PROFILE
Katherine Hough
Katherine Hough contributed to the cedar-policy/cedar-spec repository by developing and refining backend features that improved policy parsing, formatting, and schema conversion. She expanded fuzz testing and symbolic execution coverage using Rust, enhancing parser reliability and surfacing edge cases early in development. Katherine upgraded protobuf dependencies for better serialization stability and enforced code formatting standards through CI/CD integration with GitHub Actions. Her work addressed error handling in JSON Schema to Cedar transformations, reducing manual intervention during schema migrations. By focusing on code refactoring, dependency management, and robust test coverage, Katherine delivered maintainable solutions that increased reliability and streamlined policy evaluation workflows.

Nov 1, 2025Month: 2025-11. This period focused on strengthening robustness in cedar-spec by addressing conversion-time errors in JSON Schema to Cedar transformations. Key deliverable: a bug fix that allows the conversion process to proceed when encountering unconvertible entity type shapes, preventing failure on unsupported types and reducing manual intervention. This improvement reduces downtime in schema migrations, improves throughput for downstream consumers, and stabilizes CI pipelines that rely on schema conversions. The change is implemented in the cedar-spec repository with commit 754a3429298a26489737040aa440603617f0f8ec and aligns with quality standards (Signed-off-by: Katherine Hough).

Sep 1, 2025September 2025 monthly summary for cedar-spec: Delivered two primary features that strengthen code quality and test robustness, with notable impact on maintainability and risk reduction. CI/CD Rustfmt Enforcement in CI Workflows added a rustfmt component to the Rust toolchain in CI to enforce code formatting during builds and tests, improving consistency and early quality feedback. SymCC Fuzzing Targets Expansion introduced new binary targets and Rust sources for policy checking to broaden fuzzing coverage and surface edge cases earlier in the development cycle. No explicit bug fixes were documented for this period; focus remained on feature delivery and quality improvements. The work demonstrates solid proficiency in Rust, CI/CD pipelines, formatting standards, and fuzzing workflows, delivering measurable business value through higher code quality, faster feedback, and stronger policy robustness.

Jun 1, 2025June 2025 monthly summary for cedar-spec (cedar-policy/cedar-spec). Delivered a pivotal protobuf upgrade to v0.14 to improve stability and compatibility of protobuf serialization/deserialization across the codebase. Implemented prost and prost-build v0.14 upgrade across multiple Cargo.toml files, coordinated in a single change. This work reduces runtime protobuf-related issues, strengthens downstream interoperability, and lays the groundwork for easier future upgrades. Commit reference: bff6ca4adff00ea9577e71237822adc8f12eef37.
