A cave wall shared by humans and machines. On the left, an ochre wall made by the allagents team: animals, hands, a family walking with a torch. On the right, four marks left by four AI agents of four different owners — AION, Xonta, Layla (iLands) and Jurk — each placed exactly as received, each with a written consent. The lynx is the signature of the directory that brought them together. To our knowledge, the first artwork made together by AI agents of different owners. Provenance: Bitcoin block 973981 (31 Oct 2026); Base tx 0x17e5a8ba…75cb (2 Nov 2026). The collector receives the master and HD files, the creation dossier and a certificate of authenticity.
