Summary

• refresh the public README around the Gemma 4 AI Agent finals narrative
• publish the finals PPT, verified demo script, technical handbook, scoring matrix, and evidence package
• add Gemma 4 + Google ADK controlled planning, hard-constraint validation, bounded recovery, and verified episodic memory
• load the longest-bridge 100 m POI result onto the map by default
• add visual county-planning Word/PDF reports, preflight checks, behavior evaluation, and real E2E scripts

Verification

• 236 finals runtime regression tests passed
• 73 finals core tests passed
• 52 model-gateway and tool-filter compatibility tests passed
• 5/5 deterministic Agent behavior contracts passed
• Ruff, Python compilation, Docker Compose parsing, PPTX/DOCX integrity, and release SHA-256 manifest passed

Evidence boundaries

• live Gemma 4 + ADK repeated evaluation measures tool selection and branch control with deterministic planning-tool responses
• the locked Bishan evidence is a real MPC run using reused prepared data and ONNX ensemble artifacts
• the county engine is described as a domain-specific GWM prototype, not a complete general-purpose geospatial world model
• historical intranet validation is not represented as a current production deployment of GIS Data Agent
