Save an approved finite expansion policy. Creation does not search or import.

Execute the saved policy: search, download arXiv sources, import unique strong candidates and record resolutions without per-paper prompts, within approved budgets. Resume with the same run ID.

List saved expansion summaries, optionally filtered by state.

Record exactly one candidate_id, target, existing_paper_id, skip:true or retry:true. Advance separately to execute the approved choice.

Pause scheduling after the active step. Advance explicitly to resume.

Permanently stop this run, preserving imported papers and history.

Return saved JSON or Markdown without writing client files or using network.
