The lowercase `m` star designation is preserved exactly from the READ-ONLY profile and reflects an object at the hydrogen-burning minimum mass boundary. This extreme classification is incorporated into the narrative as a community-defining feature. Wave_4 for a dead-end is consistent with later settlement of less-attractive systems; the community's founding character reflects people who chose isolation deliberately.
