Start here. This is the direct spoken answer to practice first.
Overview
A release gate translates evaluation evidence into a decision before users absorb the experiment.
I define non-negotiable deterministic gates first, such as authorization, schema validity, and prohibited side effects. Quality gates then compare the candidate with the current baseline on representative cases and critical slices. Thresholds reflect failure severity, so a rare unsafe action can block release even when average usefulness improves.
