  "conclusion": "The calibrated heuristic did not recover readable English from the Vumarii target under an unrestricted simple monoalphabetic substitution. This narrows only that candidate family; it is not proof that the image contains no message or no English-related operation.",
  "limitations": [
    "The author does not select English, a simple substitution, or this scoring model.",
    "The finite annealing search is a calibrated heuristic, not an exhaustive proof over every permutation.",
    "Other languages, keyed/polygraphic/multistage ciphers, and non-letter representations are outside scope."
