Reproducible cryptanalysis: a statistical test arguing Beale Cipher #1 is a hoax (p<5e-6), the 1885 Beale #2 solve, and a from-scratch reproduction of the 2020 Zodiac Z340 break.

LockJaw is a secure messaging system built on a three-layer hybrid encryption pipeline. — Zero-Trust, End-to-End Encrypted, Single-Machine Deployable. The server acts as a **pure router** — it never sees plaintext, never stores Beale phrases, and never holds decryption keys. All cryptographic operations happen exclusively on the client nodes.
