This minimal AArch64 launcher calls execve on the guest path supplied as argv[1]. The child receives that path as its own argv[0], retains any remaining arguments, and inherits the launcher's environment. It provides a generic acceptance bridge for running an ELF produced inside a persisted Binarrow filesystem without adding a host-side extraction operation.

Build the deterministic static launcher:

guest-tests/exec-from-filesystem/build.sh

Zig caches stay under the repository's ignored .tmp directory. The generated launcher is checked in so normal tests do not require Zig.
