Broader Open DB context

Frame the target before identity details

Structured disease, protein, and project context should read before the lower-level identity rail.

As of 2026-09-13

Protein identity stays anchored to UniProt P47745. Use UniProt P47745 as the stable identity anchor, then attach disease evidence before program review.
