𝑸: How can I sort an inner array of an object? How can I sort all the arrays in a JSON entity? How can I modify a deeply nested array?

A: If the path to the inner entity is known, one can use |= as illustrated here:

{"array": [3,1,2] }
| .array |= sort
To sort all arrays in a JSON entity, no matter where they occur, one option is to use walk/1:

walk( if type == "array" then sort else . end )
