Q-PI-03: Optimum Agent Harness Per Node Role

Which agent harness (Pi, Hermes, OpenCode, raw LangChain) is optimal for each node type (research, design, development, review) given Pi 4 constraints? Does the answer change per-unit vs per-node? - Source: [[langgraph-tool-execution-tradeoffs]] - Depends on: Q-PI-02, testing each harness on each node type

Q-PI-04: Docker Container Shape for Game Runtime

Does the game backend (LangGraph + renderer + agents) run in the existing d3-tui-pi-teams-proto container, a new container, or directly on the Pi host? What bind mounts, ports, and resource limits? - Source: [[langgraph-game-surface]] - Depends on: Q-PI-01, Q-PI-02

Q-PI-05: Checkpointer Backend on Pi

Which LangGraph checkpointer (MemorySaver, SqliteSaver, PostgresSaver) is appropriate for game state persistence on Pi 4? MemorySaver loses state on restart; SqliteSaver may have concurrency issues with multiple console clients. - Source: [[langgraph-game-surface]] - Depends on: concurrent access patterns
