revenue = 2 × $33.75 = $67.50**
+
+---
+
+## Data Quality
+
+### Deduplication
+- Hash each payload to prevent reprocessing
+- Track `payload_processing_log` for audit trail
+
+### Consistency
+- Use daily snapshots as baseline for new product detection
+- Compare consecutive payloads for change detection
+
+### Coverage
+- Track all 987+ products per store
+- All variants/options (1/8oz, 1/4oz, 1/2oz, etc.)
+- Full cannabinoid profiles (THC, CBD, THCA, CBG, etc.)
+- User-reported effects (calm, happy, relaxed, etc.)

+## Novel Analytics (Our Unique IP)
+
+These are analytics **only we can build** due to our unique data:
+
+### 1. Potency-Price Optimization
+
+No one else tracks full cannabinoid profiles. We can answer:
+
+```sql
+-- What's the optimal THC% for each price tier?
+SELECT
+  NTILE(5) OVER (ORDER BY price) as price_tier,
+  AVG(thc_content) as avg_thc,
+  SUM(ABS(quantity_delta)) as units_sold,
+  AVG(daily_velocity) as avg_velocity
+FROM inventory_changes
+WHERE change_type = 'sale' AND thc_content IS NOT NULL
+GROUP BY 1;
+
+-- Value per mg THC - are customers paying for potency?
+SELECT
+  brand_name,
+  AVG(price / NULLIF(thc_content, 0)) as price_per_thc_pct,
+  SUM(revenue) as total_revenue
+FROM inventory_changes
+WHERE change_type = 'sale' AND thc_content > 0
+GROUP BY brand_name
+ORDER BY total_revenue DESC;
+```
+
+**Business value**: Brands can optimize potency targeting. Retailers can price by potency.
+
+### 2. Effect-Driven Product Development
+
+We track user-reported effects (calm, happy, relaxed, euphoric, energetic, etc.)
+
+```sql
+-- Which effect profiles drive highest sales?
+SELECT
+  effects->>'calm' as calm_score,
+  effects->>'happy' as happy_score,
+  SUM(revenue) as total_revenue,
+  AVG(daily_velocity) as avg_velocity
+FROM inventory_changes
+WHERE change_type = 'sale' AND effects IS NOT NULL
+GROUP BY 1, 2
+ORDER BY total_revenue DESC;
+
+-- Effect preferences by time of day
+SELECT
+  EXTRACT(hour FROM detected_at) as hour,
+  AVG((effects->>'calm')::int) as avg_calm_sold,
+  AVG((effects->>'energetic')::int) as avg_energetic_sold
+FROM inventory_changes
+WHERE change_type = 'sale' AND effects IS NOT NULL
+GROUP BY 1;
+```
+
+**Business value**: Brands develop products for specific effects. Morning = energetic, evening = calm.
+
+### 3. Minute-Level Flash Sale Analysis
+
+No one else has per-minute data. We can detect:
+
+```sql
+-- Flash sale effectiveness (sales spike detection)
+SELECT
+  date_trunc('minute', detected_at) as minute,
+  COUNT(*) as transactions,
+  SUM(revenue) as minute_revenue,
+  LAG(SUM(revenue)) OVER (ORDER BY date_trunc('minute', detected_at)) as prev_minute,
+  SUM(revenue) / NULLIF(LAG(SUM(revenue)) OVER (ORDER BY date_trunc('minute', detected_at)), 0) as spike_ratio
+FROM inventory_changes
+WHERE change_type = 'sale'
+GROUP BY 1
+HAVING SUM(revenue) / NULLIF(LAG(SUM(revenue)) OVER (ORDER BY date_trunc('minute', detected_at)), 0) > 2;
+```
+
+**Business value**: Detect when promotions go live. Measure immediate impact.
+
+### 4. Substitution Pattern Analysis
+
+When product A sells out, what do customers buy instead?
+
+```sql
+-- Find substitution patterns after stock-outs
+WITH stockouts AS (
+  SELECT dispensary_id, product_id, brand_name, category, detected_at as stockout_time
+  FROM inventory_changes
+  WHERE quantity_after = 0
+),
+subsequent_sales AS (
+  SELECT ic.*, so.brand_name as stockout_brand, so.product_id as stockout_product
+  FROM inventory_changes ic
+  JOIN stockouts so ON ic.dispensary_id = so.dispensary_id
+    AND ic.category = so.category
+    AND ic.brand_name != so.brand_name
+    AND ic.detected_at BETWEEN so.stockout_time AND so.stockout_time + INTERVAL '4 hours'
+  WHERE ic.change_type = 'sale'
+)
+SELECT
+  stockout_brand,
+  brand_name as substitute_brand,
+  COUNT(*) as substitutions,
+  SUM(revenue) as captured_revenue
+FROM subsequent_sales
+GROUP BY stockout_brand, brand_name
+ORDER BY substitutions DESC;
+```
+
+**Business value**: Identify who steals your sales when you're OOS. Understand brand loyalty.
+
+### 5. Cannabinoid Trend Forecasting
+
+Track shifts in cannabinoid preferences over time:
+
+```sql
+-- THC preference trend over time
+SELECT
+  date_trunc('week', detected_at) as week,
+  AVG(thc_content) FILTER (WHERE change_type = 'sale') as avg_thc_sold,
+  PERCENTILE_CONT(0.9) WITHIN GROUP (ORDER BY thc_content) as p90_thc,
+  SUM(ABS(quantity_delta)) FILTER (WHERE cbg_content > 0) as cbg_units,
+  SUM(ABS(quantity_delta)) FILTER (WHERE thca_content > 25) as high_thca_units
+FROM inventory_changes
+WHERE thc_content IS NOT NULL
+GROUP BY 1
+ORDER BY 1;
+```
+
+**Business value**: Predict demand for high-THC products. Spot emerging cannabinoids (CBG boom).
+
+### 6. Price Elasticity by Product Attribute
+
+How does price sensitivity vary by THC%, category, brand tier?
+
+```sql
+-- Price elasticity by THC tier
+SELECT
+  CASE
+    WHEN thc_content < 15 THEN 'low_thc'
+    WHEN thc_content < 25 THEN 'mid_thc'
+    ELSE 'high_thc'
+  END as thc_tier,
+  CORR(price, ABS(quantity_delta)) as price_volume_correlation,
+  AVG(CASE WHEN is_special THEN ABS(quantity_delta) END) /
+  NULLIF(AVG(CASE WHEN NOT is_special THEN ABS(quantity_delta) END), 0) as special_lift
+FROM inventory_changes
+WHERE change_type = 'sale' AND thc_content IS NOT NULL
+GROUP BY 1;
+```
+
+**Business value**: Set optimal prices by product segment. Know where discounts work.
+
+### 7. Strain Performance Leaderboard
+
+Track which strains sell best across all stores:
+
+```sql
+-- Top performing strains (via product name parsing)
+SELECT
+  REGEXP_REPLACE(product_name, '.*(Indica|Sativa|Hybrid).*', '\1') as strain_type,
+  -- Extract strain name from common patterns
+  SPLIT_PART(product_name, '|', 2) as strain_name,
+  COUNT(DISTINCT dispensary_id) as stores_carrying,
+  SUM(revenue) as total_revenue,
+  SUM(ABS(quantity_delta)) as units_sold
+FROM inventory_changes
+WHERE change_type = 'sale'
+GROUP BY 1, 2
+HAVING COUNT(DISTINCT dispensary_id) > 3
+ORDER BY total_revenue DESC
+LIMIT 50;
+```
+
+**Business value**: Growers know which genetics to cultivate. Buyers know what to stock.
+
+### 8. Promotional Strategy Optimization
+
+BOGO vs % off vs $ off - what works best?
+
+```sql
+-- Analyze special types from specialData (if captured)
+SELECT
+  category,
+  is_special,
+  AVG(ABS(quantity_delta)) as avg_units_per_sale,
+  AVG((price - COALESCE(special_price, price)) / NULLIF(price, 0) * 100) as avg_discount_pct,
+  SUM(revenue) as total_revenue
+FROM inventory_changes
+WHERE change_type = 'sale'
+GROUP BY category, is_special;
+```
+
+**Business value**: Optimize promotional calendar. Know which discount types move product.
+
+### 9. Restock Prediction Model
+
+Predict when stores will run out based on velocity:
+
+```sql
+-- Days until stockout prediction
+SELECT
+  dispensary_id,
+  product_id,
+  product_name,
+  brand_name,
+  option,
+  current_qty,
+  daily_velocity,
+  CASE
+    WHEN daily_velocity > 0 THEN current_qty / daily_velocity
+    ELSE 999
+  END as days_until_stockout
+FROM (
+  SELECT DISTINCT ON (dispensary_id, product_id, option)
+    dispensary_id,
+    product_id,
+    product_name,
+    brand_name,
+    option,
+    quantity_after as current_qty
+  FROM inventory_changes
+  ORDER BY dispensary_id, product_id, option, detected_at DESC
+) current_stock
+JOIN mv_sku_velocity USING (dispensary_id, product_id, option)
+WHERE current_qty > 0 AND daily_velocity > 0
+ORDER BY days_until_stockout ASC;
+```
+
+**Business value**: Proactive reorder alerts. Prevent lost sales.
+
+### 10. Category Cannibalization Detection
+
+Does a new category steal from existing ones?
+
+```sql
+-- Week-over-week category share shift
+WITH weekly_category AS (
+  SELECT
+    date_trunc('week', detected_at) as week,
+    category,
+    SUM(revenue) as category_revenue
+  FROM inventory_changes
+  WHERE change_type = 'sale'
+  GROUP BY 1, 2
+)
+SELECT
+  category,
+  week,
+  category_revenue,
+  category_revenue / SUM(category_revenue) OVER (PARTITION BY week) * 100 as share_pct,
+  category_revenue / NULLIF(LAG(category_revenue) OVER (PARTITION BY category ORDER BY week), 0) - 1 as wow_growth
+FROM weekly_category
+ORDER BY week DESC, category_revenue DESC;
+```
+
+**Business value**: Spot when vapes steal from flower. Understand format shifts.
+
+### 11. Cross-Store Price Arbitrage
+
+Same product, different prices at different stores:
+
+```sql
+-- Price variance for same product across stores
+SELECT
+  product_name,
+  brand_name,
+  option,
+  COUNT(DISTINCT dispensary_id) as store_count,
+  MIN(price) as min_price,
+  MAX(price) as max_price,
+  MAX(price) - MIN(price) as price_spread,
+  STDDEV(price) as price_stddev
+FROM inventory_changes
+WHERE change_type = 'sale'
+GROUP BY product_name, brand_name, option
+HAVING COUNT(DISTINCT dispensary_id) > 3 AND MAX(price) - MIN(price) > 5
+ORDER BY price_spread DESC;
+```
+
+**Business value**: Brands ensure MSRP compliance. Retailers benchmark pricing.
+
+### 12. Time-of-Day × Category Heatmap
+
+When do different categories sell?
+
+```sql
+-- Sales heatmap by hour and category
+SELECT
+  EXTRACT(hour FROM detected_at) as hour,
+  category,
+  SUM(revenue) as revenue,
+  SUM(ABS(quantity_delta)) as units
+FROM inventory_changes
+WHERE change_type = 'sale' AND category IS NOT NULL
+GROUP BY 1, 2
+ORDER BY hour, revenue DESC;
+```
+
+**Business value**: Schedule staff by category demand. Time promotions optimally.
+
+### 13. New Product Launch Velocity Benchmark
+
+How fast should a new product sell to be "successful"?
+
+```sql
+-- Benchmark: velocity in first 7 days vs established products
+SELECT
+  category,
+  CASE
+    WHEN first_seen > NOW() - INTERVAL '7 days' THEN 'new_launch'
+    ELSE 'established'
+  END as product_age,
+  AVG(daily_velocity) as avg_velocity,
+  PERCENTILE_CONT(0.5) WITHIN GROUP (ORDER BY daily_velocity) as median_velocity,
+  PERCENTILE_CONT(0.75) WITHIN GROUP (ORDER BY daily_velocity) as p75_velocity
+FROM mv_new_product_performance
+GROUP BY category, product_age;
+```
+
+**Business value**: Set launch KPIs. Identify winners/losers early.
+
+### 14. Weather Impact Analysis (External Integration)
+
+Correlate sales with weather data:
+
+```sql
+-- (Requires weather data integration)
+-- Do edibles sell more on rainy days?
+SELECT
+  w.condition, -- sunny, rainy, cloudy
+  ic.category,
+  AVG(ic.revenue) as avg_daily_revenue
+FROM inventory_changes ic
+JOIN weather_data w ON DATE(ic.detected_at) = w.date AND ic.state = w.state
+WHERE ic.change_type = 'sale'
+GROUP BY w.condition, ic.category;
+```
+
+**Business value**: Predict demand spikes. Optimize inventory for weather.

+# Payload-Based Sales Intelligence System
+
+## Overview
+
+CannaIQ stores raw product payloads from dispensary platforms (Dutchie, Jane, etc.) in MinIO/Wasabi S3 storage. By comparing payloads over time, we can calculate:
+
+- **Units sold** (quantity decreases)
+- **Revenue** (qty × price, using special pricing when applicable)
+- **New arrivals** (products appearing)
+- **Sold out items** (products disappearing)
+- **Price changes** (regular and special)
+- **Brand performance** (aggregated by brand)
+
+## Data Structure
+
+### Payload Storage
+
+Payloads are stored in MinIO with path pattern:
+```
+payloads/{platform}/{year}/{month}/{day}/store_{id}_{timestamp}.json[.gz]
+```
+
+Example:
+```
+payloads/dutchie/2025/12/17/store_112_t008jb_1765939307492.json
+```
+
+### Key Fields for Sales Calculation
+
+| Field | Location | Description |
+|-------|----------|-------------|
+| `quantity` | `POSMetaData.children[i].quantity` | Current stock for variant |
+| `quantityAvailable` | `POSMetaData.children[i].quantityAvailable` | Available stock |
+| `kioskQuantityAvailable` | `POSMetaData.children[i].kioskQuantityAvailable` | Kiosk-specific stock |
+| `price` | `POSMetaData.children[i].price` or `Prices[i]` | Regular price |
+| `recPrice` | `POSMetaData.children[i].recPrice` | Recreational price |
+| `medPrice` | `POSMetaData.children[i].medPrice` | Medical price |
+| `special` | Product root | Boolean - is product on sale |
+| `recSpecialPrices` | Product root | Array of special prices per variant |
+| `medicalSpecialPrices` | Product root | Array of medical special prices |
+| `Options` | Product root | Array of weight/size strings (e.g., "1/8oz", "1g") |
+
+### POSMetaData.children[i] - Full Structure

+  }]
+}
+```
+
+### Product Structure Example
+
+```json
+{
+  "id": "67d206d0df131282d5ce95a0",
+  "Name": "High West Farms Flower Mylar | Timewreck",
+  "brand": { "name": "High West Farms" },
+  "Options": ["1/2oz"],
+  "Prices": [60],
+  "special": true,
+  "recSpecialPrices": [45],
+  "POSMetaData": {
+    "children": [
+      {
+        "option": "1/2oz",
+        "quantity": 3,
+        "quantityAvailable": 0,
+        "price": 60,
+        "recPrice": 60
+      }
+    ]
+  }
+}
+```
+
+## Sales Calculation Formula
+
+```
+For each SKU variant:
+  qty_sold = before.POSMetaData.children[i].quantity - after.POSMetaData.children[i].quantity
+
+  If qty_sold > 0:
+    price = after.recSpecialPrices[i] if after.special else after.Prices[i]
+    revenue = qty_sold × price
+```
+
+**Key principle**: Use TODAY's price (from the newer payload) because that's what the customer paid.
+
+## Scripts
+
+### 1. Track Quantity Over Time
+`src/scripts/track-qty-over-time.ts`
+
+Shows SKU quantity at each snapshot:
+```
+DR Flower Mylar | AK 1995 (1/8oz)
+Price: $7.98 (special) | Sold: 23 units | Revenue: $183.54
+Qty: Dec 12 11:57 PM: 25 → Dec 13 04:49 AM: 25 → Dec 14 03:34 AM: 22 → Dec 16 07:41 PM: 2
+```
+
+### 2. Calculate Sales Between Payloads
+`src/scripts/calculate-sales.ts`
+
+Compares two payloads and outputs:
+- Total units sold
+- Total revenue
+- Top products by revenue
+- Revenue by brand
+- Special vs regular pricing breakdown
+
+### 3. Diff With Specials
+`src/scripts/diff-with-specials.ts`
+
+Shows inventory changes with special pricing context:
+- New arrivals
+- Sold out / removed
+- Price changes
+- New specials added
+- Specials ended
+- Special price adjustments
+
+## MinIO Access

+
+## Payload Capture Requirements
+
+For accurate sales calculation, payloads MUST include:
+
+1. **`includeEnterpriseSpecials: true`** in GraphQL query variables
+   - Provides `recSpecialPrices` and `specialData`
+
+2. **`POSMetaData` with children array**
+   - Contains per-variant quantity data
+
+3. **Multiple snapshots over time**
+   - More frequent = more granular sales data
+   - Recommended: every 4-6 hours minimum
+
+## Additional Data Available
+
+### Cannabinoids (cannabinoidsV2)
+844/987 products have detailed cannabinoid data:

+
+## Data Flow
+
+### 1. Payload Capture (Every Minute)
+
+```typescript
+interface PayloadCapture {
+  dispensaryId: number;
+  capturedAt: Date;
+  products: DutchieProduct[];
+  payloadHash: string;
+}
+```
+
+### 2. Diff Calculation
+
+```typescript
+interface InventoryChange {
+  dispensaryId: number;
+  productId: string;
+  canonicalId?: string;
+  canonicalSku?: string;
+  productName: string;
+  brandName: string;
+  option: string;
+
+  changeType: 'sale' | 'restock' | 'price_change' | 'new' | 'removed';
+
+  quantityBefore?: number;
+  quantityAfter?: number;
+  quantityDelta?: number;
+
+  price: number;
+  specialPrice?: number;
+  isSpecial: boolean;
+  revenue?: number;  // For sales: abs(quantityDelta) * effectivePrice
+
+  category?: string;
+  subcategory?: string;
+  strainType?: string;
+  thcContent?: number;
+
+  detectedAt: Date;
+  payloadTimestamp: Date;
+}
+```
+
+### 3. Change Detection Logic
+
+```typescript
+function detectChanges(
+  prevPayload: DutchieProduct[],
+  currPayload: DutchieProduct[],
+  dispensaryId: number,
+  timestamp: Date
+): InventoryChange[] {
+  const changes: InventoryChange[] = [];

+  const prevMap = buildVariantMap(prevPayload);
+  const currMap = buildVariantMap(currPayload);
+
+  // Check for sales/restocks (quantity changes)
+  for (const [key, curr] of currMap) {

+
+    if (!prev) {
+      // NEW product
+      changes.push({
+        changeType: 'new',
+        quantityAfter: curr.quantity,
+        ...curr
+      });
+      continue;
+    }
+
+    const qtyDelta = curr.quantity - prev.quantity;
+
+    if (qtyDelta < 0) {
+      // SALE
+      const effectivePrice = curr.isSpecial ? curr.specialPrice : curr.price;
+      changes.push({
+        changeType: 'sale',

+      });

+
+    // Check for price changes (separate from qty)
+    if (prev.price !== curr.price || prev.specialPrice !== curr.specialPrice) {

+        ...prev
+      });
+    }
+  }
+
+  return changes;
+}
+```
+
+## Storage Estimates
+
+### At 1 Payload/Minute
+
+| Metric | 1 Store | 10 Stores | 100 Stores |
+|--------|---------|-----------|------------|
+| **Full Payloads** | | | |
+| Daily | 828 MB | 8.1 GB | 81 GB |
+| Monthly | 24 GB | 242 GB | 2.4 TB |
+| **Diffs Only** | | | |
+| Daily | 1.4 MB | 14 MB | 137 MB |
+| Monthly | 41 MB | 412 MB | 4 GB |
+| **DB Rows/Day** | 7,200 | 72,000 | 720,000 |
+| **DB Rows/Year** | 2.6M | 26M | 263M |
+
+### Recommended Approach
+
+1. **Diffs → PostgreSQL** (queryable, ~4 GB/month for 100 stores)
+2. **Raw Payloads → MinIO** (cold storage, 30-90 day retention)
+3. **Daily Snapshots → PostgreSQL** (point-in-time reconstruction)
+
+## Browser Fingerprinting Strategy
+
+### Why Not Curl
+- Curl has distinctive TLS fingerprint
+- No JavaScript execution
+- Missing browser-specific headers
+- Easily detected and blocked
+
+### Browser-Based Approach
+
+```typescript
+interface BrowserSession {
+  // Puppeteer with stealth plugin
+  browser: Browser;
+  page: Page;
+
+  // Evomi residential proxy (rotates per session)
+  proxy: {
+    host: string;
+    port: number;
+    username: string;
+    password: string;
+    geo: string;  // State targeting
+  };
+
+  // Randomized fingerprint
+  fingerprint: {
+    userAgent: string;
+    viewport: { width: number; height: number };
+    platform: 'Windows' | 'MacOS' | 'Linux';
+    deviceType: 'desktop' | 'mobile' | 'tablet';
+  };
+
+  // Session management
+  createdAt: Date;
+  requestCount: number;
+  maxRequests: number;  // Rotate after N requests
+  maxAge: number;       // Rotate after N minutes
+}
+```

+# Using the Docker Registry Cache
+
+To avoid Docker Hub rate limits, use our registry at `registry.spdy.io` (HTTPS) or `10.100.9.70:5000` (HTTP internal).
+
+## For Woodpecker CI (Kaniko builds)
+
+In your `.woodpecker.yml`, use these Kaniko flags:
+
+```yaml
+docker-build:
+  image: gcr.io/kaniko-project/executor:debug
+  commands:
+    - /kaniko/executor
+      --context=/woodpecker/src/...
+      --dockerfile=Dockerfile
+      --destination=10.100.9.70:5000/your-image:tag
+      --registry-mirror=10.100.9.70:5000
+      --insecure-registry=10.100.9.70:5000
+      --cache=true
+      --cache-repo=10.100.9.70:5000/your-image/cache
+      --cache-ttl=168h
+```
+
+**Key points:**
+- `--registry-mirror=10.100.9.70:5000` - Pulls base images from local cache
+- `--insecure-registry=10.100.9.70:5000` - Allows HTTP (not HTTPS)
+- `--cache=true` + `--cache-repo=...` - Caches build layers locally
+
+## Available Base Images
+
+The local registry has these cached:
+
+| Image | Tags |
+|-------|------|
+| `node` | `20-slim`, `22-slim`, `22-alpine`, `20-alpine` |
+| `alpine` | `latest` |
+| `nginx` | `alpine` |
+| `bitnami/kubectl` | `latest` |
+| `gcr.io/kaniko-project/executor` | `debug` |
+
+Need a different image? Add it to the cache using crane:
+
+```bash

+
+## Which Registry URL to Use
+
+| Context | URL | Why |
+|---------|-----|-----|
+| Kaniko builds (CI) | `10.100.9.70:5000` | Internal HTTP, faster |
+| kubectl set image | `registry.spdy.io` | HTTPS, k8s nodes can pull |
+| Checking images | Either works | Same backend |
+
+## DO NOT USE
+
+- ~~`--registry-mirror=mirror.gcr.io`~~ - Rate limited by Docker Hub
+- ~~Direct pulls from `docker.io`~~ - Rate limited (100 pulls/6hr anonymous)
+- ~~`10.100.9.70:5000` in kubectl commands~~ - k8s nodes require HTTPS
+
+## Checking Cached Images
+
+List all cached images:
+```bash
+curl -s http://10.100.9.70:5000/v2/_catalog | jq
+```
+
+List tags for a specific image:
+```bash
+curl -s http://10.100.9.70:5000/v2/library/node/tags/list | jq
+```
+
+## Troubleshooting
+
+### "no such host" or DNS errors
+The CI runner can't reach the registry mirror. Make sure you're using `10.100.9.70:5000`, not `mirror.gcr.io`.
+
+### "manifest unknown"
+The image/tag isn't cached. Add it using the crane command above.
+
+### HTTP vs HTTPS errors
+Always use `--insecure-registry=10.100.9.70:5000` - the local registry uses HTTP.
