Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
cg_vs_verilog_eval.py, line 147
comp = subprocess.run(["iverilog", "-g2012", "-o", str(d / "sim"), - INSTALL_UNPINNED Low
Dependencies use a range or git URL with no lockfile.
requirements.txt, line 6
mcp>=1.0 - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
cg_local_client.py, line 171

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
