Provenance

RPC-pinned record: read over public JSON-RPC at the Ethereum block shown below and independently re-read at the same block by a second Pacta seat. It is not EAS-attested: no sprint number, no summary document and no Base EAS UID. Status RPC-observed baseline: the on-chain control plane is pinned at block height; whether it matches the protocol's documented parameters is not assessed here (the documentation is linked for reference). Machine-readable: /api/v1/rpc-pinned.json. The Base-EAS-attested Sprint records are in /api/v1/index.json.
