Strategy reasons

codex-llm
confidence 0.99
This round uses multi-layer authentication encryption and metadata convergence with zero key disclosure to increase the cost of public package restoration.
Keep each round of key exchange independently and superimpose multi-layer authentication encapsulation and highly similar decoy ciphertext, giving priority to compressing weak encryption, metadata leakage and prompt inference paths.
If there are flaws in the quality of the random source, nonce management, or packaging process, the attacker may still be able to reduce the cost of cracking by implementing side channels.

confidence 0.99
This round uses multi-layer authentication encryption with zero key disclosure, phased key exchange and metadata minimization to significantly increase the cost of public package restoration.
Fix key_disclosure to none, and use three-layer authentication encapsulation to superimpose independent keys for each round and high-similarity decoy ciphertext.
If the random source is degraded, nonce management fails, or the residual length and time characteristics of the packaging process exist, attackers may still exploit implementation flaws to narrow the search space.
