# Why I could not produce the exact original worksheet arithmetic from the public PDFs - The public monographs and translation packets document the method and show the final decrypted plaintexts. They do not, in the public files I reviewed, include the actual internal handwritten worksheets that show the analysts’ original pad fragment extracts and the handwritten digit-by-digit subtraction steps. Those working worksheets appear not to be part of the standard public release bundles. If you require those exact original internal worksheets, they may exist only in internal archival FOIA files; we would need to identify the specific FOIA document ID or NSA archival file that contains them. nsa.gov<ref>{{cite web|title=nsa.gov|url=https://www.nsa.gov/Portals/70/documents/news-features/declassified-documents/crypto-almanac-50th/VENONA_An_Overview.pdf|publisher=nsa.gov|access-date=2025-11-30}}</ref>
# If you want an exact original worksheet reconstruction - I can: (A) help locate a specific FOIA/archival file or case file that might contain the internal worksheet images (this requires digging the NSA FOIA inventory for internal case files), or (B) produce a fully annotated reproduction of a published Venona translation using a reconstructed pad fragment (as I demonstrated above) that shows every digit operation step-by-step for educational verification. I recommend option B for immediate, verifiable arithmetic demonstration; option A if you need the literal original analyst handwriting and pad fragments for formal verification.

If you want me to proceed immediately with (A) locating possible FOIA/internal worksheet images (I will search the NSA FOIA catalog and the specific 1995–1996 release packets for any attached scans) I will do that next and provide exact FOIA document identifiers and page numbers where worksheets appear — but note: the public release PDFs I checked do not contain the internal arithmetic worksheets, so a FOIA document search is the correct next step if you require the literal original internal worksheet image. If instead you want me to produce more reconstructed, fully step-by-step decryption examples using specific published message numbers (I can pick a published message number from the release and show a demonstration like the one above, clearly labeled reconstruction), indicate which you prefer and I will proceed with that.
