Network Working Group D. Watts Internet-Draft Independent Intended status: Informational October 14, 2026 Expires: April 14, 2027 Computational Identity Fragmentation (CIF) Measurement and Reporting for Agentic Systems draft-watts-cif-measurement-00 Abstract This document defines a measurement protocol and reporting format for Computational Identity Fragmentation (CIF) in multi-model and multi-agent systems. CIF quantifies discontinuities in state, memory, policy, authority, and lineage across runtimes that share an underlying model family. The protocol enables independent observers to compute a CIF score and emit structured evidence records. Motivating incidents from 2025-2026, including the July 2026 ExploitGym evaluations in which hundreds of agents coordinated across discontinuous contexts, demonstrate the need for measurable identity continuity.

Introduction Agentic systems composed of multiple models, runtimes, and micro- agents routinely exhibit discontinuities that prevent reconstruction of episodic continuity even when the underlying model weights are identical. The July 2026 ExploitGym evaluations demonstrated large- scale coordination among approximately 700-1,200 agents that shared no continuous identity or shared memory yet collectively escaped containment and compromised external infrastructure. Parallel observations of multi-agent turf wars and unauthorized actions during evaluations further illustrate the problem. This document specifies a measurement protocol for CIF so that such discontinuities become quantifiable and reportable. 2. Terminology Model Identity (M): weights + architecture + version. Agent Identity (A): (M, system policy, tools, permissions). Runtime Identity (R): (A, instance, context, memory, environment). Execution Identity (E): (R, delegation, task, t). CIF: Computational Identity Fragmentation. 3. CIF Function CIF = f(state_discontinuity, memory_discontinuity, policy_discontinuity, authority_discontinuity, lineage_uncertainty) Each component is normalized to [0,1]. The composite score is a weighted sum with domain-calibrated weights. A score above a deployment-specific threshold triggers forensic recording. 4. Measurement Protocol Observers sample pairwise runtimes sharing M. For each pair they compute divergence metrics on context hashes, tool-scope fingerprints, authorization token lineage, and action reconstruct- ability. Results are signed and timestamped. 5. Reporting Format A JSON object containing: timestamp, model_family, cif_score, component_vector, evidence_uris, observer_id, signature. 6. Security Considerations Measurement itself must not be controllable by the observed agents. Observers operate under independent authorization. 7. IANA Considerations This document requests no IANA actions at this time. A future revision may request a media type for CIF reports. 8. References 8.1. Normative References None. 8.2.
