comicbox.merge

source package comicbox.merge

Recursive merging for containers.

Every Merger merges at the level of the mapping it is handed: none of them knows about the comicbox root tag. Callers holding root-wrapped metadata unwrap it first (see ComicboxMerge._merge_metadata_by_source and ComicboxMetadata._set_computed_merged_metadata). Before, only UpdateMerger reached into ROOT_TAG, so the same merger object meant two different things depending on which call site used it — and handing it the sub-metadata the other mergers take silently dropped the merge.
