==== 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?
