Delivered the Rust Cargo SBOM Detector in microsoft/component-detection, enabling SBOM-based detection of Rust components. Implemented RustSbomDetector and JSON parsing contract classes for Cargo SBOM, with experiment configurations to compare against existing Rust detection methods. The initial implementation is tracked in commit f7af5db7848cad900857ba3e233cf30d05d9068f ("Initial implementation of cargo-sbom detector (#1387)"). No major bugs fixed this month. Overall, this work increases accuracy of Rust component inventory, supports SBOM-driven compliance and vulnerability management, and establishes a foundation for performance and reliability improvements. Demonstrated Rust, SBOM standards, JSON parsing, detector architecture, and experiment tooling skills.

Month 2024-12: Focused on stabilizing multi-source configuration in luong-komorebi/cargo. Delivered a critical reliability fix to the Configuration System by implementing non-mergable list handling: introduced is_nonmergable_list and updated the merge logic to replace rather than merge for these keys, preventing unexpected behavior when multiple sources define them. Added tests validating parent/child configurations for non-mergable lists (e.g., credential-provider). This work reduces cross-source config pollution and improves predictability in deployment configurations. Commits: 99c57c02d7392059ea1bc0b5b185e672845b7981 (fix(config): Don't merge unmergable config) and 1948c90a7882a8c11ba3e7f6f801bf3fa9ee0fa1 (Show existing behavior).
