GSPC Pulse — the verifiable AI-governance evidence timeseries (CC0)

Append-only, timestamped snapshots of the GSPC live measurement loop: the 34-axis AI-governance board, the measurement-capsule index (OTS/Rekor anchored), the public card registry, HuggingFace open-source model signal (trending + 30-day new-with-traction cohort — never a downloads leaderboard), CISA Known Exploited Vulnerabilities, the global MCP handshake census, x402 catalog trust, and the DORA/XRPL signed-evidence corpus. One JSONL row per cycle; timeseries.csv is the flat-counter view; DIGEST.md is the one-glance state.

Doctrine

Measurement, not certification — states only, never grades or ranks. An auth challenge is a term sheet, not delivery. A 402 is NOT delivery. Relevant-to is never a determination. PENDING is never attested. Unreachable is never FAIL. Every number carries its source's own as_of.
