I think this could be either a bug, or an issue with my understanding.
image below, why would the exact same feature class, put through the exact same geometry validator yield different results between readers

Hi @dfresh, I think it has been caused by a difference between implementations of extrenal libraries - Esri ArcObjects (GEODATABASE_FILE) and File Geodatabase Open API (FILEGDB). Esri ArcGIS has some tolerance internally, so I suspect that the GEODATABASE_FILE reader (Arc Objects) could repair invalid geometries implicitly in some cases.
I'm interested in what happens if you insert the ArcSDEGridSnapper after the FILEGDB reader.

+8What happens if you attach a GeometryFilter to each Reader?
Are they single part or multi-part features? Would de-aggregating help?
Note also that the ordering of the issues in the GeometryValidator can change the output geometries.
