🔄 Migration Steps Remaining

1. Finish creating all domains
2. Update package.json with new exports
3. Update tsconfig paths
4. Create migration script for imports (optional)
5. Update sample imports in BFF (1-2 files as examples)
6. Update sample imports in Portal (1-2 files as examples)
7. Build and verify compilation
8. Update documentation

🎯 New Import Patterns (Examples)

Current (Old)

import { Invoice } from "@customer-portal/contracts/billing";
import { invoiceSchema } from "@customer-portal/schemas/billing";
import { transformWhmcsInvoice } from "@customer-portal/integrations-whmcs/mappers";

New (Domain-First)

import { Invoice, invoiceSchema, INVOICE_STATUS } from "@customer-portal/domain/billing";
import { transformWhmcsInvoice } from "@customer-portal/domain/billing/providers/whmcs/mapper";

---

✨ Benefits Achieved

1. ✅ Domain-centric organization
2. ✅ Co-located contracts + schemas
3. ✅ Provider isolation (no leaking)
4. ✅ Single package (@customer-portal/domain)
5. ✅ Scalable provider pattern

Next Steps: Complete orders, catalog, common, toolkit, then package configuration.
