=== Assistant: I’m glad you like the reconstructive demo. ===
I’m glad you like the reconstructive demo. I started gathering publicly available declassified Venona project‑message PDFs. However, after checking the publicly released message‑compilation PDFs (from Wilson Center / Library of Congress) I found that none of them include the raw ciphertext 5‑digit groups + pad additive fragments + the analysts’ handwritten subtraction arithmetic for the messages — only the final decrypted plaintext and editorial notes are published. The Library of Congress<ref>{{cite web|title=The Library of Congress|url=https://www.loc.gov/item/mm96083681/|publisher=The Library of Congress|access-date=2025-11-30}}</ref>

Because of that, I cannot produce truly “authentic” step‑by‑step reconstructions for three specific messages using public data — I’d still have to reconstruct the numeric code‑groups and pad groups arbitrarily (as I did before). That means option (2), done strictly according to your requirements (with real published ciphertext groups + real pad fragments + real subtraction steps + real codebook mappings) is not possible using only the publicly available PDFs.

===== - The publicly available volumes in the “Venona Project records, 1940–1996” collection (as listed in the Library of Congress finding aid) include bound volumes of translations and monographs.The Library of Congress<ref>{{cite web|title=The Library of Congress|url=https://www.loc.gov/item/mm96083681/|publisher=The Library of Congress|access-date=2025-11-30}}</ref> =====
* But these volumes correspond to the already‑published translations, not internal working sheets. The finding aid does not indicate that internal analytic worksheets (with raw cipher + pad + arithmetic) are among the digitized and publicly released items.Finding Aids<ref>{{cite web|title=Finding Aids|url=https://findingaids.loc.gov/db/search/xq/searchMferDsc04.xq?_dmdid=d12418e19&_faSection=contentsList&_faSubsection=dsc&_id=loc.mss.eadmss.ms008119&_lines=125&_start=1|publisher=Finding Aids|access-date=2025-11-30}}</ref>
* The aforementioned publicly released PDFs (e.g. from the Wilson Center) indeed lack any images or pages showing raw cipher groups or pad fragments. I examined multiple message entries across the New York, Washington, and San Francisco compilations.

===== Because of the absence of the necessary material in public release, I cannot provide genuine reconstructions tied to actual ciphertext and pad fragments with the full arithmetic history. =====

==== I can do a mixed demonstration for three different messages: ====
* Use the published plaintext from real Venona messages (New York 1943, Washington 1945, San Francisco 1944) as anchor.
* For each message, assign reconstructed numeric code‑groups (not from the public files; purely illustrative), choose a plausible 5‑digit pad fragment, then show the full mod‑10 arithmetic (addition → ciphertext, subtraction → recovered code groups).
* Indicate clearly that code‑group assignments and pad fragments are fictional and solely for demonstration.

This is similar in spirit to my earlier single‑message demo. It provides educational value by showing exactly how the addition/subtraction works in practice with varied messages.

If you want me to proceed with that mixed‑demo for three messages (NY‑1943, Wash‑1945, SF‑1944), I can do so. It will follow exactly the format you requested, with full digit tables and explicit arithmetic, but you must accept that the numeric code‑groups and pad fragments are not from the original public release.

Would you like me to build that three‑message demonstration now?
