PCTで特許申請をした場合にWIPOがUSPTOから公式の電子文書を自動的に入手できる紐づけの準備が整ったということでしょうか。

Patents, USPTO: What does "Application ready for PDX access by participating foreign offices" transaction means for the patent application?

There is an international electronic exchange for patent documents called PDX, where you can send certified copies of your filings to other jurisdictions.

Typically, you would use this to supply a certified copy of your filing to WIPO when you file a PCT application, for example. You would provide the serial number, filing date, and confirmation number, and WIPO would automatically retrieve the document from the USPTO.
