Add data code hosting ledger

[kkudumu]

@algora-pbc /claim #14

Summary

• adds a self-contained data-code-hosting-ledger module for scientific data/code artifact hosting
• supports artifact classification, folder-aware manifests, content hashes, versions, metadata-aware previews, dataset diffs, JSON-LD/DataCite/schema.org metadata, FAIR scoring, Docker runtime planning, and run/reproduce/scheduled triggers
• includes sample workspace data, dependency-free tests, requirement mapping, CLI demo, SVG source, and demo GIF

Demo

• Demo video: https://raw.githubusercontent.com/kkudumu/SCIBASE.AI/kkudumu/data-code-hosting-ledger-14/data-code-hosting-ledger/docs/demo.mp4
• data-code-hosting-ledger/docs/demo.gif

Verification

cd data-code-hosting-ledger
npm run check
npm test
npm run demo

Review Note

Before submission I ran a local code-review pass and corrected the README demo FAIR score to match the verified deterministic output.

Closes #14

/claim #14

Follow-up pushed to strengthen the sandboxed execution part of issue #14:

• added explicit sandbox policy output for runtime execution plans
• policy covers Docker isolation, network controls, resource limits, read-only artifact inputs, writable output paths, and blocked privileged actions
• surfaced the policy in the sample workspace, packet output, demo output, tests, README, and requirement map

Verification after the update:

• cd data-code-hosting-ledger && npm run check
• cd data-code-hosting-ledger && npm test
• cd data-code-hosting-ledger && npm run demo
• git diff --check

Follow-up pushed in 880db80 to strengthen the FAIR preservation/deposit side of issue #14.

What changed:

• Added buildPreservationPackage() for DataCite DOI registration readiness, repository export, schema.org indexing, required metadata gates, package-file hashes, and persistent access URLs.
• Hosting packets now include preservation output and the GET /workspaces/:id/preservation-package route contract.
• Demo output now shows ready deposit targets, package file count, and required gate status.
• Updated tests, README, and the issue Scientific/Engineering Data & Code Hosting #14 requirement map.

Verification rerun:

• npm run check
• npm test
• npm run demo
• git diff --check

Added a short demo video artifact for Algora/reviewer convenience:

• Demo video: https://raw.githubusercontent.com/kkudumu/SCIBASE.AI/kkudumu/data-code-hosting-ledger-14/data-code-hosting-ledger/docs/demo.mp4
• Existing GIF remains at data-code-hosting-ledger/docs/demo.gif
• CLI demo remains npm run demo

This is the same deterministic demo flow already covered by the local tests and README, now available as an MP4 video artifact.

Follow-up for the issue #14 drag-and-drop upload and folder organization scope.

Added commit 5ec5e04 to cover upload behavior that was previously lighter:

• drag-and-drop upload workflow plan with dataset/code/supplement drop zones
• accepted extensions for each drop zone
• folder routing and folder category rules
• resumable chunk upload routes and complete-upload route contracts
• expected content hashes, version requirements, and tag validation for datasets/models
• packet/demo output for uploadWorkflow
• tests, README, and requirement-map updates

Verified locally:

• npm run check -> passed
• npm test -> passed
• npm run demo -> passed and now prints upload workflow output
• git diff --check -> passed

This keeps the module self-contained while mapping more directly to the issue requirements for drag-and-drop uploads, folder-based organization, upload validation, and standards-compliant hosting workflows.

Updated the existing demo video with narrated voiceover explaining every major change in this PR: artifact classification, folder manifests, FAIR metadata, sandbox policies, preservation packages, drag-and-drop upload workflow plans, resumable chunk route contracts, hashes, versions, and tag validation. The PR's existing demo-video link now points to the narrated MP4.
