Game::StrategyAIAgent::Streamable typed end to end. The writer is entirely
unconditional; the branch the decompiler shows is an inlined vector destructor
whose operator delete is marked noreturn. dsh is a std::map's _Mysize, so it is
the (pid, trns) count and not a scalar; lnat and lat are scalars, not elements.
AISystem::Write never reads its object, so every AISys body on disk is empty
regardless of game state. StreamableEnum<T> is a frame holding one int, which
makes SysMem/mts/nalat arrays of frames rather than of ints.
Named coverage 98.0% -> 99.9% on all four saves; state_checksum.py unchanged
and still PROVED. Section 7 lists the ten element layouts no save exercises and
says what workload would settle each.
