 ### Changed

+- refactor(schema): enhance schema command to support both single-table and multi-table formats
+- refactor(schema): improve output formatting with table-grouped results display
+- refactor(schema): enhance rule decomposition logic for multi-table support
+- refactor(data-validator): improve multi-table detection and processing capabilities
+- refactor(schema): preserve field order from initial JSON definition instead of alphabetical sorting
+- refactor(schema): consolidate field validation information display to single line per field
 
 ### Fixed
 - fix(cli): resolve issue where `--table` parameter was not correctly passed to backend
 - fix(cli): ensure table name from `--table` option takes precedence over table name in database URL
 - fix(tests): update regression tests to use new CLI interface format
 - fix(tests): resolve test failures caused by interface changes
+- fix(schema): resolve multi-table rules validation and type checking issues
+- fix(schema): improve table name detection and validation in multi-table scenarios
+- fix(schema): enhance error handling for multi-table validation workflows
+- fix(schema): ensure schema-only rule fields are not omitted from validation results
