May 2025: Fixed intermittent RISC-V test timeouts in element-hq/synapse by implementing an architecture-aware timeout increase. The timeout is now applied only on detected RISC-V architectures, preserving existing behavior on other platforms. This change reduces flaky CI runs and improves overall test reliability, accelerating feedback for RISC-V users and developers. Commit reference: 07468a0f1c6ef07fe056e6a77347d045d34c69ff ("Increase timeout for test_lock_contention on RISC-V (#18430)").
