Taxon-Scoped UniProt Lookup + Version-Aware AlphaFold Retrieval

Life sciences / Structural biology — Taxon-scoped UniProt accession lookup plus version-aware AlphaFold DB structure retrieval. Keeps pLDDT/PAE quality triage strictly separate from oligomer and complex assembly flags, and requires recording exactly which AlphaFold structure version any derived quantity (such as a HullRad diffusion coefficient) was computed from. Encodes AlphaFold DB version-retention behaviour: latestVersion is authoritative for what can be downloaded today, while allVersions is a historical list only — older version-numbered structure, PAE, and confidence files typically 404 once an entry moves to a newer version. WHEN: "look up UniProt accessions for a…
