Whether the application is the default application for the microfrontends group
Whether observability data should be routed to this project or a root project. Can only be set for child applications.
200Success
Retention policies for deployments. These are enforced at the project level, but we also maintain an instance of this at the team level as a default policy that gets applied to new projects.
Project shape.
null on a rule list clears the project's override for that rule type (fall back to team for every env); omitting is equivalent. Setting deploymentPolicy itself to null clears every override at once. Kept structurally distinct from {@link TeamDeploymentPolicy} so the two storage locations don't share a type by accident.Password protection settings returned without the secret password hash.
Requested and authorized operations when
checkPermissions is used. Legacy includePermissions responses contain a broader, non-authoritative permission summary.Description of why a project was rolled back, and by whom. Note that lastAliasRequest contains the from/to details of the rollback.
