Rescanned at commit a96ed7487545, unchanged since the check below.

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/remember-summary-cap-probe.ts, line 412 fs.rmSync(tmpRoot, { recursive: true, force: true });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/recall-synthesis-budget-probe.ts, line 14 * 1. Loads provider credentials from `.env` using the project's

  • SECRETS_ENV_READ Note

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

    scripts/recall-synthesis-budget-probe.ts, line 1059 process.env.CURION_PROVIDER_PRIMARY_KEY ?? process.env.NVIDIA_NIM_API_KEY ?? "";

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    tmp/recall-synthesis-budget-probe.jsonl, line 1 {"config":"B","query_id":"orient-agent-runtime-status","query_family":"orientation","query_text":"What is the current agent runtime shape?","max_tokens":512,"model":"openai/gpt-oss

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.
