The following graphviz dot graph describes paths through the callgraph that could lead to a function calling a goroutine:
digraph G {
"(handleDegradedInstance, 3)" -> {"(waitForInstanceStop, 3)";}
"(waitForInstanceStop, 3)" -> {}
}

Open ec2_degraded_instances_restarter.go at lines 248-250 and inspect the range loop together with handleDegradedInstance. Trace whether the referenced instanceId can be used after the goroutine starts, then classify the analyzer finding as Bug, Mitigated, or Desirable Behavior using the linked classification guidance.
