precondition, which we won't satisfy anywhere as we don't run tests on such hardware, will always be ignored.

Multiple occasions happened when engineers were caught by surprise finding tests not running anywhere (e.g., tests depending on non-LTS, cleaned up JDK distributions). This project is the result of an initiative to [redesign the [recondition] system](https://github.com/gradle/gradle/pull/22885), where we aim to precisely track if all preconditions are satisfied...

//
//   - converting from the [Value] types as provided by the sql package
//     into a database table's specific column type and making sure it
//     fits, such as making sure a particular int64 fits in a
//     table's uint16 column.
//
//   - converting a value as given from the database into one of the
//     driver [Value] types.
//

        This means we actually have to execute the code block in order to find the rule information within.
        This is also problematic because it means we have to serialize this information into some form that fits into annotations.

        Later, we will extract all the “up-front” information we need to know during compile time.
