## What - Keep files when the field's null count is missing during `NOT STARTS WITH` pruning. ## Why - A missing count is unknown. It does not prove that the file has no nulls. ## Implementation - Treat absent counts as unknown. Only rule out null rows when the count is known to be zero. ## References - [Iceberg spec: manifest metrics](https://iceberg.apache.org/spec/#appendix-c) - [Java InclusiveMetricsEvaluator](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/expressions/InclusiveMetricsEvaluator.java) - [Java InclusiveEvalVisitor](https://github.com/apache/iceberg/blob/main/api/src/main/java/org/apache/iceberg/expressions/InclusiveEvalVisitor.java) -- This is an automated message from the Apache Git Service.
