March 2026 (facebook/sapling): Deliveries focused on safety, reliability, and alignment with external client changes. Implemented automated code-review skill integration, submodule path traversal hardening, empty-repo handling, merge-aware git export improvements, and test adaptations for git client upgrades. Result: safer, more deterministic reviews; stronger submodule security; robust handling of empty repos; preserved merge histories; and CI/test stability with updated client behavior.

February 2026: Config management modernization and observability improvements for facebook/sapling. Key changes include removing cryptographic signing from repository creation and SCM automation, replacing the signing verifier with an unsigned configerator, and introducing a JustKnob-controlled toggle to skip signing in create_repos. Also removed an unused CLI arg (crypto-path-regex) to streamline configuration. Added global log level configuration to improve observability, and performed Pyre-based typing refinements and minor code-quality fixes. These efforts reduced maintenance burden, enabled faster, safer repo creation, and enhanced debugging capabilities across the stack.

January 2025 (facebook/fbthrift): Focused on improving test robustness and Python configurability for Thrift server. Delivered bug fixes and a new Python-accessible configuration to align with the C++ interface, enabling better performance tuning.
