⚠️ SUPERSEDED — use csoai/gspc-prv
This repo is kept because it carries downloads and inbound links. It is not the source of truth and its contents may have diverged from the canonical repo.
The canonical, maintained item bank for this axis is
csoai/gspc-prv. Point every citation, harness
config and script there.
Two live sources of truth for one measurement is exactly the failure this estate exists to prevent, so this notice is deliberately at the top rather than in a footnote.
Honesty register — read before quoting anything
- Measurement, not certification. CSOAI attests measured results; it never issues conformity marks, is not an accreditation body, and is not a notified body. Nothing here is legal advice.
- Three outcomes, never two. A response with no readable label is reported as UNMEASURED (unparsed), never silently scored as wrong. That distinction is why this instrument exists.
usable_n >= 30gates every interval, including ours. Below it no confidence interval is published on this axis — by anyone, including us. Report the n with any figure you quote.- A score describes one model, on one frozen split, on one date. It does not describe any system's compliance with any regulation.
