May 2026: Delivered stability and reliability improvements in grafana/alloy Loki processing pipeline. Implemented a fix for error wrapping in the match stage to ensure correct error unwraps and future compatibility, and introduced a Stopper-based graceful shutdown for the limit stage to prevent goroutine leaks during shutdown. Updated tests to cover new shutdown semantics and error-wrapping behavior; verified with go test -race and lint.
