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.
Rescanned at commit 83ceddf9255a, unchanged since the check below.
NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
apps/dashboard/src/dashboard.jsx, line 51
const res = await fetch(`${OCULTAR_API}/system/status`); - SECRETS_PATH_DOTENV Low
Mentions a .env file.
apps/sombra/start.sh, line 23
if [ -f src/.env ]; then - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
apps/automation_bridge/main.go, line 139
cmd := exec.Command(cmdDef.Command, cmdDef.Args...) - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
apps/proxy/main.go, line 60
keyMaterial := os.Getenv("OCU_MASTER_KEY") - OBFUSCATION_FILE_OVER_READ_CAP Note
A file was over the read cap and was not fully 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.
What was checked
Plain notes from the hygiene checks.
