Vector rules

• Validate geometry before storage or analysis.
• Repair simple invalid geometries only when documented and reported.
• Preserve source metadata.
• Use explicit CRS transformation.
• Export GeoJSON with stable properties.
• Keep analysis outputs traceable to input layer and analysis run.

Operations checklist

• Load vector data.
• Validate schema and geometry.
• Reproject if needed.
• Clip to area.
• Perform requested spatial operation.
• Store or export result.
• Add tests using small fixtures.

Completion report fields

• Operations implemented.
• Geometry types supported.
• CRS behavior.
• Tests run.
• Unsupported edge cases.
