Nico a2bc6347fc v0.13.0: Graph engine, versioned nodes, S3* audit, DB tools, Cytoscape
Architecture:
- Graph engine (engine.py) loads graph definitions, instantiates nodes
- Versioned nodes: input_v1, thinker_v1, output_v1, memorizer_v1, director_v1
- NODE_REGISTRY for dynamic node lookup by name
- Graph API: /api/graph/active, /api/graph/list, /api/graph/switch
- Graph definition: graphs/v1_current.py (7 nodes, 13 edges, 3 edge types)

S3* Audit system:
- Workspace mismatch detection (server vs browser controls)
- Code-without-tools retry (Thinker wrote code but no tool calls)
- Intent-without-action retry (request intent but Thinker only produced text)
- Dashboard feedback: browser sends workspace state on every message
- Sensor continuous comparison on 5s tick

State machines:
- create_machine / add_state / reset_machine / destroy_machine via function calling
- Local transitions (go:) resolve without LLM round-trip
- Button persistence across turns

Database tools:
- query_db tool via pymysql to MariaDB K3s pod (eras2_production)
- Table rendering in workspace (tab-separated parsing)
- Director pre-planning with Opus for complex data requests
- Error retry with corrected SQL

Frontend:
- Cytoscape.js pipeline graph with real-time node animations
- Overlay scrollbars (CSS-only, no reflow)
- Tool call/result trace events
- S3* audit events in trace

Testing:
- 167 integration tests (11 test suites)
- 22 node-level unit tests (test_nodes/)
- Three test levels: node unit, graph integration, scenario
