Use when diagnosing a connectivity problem — timeouts, connection refused, DNS failures, TLS/cert errors, intermittent packet loss, or an unreachable service. Works the OSI layers bottom-up from evidence, isolates the failing layer, and reports a root cause with the proof behind it.

The guiding principle: you isolate failures by working the layers, not by guessing. "It can't connect" has a small, finite set of well-known causes, and each one leaves a distinct fing
