Summary

/claim #14

Adds a focused FAIR artifact manifest validator for issue #14. This is distinct from broader storage-hosting submissions: it concentrates on the deterministic pre-upload/review contract for scientific artifacts before storage, DOI registration, publication, or execution.

Included:

• artifact type detection for datasets, code, notebooks, images, videos, models, and instrument output
• required FAIR metadata validation
• version change summaries for added/modified/removed artifacts
• JSON-LD, DataCite-style, and schema.org export payloads
• executable environment readiness checks
• FAIR scoring across findable, accessible, interoperable, and reusable dimensions
• upload gate decisions with blockers
• short demo GIF linked from the README

Transparency: AI-assisted with Codex and manually verified before submission.

Verification

• npm test (9/9 passing)
• node src/demo.js > /tmp/scibase-fair-demo.json && node -e 'const fs=require("fs"); const p=JSON.parse(fs.readFileSync("/tmp/scibase-fair-demo.json","utf8")); console.log(p.gate.status, p.fairScore.total, p.artifacts.length)' -> accepted 1 3
• for f in fair-artifact-manifest-validator/src/*.js fair-artifact-manifest-validator/test/*.js; do node --check "$f"; done
• file fair-artifact-manifest-validator/docs/demo.gif -> GIF 89a, 900x480
• git diff --check
