Library Selection

Treat a library as part of the firmware and hardware contract. A popular package that compiles for one architecture may still use incompatible pins, timers, memory, bus assumptions, or APIs on another.

Intake

Record exact board/module, architecture, Arduino core or vendor SDK, compiler, toolchain, required API, bus/pin constraints, memory budget, license boundary, update policy, and whether the device is connected or field-updatable.
