Commits include test: certificate status storage encoding snapshots (#790), fix: storage compatibility issues (#815), and fix: CertificateStatusError encoding compatibility (#824). - Network Task Error Handling and Logging Improvements (agglayer/agglayer): Refined network task error handling to capture and log network IDs on failure; improved orchestrator robustness and cleanup of failed tasks. Commit: 19bdc43936d3bc4796ec2e006d4ca5544ff0a1f6 (fix: clean up network task after a failure (#812)). Overall impact and accomplishments: - Strengthened modularity and maintainability through crate consolidation, enabling easier future enhancements and faster build cycles. - Increased system reliability with regression-tested encoding fixes and clearer diagnostics, reducing maintenance costs and incident response time. - Improved runtime resilience of distributed tasks via robust error handling and cleanup, lowering risk of failed task cascades. - Demonstrated proficiency in Rust crate management, encoding/decoding data contracts, regression testing, and robust logging. Technologies/skills demonstrated: - Rust crates and build scripting practices (crate consolidation and dependency updates) - Encoding/decoding data representation and compatibility testing - Regression testing and improved diagnostics/logging - Robust error handling and task orchestration in distributed components
