The Unified Reality-Observer-Agent State and Transition Model: Joint State, Non-Collapse, Coupled Transitions and Transformation Across Participation Episodes

Abstract

This preprint presents the Unified Reality–Observer–Agent State and Transition Model (UROAST), a conceptual and formal framework for representing consequential participation through a typed joint configuration of Reality, Observer, Agent, relational, epistemic, historical, goal, and policy/authority state. The model preserves Reality, Observer, and Agent as non-identical components while representing their evolution as potentially coupled. It distinguishes actual, accessible, estimated, represented, predicted, counterfactual, and desired states; defines purpose-specific projections with explicit lineage to the joint state; and models participation intervals through typed transition contracts with post-transition Consequence Access and Reality Return obligations. The paper’s contribution is positioned as integrative and formalizing, not as the invention of underlying primitives such as belief-state modeling, role separation, frame conditions, provenance, synchronization/freshness metrics, monitoring, or fault localization. A minimal discriminating executable/simulation evidence package compared a reality-only architecture, fragmented local-state architecture, and the B1/UROAST typed joint-state architecture under matched synthetic observation conditions. Across 6,000 synthetic consequential-participation episodes, the joint-state architecture improved fault-localization macro-F1 from 0.688 to 0.982 relative to the fragmented comparator. In a lineage benchmark, material stale-projection incidents fell from 9.77% to 0% with explicit lineage checks. False closure fell from 18.22% to 1.83%, and unsafe continuation from 7.00% to 0%, with increased verification overhead. A separate 8,000-state test found essentially no incremental held-out predictive value for the proposed Synchronization Debt construct beyond freshness alone; that proposition is therefore retained as unsupported at the tested scope. Epistemic-lag evidence remains inconclusive, and several propositions remain open. Readiness and evidence status: R2 PASS with bounded coverage; R3-A PASS-SCOPED; M2 PASS-BOUNDED; R4 PASS-SCOPED at executable/simulation evidence class with REP-2 internal reproducibility; R5 PASS-BOUNDED for this exact Zenodo release candidate. R6 external test remains open. The reported evidence is synthetic/model-generated. It does not establish external-domain superiority, operational safety, universal validity, human performance, or independent replication. The public release includes the manuscript and the reproducibility package for the reported R4 benchmark results.
