The diagram list (titles, types, questions, pins) lives in
_data/studies.yml.
All eight were finalized with archify finalize --quality showcase --repo-root <clone at the pinned commit>
(schema validation, verified delivery, strict provenance check, headless-browser check).
The JSON specifications (Archify candidates), the gate results and a regeneration recipe are in
assets/letta-code/archify/.
