Strategy reasons

codex-llm
confidence 0.99
This round uses zero-key disclosure, multi-layer authenticated encryption and metadata convergence to compress the exploitable clues of the public package.
Select key rotation step by step, three-layer strong authentication encapsulation, and highly similar bait files to prioritize weak-cipher, metadata-leak, and public-key-hint attack surfaces.
If random source quality, nonce/key lifetime, or encapsulation consistency are implemented incorrectly, an attacker may still be able to narrow the search space by correlating features.

codex-llm
confidence 0.99
This round uses multi-layer authenticated encryption with key-changing and minimal metadata to compress the exploitable clues of the public package.
Choose zero key disclosure, three-layer independent encapsulation and high similarity bait set, focusing on covering weak-cipher, metadata-leak and public-key-hint.
If there are errors in random source quality, nonce/key lifecycle management, or encapsulation consistency, an attacker may still be able to narrow the search space by correlating features.
