Knowledge Graph Deep Dive: Evidence Expiration

Executive Summary & Graph Architecture

Autonomous mission intelligence is only as reliable as the continuous integrity of its underlying reasoning network. Unlike static governance models that verify authorization prior to execution, StratosIQ Assurance Intelligence establishes a continuous, dynamic knowledge graph to verify that evidence, assumptions, dependencies, and execution vectors remain verifiably trustworthy across the entire mission lifecycle.

By modeling Evidence Expiration as an active assurance knowledge graph node, StratosIQ enforces a Verification-First Validation (VFV) standard—continuously auditing evidence freshness, detecting reasoning drift, and recalculating operational trust before recommendations transition into physical actions.

Primary Intelligence Question

How does the Evidence Expiration node within the StratosIQ Assurance Intelligence knowledge graph enforce mission execution clearance by dynamically validating evidence freshness and dependency integrity?

Key Intelligence

The Evidence Expiration node integrates into the assurance graph by linking to Freshness/Expiration and Drift Detection nodes, which evaluate source provenance and operational drift. This traversal path feeds into the Verification State node, enforcing clearance states (`STALE`, `DEGRADED`, or `COMPROMISED`) before recalculating the Operational Trust Score—defined as (Evidence Quality Index) (Freshness Score) (Dependency Verification Ratio) – (Drift Penalty) – (Uncertainty Variance). Only when the Verification State is `VERIFIED` or `UNVERIFIED` (with sufficient confidence) does the system clear recommendations for physical execution, ensuring real-time trust alignment with mission intent. The Integrity Monitor recursively audits this process to detect deviations.

Assurance Graph Node & Ontology Primitives

To guarantee deterministic trust verification, StratosIQ structures continuous operational assurance through standardized ontology entities and relational properties:

• Evidence Integrity: Node representing source provenance, multi-source corroboration, and empirical verification weight.
• Verification State: Explicit node state (`VERIFIED`, `UNVERIFIED`, `STALE`, `DEGRADED`, `COMPROMISED`) governing execution clearance.
• Verification Coverage: Ratio mapping evaluated operational variables against total mission dependencies.
• Confidence Calibration: Dynamic statistical adjustment balancing evidence quality against environmental uncertainty.
• Operational Trust: Aggregated certainty index required to validate autonomous mission execution.
• Mission Assurance: Strategic state confirming that mission outcomes align with strategic intent and policy bounds.
• Traceability: Complete, immutable lineage mapping evidence nodes to recommendations and physical execution events.
• Integrity Monitor: Recursive agent continuously auditing system state for reasoning or environmental drift.

Continuous Trust Verification Metric

StratosIQ calculates real-time operational trust by measuring evidence coverage, source freshness, and dependency health against environmental drift and uncertainty penalties:

Operational Trust Score =

(Evidence Quality Index) (Freshness Score) (Dependency Verification Ratio) - (Drift Penalty) - (Uncertainty Variance)

Integrating evidence expiration into this graph architecture ensures that every autonomous recommendation and execution vector remains provably valid, continuously auditable, and resilient to operational drift.

Frequently Asked Questions

Q1: What is the purpose of the Verification-First Validation (VFV) standard in the StratosIQ architecture?

A1: The VFV standard is used to continuously audit evidence freshness, detect reasoning drift, and recalculate operational trust before recommendations transition into physical actions.

Q2: Which specific node states are used to define the Verification State within the assurance graph?

A2: The Verification State node uses the states `VERIFIED`, `UNVERIFIED`, `STALE`, `DEGRADED`, and `COMPROMISED` to govern execution clearance.

Q3: How is the Operational Trust Score calculated according to the continuous trust verification metric?

A3: It is calculated as: (Evidence Quality Index) (Freshness Score) (Dependency Verification Ratio) - (Drift Penalty) - (Uncertainty Variance).
