+# Architecture
+
+## Overview
+
+`omnipay-nabtransact` remains an Omnipay gateway package and keeps full Omnipay request/response compatibility.
+
+This modernization adds a transport layer so the package can run with:
+
+- Omnipay HTTP client (default, backward compatible)
+- Native cURL transport (framework-agnostic alternative)
+- Custom user transport via contract
+
+## Design Goals
+
+- Preserve Omnipay API surface and existing integrations.
+- Keep non-breaking behavior for request classes and gateway methods.
+- Improve reliability and testability through explicit transport contracts.
+- Keep dependencies minimal.
+
+## Project Map
+
+```text
+src/
+  DirectPostGateway.php
+  SecureXMLGateway.php
+  HostedPaymentGateway.php
+  UnionPayGateway.php
+
+  Message/
+    *Request.php
+    *Response.php
+
+  Transport/
+    TransportInterface.php
+    TransportResponse.php
+    OmnipayHttpClientTransport.php
+    CurlTransport.php
+
+  Enums/
+    TransactionType.php
+```
+
+## Runtime Flows
+
+### 1) SecureXML requests
+
+1. Gateway creates request through Omnipay (`authorize/purchase/capture/refund/echoTest`).
+2. Request builds XML payload.
+3. Request resolves transport in this order:
+   - explicit request transport (`setTransport()`)
+   - Omnipay adapter transport (default)
+4. Response XML is mapped to `SecureXMLResponse`.
+
+### 2) DirectPost / UnionPay
+
+- Redirect-based requests remain unchanged.
+- Fingerprint verification stays compatible.
+- Backward-compat typo alias (`vefiyFingerPrint`) remains supported.
+- DirectPost supports purchase, authorize, complete callbacks, store-only flow, and additive server-to-server operations (`capture`, `refund`, `void`).
+- EMV 3DS order management is exposed via `createEMV3DSOrder()`.
+
+### 3) Hosted Payment
+
+- Redirect form flow remains unchanged.
+- Environment endpoint selection now aligns correctly with `testMode`.
+
+## Extension Points
+
+- Implement `TransportInterface` for custom HTTP stacks.
+- Inject custom transport per request via `setTransport($transport)`.
+
+## Backward Compatibility
+
+- Omnipay gateway class names and behavior remain intact.
+- Existing request/response classes remain available.
+- Deprecated typo method remains callable.
+
+## Testing Strategy
+
+- Request/response behavior tests for existing Omnipay flows.
+- Dedicated tests for transport injection and endpoint correctness.
+- Fingerprint verification coverage (success/failure).

+## Framework-Agnostic Transport Option
+
+Omnipay support remains the default behavior. SecureXML requests can now also use a framework-agnostic cURL transport:
+
+```php
+use Omnipay\NABTransact\Transport\CurlTransport;
+
+$request = $gateway->purchase([
+    'amount' => '10.00',
+    'transactionId' => 'ORDER-1000',
+    'card' => $card,
+]);
+
+$request->setTransport(new CurlTransport());
+$response = $request->send();
+```
+
+DirectPost server-to-server operations (`capture`, `refund`, `void`, `createEMV3DSOrder`) can use the same transport injection pattern.
+
+See `ARCHITECTURE.md` for design details and extension points.
+
+## NAB Feature Coverage
+
+Core payment features are mapped in `docs/feature-matrix.md` with request/response classes and test coverage.
+For a contributor-friendly package map, see `docs/features-implemented-tree.md`.
+This package targets payment-processing API coverage and does not include NAB admin/reporting portal features.
