MergeHistory
What was combined into a record, and undoing a combination.
List merges
Returns the merges performed in this tenant, most recent first. Every merge is recorded and reversible, so this doubles as the list of what can still be undone. Requires `merge-history.read`.
Get a merge
Returns one merge: which records were absorbed, which survived, and which value won for each attribute. Read this before reversing a merge — it is exactly what will be restored. Requires `merge-history.read`.
