Strategy reasons

confidence 0.92
This strategy reduces the amount of information available in public packages through layered encryption, per-turn key exchange, and metadata minimization.
Use three layers of encryption and turn off key prompts, while adding decoy files and strict metadata convergence.
If the random source, padding or encapsulation process is inconsistent during implementation, attackers may still use file length and processing timing to perform correlation analysis.

codex-llm
confidence 0.88
I chose multiple layers of encryption with minimal metadata exposure to make the public package more resistant to recovery.
Use no key hints, per-turn key swaps, and multiple layers of encapsulation to compress the exploitable attack surface.
If the implementation details are wrong or the random number quality is insufficient, it may still be exploited by side channels or configuration errors.
