+- `minimum`, `exclusiveMinimum`, `maximum`, `exclusiveMaximum`: only supported for `"type": "integer"` for now, not `number`
+- `$ref` handling is a bit buggy (https://github.com/ggerganov/llama.cpp/issues/8073)
+- [pattern](https://json-schema.org/draft/2020-12/json-schema-validation#name-pattern)s must start with `^` and end with `$`
 - Remote `$ref`s in the C++ version (Python & JavaScript versions fetch https refs)

 - `string` formats `uri`, `email`
