overall_score: 4.0
scores:
- name: definition_precision
  value: 4.0
  max_value: 5.0
  rationale: The definition is precise and specific, clearly identifying coal-heavers
    as laborers who unload coal from ships and noting their specific wage premium
    (4-5 times common labor). It captures a distinct occupational category rather
    than a vague concept.
- name: source_grounding
  value: 5.0
  max_value: 5.0
  rationale: This entity is directly grounded in Smith's text from Book I, Chapter
    10, where he explicitly discusses coal-heavers as an example of how disagreeable
    and irregular work commands higher wages. The wage multiple cited appears to come
    directly from Smith's analysis.
- name: domain_placement
  value: 4.0
  max_value: 5.0
  rationale: The "Distribution" domain is appropriate since this relates to wage determination
    and how labor compensation varies based on working conditions. However, it could
    arguably fit in a labor market or wage theory subdomain if one existed.
- name: vsm_relevance
  value: 2.0
  max_value: 5.0
  rationale: Coal-heavers represent a specific type of worker rather than a systemic
    function, making them largely VSM-neutral. They don't naturally map to any particular
    VSM system (S1-S5) as they are an empirical example rather than a structural element.
- name: explanatory_value
  value: 5.0
  max_value: 5.0
  rationale: This entity provides excellent explanatory value by illustrating the
    concrete mechanism of how multiple negative job characteristics (arduous, dirty,
    irregular) combine to drive wages significantly above market averages. It demonstrates
    Smith's theory of compensating wage differentials in action.

# Evaluation: Coal Heaver

## definition_precision — 4.0 / 5.0

The definition is precise and specific, clearly identifying coal-heavers as laborers who unload coal from ships and noting their specific wage premium (4-5 times common labor). It captures a distinct occupational category rather than a vague concept.
