browser-takeover/extension/background.js, line 79
const response = await fetch(`${BRIDGE_URL}${path}`, { - SECRETS_PATH_UNCONFIRMED Low

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.
