Every one of these manifests states a capability the previous release did not.
mcpp resolves the target side per layer after the dependency graph is known and
reads which layer a package fills from its capabilities; the index serves
published tarballs rather than branches, so without these entries a consumer
resolving by version gets content in which no package declares a layer and the
engine resolves the target side to the compiler payload.

openkal-llvm-runtime had no descriptor at all. It is the entry point for a
program that reaches several machines from one source -- it names the C library,
which selects the platform implementation, which names the specification -- so
its absence meant that path was reachable only through a git reference, which
is not a supported way to depend on a package.

Every CN mirror object was fetched and compared against the GitHub archive
before its entry was written here; all nine are byte-identical.
