Grade B
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.
NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
benchmarks/fetch_corpora.sh, line 39
[ -s "${AH}/${f}" ] || curl -fsSL "${AH_URL}/${f}" -o "${AH}/${f}" - SECRETS_PATH_DOTENV Low
Mentions a .env file.

for declaration in ("/workspace/**", "/workspace/.env"): - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
benchmarks/gateway_cost.py, line 100
(lambda t0: (subprocess.run([sys.executable, "-c", code], check=True, - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
benchmarks/bpl_sweep.py, line 268
os.environ.get("AZURE_OPENAI_KEY") or os.environ.get("AZURE_OPENAI_API_KEY")) - OBFUSCATION_FILE_OVER_READ_CAP Note
A file was over the read cap and was not fully read.

{ - OBFUSCATION_FILE_CAP_REACHED Note
The 400 file cap was reached before every file was read.

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.
