  // 1. deterministic: given a block height, returns the exact same response
  // upon multiple calls; and doesn't introduce any state-machine-breaking
  // changes across SDK patch version.
  // 2. consumes gas correctly.
  //
  // If you are a module developer and want to add this annotation to one of
  // your own queries, please make sure that the corresponding query:
  // 1. is deterministic and won't introduce state-machine-breaking changes
  // without a coordinated upgrade path,
  // 2. has its gas tracked, to avoid the attack vector where no gas is
  // accounted for on potentially high-computation queries.
  //
  // For queries that potentially consume a large amount of gas (for example
  // those with pagination, if the pagination field is incorrectly set), we
  // also recommend adding Protobuf comments to warn module developers
  // consuming these queries.
  //
  // When set to true, the query can safely be called
