The REAL E3 Stability Triad: Architecture Overview and Governance Design

This paper is the architecture overview of the REAL E3 Stability Triad: three field operators, Field Guard, the Presence Layer, and the Relational Field Stabilizer, that together govern a relational AI trajectory. It describes the design at a high level, the coupling structure, and the deployment approach. It is not a proof: every certified claim is proven in the companion papers, above all the compositional certificate WP-RE3-COMP-001P (10.5281/zenodo.20442426). This public edition states the architecture and the certified headline results. Coupling coefficients and governance thresholds are in the restricted edition (10.5281/zenodo.20442747). Subject to patent application PRH2, filed with the Finnish Patent and Registration Office, April 1 2026. New in version 1.2. A scope synchronisation with no new mathematics. Earlier editions stated, correctly at the time, that the trajectory-level joint guarantee was not yet formalized. It now is, so the scope wording and the stability-by-reference paragraph are updated to match the composition edition, and the qualifications that guarantee carries are summarised here. Published together with that edition rather than after it, so the family does not contradict itself for any period. RE3 are proprietary systems of REAL E3 Systems Oy, Finland. This document discloses the mathematical stability certificate for independent verification purposes only. The harness implementation code, state extraction methodology, and REAL-E3 internal architecture are proprietary and not disclosed. Publication does not constitute a licence to implement, reproduce, or deploy any component of the REAL-E3 architecture. This notice also applies to all prior publications by REAL E3 Systems Oy.
