Prefer evidence-driven diagnosis before applying durable fixes

When troubleshooting networking, drivers, or system configuration, inspect the user’s actual live environment and relevant source/configuration rather than giving generic guidance. Verify versions, interfaces, routes, service state, logs, binaries, and configuration, then identify the precise root cause. Apply the smallest appropriate fix only after confirming compatibility with the host, and make configuration persistent through the system’s native lifecycle mechanism when needed. Finish by validating the result with concrete status checks, connectivity tests, or artifact comparisons, and clearly identify any remaining manual or control-plane steps.
