The artifact trail can no longer hide a produced document. The card listed only what the agent registered in state.md, so a file the workflow wrote but never declared was invisible. Every other document in the card's state directory is now listed too, under "Produced but not registered"; the workflow's own state, its backups, logs, and JSON bookkeeping stay out.
"Mentioned files" never guesses. It listed files the request never named — a split card's prompt names the parent card's path, and a basename search matched its own state file. It now shows only paths the request spells out that exist, and is labelled "Files named in your request", so the card states where the file came from.
