Optional field / mental model when reviewing entries (trust tag or notes). From Round 3 catalog-ops research.
| Score | Meaning |
|---|---|
| 5 | Official / institutional source, stable URL, explicit license page, long track record (e.g. Kenney, Poly Haven, JAXA, Blender Studio) |
| 4 | Well-known maintainer + clear SPDX/CC text; minor caveats |
| 3 | Usable but license varies per item, or freemium caps need re-check |
| 2 | Aggregator / community dump — filter heavily; provenance uneven |
| 1 | Thin documentation; anonymous uploader; conflicting license claims |
| 0 | Blocklist / known trap — see high-risk.md |
Bump score down for: NC/ND clauses, engine-lock, AI free-tier ownership fog, abandoned upstream.
Re-verify licenses periodically; dead links → status: deprecated or fix URL.
