curl --request DELETE \
--url https://api.mentionlab.io/api/entities/{id}/aliases/{aliasId} \
--header 'x-project-id: <x-project-id>'Removes a manual or LLM alias. If the alias has source “merge”, this triggers a full unmerge of the origin entity instead — the origin entity becomes independent again and all its aliases are restored. Returns 400 if a merge alias has no origin entity tracked (legacy data).
