1. info critical → info by review dynamic-execution scripts/unicode.py:39:9

   `os.system` called on a non-literal command — runtime-determined shell invocation (ast pass, confidence 0.85)

       if not os.path.exists(os.path.basename(f)):
           os.system("curl -O http://www.unicode.org/Public/UNIDATA/%s"
                     % f)

   likely benign LLM, confidence 0.80 A setup script shells out to curl via os.system to fetch Unicode data files from unicode.org when they are absent locally.

   Reasoning

   The snippet is a helper that downloads Unicode Character Database files from unicode.org with curl when they are missing locally. The URL is a well-known, legitimate source, and the surrounding check suggests a setup or data-fetch script. The AST flag is valid: os.system with a %-formatted non-literal string is a shell-injection risk if f is attacker-controlled. That is a code-quality problem, not evidence of malicious intent or obfuscation.
