Verify Cross-Origin Resource Sharing (CORS) Bounds for Production

• Category: Backend: Axum API & DB Optimization
• Task ID: BE-API-089

Description

This issue is dedicated to the technical design, implementation, and rigorous auditing of 'Verify Cross-Origin Resource Sharing (CORS) Bounds for Production' inside the Lance marketplace ecosystem, specifically focusing on the Backend: Axum API & DB Optimization component. Working within the Axum rust backend framework, you must implement efficient routing middleware, handle asynchronous task execution with robust safety bounds, and ensure proper tracing instrumentations are configured for full production observability. Ensure that your implementation strictly adheres to the project's architectural guidelines, features self-documenting code with comprehensive inline annotations, and provides solid verification proofs. Any modifications to state variables must undergo strict validation before commits.

Requirements

• Update API configurations and SQLx pooling logic in backend/src/ for Verify Cross-Origin Resource Sharing (CORS) Bounds for Production.
• Expose clean endpoints under /api/v1/ state routing modules.
• Implement database indexes, pagination, or transaction safety decorators.
• Instrument endpoints using the global tracing framework for diagnostic visibility.

Acceptance Criteria

• Endpoints respond cleanly with standard HTTP status codes.
• Load tests demonstrate database connection pool limits remain stable under concurrent loads.
• Zero memory leaks or database socket errors occur during stress testing.
