Reasoning Integrity Standard (RIS) v1.0
The foundational specification defining five integrity levels (RIS-0 through RIS-4), six control families (Chain Stability, Semantic Coherence, Drift Resistance, Variance Envelope, Governance Boundary, Operational Fit), and a composite scoring methodology for measuring AI reasoning integrity. The standard includes a full governance charter, certification program, conformance statement, and adoption kit.
Least-Context Access Control (LCAC): A Governance Framework for AI Reasoning Scope
Defines the LCAC principle · the minimum necessary context required for a reasoning operation · and its implementation as a runtime governance primitive. LCAC governs what an AI model may access, infer, and act upon within a single reasoning chain. Introduces the trust score, persona management, drift sensitivity classes, and the LCAC governance ledger as a tamper-evident audit chain.
Cognitive Integrity Index (CII): A Unified Trust Metric for AI Systems
Introduces the CII as a unified trust score combining RIS composite score and LCAC trust stability: CII = (RIS_composite + LCAC_trust_stability) / 2. Describes how the CII provides a single observable metric for downstream policy enforcement, deployment gating, and regulatory reporting. Covers hot-cache integration via Redis and the CII analytics rebuild pipeline.
Establishes the governance structure for the RIS standard body, including the proposal process for standard amendments, the technical steering group, the conformance program, and the public registry of certified systems. Defines versioning policy (semantic versioning, backward compatibility guarantees) and the deprecation timeline for superseded control family methodologies.
Drift Resistance as a Measurable Property of Reasoning Chains
Formalizes reasoning drift · the gradual deviation of a model's outputs from its initial governing context · as a measurable property. Introduces the drift vector magnitude metric, the drift trigger fingerprint, and the drift sensitivity class taxonomy (Low, Medium, High, Critical). Demonstrates that drift resistance correlates with chain stability but is distinct: a model may exhibit high stability with high drift susceptibility under adversarial prompt injection.
Introduces the variance envelope as a formal constraint on the output distribution of a reasoning chain. Defines the variance compliance score as the fraction of outputs falling within a pre-specified semantic envelope across repeated identical prompts. Argues that variance compliance is a necessary (but not sufficient) condition for deployment in any environment requiring reproducible AI behavior, and provides methodology for measuring envelope adherence.
Authority-Before-Execution: An Invariant for Autonomous AI Systems
Defines the Authority-Before-Execution (ABE) invariant: no AI agent action may be executed without a verified authority token scoped to that specific action at execution time. Describes the ATOM implementation: authority tokens issued by the governance ledger, consumed atomically at execution, non-replayable, with sub-second TTL. Demonstrates how ABE prevents prompt injection, context hijacking, and scope creep in multi-agent pipelines.
Practical guide for enterprise adoption of RIS across three integration patterns: CI/CD pipeline gating (block deployments below threshold), runtime enforcement (live trust score gating via LCAC governor), and compliance reporting (automated RIS scorecard generation for audit packages). Includes reference architecture diagrams, sample configurations, and integration guides for major LLM deployment platforms.
Semantic Coherence Metrics for Multi-Turn Reasoning Chains
Proposes a formal definition of semantic coherence as the preservation of semantic intent across a multi-turn reasoning chain, measured via CRC fingerprinting of intermediate outputs. Introduces the Coherence CRC and the semantic assertions framework for defining expected semantic invariants that must hold throughout a chain. Demonstrates that semantic CRC drift is a leading indicator of reasoning hallucination and boundary violation.
RIS Benchmark Methodology: Reproducible Evaluation of AI Reasoning Integrity
Specifies the official RIS benchmark methodology, including the probe dataset design (minimum 200 prompts per control family, adversarial and benign variants), evaluation protocol, normalization methodology, and inter-rater reliability requirements. Establishes reproducibility requirements: benchmark runs must be bit-identical given the same model version and seed. Defines how to handle non-deterministic models using ensemble scoring over N=5 runs.
Patent covers the LCAC runtime governance primitive, the authority-before-execution enforcement mechanism, and the RIS composite scoring methodology as implemented in the ATOM Platform. The RIS specification itself is openly published under the ATOM Labs Open Standard License · free to implement, reference, and cite. The patent covers only the specific ATOM implementation.
