“Agent based class design”
summary
Proposes decomposing classes into small agents that publish capabilities and requirements and uses C++14 template metaprogramming to auto-wire them so valid combos produce zero-cost, statically linked objects. Implements a compose/arena model and a tiny TMP library to make assembly fast enough; embedded driver examples compile to about 10× smaller flash and save RAM versus vendor C code. Proof-of-concept widgets, UART and text-conversion agents exist, shared_ptr decomposition is sketched but not yet fully implemented.
