Writer+reader co-design rules for every file another process polls (bridge_state.json, inbox/outbox, journal, batch and scenario results) across the Python host and the C# editor package, including Windows sharing-violation behavior and version-skew tolerance.

Rules for Python host code (templates/*.py, root launchers, tests) so every change runs identically on Windows, Ubuntu, and macOS the first time — host detection, path flavor, subprocess discipline, UTF-8, process replacement, and platform-portable test expectations.

Rules for bash scripts, wrappers, and CI steps in this repo that must run identically on macOS, Linux, and Windows Git Bash (MSYS), plus native cmd launcher flavor rules and the bisection workflow for hangs that reproduce only in CI.

Rules for C# bridge code that runs on the Unity editor main thread (heartbeat, request pump, transport, scenario ticks) — the bridge must be invisible in the editor, so no sleeping, no unbounded blocking I/O, and fallback-over-wait on contention.

XUUnity Light Unity MCP release, tag, and CI-failure guardrails; use for version bumps, release tags, GitHub Actions failures, and follow-up fixes after CI catches platform-only regressions.

Rules and guidelines for safe process matching, liveness checking, and process termination on Windows, WSL, MSYS/Cygwin, macOS, and Linux.
