Use evidence like `app/services/payments/client.rb references ENV[\"PAYMENT_API_KEY\"] inside a model callback`; never quote the actual key, token, password, cookie, private key, or credential value. If code-level confirmation is missing, downgrade or remove the finding. Never use representative file paths or fabricated line numbers as evidence.",
