/claim #14

Summary

Adds scientific-artifact-provenance-chain, a dependency-free Node.js module for reviewer-verifiable scientific data and code hosting provenance.

This slice covers:

• content-hashed artifact records for datasets, code, figures, models, supplements, and environments
• metadata-aware previews for CSV/TSV and code artifacts
• dataset/code version diff summaries
• PROV-like activity chains linking inputs, commands, environments, and generated outputs
• FAIR validation with missing-license/runtime/reference warnings
• JSON-LD and DataCite-style exports for discovery and DOI workflows
• rerun plans that show which reviewer execution steps are ready

Demo

Run locally:

node scientific-artifact-provenance-chain/test.js
node scientific-artifact-provenance-chain/demo.js

The demo prints a validation result, rerun plan, JSON-LD export, and DataCite export for a soil-carbon notebook replay package.

Verification

node scientific-artifact-provenance-chain/test.js
# scientific-artifact-provenance-chain tests passed

node --check scientific-artifact-provenance-chain/index.js
node --check scientific-artifact-provenance-chain/test.js
node --check scientific-artifact-provenance-chain/demo.js

node scientific-artifact-provenance-chain/demo.js | head -120
# prints valid FAIR score, rerun plan, JSON-LD, and DataCite payloads
