  "methodology": "Systematic approach: identified cipher type from description and ciphertext properties, then applied appropriate decryption. Caesar by brute-force shift testing, substitution by frequency analysis, Vigenere by known key from keyword pool, transposition by block reversal. Combined cipher proved intractable within time limit."
