| 9 | +## Core Hierarchies: Fully Compliant |
| 10 | + |
| 11 | +All major public API hierarchies now have clean **Interface -> Abstract Base -> Concrete** chains: |
| 12 | + |
| 13 | +| Hierarchy | Chain | Status | |
| 14 | +|-----------|-------|--------| |
| 15 | +| Filter | `IFilter` -> `AbstractFilter` -> concrete filters | Complete | |
| 16 | +| Pipeline | `IPipelineNode` -> `AbstractPipelineNode` -> concrete nodes | Complete | |
| 17 | +| Plugin | `IPlugin` -> `AbstractPlugin` -> concrete plugins | Complete | |
| 18 | +| Parameter | `IParameter` -> `AbstractParameter` -> concrete params | Complete | |
| 19 | +| DataStructure | `IDataStructure` -> `DataStructure` | Complete | |
| 20 | +| DataObject | `IDataObject` -> `AbstractDataObject` -> all data objects | Complete | |
| 21 | +| Geometry | `IGeometry`/`IGridGeometry`/`INodeGeometry*` -> `Abstract*` -> concrete geoms | Complete | |
| 22 | +| DataStore | `IDataStore` -> `AbstractDataStore<T>` -> `DataStore<T>` | Complete | |
| 23 | +| ListStore | `IListStore` -> `AbstractListStore<T>` -> `ListStore<T>` | Complete | |
| 24 | +| SegmentFeatures | `ISegmentFeatures` -> `AbstractSegmentFeatures` -> concrete | Complete | |
| 25 | +| ArrayThreshold | `IArrayThreshold` -> `AbstractArrayThreshold` -> concrete | Complete | |
| 26 | +| JsonPipelineParser | `IJsonPipelineParser` -> `AbstractJsonPipelineParser` -> concrete | Complete | |
| 27 | + |
| 28 | +**14 complete chains, 100% `override` compliance, proper protected copy/move on all interfaces.** |

| 101 | +The following were verified as value/utility classes with no virtual methods: |
| 102 | + |
| 103 | +`DataMap`, `DataPath`, `LinkedPath`, `Metadata`, `Application`, `Preferences`, `Arguments`, `FilterHandle`, `FilterList`, `Parameters` |

| 120 | +--- |
| 121 | + |
| 122 | +## Recommended Next Steps (Phase 15) |
| 123 | + |
| 124 | +### Priority 1: Fix I-prefix naming violations |
| 125 | +Rename the 8 misnamed `I`-prefixed classes to `Abstract*`: |
| 126 | +- `IDataCreationAction` -> `AbstractDataCreationAction` |
| 127 | +- `IDataIO` -> `AbstractDataIO` |
| 128 | +- `IGeometryIO` -> `AbstractGeometryIO` |
| 129 | +- `IGridGeometryIO` -> `AbstractGridGeometryIO` |
| 130 | +- `INodeGeom0dIO` -> `AbstractNodeGeom0dIO` |
| 131 | +- `INodeGeom1dIO` -> `AbstractNodeGeom1dIO` |
| 132 | +- `INodeGeom2dIO` -> `AbstractNodeGeom2dIO` |
| 133 | +- `INodeGeom3dIO` -> `AbstractNodeGeom3dIO` |
| 134 | + |
| 135 | +### Priority 2: Easy interface extraction |
| 136 | +- Rename `AbstractStringStore` to `IStringStore` (already has no data members — it IS a pure interface) |
| 137 | + |
| 138 | +### Priority 3: Optional interface extraction (medium priority) |
| 139 | +- Extract interfaces for messaging/observer classes if full COM consistency is desired |
