Relivio is a post-deploy decision engine: it watches the first 15 minutes after each deploy and sends exactly two notifications (deploy detected → final verdict). Instead of alert spam, it summarizes impact with a 0–100 score, STABLE/WATCH/RISK verdict, top signals (new errors, regressions, concentration, trend), and a Confidence indicator (baseline/coverage). Works with Slack, Discord, and generic webhooks.
