Base JSON-RPC methods

This generated index contains exactly the 61 methods in the accepted Base catalog/OpenRPC contract. It describes Base mainnet (chain ID 8453) only; it does not publish the staged route or claim runtime readiness.

Evidence labels are independent axes: availability is one of unknown, key_required, or unavailable; validation is one of documented, parser_only, or positive_fixture. A positive fixture is a bounded observation, not blanket provider support.
