  "limitations": [
    "All counts are source-catalogue diagnostics, not proof that a genus never occurred elsewhere.",
    "The 26 shared cases were reviewed with source access disclosed. This is bounded research, not an exhaustive specimen inventory for every genus.",
    "Missing original accounts, uncertain historical material and genuine stratigraphic disagreements remain explicit. Retained uncertain genera are not approved hidden answers.",
    "The live game remains the 36-genus sample. Expert tree, standard-clue curation and eligibility remain unfinished; no new runtime hint, alias, age, diet or ancestry override is activated."
