Remove 3 redundant hardcoded nodes (Standard/VACE/LoRA), keeping only the Dynamic node. Add total_sequences INT output (slot 0) for loop counting. Add structured error handling: _fetch_json returns typed error dicts, load_dynamic raises RuntimeError with descriptive messages, JS shows red border/title on errors. Add 500ms debounced auto-refresh on widget changes. Add 404s for missing project/file in API endpoints. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
