This directory contains developer and operator utilities that do not belong to one runtime component or one guest-OS backend.

• add-spdx-attribution.py updates SPDX attribution metadata.
• mock-cf-dns-api/ provides a local Cloudflare DNS API test double.
• sca/ builds self-contained application images.
• dev-stack.sh preserves the unsupported legacy all-in-one host, guest, and deployment helper.
• vm-runner/ preserves the unsupported legacy direct-QEMU runner and GPU passthrough helper.

The legacy tools are kept out of os/yocto/ because they cross host, guest, and deployment boundaries. Use the Rust dstack and dstackup CLIs for supported workflows.
