DC-048: multi-user bootstrap + admin invites (opt-in)
Implements the user-store + invite-store + admin routes. The whole system is opt-in via siteConfig.authProviders.email.enabled = true; single-user TOTP-only installs see zero behavior change. Backend: - src/security/user-store.js: users + allowlist + bootstrap sentinel, atomic writes, last-admin protection, defensive dataDir resolver. - src/security/invite-store.js: single-use tokens (SHA-256 hashed on disk), TTL, auto-prune, defensive dataDir resolver. - routes/auth/admin.js: /me, /admin/users (CRUD), /admin/allowlist, /admin/invites (CRUD), public /invites/:token (peek + accept). - routes/auth/index.js: wires userStore, gates admin router on email auth being enabled. - src/auth/providers/email.js: verify() enforces allowlist, creates user record, tags req.user; default-enabled flipped to opt-in. - src/auth/providers/totp.js: bootstraps system@totp.local admin on first verify so current DNS2 operator shows in /admin/users. - src/security/audit-logger.js: middleware adds userId/userEmail/ userRole/viaProvider to log details when req.user is tagged. - PUBLIC_ROUTES + CSRF allowlists updated for invite redemption. Frontend: - status/js/admin.js: modal overlay with users list (role-edit, delete), invite form (email/role/TTL), copy-link button, outstanding-invites list with revoke. Exports window.AdminPanel. - status/js/core/init.js: calls AdminPanel.attachTrigger so the Admin button only appears when /me returns isAdmin=true. Tests: 35 new tests across 3 files (user-store, invite-store, auth multistore integration). Full suite: 1298/1298 passing. Docs: BACKLOG.md marks DC-048 done. CHANGELOG.md [Unreleased] section gets the DC-048 entry.

/**
|
||||
* Tests for user-store (DC-048).
|
||||
* Coverage:
|
||||
* - bootstrap rule: first user becomes admin
|
||||
* - allowlist enforcement: emails not on the list are rejected
|
||||
* - login idempotency: existing user just bumps counters
|
||||
* - role updates with valid/invalid roles
|
||||
* - last-admin protection: cannot delete the only admin
|
||||
* - concurrent login safety: mutex serializes
|
||||
* - file persistence: writes are atomic and survive process kill
