Address whole-project architecture + product reviews (todo §5): make readRoles transitive so group→role grants reach the JWT (matches the Roles 'Effective access' view + OPL model; per-login only), per the user's call; add a zero-JS server-rendered confirm step for delete user/group/role (views/admin/confirm.ejs + shared buildConfirmModel; the Delete control is now a GET link, the delete stays a CSRF-guarded POST); self-lockout guards — no self-delete/deactivate (Users), no self-revoke of the direct admin grant + no delete of the admin role (Roles), each → 400 + inline error (direct-grant paths incl. the seeded admin; group-only-admin lockout = robust last-effective-admin check deferred §9); extract the gate+CSRF preamble copied across the 3 admin handlers into admin-nav.ts requireAdmin/guardedForm; shellUser keeps the email (name = local part, full email beneath). Reviewers: architecture no Critical/High, product 2 Critical + 1 High (all fixed). Deferred (scoped): host route-table→§6, list/template dedup→§5 cleanup, success-flash/empty-states/dangling-refs→§5 polish/§8, safeUrl→§7, 413/https/§N-drift→§9. Tests-first (extended the 3 admin HTTP tests + login/shell-context units); typecheck + 244 units + 8 visual + auth-refresh E2E green; stability-reviewer APPROVE
