Mirror the crafter-build pipeline in a plain GNU Makefile — precompile the libc++ std module and the Imsd partitions in dependency order, archive imsd-core, link the three executables with the same clang/ libc++ flags — so distributions can build from source without packaging crafter-build first. make check runs the same 7 suites; make install stages the binaries plus the packaging/ files under DESTDIR/PREFIX. Rewrite packaging/APKBUILD from a documentation skeleton into a real source-build APKBUILD on top of it (Alpine's llvm-runtimes ships the std module sources since 22.x). project.cpp remains the canonical build description.
