  "title": "Could this be a specialized reference book?",

  "observations": [
    {
      "text": "Scan measurements of ink gaps agree with many transcribed word spaces, subject to alignment qualifications. Written forms vary with line position, and neighbouring word lengths show dependence within lines. Kalevala verse also reproduces the tested within-line rhythm. These results do not establish linguistic words or complete entries.",

      "text": "Published catalogue comparisons connect plant motifs across sections. Two stronger correspondences link the roots on f18v and f23r to neighbouring fragments 212 and 213 on f102r2. These are resemblance judgments, not identified species or a demonstrated copying direction.",

      "text": "The retained tests do not establish the proposed plant-label links. Visual recurrence has not supplied a stable written name that carries between the paired contexts.",

      ]
    }
  ],
  "inference": "These measurements constrain how the writing was constructed. Taken together, the patterns support coordinated construction more firmly than a particular purpose. A shared writing convention operating at word, line and local section scales could accompany a compilation assembled for consultation. Reference use remains an interpretation, not a finding.",
  "example": "A reader might recognize a root motif beneath a larger plant and again among selected plant parts. That makes reference use plausible. Reusing a drawing template or copying a common exemplar also fits. Calling the recurrence a picture citation adds an unproven function; it does not tell us what the nearby writing means.",
  "alternatives": [
    {
      "title": "Reference or mnemonic notation",
      "text": "Pictures and distinct inscription formats might help recognition and consultation. This requires stable textual referents or technical relations that have not been recovered."
    },
    {
      "title": "Meaningful language transformed by encoding",
      "text": "A code or production convention might obscure linguistic content. This could serve the same reference purpose, but no fixed key, language or successful unseen reading is established."
    },
    {
      "title": "A coherent visual compilation with structured pseudotext",
      "text": "Templates and disciplined writing can coexist without recoverable textual reference. This also needs a producer that meets the surviving constraints; failures of particular ciphers do not establish it."
    }
  ],
  "change": "A fixed textual mapping that predicts an independently established referent or technical relation on a genuinely unexposed sheet would connect the writing to content. Compositional linguistic recovery would favour encoding; stable nonlinguistic reference would favour notation. A failed prediction would reject that mapping, not every meaningful explanation.",
  "limits": "We cannot identify a medical household, Italian workshop, secrecy motive or single production campaign. No semantic winner is justified. The missing prediction is a condition for reconsideration, not a new experiment or compute assignment.",
  "corrections": "P-87 changes the identical-core cross-line repetition conclusion, not the within-line length rhythm. The seven stronger grouped correspondences share physical folio 102; eligibility closed without scoring. Fontana s132 failed its frozen gate, and Egerton s133 remains process-invalid and unscored.",
