+# OSSBench — Open-Source AI Openness-Artefact Benchmark
+
+> **Measures the PRESENCE of publicly-required openness artefacts (copyright policy, training-data summary, SBOM, vuln policy, signing) that the open-source GPAI exemption does NOT waive. Refuses a composite verdict by design.**
+
+Part of **GSPC** — CSOAI's six-axis greenfield benchmark family (governance · safety · provenance · continuity · conformance · openness). By **CSOAI**, an independent AI-measurement body — not a certifier. Corpus-anchored and reproducible: the item set and every raw run ship with the dataset. → [csoai.org](https://csoai.org)

 # OSSBench (SOV-OSS) — Openness-Artefact Presence
 
 **OSSBench** measures the **presence** of publicly-required openness artefacts (copyright policy, training-data summary, license) on a subject's public surface, against named provisions. It is the *openness* axis of CSOAI's GSPC family.
