" summary

Clones the clouddriver repo, finds the exact commit via hal version --bom, and adds JVM debug flags so IntelliJ remote debug connects over the service port plus 100; forwards kubectl port-forward 47102 and 7002 to hit the pod and trigger breakpoints. Diagnoses a credentials endpoint that degrades from ~3–6s to ~90s at scale. For profiling builds a custom Docker image that copies the Glowroot jar and libs, adds the Java agent, swaps the image, and exposes Glowroot agent on port 4000 to collect traces and JVM metrics.
