Show HN: Sigma Guard – deterministic contradiction checks for graph memory

Category: infrastructure

Tags: graph-database, consistency-checking, sheaf-cohomology

Score: 7.5/10 (Innovation: 8, Technical: 8, Documentation: 8, Utility: 6)

Sigma Guard is a pre-commit verification tool for graph databases that uses sheaf cohomology to detect structural contradictions within graph data, going beyond schema validation. It is innovative for applying advanced mathematical concepts to graph consistency, offers clear documentation with examples and integration guides for Neo4j and Memgraph, and fills a niche for ensuring logical coherence in complex graph-based systems like compliance or supply-chain graphs.

Target audience: backend devs, data engineers, devops
