Every clang++, clang and llvm-ar the tool spawned was a bare name on PATH, the std module source was /usr/share/libc++/v1/std.cppm, the WASI sysroot /usr/share/wasi-sysroot and the mingw headers /usr/x86_64-w64-mingw32, spelled out at eighteen call sites. A toolchain installed anywhere else, which is what the Flatpak ships under /app, had no way in. Crafter.Build:Toolchain resolves all of it once per process: CRAFTER_BUILD_LLVM_DIR, else a clang++ installed beside crafter-build (<prefix>/bin, found through the same walk GetCrafterBuildHome does), else PATH. What sits beside the compiler is used when present: its libclang.so, its clang-c headers, its std module source, its WASI sysroot. An explicit prefix without a clang++ is an error rather than a fallback, for the same reason CRAFTER_BUILD_LIBCLANG was already exclusive. CRAFTER_BUILD_LIBCXX_DIR points at a libc++ install other than the compiler's own, and CRAFTER_MINGW_DIR now does what its help line always claimed: it is passed as --sysroot for the mingw target. Binaries linked by a toolchain outside /usr get an rpath to its lib dir, since its libc++.so.1 is not on the loader's default path. HostTarget() is the resolved clang's -print-target-triple. A clang built without a vendor reports x86_64-unknown-linux-gnu where Arch's reports x86_64-pc-linux-gnu, so target equality that decides whether a test runs locally and which targets a bare `test` sweeps goes through SameTarget, which ignores the vendor field. The strings themselves are never rewritten: clang rejects a PCM whose triple differs from the importing unit's. The examples and README stop hardcoding the host triple; the default is already the host. `crafter-build --version` prints the version baked in at build time (CRAFTER_BUILD_VERSION, else `git describe`, else 0.0.0-dev), the compiler and the host triple, and is answered before any argument is forwarded to project.cpp. The version is a define on the library, so each version is its own library variant and relinks the executable and tests once per commit. build.sh gains a shebang and `set -eu`, honours CRAFTER_BUILD_LLVM_DIR and CRAFTER_BUILD_VERSION, skips the glslang clone when it is already there, and writes a fresh archive instead of appending to one that may hold members from an older layout.

library
A static library + an executable that consumes it.
cd examples/library
crafter-build
./bin/math-app-x86_64-pc-linux-gnu-native/math-app
Layout:
mylib/MyMath.cppm # the library's module interface
main.cpp # the consumer
project.cpp # declares both, with cfg.dependencies wiring them
Two Configuration objects: a LibraryStatic and an Executable whose dependencies points at the lib. The build runs them in parallel and links libMyMath.a into math-app automatically. import MyMath; in main.cpp resolves through the dep graph — no header paths to hand-wire.
The static unique_ptr<Configuration> for the lib is the canonical lifetime pattern: the parent's dependencies is vector<Configuration*> (raw), so something needs to keep the lib alive across the function return. File-local static does it cleanly without a global pool.
