Subject: [PATCH 02/33] feature/(api): add http4s support for v5.0.0 API routes

Introduce new Http4s500 module providing v5.0.0 API endpoints alongside existing v7.0.0 routes.
Update Http4sServer to serve both API versions by combining routes with fallback logic.
Modify ResourceDocMiddleware to extract API version from request path for proper call context.
Add comprehensive test suites for v5.0.0 routes and contract parity verification.

Subject: [PATCH 03/33] feature/(v5.0.0): add single bank endpoint to http4s
 routes

Implement GET /banks/{BANK_ID} endpoint in the http4s v5.0.0 routes, returning bank details in JSON format. This provides parity with the existing Lift-based API and enables direct http4s client access to individual bank resources.

Add corresponding test scenarios to verify the endpoint functionality and ensure response consistency between http4s and Lift implementations.

Subject: [PATCH 05/33] feature/(http4s): add proxy to lift for parity testing

Add a proxy route in Http4s500 to forward unmatched requests to the legacy Lift framework, enabling contract parity testing between the two implementations. This allows new http4s endpoints to be tested against existing Lift behavior.

Update V500ContractParityTest to include a test for the private accounts endpoint, verifying both implementations return consistent responses. Simplify assertion syntax from `should not be empty` to `isDefined shouldBe true` for clarity.

Subject: [PATCH 06/33] feature/(http4s): enhance request handling and response
 mapping

Refactor the Http4s500 module to improve request handling by introducing a new method for building Lift requests and enhancing the response mapping from Lift to Http4s. This includes the addition of correlation header checks in the V500ContractParityTest to ensure consistent response behavior between Http4s and Lift implementations.

The changes aim to streamline the integration between the two frameworks, facilitating better contract parity testing and improving overall code clarity.

Subject: [PATCH 07/33] feature/(http4s): refactor and integrate
 Http4sLiftBridge for improved request handling

Remove the legacy Http4sBoot class and integrate the new Http4sLiftBridge to enhance request handling and response mapping between Http4s and Lift frameworks. This update includes the addition of standard headers in responses and improves the overall structure of the Http4s server.

New tests have been added to ensure contract parity between the Http4s and Lift implementations, focusing on consistent response behavior across different API versions.

Subject: [PATCH 08/33] Refactor/ test descriptions to use 'liftweb'
 terminology

Update feature descriptions and failure messages in Http4sLiftBridgeParityTest and V500ContractParityTest to consistently refer to 'liftweb' instead of 'Lift'. This change enhances clarity and aligns with the naming conventions used throughout the codebase. Additionally, update comments in MessageDocsJsonSchemaTest for consistency in terminology.

Subject: [PATCH 09/33] Enhance Http4sLiftBridgeParityTest with DirectLogin
 scenarios

Add test user and consumer setup in beforeAll for DirectLogin testing. Introduce new scenarios to validate DirectLogin behavior with and without authentication headers, ensuring consistent response codes and token presence across Http4s and Lift implementations. This improves test coverage and aligns with the ongoing efforts for contract parity.

Subject: [PATCH 11/33] Refactor/ API version handling in ApiCollector and
 related files

Updated the ApiCollector implementations across multiple API versions to replace the deprecated ScannedApiVersion with the new ApiVersion utility. This change enhances consistency and maintainability in the API versioning approach. The affected files include ApiCollector.scala for AU, Bahrain, Polish, STET, and UK Open Banking APIs, as well as the ApiVersion.scala file where new constants were defined for these versions.

- Add comprehensive system views CRUD operations parity test between Lift and Http4s
- Import required dependencies for view creation, entitlements, and JSON serialization
- Add entitlements for system view operations (create, read, update, delete)
- Implement create operation test with request/response parity validation
- Implement get operation test to verify view retrieval consistency
- Implement update operation test with modified view attributes
- Implement get-after-update test to verify persistence of changes
- Implement delete operation test with account access cleanup
- Implement get-after-delete test to verify deletion across both frameworks
- Validate correlation IDs and response status codes for all operations
- Ensure JSON response structure parity between Lift and Http4s implementations

Subject: [PATCH 13/33] refactor/(http4s): enhance Http4sLiftBridge debugging
 and test initialization

- Add comprehensive debug logging throughout Http4sLiftBridge dispatch flow to track request handling and handler resolution
- Log stateful scope state, handler availability checks, and response types for better troubleshooting
- Add detailed request metadata logging (content-type, auth headers, body size, path information) in buildLiftReq
- Move http4sRoutes initialization to beforeAll() to ensure Lift is fully initialized before bridge setup
- Add afterAll() cleanup method to remove test data (ViewDefinition and AccountAccess records)
- Fix header and body ordering in toHttp4sRequest to ensure headers are set after body to prevent defaults from overriding
- Add explanatory comments documenting known limitation of bridge running in separate LiftRules instance from Jetty server
- Improve request construction to properly handle Content-Type and other headers in http4s requests

Subject: [PATCH 14/33] test/(http4s): add response conversion tests and
 enhance bridge debugging

- Add Http4sResponseConversionTest with comprehensive test coverage for Lift to HTTP4S response conversion
- Test all response types: InMemoryResponse, StreamingResponse, OutputStreamResponse, BasicResponse
- Validate HTTP status codes, headers, and body preservation across response types
- Test edge cases: empty responses, large payloads (>1MB), UTF-8 characters, error status codes
- Test streaming responses with callbacks and output stream handling
- Enhance Http4sLiftWebBridge debugging with body preview (first 200 bytes) and request JSON/body logging
- Improve observability for request/response flow debugging and troubleshooting
- Validates Requirements 2.4 (Task 2.5) for response conversion parity

Subject: [PATCH 15/33] test/(http4s): enhance Http4sCallContextBuilder and add
 round-trip property tests

- Refactor Http4sCallContextBuilderTest with improved header extraction test scenarios
- Add comprehensive header handling tests including single values, multiple values, and special characters
- Enhance Authorization header extraction and validation tests
- Add Http4sResponseConversionTest with response mapping and conversion validation
- Create Http4sLiftRoundTripPropertyTest for HTTP4S to Lift Req conversion property-based testing
- Improve test documentation and validation requirements traceability
- Simplify imports and remove unused dependencies for cleaner test code
- Validates Requirements 2.2 for header parameter extraction and query parameter handling

+ * 
+ * For any valid API request (any endpoint, any API version, any authentication method, 
+ * any request parameters), when processed through the HTTP4S-only backend, the response 
+ * (status code, headers, and body) should be byte-for-byte identical to the response 
+ * from the Lift-only implementation.
+ * 
+ * This is the ultimate correctness property for the migration. Byte-for-byte identity 
+ * guarantees that all functionality, error handling, data formats, JSON structures, 
+ * status codes, and pagination formats are preserved.
+ * 
+ * Testing Approach:
+ * - Generate random requests across all API versions and endpoints
+ * - Execute same request through both Lift-only and HTTP4S-only backends
+ * - Compare responses byte-by-byte including status, headers, and body
+ * - Test with valid requests, invalid requests, authentication failures, and edge cases
+ * - Include all international API standards
+ * - Minimum 100 iterations per test

Subject: [PATCH 16/33] test/(http4s): add property-based tests for request and
 response conversion

- Add Http4sRequestConversionPropertyTest with 100+ iteration property tests
- Add Http4sResponseConversionPropertyTest with comprehensive response validation
- Implement random data generators for HTTP methods, URIs, headers, and bodies
- Test HTTP method preservation across random request variations
- Test URI path preservation with various path segments and encodings
- Test query parameter preservation with multiple values and special characters
- Test header preservation including custom headers and edge cases
- Test request body preservation with empty, JSON, and special character payloads
- Test response status code preservation and mapping
- Test response header preservation and accessibility
- Test response body preservation with various content types
- Validate edge cases: empty bodies, special characters, large payloads, unusual headers
- Ensure bridge correctly implements HTTPRequest interface per Requirements 2.2
- Minimum 100 iterations per test scenario for robust property validation

+ * Property Test: Request Conversion Completeness
+ * 
+ * **Validates: Requirements 2.2**
+ * 
+ * For any HTTP4S request, when converted to a Lift Req object by the bridge, 
+ * all request information (HTTP method, URI path, query parameters, headers, 
+ * body content, remote address) should be preserved and accessible through 
+ * the Lift Req interface.
+ * 
+ * The bridge must not lose any request information during conversion. Any missing 
+ * data could cause endpoints to behave incorrectly. This property ensures the 
+ * bridge correctly implements the HTTPRequest interface.
+ * 
+ * Testing Approach:
+ * - Generate random HTTP4S requests with various combinations of headers, params, and body
+ * - Convert to Lift Req through bridge
+ * - Verify all original request data is accessible through Lift Req methods
+ * - Test edge cases: empty bodies, special characters, large payloads, unusual headers
+ * - Minimum 100 iterations per test

+/**
+ * Property Test: Response Conversion Completeness
+ * 
+ * **Property 3: Response Conversion Completeness**
+ * **Validates: Requirements 2.4**
+ * 
+ * For any Lift response type (InMemoryResponse, StreamingResponse, OutputStreamResponse, 
+ * BasicResponse), when converted to HTTP4S response by the bridge, all response data 
+ * (status code, headers, body content, cookies) should be preserved in the HTTP4S response.
+ * 
+ * The bridge must correctly convert all Lift response types to HTTP4S responses without 
+ * data loss. Different response types have different conversion logic that must all be correct.
+ * 
+ * Testing Approach:
+ * - Generate random Lift responses of each type
+ * - Convert through bridge to HTTP4S response
+ * - Verify all response data is preserved
+ * - Test streaming responses, output stream responses, and in-memory responses
+ * - Verify callbacks and cleanup functions are invoked correctly
+ * - Minimum 100 iterations per test

Subject: [PATCH 18/33] refactor/(run_all_tests): improve test class extraction
 from failure logs

- Replace unreliable grep pattern matching with line-number-based approach
- Find most recent test class name before each failure occurrence
- Use awk to filter test class lines that appear before failure markers
- Improve accuracy of test class identification in complex log outputs
- Maintain backward compatibility with existing test file discovery logic
- This change addresses edge cases where multiple test classes appear in logs before failures

Subject: [PATCH 20/33] refactor/(http4s): enhance error handling and request
 conversion for bridge parity

- Replace NotFoundResponse with JSON error responses in Http4sLiftWebBridge for consistent error formatting
- Improve Content-Type header extraction with fallback to header parameters when contentType is unavailable
- Fix query parameter extraction to use parsed queryParams instead of raw URI query parsing
- Add wrappedRoutesV500ServicesWithJsonNotFound for standalone JSON 404 responses
- Add wrappedRoutesV500ServicesWithBridge for production-like fallback behavior to Lift bridge
- Fix multi-value query parameter handling in Http4sRequestConversionPropertyTest by adding all values at once
- Update authenticatedEndpoints to use path segments instead of string literals to avoid URL encoding issues
- Enhance logging messages to indicate JSON 404 responses are being returned
- These changes improve parity between Http4s and Lift implementations and provide better error diagnostics

Subject: [PATCH 23/33] test/(http4sbridge): add Http4sTestServer singleton and
 integration tests

- Add Http4sTestServer singleton for shared HTTP4S test server across test classes
- Create Http4sServerIntegrationTest for real end-to-end HTTP4S server testing
- Move Http4sLiftBridgeParityTest to http4sbridge package for better organization
- Move Http4sLiftRoundTripPropertyTest to http4sbridge package for consistency
- Implement lazy initialization pattern matching TestServer (Jetty/Lift) behavior
- Add automatic server startup on first access and shutdown hook for cleanup
- Enable real HTTP requests over network to test complete server stack including middleware

Subject: [PATCH 24/33] refactor/(http4s): extract shared httpApp configuration
 to Http4sApp

- Extract HTTP4S application configuration into new Http4sApp singleton object
- Remove duplicate route building logic from Http4sServer and Http4sTestServer
- Update Http4sServer to use Http4sApp.httpApp for production server
- Update Http4sTestServer to use Http4sApp.httpApp for test server
- Ensure production and test servers use identical routing configuration
- Eliminate code duplication and establish single source of truth for HTTP4S routes
- Add comprehensive documentation explaining priority-based routing and shared configuration

Subject: [PATCH 26/33] refactor/(http4s): add API version matching to resource
 doc resolution

- Extract API version from request path to enable version-specific routing
- Add apiVersion comparison in ResourceDocMatcher to match docs by version
- Refactor Http4sTestServer logger initialization to use explicit Logger instance
- Remove pending markers from integration tests now that version matching is fixed
- Enable previously failing route matching tests for v5.0.0 and v7.0.0 endpoints
- Fixes 404 errors caused by missing API version validation in resource doc lookup

Subject: [PATCH 29/33] test/(Http4sLiftBridgeParityTest): migrate to
 network-based Http4sTestServer

- Replace in-process bridge initialization with Http4sTestServer singleton reference
- Switch from http4s Request/Response types to dispatch library for HTTP calls
- Implement makeHttp4sGetRequest and makeHttp4sPostRequest using dispatch for network requests
- Update request/response handling to work with HTTP status codes and header maps
- Refactor assertCorrelationId to work with Map[String, String] instead of http4s Headers
- Add comprehensive documentation explaining the test's purpose and architecture
- Remove LiftRules inconsistency workarounds by testing against real HTTP4S server
- Update imports to use dispatch, scala concurrent utilities, and remove http4s internals
- This change ensures parity testing matches production behavior by testing over the network

Subject: [PATCH 30/33] test/(Http4s700RoutesTest): migrate to network-based
 Http4sTestServer

- Replace direct Http4s route invocation with Http4sTestServer singleton for full integration testing
- Remove cats.effect.IO and org.http4s direct dependencies, use dispatch HTTP client instead
- Update request construction from Http4s Request[IO] to dispatch URL-based requests
- Replace Status code comparisons with integer status codes (e.g., Status.Ok to 200)
- Simplify header handling using Map-based approach with DirectLogin token injection
- Add comprehensive class documentation explaining integration test approach
- Refactor runAndParseJson and withDirectLoginToken helpers into single makeHttpRequest function
- Add proper error handling for HTTP request execution with timeout support
- Ensure all test scenarios use real HTTP requests through network stack for complete parity testing

Subject: [PATCH 31/33] test/(http4sbridge): add property-based tests for Lift
 dispatch mechanism

- Add Http4sLiftBridgePropertyTest with comprehensive property-based test suite
- Implement Property 6 validation for Lift dispatch mechanism integration
- Add test scenarios for public endpoint response validity across 100 iterations
- Add handler priority consistency verification across multiple requests
- Add 404 error handling validation for missing endpoints
- Add authentication failure response consistency checks
- Implement HTTP GET and POST request helpers with header support
- Add correlation ID assertion utility for response validation
- Include test data generators for API versions and endpoint paths
- Validates requirements 1.3, 2.3, and 2.5 for HTTP4S-Lift bridge integration
- Ensures 95% success rate threshold for public endpoint availability

Subject: [PATCH 32/33] refactor/(http4s): make Http4sLiftSession thread-safe
 with ConcurrentHashMap

- Replace mutable.Map with ConcurrentHashMap for thread-safe attribute storage
- Add @volatile annotation to maxInactive field for safe concurrent access
- Update setAttribute to use put() method for consistency with ConcurrentHashMap API
- Update attribute getter to use get() method instead of getOrElse()
- Improve thread safety of session attribute operations in multi-threaded environment

Subject: [PATCH 33/33] test/(http4sbridge): add property-based tests for
 session/context adapter

- Add Property 7.1: Concurrent requests maintain session/context thread-safety with 10 concurrent threads per iteration
- Add Property 7.2: Session lifecycle management across sequential requests with proper correlation ID validation
- Add Property 7.3: Request adapter HTTP metadata correctness across multiple API versions and paths
- Add Property 7.4: Context operations correctness under load with rapid sequential requests
- Verify thread-safety using ConcurrentLinkedQueue and CountDownLatch for synchronization
- Validate correlation IDs and response headers in all scenarios
- Ensure proper error handling and resource cleanup in concurrent test scenarios
