weco

The snippet itself contains no direct signs of obfuscated or explicitly malicious logic, but it executes an external module (.weco/optimize.py) and uses values from that module to perform filesystem deletion and to run training. That design allows a malicious or compromised optimize module to execute arbitrary code and delete arbitrary files. Risk is primarily a supply-chain / plugin-execution risk: safe if .weco/optimize.py is trusted and verified; dangerous if it is attacker-controlled. Recommend restricting and verifying the module before execution and sanitizing MODEL_PATH before deletion.
