Research direction

Start with the build command's container.inspection flow and the ptrace monitor path shown in the failure output. Reproduce the fork/exec /entrypoint.sh: no such file or directory failure if possible, then trace how the inspector handles the error. Done means failed analyses no longer leave the analysis containers running.
