Why
Contributors need to know which of the three languages a change touches without reading the code.
How
qdp/DEVELOPMENT.md: an architecture section (what each layer owns), a "which files do I touch" table, the three-file recipe for adding an encoding, and how to guard performance withbaseline.py. The no-CUDA pre-push check uses a separate target directory so it does not invalidate the normal build cache.qdp/Makefile:make check-kernelsresolves every embedded kernel symbol and smoke-launches one;make parityruns the cross-backend grid.Checklist
