split point {split} classified as {}, expected {kind}

Error message

split point {split} classified as {}, expected {kind}

What it means

When an explicit split point was requested, the generated split is classified and compared against the requested kind; a mismatch (e.g. asking for index but the resolved split behaves as a fraction boundary) aborts generation with this message naming the split and both kinds.

Solutions

1. Choose a split point value that lands on a boundary of the requested kind
2. Regenerate with a random split if the exact boundary is not required
