 ## Asset provenance
 
+Toti was generated with Codex's built-in image generation tool on 2026-10-12 for THOTH
+and selected by the project owner for the README. The original generated PNG is preserved.
+The concept is a curious baby ibis with a curved beak, navy and gold scribe headdress,
+crescent accent, and a small notebook on a transparent background. It is a brand mascot,
+not a product screenshot. The existing illustration and vector assets remain available.
+
 The mark and lockup were drawn as SVG for THOTH. The ibis-headed Thoth illustration was generated
 with AI for this project and is used as brand artwork, not as a product screenshot or a reproduction
 of a historical object. These original three image files are preserved unchanged in this public copy.
