A ConfigSegment is a reusable audience of an environment: subjects listed by id, and conditions over the evaluation context. Flag rules refer to it with IN_SEGMENT, so one change to the audience reaches every flag.

**Service** Sylphx Config · **Resource type** `config.sylphx.com/ConfigSegment` · **Name pattern** `orgs/{org}/projects/{project}/envs/{env}/config_segments/{config_segment}` · **Shape** `spec_status`
