Silent Data Loss After Partition Switch When Squash Changes Partition Count

Silent Data Loss After Partition Switch When Squash Changes Partition Count: a task in LegoFlow-SWE (Harbor dataset). Expected behaviour: The switch operation should detect that the partition count changed due to squashing and abort the stale parquet linkage, preserving all O3 rows. The system…

The task

**Expected behaviour:** The switch operation should detect that the partition count changed due to squashing and abort the stale parquet linkage, preserving all O3 rows. The system should provide a configuration option that controls how many mid‑partition splits are allowed during such a switch; the default value of…
