+-- libc++ and libc++abi as a SOURCE package, for a hosted target whose toolchain
+-- payload cannot supply a static libc++ built for that target.
+--
+-- THE CASE THAT CREATED IT. mcpp's LLVM payload ships libc++ headers, a std
+-- module source and static archives built for the machine the payload runs on.
+-- On the iOS rows the archives are macOS objects and ld64 refuses them, so the
+-- engine linked the SDK's libc++ under the payload's newer headers, and an
+-- inline function in libc++ 22's headers referenced a symbol the SDK's libc++
+-- 19 does not export (`__hash_memory`; mcpp-community/mcpp#630). A standard
+-- library is configured for one C library and compiled against its headers;
+-- this package carries the whole library, so the headers a unit is compiled
+-- against, the module it imports and the objects it links are one release.
+--
+-- THE MECHANISM IS THE ONE `openkal-llvm-runtime` USES: `provides` declares the
+-- C++ layer, the engine broadcasts the headers, adopts the std module, and
+-- links with `-nostdlib++`. The C library beneath stays the target's own, and
+-- nothing here is Apple-specific.
+--
+-- THE NAMESPACE AND THE VERSION ARE UPSTREAM'S, as `llvm.compiler-rt-builtins`
+-- established: every file under llvm/ is byte-identical to `llvmorg-22.1.8`,
+-- and the fourth segment is the packaging revision. A consumer writes the
+-- version out in full, because a bare requirement in mcpp is an exact pin.
