Root Digit research library

Engineering papers with their assumptions visible.

Public, versioned studies built around quantitative models, reference architectures and explicit technical limits.

These papers inform engineering decisions. They are not certifications, regulatory approvals or substitutes for system-specific validation.

Publication standard

How to read our research.

01

Assumptions

Models identify the boundary conditions, inputs and illustrative assumptions that shape the result.

02

Evidence

Calculations, references and architecture decisions remain visible so a technical reader can challenge them.

03

Limits

Where evidence is modelled, illustrative or dependent on system-specific validation, the document says so.
