Existing prompt-injection evaluations typically summarize security with terminal attack or policy outcomes, but equal endpoints can conceal different post-exposure traces and different losses of authorized utility. We introduce ContainmentBench, a sandboxed, trace-based benchmark that separately measures benchmark-defined endpoint policy compliance, instrumented logged propagation, recovery instrumentation, and authorized structured-action completion.
