I seem to remember that the specs are unclear if sorted hashes (aka objects) are allowed in JSON.

https://www.json.org/ is quite clear:

JSON is built on two structures:

[...]

An object is an unordered set of name/value pairs.

So, "objects" are not sorted, they have no implied order, but you are free to write them out sorted by any criteria you like. But you should not expect that the ordering is retained.

BTW: I think the name "object" is an unfortunate choice, because it is no object in the sense of object-oriented programming.
