Renovate Merge Confidence
Merge Confidence is a Mend-operated data service that classifies each candidate update (Low / Neutral / High / Very High) using package age, adoption, test pass rates, and known vulnerabilities. Renovate consumes the Merge Confidence API to attach a confidence badge and reason to each PR and can drive `packageRules` to restrict automerge to High / Very High updates. The underlying API is publicly readable (no auth required for read) and lives under `developer.mend.io/api/mc/`.
