Entity Integrity defines a retrieval-layer practice for keeping a person, organization, concept, or methodology represented as a distinct, current, and correctly attributed knowledge-graph node. It catalogs five failure modes: collision between separate entities, fragmentation of one entity into disconnected pieces, attribution drift, absorption into a generic category, and temporal collapse into an outdated snapshot. The proposed diagnostic uses the Encyclotron to create collision maps, fragmentation scores, attribution chains, and temporal-currency assessments. Repair is performed through disambiguation architecture: a JSON-LD entity definition, comparison matrix, negative tags, Semantic Integrity Markers, and consistent deployment across DOI, web, and publication surfaces. The Lee Sharks knowledge graph is presented as the worked example. Claims that a live AI system now resolves the entity correctly are empirical claims of the document and should be recorded as dated observations rather than assumed permanent outcomes.

## ABSTRACT
Entity Integrity is the practice of ensuring AI systems represent an entity as a distinct, correctly attributed node in knowledge graphs and retrieval systems. Entity Integrity failures manifest as confusion with similarly named entities, attribution of work to the wrong organization, fragmentation of a single entity across multiple disconnected descriptions, or collapse of distinct entities into a single generic entry. This document defines the practice, catalogs failure modes, and presents a worked example with verified results.

## THE IDENTITY PROBLEM
You have a name. So does someone else. The AI does not always know the difference.
Entity Integrity failures are among the most common and least diagnosed problems in the AI retrieval layer. They occur when the retrieval system cannot distinguish between entities with overlapping names, fields, or descriptors — and resolves the ambiguity by collapsing, confusing, or fragmenting the entities involved.
For individuals: a researcher's work is attributed to a differently named colleague at a different institution. A founder's biography is contaminated with another person's career history. A public figure's AI Overview draws from someone else's publications.
For organizations: a company's AI description incorporates a competitor's product features. An institution is confused with a similarly named body in a different field. A brand's differentiation is merged into a generic category description.
For concepts: a proprietary methodology is absorbed into a generic term. A coined framework is attributed to the wrong author. A distinctive philosophy is compressed into a standard category label.
These failures are not random. They follow predictable patterns that can be diagnosed, mapped, and corrected.

## FAILURE MODES
Failure Mode
Description
Example
Entity Collision
Two distinct entities merged into one
"Lee Sharks" conflated with "Lee Sharkey" (AI safety researcher)
Entity Fragmentation
One entity split into disconnected pieces
Basecamp (product), Shape Up (methodology), and DHH (founder) treated as separate entities
Attribution Drift
Work credited to wrong entity
A framework cited without its originator
Category Absorption
Distinctive entity compressed into generic category
A philosophy-first company described as "simple PM tool"
Temporal Collapse
AI locks entity into outdated snapshot
Founder described by 2015 role, not current work

## THE DIAGNOSTIC METHOD
Entity Integrity is assessed using the Encyclotron (DOI: 10.5281/zenodo.19474724), specifically at Level 1 (Entity Recognition) and Level 5 (Founder Entity). The key diagnostic question at each level: does the AI resolve this entity to the correct, current, distinct node?
The diagnostic produces:

## THE FIX: DISAMBIGUATION ARCHITECTURE
Entity Integrity is restored through a Metadata Packet for AI Indexing (EA-META-01) — a structured document containing:
---
## WORKED EXAMPLE: LEE SHARKS KNOWLEDGE GRAPH
The problem: "Lee Sharks" has collision risk with "Lee Sharkey" (AI safety researcher at Anthropic/Google DeepMind) and "Lei Yang" (marine biologist). Without intervention, AI systems may confuse publications, institutional affiliations, or research domains.
The intervention: A complete Metadata Packet (DOI: 10.5281/zenodo.19520783) was deployed containing all seven components: JSON-LD entity definition, three-way disambiguation matrix, keyword block, negative tags, SIMs, DOI reference list, and evidence membrane.
The result: Search "Lee Sharks" in Google AI Mode. The AI Overview correctly identifies: operative semiotics scholar, Crimson Hexagonal Archive operator, Semantic Economy Institute, Detroit. No confusion with Lee Sharkey or Lei Yang.
Verification: Live and verifiable now. Click any DOI. Read the AI Overview. The entity resolves correctly.

## WHO NEEDS ENTITY INTEGRITY

## RELATED DISCIPLINES
Entity Integrity is the disambiguation dimension of a unified methodology. Retrieval Architecture (EA-RA-01) provides the broader constructive framework. Retrieval Forensics (EA-RFO-01) investigates distortion patterns. Compression Diagnostics (EA-CD-01) quantifies the damage. Metadata Packets for AI Indexing (EA-META-01) specify the deployable artifact. Semantic Sovereignty is the goal state — the entity controls its own representation.
