Summary

• add a self-contained software/runtime version compatibility graph guard for Scientific Knowledge Graph Integration
• validate package/runtime semver ranges, immutable container digests, workflow engine ranges, lockfile provenance, and runtime capture freshness before recommendations are shown
• suppress unsafe graph paths, keep reviewable compatible paths visible, and emit curator actions plus entity-page packets
• include deterministic JSON, Markdown, SVG, and H.264 MP4 demo artifacts from synthetic data only

Safety

• no package registry, container registry, dataset, credential, external API, or network calls
• synthetic fixtures only in knowledge-graph-software-version-compatibility-guard/sample-data.js

Proof

• knowledge-graph-software-version-compatibility-guard/reports/demo.mp4
