+name: testing-ecommerce-features
+description: Test ecommerce features (cart, catalog, orders, social commerce, promotions, agent store) end-to-end. Use when verifying middleware integration, persistence patterns, mobile parity, or payment flow changes in ecommerce routers.
+---
+
+# Testing Ecommerce Features
+
+## Overview
+The ecommerce layer spans 6 TypeScript routers, 1 Go service, 1 Rust service, 1 Python service, 5 Flutter screens, and 5 React Native screens. Each mutation must integrate with the middleware stack and persist to PostgreSQL.
+
+## Environment Setup
+- **Repo:** `munisp/agentbanking`
+- **Branch:** `production-hardened` is the main development branch
+- **No live server** in most sessions — no DATABASE_URL, Redis, Kafka env vars
+- **TypeScript check:** `npx tsc --noEmit` (pre-existing errors in react-i18next/@dnd-kit are expected)
+- **Test suite:** `npx vitest run` (8 pre-existing failures: db-performance x4, e2e x1, sprint46 x1, sprint95 x1, middleware-runtime x2)
+- **Package manager:** pnpm
+
+## Devin Secrets Needed
+- `DATABASE_URL` — PostgreSQL connection string (not currently available; testing is shell-based)
+- No other secrets required for structural validation
+
+## Key Files
+- **TS Routers:** `server/routers/ecommerceOrders.ts`, `ecommerceCatalog.ts`, `ecommerceCart.ts`, `agentStore.ts`, `promotions.ts`, `socialCommerceGateway.ts`
+- **Kafka topics:** `server/kafkaClient.ts` (KafkaTopic union type)
+- **Rust cart:** `server/ecommerce-cart-rust/src/{main,cart,checkout,offline}.rs`
+- **Go catalog:** `server/ecommerce-catalog-go/handlers/handlers.go`
+- **Python intelligence:** `server/ecommerce-intelligence-py/main.py`
+- **Migration:** `drizzle/drizzle/0044_ecommerce_enhancements.sql`
+- **Flutter screens:** `mobile-flutter/mobile-flutter/lib/screens/ecommerce_*.dart`
+- **RN screens:** `mobile-rn/mobile-rn/src/screens/Ecommerce*.tsx`
+- **Middleware clients:** `server/tbClient.ts`, `server/fluvio.ts`, `server/lakehouse.ts`, `server/redisClient.ts`, `server/middleware/middlewareConnectors.ts`
+
+## Testing Approach (Shell-Based Structural Validation)
+
+### 1. TypeScript Compilation
+```bash
+npx tsc --noEmit 2>&1 | grep "error TS" | grep -E "ecommerceOrders|ecommerceCatalog|ecommerceCart|agentStore|promotions|socialCommerce|kafkaClient"
+```
+**Expected:** Zero output (0 errors in modified ecommerce files)
+
+### 2. Middleware Active Calls (NOT Dead Code)
+This is the MOST IMPORTANT test. PR #46/#48 had middleware helpers defined but never called. Check that each router has active calls (total - 1 definition >= 3):
+```bash
+for f in ecommerceCatalog ecommerceCart agentStore promotions socialCommerceGateway ecommerceOrders; do
+  FILE="server/routers/$f.ts"
+  TOTAL=$(grep -c "publish.*Middleware(" "$FILE")
+  ACTIVE=$((TOTAL - 1))
+  echo "$f: $ACTIVE active calls $([ $ACTIVE -ge 3 ] && echo PASS || echo FAIL)"
+done
+```
+
+### 3. Fail-Open Pattern
+Extract each router's middleware helper body and verify .catch() count >= middleware call count:
+```bash
+for f in ecommerceCatalog ecommerceCart agentStore promotions socialCommerceGateway ecommerceOrders; do
+  FILE="server/routers/$f.ts"
+  HELPER_BODY=$(sed -n '/async function publish.*Middleware/,/^}/p' "$FILE")
+  MW=$(echo "$HELPER_BODY" | grep -c "publishEvent\|tbCreateTransfer\|publishTxToFluvio\|dapr.publishEvent\|ingestToLakehouse\|cacheSet")
+  CATCH=$(echo "$HELPER_BODY" | grep -c '\.catch(')
+  echo "$f: $MW calls, $CATCH catches — $([ $CATCH -ge $MW ] && echo PASS || echo FAIL)"
+done
+```
+
+### 4. Rust Cart Persistence
+```bash
+# DashMap must be fully eliminated
+grep -rn "DashMap\|dashmap" server/ecommerce-cart-rust/src/
+# Should return 0 matches
+
+# PostgreSQL must be present
+grep -c "PgPool" server/ecommerce-cart-rust/src/main.rs   # >= 3
+grep -c "sqlx::query" server/ecommerce-cart-rust/src/cart.rs  # >= 10
+grep -c "sqlx::query" server/ecommerce-cart-rust/src/checkout.rs  # >= 5
+grep -c "sqlx::query" server/ecommerce-cart-rust/src/offline.rs  # >= 5
+```
+
+### 5. KafkaTopic Union
+All topics used in publishEvent calls must exist in the KafkaTopic union in `server/kafkaClient.ts`:
+```bash
+USED=$(grep -ohP 'publishEvent\("([^"]+)"' server/routers/ecommerce*.ts server/routers/agentStore.ts server/routers/promotions.ts server/routers/socialCommerceGateway.ts | sed 's/publishEvent("//;s/"//' | sort -u)
+for topic in $USED; do
+  [ "$topic" = "pubsub" ] && continue
+  grep -q "\"$topic\"" server/kafkaClient.ts && echo "PASS: $topic" || echo "FAIL: $topic"
+done
+```
+
+### 6. TigerBeetle Type Safety
+socialCommerceGateway previously used BigInt() which mismatched TBTransferRequest (expects string/number):
+```bash
+grep -c "BigInt" server/routers/socialCommerceGateway.ts
+# Must be 0
+```
+
+### 7. ecommerceOrders Key Features
+```bash
+# New endpoints exist
+for ep in recoverAbandonedCarts releaseExpiredReservations checkoutFlashSale getDeliveryTracking updateDeliveryTracking convertOrderCurrency; do
+  grep -q "$ep:" server/routers/ecommerceOrders.ts && echo "PASS: $ep" || echo "FAIL: $ep"
+done
+
+# Payment verification wired to createFromCart
+grep -A 200 "createFromCart:" server/routers/ecommerceOrders.ts | head -200 | grep -c "verifyPaymentGateway"  # >= 1
+
+# Notifications wired to updateStatus
+grep -A 200 "updateStatus:" server/routers/ecommerceOrders.ts | head -200 | grep -c "sendOrderNotification"  # >= 1
+
+# Flash sale FOR UPDATE locking
+grep -A 50 "checkoutFlashSale:" server/routers/ecommerceOrders.ts | head -50 | grep -c "FOR UPDATE"  # >= 1
+```
+
+### 8. Go Catalog Events
+```bash
+grep -c "publishCatalogEvent.*inventory" server/ecommerce-catalog-go/handlers/handlers.go
+# >= 3 (reserved, released, deducted)
+```
+
+### 9. Python Innovation Endpoints
+```bash
+for ep in "checkout-adjust" "offline-bundle" "barcode-to-cart"; do
+  grep -q "$ep" server/ecommerce-intelligence-py/main.py && echo "PASS: $ep" || echo "FAIL: $ep"
+done
+```
+
+### 10. Migration DDL
+```bash
+TABLE_COUNT=$(grep -ci "CREATE TABLE" drizzle/drizzle/0044_ecommerce_enhancements.sql)
+INDEX_COUNT=$(grep -ci "CREATE INDEX" drizzle/drizzle/0044_ecommerce_enhancements.sql)
+echo "Tables: $TABLE_COUNT (expect 12), Indexes: $INDEX_COUNT (expect 11)"
+```
+
+### 11. Mobile Screens (Not Scaffolds)
+Scaffold screens had 0 API calls and ~131/163 lines. Real screens should have >= 2 API calls:
+```bash
+for f in ecommerce_shopping_cart_screen ecommerce_product_catalog_screen ecommerce_checkout_screen; do
+  FILE="mobile-flutter/mobile-flutter/lib/screens/$f.dart"
+  API=$(grep -c "ApiService\|\.get(\|\.post(" "$FILE")
+  echo "Flutter $f: $API API calls (>=2 = real)"
+done
+for f in EcommerceShoppingCartScreen EcommerceProductCatalogScreen EcommerceCheckoutScreen; do
+  FILE="mobile-rn/mobile-rn/src/screens/$f.tsx"
+  API=$(grep -c "apiService\.\|\.get(\|\.post(" "$FILE")
+  echo "RN $f: $API API calls (>=2 = real)"
+done
+```
+
+## Common Issues
+
+### Dead middleware code (PR #46/#48 bug)
+The `publishXxxMiddleware()` helper can be defined but never called from mutation handlers. Always verify active call count, not just that the function exists. Count total references minus 1 (the definition).
+
+### BigInt vs String in TigerBeetle
+`TBTransferRequest` expects `debitAccountId: string` and `creditAccountId: string`. Using `BigInt()` causes TS2322. Use `String()` instead.
+
+### agentStore input field names
+- `createDeliveryZone` uses `input.zoneName` (not `input.name`)
+- `createPaymentSplit` uses `input.orderTotal` (not `input.orderAmount`)
+Check Zod schema before referencing input fields.
+
+### Multi-line middleware calls
+`tbCreateTransfer({...}).catch()` spans 4-5 lines. Single-line grep for `.catch()` will miss it. Use `sed` to extract the helper body first, then count within the block.
+
+### Rust DashMap → PgPool migration
+After migration, check both directions:
+1. **Negative:** 0 DashMap/dashmap references in src/
+2. **Positive:** PgPool in AppState + sqlx::query calls in every handler
+
+### Pre-existing failures
+These are known and unrelated to ecommerce:
+1. `db-performance.test.ts` x4 (needs PgBouncer)
+2. `e2e/critical-flows.spec.ts` x1 (needs live server)
+3. `sprint46.test.ts` x1 (currency count)
+4. `sprint95.test.ts` x1 (router count hardcoded)
+5. `middleware-integration-runtime.test.ts` x2 (needs live Redis)
+
+## Recording
+No recording needed — all validation is shell-based. Only record if testing involves browser UI interactions (e.g., testing the PWA storefront or checkout flow with a live server).
