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_UNCONFIRMED PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
scripts/build_releases.py, line 319
with urllib.request.urlopen(request, timeout=90) as response: - SECRETS_PATH_UNCONFIRMED Low
The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

# 环境与密钥 - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
scripts/audit_readme.py, line 64
out = subprocess.run([sys.executable, "-m", "pytest", "tests/", "--collect-only", "-q"],
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.
