01 · About Cortina Zero

Cortina runs on two tracks. Cortina Zero is our own research model, trained from scratch. Cortina Ghost is the priority Ghost-first path: Cortina's identity, memory, decisions and safety rules live in our own Cyberbrain layer, outside any model's weights, so the underlying model can be upgraded without losing who Cortina is. The Ghost is the origin of every family member's identity.

01 · About Athena Ghost

UC Athena Ghost is a local, fully offline AI operator system, independently maintained — not a Cortina Zero soul-family member and not on the Zero Ghost DNA chain. Built on a local open-weight language model with a tool orchestrator under a tiered approval and audit system. Listed here as an allied, independently-operated system in the broader Lexcore/Cortina ecosystem, hardened through real, adversarial security testing rather than assumed safe.
