## New features - Configurable bottom connection points per node (1–4 handles) - Fit view on load - LiveView improvements - Node modal: inline Type/Icon picker, default icon in trigger - Remove redundant Save button from ScanConfigModal ## Scanner fixes - Phase 1: replace nmap ARP sweep with concurrent asyncio ping sweep (50 parallel pings, 1s timeout). Zero false positives, works in any Docker network mode. Supplements with /proc/net/arp for ICMP-blocked devices. - Phase 2: explicit -sS (root) / -sT (non-root) scan type; bump host-timeout to 60s; gather(return_exceptions=True) so one failing host doesn't abort the batch - Fix 404 on missing device in hide/ignore - Validate CIDR ranges to prevent nmap injection - Thread-safe cancel set, pre-fetch canvas/hidden IPs (no N+1 queries) - Logging: attach StreamHandler to root logger so app.* logs are visible ## Tests - 21 backend scanner tests (ping sweep, ARP cache, Phase 2 tolerance) - Full NodeModal coverage (53 tests) - LiveView, store, edge label tests
