Mar 1, 2025March 2025 focused on hardening concurrency and improving reliability of rate-limiting in the cadence repository, with a concrete fix that reduces production risk and stabilizes workflow throughput. Implemented a race-condition fix in the ratelimiter wrapper for synchronous Wait rejection, ensuring tokens are canceled without releasing the lock and aligning behavior with benchmarking results. This change directly improves correctness under high contention and prevents over-limit waiting, contributing to more predictable performance in production workflows.
