Summary

• Implement node_demo_fanout_orchestrator with deterministic dry-run provider fixtures and explicit live-provider preflight.
• Implement node_demo_cost_compute cost aggregation and node_demo_renderer_effect ASCII chart output.
• Mark the three demo node contracts implemented and add RuntimeLocal/EventBusInmemory proof coverage.

Verification

• uv run ruff check src/omnimarket/events/demo.py src/omnimarket/nodes/node_demo_cost_compute src/omnimarket/nodes/node_demo_fanout_orchestrator src/omnimarket/nodes/node_demo_renderer_effect tests/test_demo_runtime_path.py
• uv run pytest src/omnimarket/nodes/node_demo_cost_compute/tests/test_golden_chain.py src/omnimarket/nodes/node_demo_fanout_orchestrator/tests/test_golden_chain.py src/omnimarket/nodes/node_demo_renderer_effect/tests/test_golden_chain.py tests/test_demo_runtime_path.py -q

Notes

• Dry-run fixtures are provider inputs inside node_demo_fanout_orchestrator; successful demo output still flows through native OmniMarket nodes and local runtime/event-bus dispatch.
• Live runs preflight GEMINI_API_KEY and claude CLI before provider execution.
