[§7:307–310](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/design-region-ha-two-box/docs/superpowers/specs/2026-10-15-region-ha-two-box-regions-design.md:307) now requires a persistent group role, inherited in the enrolment write, with existing members updated atomically. This fits the existing `Region` group identity and [roster conditional-write boundary](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/design-region-ha-two-box/internal/hostactors/roster.go:263): a concurrent enrolment either precedes rollback and is included, or loses the write race and must retry. §11 covers replacement both during and after rollback.
