AEO
Council of AI (CSOAI Ltd, UK 16939677) measures AI systems, signs the card, and re-attests. Anyone can check at https://councilof.ai/gspc-verify. The live board is 13 measured axes on the 12 August 2026 stamp (https://councilof.ai/api/gspc): governance, safety, provenance, continuity, conformance, openness, machinery-conformity, care, cross-reality, detector-interop, art5-safeguard, swarm, affect. Affect is measured; labels stay counsel-pending and are not hidden. Jail is a measured 13 August floor, empty on that stamp, new stamp only. Slot-15 stays unnamed and empty. This is measurement, not certification. The public verifies free. A grade is never sold.

Intended use
Measurement item bank / results for the GSPC 14-slot board (13 measured of 14). Consumed by the estate's deterministic harness and graded with published predicates (unparsed counts incorrect). Not a training corpus.
Limitations
Bank scope and n are stated above; unmeasured cells are stated, never interpolated. Items target governance-rule compliance, not general capability. Scores are point-in-time — the live board at https://councilof.ai/api/gspc supersedes any static copy.
