If the API returns aggregate as null on an error, agg.get(...) below might throw a NoneType error. maybe we can do agg = result.get("aggregate") or {} instead?

same here, if aggregate comes back null on a failure, result.get("aggregate", {}) returns None. we can use result.get("aggregate") or {} here too

perfkitbenchmarker/linux_benchmarks/kubernetes/agentic/k8s_python_density_benchmark.pyperfkitbenchmarker/linux_benchmarks/kubernetes/agentic/k8s_payload_benchmark.pyDescription: Adds two Python-focused GKE Agent Sandbox benchmarks:
Python Density: Measures Code Execution Latency (CEL), TTFE, RSS memory growth, and per-type latency breakdown (compute, syscall, import) at varying concurrent sandbox counts. Designed for density saturation sweeps.
Payload Transfer: Measures the cost of returning large observation payloads from gVisor sandboxes. Breaks down generation, serialization, stdout write, and total transfer time with throughput metrics.
