step `{label}` failed (status {}): {tail}

Error message

step `{label}` failed (status {}): {tail}

What it means

A Kompress provisioning python step exited non-zero; the message embeds the exit status and the last 800 chars of its stderr, which names the actual failure (pip resolution error, OOM, model download failure).

Solutions

1. Read the embedded stderr tail to identify the failing step
2. Fix the named cause (network, disk space, dependency conflict) and re-run provisioning
3. Clear the partial venv so provisioning starts clean
