CSI proof block.

CSI proof block, 2025.

One published proof: the CSI value and data-state, the methodology version and confidence, the content-addressed hashes, the off-chain evidence pointers and the previous-proof chain link.

This proof block anchors one published CSI snapshot. Every value is derived from declared candidate inputs, carries an explicit data-state label and stays provisional until authenticated production lineage and the benchmark trusted gate pass. A missing or fail-closed proof renders as an explicit unavailable state, never a fabricated value.

Position in the append-only chain

This page shows the latest entry for 2025. Entries are append-only: a re-certification appends a new entry for a period rather than editing the earlier one, and the earlier entry stays in the chain labelled revised.

In plain English

CSI 2025 snapshot, revised (provisional).

Free-public composite CSI for WORLD 2025: the weighted composition of the eight first-class sub-indexes. This entry revises the previously anchored entry for the same period; the superseded entry stays in the chain. Real-sourced and provisional: certified on the candidate track (csi-v1.1.0), not yet benchmark-trusted.

The summary above is the block's own hashed text, written when the block was certified and preserved verbatim; the current publication state is the data-state label at the top of this record (derived from declared candidate inputs and provisional: certified on the candidate track, not yet benchmark-trusted).
