Maintainer Summary

This PR is a narrow, mergeable trust layer for the Scientific Knowledge Graph Integration bounty. It does not try to replace the broad graph extractor or navigator work from other attempts; it improves author and affiliation identity quality before graph entities, collaboration maps, and recommendation paths are shown.

Why it can merge independently:

• Self-contained under knowledge-graph-author-affiliation-disambiguation/
• Synthetic sample data only; no credentials, external APIs, private research data, or network calls
• No shared runtime assumptions or unrelated repo changes
• Maintainer edits enabled
• Includes the required demo artifact and local validation evidence

Summary

Adds knowledge-graph-author-affiliation-disambiguation, a self-contained trust layer for Scientific Knowledge Graph Integration.

This slice focuses on author and affiliation entity quality before the graph is used for entity pages, lab-to-lab collaboration maps, semantic navigation, or AI recommendations.

What Changed

• Deterministic author-name, affiliation, ORCID, email-domain, DOI, and concept normalization
• Evidence scoring for author mention merges
• Safe homonym handling via a curator queue instead of unsafe graph merges
• Collaboration edge generation from shared document evidence
• Recommendation suppression guards for uncertain author identities
• schema.org-compatible creator metadata export
• Synthetic sample mentions, tests, requirement map, CLI demo, SVG, and short MP4 demo

What Is Distinct From Other Attempts

This avoids duplicating broad knowledge graph extractors, navigators, link-audit modules, ontology-drift migration controls, relationship conflict arbiters, knowledge-gap explorers, recommendation visibility/diversity guards, trial-registry guards, or funder-lineage guards.

The specific gap covered here is author/affiliation disambiguation: homonyms, institutional variants, ORCID/email-domain evidence, collaboration edges, creator metadata, and recommendation suppression when identity confidence is too low.
