A Theory of Least Autonomy in AI

Christophe Parisel

Least privilege, the principle that an identity should hold only the permissions strictly required for its task, has been a foundational primitive of access control for decades. We…

Evidence of Layered Positional and Directional Constraints in the Voynich Manuscript: Implications for Cipher-Like Structure

Christophe Parisel

The Voynich Manuscript (VMS) exhibits a script of uncertain origin whose grapheme sequences have resisted linguistic analysis. We present a systematic analysis of its grapheme sequ…

Privilege Risk Evolution for Non-Human Identities: A Temporal Fiber Model for Cloud IAM

Christophe Parisel

Cloud permission governance implicitly treats permission equivalence as a static relation. We show that for non-human identities (NHIs), equivalence has two irreducible components:…

A Quantitative Confirmation of the Currier Language Distinction

Christophe Parisel

We present a unified quantitative analysis of the Currier A/B language distinction in the Voynich Manuscript, proceeding in two stages. First, we confirm that the distinction is ge…

Out-of-Domain Stress Test for Temporal Braid Group Privilege Escalation Detection

Christophe Parisel

In a companion paper, we prove that the Burau-Lyapunov exponent LE discriminates focused from dispersed privilege escalation ratchets in cloud IAM graphs, and that no abelian stati…

Detecting Privilege Escalation with Temporal Braid Groups

Christophe Parisel

Within the Strongly Connected Components (SCCs) formed during the temporal evolution of a Cloud permission graph, we use the Burau Lyapunov exponent LE as an algebraic probe to loc…
