Thank you for the reconstruction—it's a great starting point. To verify its fidelity to the originals, please provide the exact PDF references from the NSA Venona declassification package you mentioned (e.g., file name, page numbers, and section titles where the worksheet appears). Then, using the actual example from those pages (not a generic reconstruction), walk through a complete end-to-end decryption of one of the VENONA messages shown there. Include:
The specific 5-digit code groups from the ciphertext (as printed in the PDF).
The corresponding reused pad additives (the 'depth' fragments that allowed cryptanalysis).
Digit-by-digit subtraction (mod 10) using the addition table you provided, showing the intermediate recovered codebook numbers.
Mapping those numbers back to plaintext words via the codebook indicators referenced in the document (e.g., how '157' might decode to 'LIBERAL' or similar from the 1944 State Department traffic).
The final partial English plaintext revealed.
If the PDF example uses a scanned worksheet image, describe it step-by-step as if transcribing the handwritten calculations. Sources: Stick to the NSA's 'VENONA: An Overview' monograph and the 1995-1996 declassification releases."
