Error message

The following classes are not assigned to any collapsed category: {unmapped_classes}

What it means

Completeness validation at the end of build_collapsed_categories_config: after processing every category, some top-level classes remain unassigned (class_names minus seen_classes is non-empty). Because collapsing is enabled, every class must belong to exactly one category; otherwise get_category_for_class would hit its internal sentinel error at inference time. The message lists the leftover classes.

Solutions

1. Add each unmapped class to exactly one category under collapsed_categories.mapping
2. Create a catch-all category (e.g. 'other') for classes with no natural grouping
3. Alternatively disable collapsing with enable: false if per-class outputs are acceptable
