Why: stage 7 (DR6-DR10) requires repeatable browser evidence; the reviewed flows lacked a disable confirmation, role-scoped draft lifetime with an explicit leave decision, and status announcements.
Evidence: 16/16 deterministic Playwright scenarios pass on an isolated preview (route-driven, no live services); 283 unit tests and build/knip stay green; live-layer cases ride the same file under IAM_E2E_LIVE.
Impact: RolePermissionsPanel keeps per-roleId drafts, guards zone leave/refresh, adds a disable confirm strip (name + binding count + impact + cancel) and restores save focus; AdminZone consults the leave guard; AccountUsersPanel notice becomes role=status; new e2e/iam-role-authority.playwright.ts.
