- Rate limiter tracks failures only; success resets counter
- Record failures/successes after password verification, not before
- WebAuthn rp_id/origin resolved dynamically from request domain
- Management domains auto-discovered from nginx backend config
- All WebAuthn operations validate domain against management list
- Add GET /api/auth/webauthn/capable endpoint for frontend checks
- Frontend checkWebAuthnCapable() function for domain-gated UI
- Timing side-channel fix: pre-compute dummy hash at module load
- Builtin admin seeded with random password (logged at WARNING)
- Logout handler returns consistent response shape
- update_permissions now calls blacklist_active_refresh_token and
rotate_user_secret to immediately invalidate stale tokens
- create_user uses returned id from tx.run_one instead of redundant SELECT
- websocket reconnect explicitly closes old connection after token refresh
to prevent onclose handler race condition
