notes: >-
  Fhenix's developer surface is a smart-contract + client-library stack, not a
  REST API. On-chain FHE is provided by the Solidity libraries (FHE.sol) in the
  FhenixProtocol/fhenix-contracts and cofhe-contracts repositories (consumed via
  git/Foundry/npm rather than a single canonical registry package). The client
  libraries above are the first-party off-chain SDKs.
