| Name | Type | Description |
|---|---|---|
| feature_flag_variants | array | Experiment variants. If not specified, defaults to a 50/50 control/test split. |
| minimum_detectable_effect | number | Minimum detectable effect as a percentage. Lower values need more users but catch smaller changes. Suggest 20–30% for most experiments. |
| rollout_percentage | number | Overall rollout percentage (0-100). Controls what fraction of all users enter the experiment. Users outside the rollout never see any variant and are excluded from analysis. Default: 100. |
