resolveProxmoxHostSlug trusted attributes.host verbatim, so a value polluted with prose — lxc:teddycloud carried host="hubris (confirmed via pct config…)" — became a slug that never resolved, leaving its checks 'down' despite a correct `hosts` edge. Treat an attribute containing whitespace/parens as invalid and fall back to the canonical hosts edge. The audit now reports `polluted_attrs` — entities whose routing-critical attributes carry prose — so this class is visible instead of a silent resolution failure.
