  The PDF `DOW-UAP-D54-Mission-Report-Mediterranean-Sea-NA.pdf` carries in its
  PDF metadata 'Title' field the value "DoW-UAP-D31", while its external filename
  (published on war.gov/ufo) uses the identifier "D54".

  This may indicate:
  (a) editorial renumbering between versions — the document was originally
      "D31" during preparation and renumbered to "D54" at release;
  (b) copy/paste error in the release template;
  (c) a separate "D31" document exists whose title was reused by mistake.

  O PDF `DOW-UAP-D54-Mission-Report-Mediterranean-Sea-NA.pdf` carrega no campo
  PDF metadata 'Title' o valor "DoW-UAP-D31", enquanto seu nome externo de
  arquivo (publicado em war.gov/ufo) usa o identificador "D54".

  Isso pode indicar:
  (a) renumeração editorial entre versões — o documento foi originalmente
      "D31" durante a preparação e renumerado para "D54" no release;
  (b) erro de copy/paste no template de release;
  (c) existe um documento "D31" separado cujo título foi reusado por engano.

severity: low
investigative_impact: |
  Does not affect substantive content (the page-7 UAP observation is independent
  of the report number). But raises doubt about whether a separate "DoW-UAP-D31"
  file exists in the corpus, and about the integrity of the release process.

  Não afeta o conteúdo substantivo (a observação UAP da página 7 é independente
  do número do relatório). Mas levanta dúvida sobre se existe um arquivo
  "DoW-UAP-D31" separado no corpus, e sobre a integridade do processo de release.

possible_explanations:
  - { explanation: "Editorial renumbering — D31 was internal name, D54 is public ID", confidence_band: medium }
  - { explanation: "Copy-paste error of title from another template document", confidence_band: medium }
  - { explanation: "A separate D31 exists and this D54 inherited its title by mistake", confidence_band: low }

recommended_actions:
  - "Check whether a separate DOW-UAP-D31 exists in the war.gov/ufo corpus"
  - "Cross-check internal titles of other DOW-UAP-D* documents to detect a pattern"
  - "Compare against AARO's official index if available"
