Reviewing the detection patterns in hiveMind:

  # Subscription limit: quota/subscription exhausted (distinct from rate-limit)
  if echo "$prose" | grep -qiE 'subscription.*limit|daily.*limit.*reached|monthly.*limit|quota.*exhausted|billing.*limit|plan.*limit.*exceeded'; then
    echo "subscription-limit|none|critical"
    return 0
  fi

Source code display must NOT flag subscription-limit. prose-scrub removes
comments and grep lines. Active agent remains available.
