security-planning

Overall, this fragment is predominantly benign integration/test logic for TM7 generation/layout and validation. It does not show data theft, network exfiltration, hardcoded secrets, or obfuscation. The main security concern is execution risk: on Windows it runs a local PowerShell script with -ExecutionPolicy Bypass, and it also manipulates sys.path to prioritize repository scripts. These patterns should be reviewed/locked down in the supply chain (verify integrity of Deserialize-Tm7.ps1 and repository scripts) and, if untrusted XML paths are ever supplied beyond fixtures, consider XML parser hardening. Malware probability in this exact fragment appears low, but security risk from subprocess-driven execution is non-trivial.
