Summary

• Adds a dependency-free reproducible artifact capsule module for scientific data/code hosting.
• Builds folder-aware artifact manifests with SHA-256 hashes, file classification, metadata previews, FAIR scoring, environment readiness, and compute trigger plans.
• Exports JSON-LD, DataCite-style metadata, and schema.org dataset distribution payloads.
• Includes a demo script, reviewer demo transcript, requirement mapping README, and unittest coverage.

Validation

• py -m unittest discover scientific-data-code-hosting -v (7 tests passed)
• py scientific-data-code-hosting\demo.py
• py -m py_compile scientific-data-code-hosting\artifact_capsule.py scientific-data-code-hosting\demo.py scientific-data-code-hosting\test_artifact_capsule.py
• git diff --check

Reviewer demo

• See scientific-data-code-hosting/DEMO.md for the command transcript and proof checklist.

Notes

• No credentials, cloud accounts, private data, or external services are required.
• The implementation is intentionally self-contained so reviewers can run it in a bare Python environment.
