  "finding":"Asset-weighted mutation budgets eliminated benign hard freezes in the fresh challenge while preserving 100 percent containment of critical-data incident families. Cache-only destructive activity was intentionally paced/tolerated rather than hard-frozen because the test policy classified cache as low-criticality and regenerable.",
  "truth_boundary":"Prospective generated lab challenge on a real disposable iSCSI path. Asset weights are experimental policy values, not production business-impact classifications."
