# deleteSetting

> Delete a stored setting value at the given scope, causing the effective value to revert to the next level in the scope hierarchy (for example, removing a per-channel override exposes the workspace-level default). Returns the value that was removed in `previousSetting`, or null if no explicit value was stored at that scope. This operation is idempotent — deleting a setting that does not exist returns null without an error.
