May 2026 performance summary for ferdymercury/root: Implemented a threadsafe death-test style for TracingTests in the CppInterOp Testing Framework and added an environment variable to control test style, significantly improving test reliability in concurrent execution contexts. This work reduces flaky tests and increases CI stability, enabling more deterministic validation of interop code paths.

Month: 2025-12 — Focused on delivering a major interop library upgrade for root-project/root, with associated documentation and build improvements to reduce integration friction and enable broader platform support. This period centered on upgrading CppInterOp to 1.9.0, enabling out-of-process JIT, adding Doxygen comments retrieval, and enhancing Emscripten build instructions, all aligned with LLVM 21.x compatibility and longer-term maintainability.
