CDecide — “help me choose”A regulator requested a stamped copy of an experimental protocol with version and approval…+

A regulator requested a stamped copy of an experimental protocol with version and approval metadata by tomorrow morning. I have multiple drafts and scattered approval emails. I cannot invent approvals. Tell me the quickest defensible way to assemble a single stamped copy that accurately reflects what was approved, list the minimal metadata to include, and draft a short cover note that explains provenance without oversharing internal comments.

when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

How to do it

the tool · the steps · what to avoid

1
Open the PDF file you want to stamp in Adobe Acrobat (Pro version required).
2
Press Ctrl+J (Windows) or Cmd+J (Mac) to open the JavaScript console.
3
In the console, enter a JavaScript snippet to add a stamp, such as: this.addAnnot({type: 'Stamp', page: 0, name: 'Approved', rect: [100, 400, 200, 500]});
CautionEnsure the stamp name (e.g., 'Approved') matches an existing stamp in your Acrobat installation.
4
Modify the 'page', 'rect', and 'name' parameters in the script as needed to control the stamp’s location, size, and type.
Best practiceYou can loop through pages to apply the stamp to multiple pages automatically.
5
Press Enter to execute the script and apply the stamp(s) to the PDF.
6
Save the PDF to retain the automated stamp placements.

In the appWith the API

You can use the JavaScript console in Acrobat Pro to quickly test and run stamp placement scripts on your open PDF.
