📋 Decision Context

Question:

Computer Use 500 error: rootfs image never built on Hetzner server

Task: Not specified

🎯 Decision Made

Chosen:

Root cause: rootfs image never built. Added pre-flight checks + diagnostic health endpoint

Options Considered:

• No alternatives documented

💭 Reasoning

provision-server.sh only downloads kernel, lists build-rootfs.sh as separate manual step. VM times out because Firecracker has no rootfs to boot from. Added fs.existsSync checks for fast-fail with actionable errors, enhanced /health to show vmPrerequisites status.
