description: >
  Declarative manifest for the static/dynamic split. SKILL.md uses this to
  decide which fragments to load for a given paper-reading request. The main
  axis is the source format, which changes how text, figures, and tables are
  extracted before the bilingual reader is built.

always_load:
  # Shared layer — common to the nature-* skills
  - ../nature-shared/core/terminology-ledger.md
  # Skill-local core
  - static/core/principles.md
  - static/core/workflow.md
  - static/core/output-contract.md

axes:
  source_format:
    detect: |
      Determine the input form the user provided. Use pdf-text for a
      selectable-text PDF, scanned-pdf for an image-only or OCR-required PDF,
      html for a publisher or preprint HTML page, doi-arxiv for a bare DOI or
      arXiv identifier/link that must be resolved first, and pasted-text when
      the user pastes prose or notes with no retrievable original layout.
      If several apply (for example a DOI that resolves to a PDF), load the
      resolution fragment first, then the fragment for the resolved artifact.
    values:
      pdf-text:     static/fragments/source/pdf-text.md
      scanned-pdf:  static/fragments/source/scanned-pdf.md
      html:         static/fragments/source/html.md
      doi-arxiv:    static/fragments/source/doi-arxiv.md
      pasted-text:  static/fragments/source/pasted-text.md
    default: pdf-text
    multi: true
