Annotation Metrics Reporting and Analysis Modules for the Ensembl Assembly/Annotation Tracking App

The Ensembl Assembly/Annotation tracking application stores rich quality metrics for thousands of genome annotations but currently lacks tooling to surface or compare them in a way annotators can act on. This project builds two Python modules on top of the existing backend services. The first generates structured per-genome annotation reports including BUSCO scores, coding gene counts, annotation method, and visualisations. The second enables taxonomy-grouped comparative analysis using PCA and outlier detection across clades, so annotators can immediately see whether a genome looks unusual relative to phylogenetically similar species. Both modules extend the existing services layer (annotations_service.py, report_annotation_service.py, report_assembly_service.py, taxonomy_service.py) without replacing anything, follow the ensembl-genes coding standards (pylint, mypy, black, pytest), and are built to be extended as the data model grows.
