Implement Integration Test Plan

Execute the integration test plan developed in Q1 by implementing the identified test cases as automated integration tests. Create test scenarios covering end-to-end transaction flows from client submission through endorsement, ordering, and commit. Implement tests for MVCC conflict detection and retry logic, synchronization correctness across endorsers and gateway, Ethereum RPC API compliance with standard client libraries, and various smart contract deployment and execution patterns. Organize tests by deployment target (local, Fabric, Fabric-X) and ensure they can run in CI/CD pipelines. Document test setup requirements, expected outcomes, and troubleshooting guidance for test failures.

**Quarter:** Q2

Start by locating and reading the Q1 integration test plan referenced in the issue. Map its identified cases across local, Fabric, and Fabric-X deployments, then determine how the repository runs integration tests in CI/CD. Done means the listed transaction, conflict, synchronization, RPC, and smart-contract scenarios are automated, organized by target, and documented with setup, outcomes, and troubleshooting guidance.
