The load-bearing design decisions of Plenum (smart-thermostat-with-vents), the invariants that must hold, WHY each exists, and the known-weak points. Load when you need the canonical temperature-unit contract (°F storage, single write boundary, #231), the component map with real file paths, the cycle-engine invariants (mode lock, in-place trigger updates, 60s tick), the MCP loopback design, or a "
