+# Inventory Module — Manual Review Checklist
+
+High-risk module: stock/inventory changes require human confirmation.
+
+- [ ] Stock decrement is atomic (conditional UPDATE, not read-then-write)
+- [ ] Oversell prevented: `UPDATE ... SET qty = qty - ? WHERE qty >= ?`
+- [ ] Reservation vs. deduction semantics are consistent
+- [ ] Concurrent orders cannot both reserve the last unit
+- [ ] Restock/return increments handled correctly
+- [ ] Inventory events are idempotent (retry-safe)
+- [ ] Async stock updates propagate to downstream (warehouse, carts) safely
