Substitution: frequency analysis + known-plaintext attack starting with double-letter pattern (mppy=deep), then expanded mapping through contextual word fitting. Vigenere: tried ocean-themed keywords, tide was the key. Transposition: identified reverse-block with block size 3. Combined: tried all 5 candidate keywords with vigenere decrypt, then all 26 caesar shifts on each result; deep+caesar(21) produced English.",
