benchmark/pm_benchmark/arena.py, line 446
market_prob = fetch(market) - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.github/PULL_REQUEST_TEMPLATE.md, line 23
- [ ] No secrets, tokens, or `.env` files included - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
benchmark/pm_benchmark/jev.py, line 81
key = api_key or os.environ.get("JEV_API_KEY") or os.environ.get("OPENCODE_API_KEY")
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.
