Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    integrations/zed/stub/src/main.rs, line 449 .env("PYTHONUNBUFFERED", "1");

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    integrations/zed/bootstrap/mcp_memento_bootstrap.py, line 243 result = subprocess.run(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    docs/dev/README.md, line 118 | Rust (via rustup) | Zed extension development | `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs \| sh` |

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    integrations/zed/stub/bin/memento-stub-aarch64-apple-darwin, line 1 ����

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.
