Layer 1: Pi — Hardware, Runtime, Agent Harnesses

The infrastructure layer. What the game runs ON.

Q-PI-01: LangGraph Compile Time on Pi 4

At what map size does LangGraph compile time become a practical blocker on Pi 4 hardware? 10x10 hex? 50x50? 100x100? - Source: [[langgraph-hex-node-mapping]] - Depends on: actual benchmarking

Q-PI-02: Bun→Python Subprocess Overhead

How much does invoking a Pi agent (Bun/JS) from within a LangGraph node (Python) cost per turn on a Pi 4 — subprocess spawn vs HTTP vs IPC? - Source: [[langgraph-tool-execution-tradeoffs]] - Depends on: benchmarking subprocess vs HTTP latency
