Allure 3 report size inflates significantly compared to input files

[bubafinder]

The generated Allure 3 report size is disproportionately large compared to the source files.

Details

• Total size of input files (with traces): 374 MB
• Generated Allure report size: 2.9 GB

This represents a substantial increase in disk usage during report generation.

The same source files were used across multiple plugins, but not to the extent of an 8× increase. At most, the files appear to be reused approximately 2× on average.

Expected Behavior

The generated report size should be reasonably proportional to the size of the input files and should not increase by an order of magnitude without clear justification.

Actual Behavior

Allure 3 generates a report that is nearly 8× larger than the original data set.
