/claim #14

Summary

• Adds a self-contained scientific-artifact-hosting-governance module for Scientific Data & Code Hosting.
• Builds deterministic artifact manifests with type detection, SHA-256 content hashes, versions, access status, preview descriptors, and metadata completeness checks.
• Adds version/diff summaries, executable environment readiness checks, FAIR readiness scoring, JSON-LD/schema.org export payloads, DataCite export payloads, and an audit hash.
• Includes synthetic sample data, a CLI demo, tests, requirement mapping, and privacy-safe visual demo artifacts.

Demo

• Visual demo artifact: scientific-artifact-hosting-governance/docs/demo.svg
• Video demo artifact: scientific-artifact-hosting-governance/docs/demo.webm
• CLI demo: node scientific-artifact-hosting-governance/demo.js
• The demo uses synthetic data only and requires no credentials, live files, package installs, or external services.

Validation

• node scientific-artifact-hosting-governance/test.js -> passed
• node scientific-artifact-hosting-governance/demo.js -> produced reviewer-ready JSON with manifest, version diffs, FAIR exports, runtime readiness, and audit hash
• git diff --check -> passed

Notes

• Dependency-free Node.js implementation using only built-in modules.
• No credentials, live research data, cloud storage calls, or external APIs required.
• Scope is the broad artifact-hosting governance baseline; adjacent preview, retention, model-card, license, redaction, SBOM, and upload-checkpoint slices do not replace this layer.

Current status - 2026-05-29

Verified after newer same-issue #14 activity: this PR remains open, non-draft, CLEAN/mergeable, and distinct from KoiosSG PR #410. PR #113 is the artifact-hosting governance baseline; PR #410 is a separate malware/archive quarantine slice.
