Persona library
Each LFI (Licensed Financial Institution) populates optional fields at different rates. The profile picks which assumption you see.
Mandatory fields are never redacted (EXP-04). Use + Compare to see two profiles side-by-side (EXP-16).
The short hash next to v2.1 is the commit SHA of the UAE Open Finance OpenAPI spec this sandbox was built from. Pinning a single SHA per build (D-01) means every field badge, enum, and validation result is anchored to one exact upstream version.
Hover the pin for the upstream repo path and retrieval date. The same SHA appears in dist/SPEC.json, the About page, and every fixture-package manifest.
