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 3763e64f521d, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    kernel/src/demo.ts, line 398 await fs.rm(knowledgeDir, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    kernel/docker-entrypoint.sh, line 29 const sock = net.connect(port, u.hostname);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    kernel/scripts/init-env.mjs, line 4 const target = new URL("../.env", import.meta.url);

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    kernel/integrations/claude-code/scripts/lib.mjs, line 8 const key = process.env.HALOMEM_API_KEY || "";

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    kernel/console/app.css, line 1 /* ---- Halofy design tokens (honoring NEW Halofy Design System/tokens) ---- */

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    kernel/console/app.css, line 1 /* ---- Halofy design tokens (honoring NEW Halofy Design System/tokens) ---- */

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.

  • Permissions

    Concern

    can delete files.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    a file was over the read cap and was not fully read. the file cap was reached before every file was read.
