What's New in v4.03 — Phantom-Step Cascade Key Derivation

🔑 Phantom-Step Cascade — Deterministic Final Key Generation

SecretMemoryLocker v4.03 introduces an enhanced key derivation model based on a chained Argon2 cascade.

Core idea:

• Initial seed: k = file_hash_seed
• Each secret answer is processed sequentially
• Every step re-derives the key using the previous result as salt
• Final output becomes the deterministic final_key

Conceptually:

k = file_hash_seed

for answer in answers:
    k = Argon2(answer, salt=k)

final_key = k

🛡 What This Achieves

• Multi-layer entropy amplification
• Order-dependent cryptographic strengthening
• No stored master key
• Deterministic and reproducible recovery

This update strengthens resistance against brute-force and structural attacks while preserving full recoverability.
