libboost-json1.83-dev 1.83.0-2.1ubuntu2 (riscv64 binary) in ubuntu noble

 This library focuses on a common and popular use-case: parsing
 and serializing to and from a container called value which holds
 JSON types.
 .
 Any value which you build can be serialized and then deserialized,
 guaranteeing that the result will be equal to the original value.
 Whatever JSON output you produce with this library will be readable
 by most common JSON implementations in any language.
