PM Bundle darwin-arm64 lane failed verify: b10679's macos-arm64
llama binaries link librdma.dylib which doesn't exist on macOS — a
broken upstream release. 10362 was the known-good committed state that
passed every bundle lane. config_defaults' b10679 rolling tag is
aspirational; re-pin 10679 only when a darwin-working tag exists.
5890f3bbe3's re-pin was wrong — reverted.
