Four papers, all on Zenodo under open licences, all citable. They are the reasoning behind RUBEN: why an in-car intelligence should sometimes say nothing, what identity means for a model trained on one person, and how a Transformer has to change before it is deployed where the consequences are human.
Silence as an Optimal Action: A Decision-Theoretic Foundation for the In-Cabin AI Companion
“We present a decision-theoretic foundation for in-cabin conversational AI in which silence is a first-class action.” Evaluated on 269 blind-labeled field turns, the proposed gate reaches a held-out F1 of 0.891 against 0.706 for the production binary gate.

Deployed Human Intelligence: A Protocol for Cognitive Identity on Synthetic Substrates
A protocol for cognitive identity on synthetic substrates, organised as “a twelve-layer epistemological stack”. Its closing line: “intelligence without identity is computation; identity without embodiment is abstraction; and abstraction, however fluent, does not see.”

System 0 Is Real. We Built It.
“This paper presents three novel algorithmic contributions to continuous cognitive AI architecture, grounded in peer-reviewed neuroscience.” The algorithms form the foundation of CerebellumNostrum, trained on MareNostrum 5.

From Attention to Attunement
“We propose the Attunement layer — an interface architecture that extends the Transformer with four operations: identity resolution, biological gating, evidential calibration and accountability”, positioned “as the necessary complement to Attention for deploying AI in human-consequential contexts.”
