- name: definition_precision
  value: 4.0
  max_value: 5.0
  rationale: The definition is clear and specific, distinguishing navigable rivers
    from ordinary waterways by their capacity for goods transportation and their role
    as "natural highways." It avoids circularity and captures the essential economic
    function that makes these rivers significant.

  max_value: 5.0
  rationale: This entity is directly grounded in Smith's text from Book I, Chapter
    3, where he explicitly discusses navigable rivers and provides concrete examples
    (Nile, Chinese rivers) to illustrate their economic importance. The concept emerges
    naturally from Smith's analysis rather than being imposed from external frameworks.
- name: domain_placement
  value: 5.0
  max_value: 5.0
  rationale: The placement in the "Exchange" domain is precisely correct, as navigable
    rivers fundamentally enable and expand market exchange by connecting inland producers
    to broader markets. This infrastructure directly facilitates the circulation of
    goods that Smith identifies as central to economic development.

  max_value: 5.0
  rationale: While navigable rivers could be seen as S1 infrastructure (enabling primary
    operations) or S4 elements (environmental resources that shape adaptation), they
    don't map cleanly to any single VSM system. They're more accurately understood
    as foundational infrastructure that supports multiple VSM functions rather than
    embodying a specific cybernetic role.

# Evaluation: Navigable Rivers

## definition_precision — 4.0 / 5.0

The definition is clear and specific, distinguishing navigable rivers from ordinary waterways by their capacity for goods transportation and their role as "natural highways." It avoids circularity and captures the essential economic function that makes these rivers significant.

## source_grounding — 5.0 / 5.0

This entity is directly grounded in Smith's text from Book I, Chapter 3, where he explicitly discusses navigable rivers and provides concrete examples (Nile, Chinese rivers) to illustrate their economic importance. The concept emerges naturally from Smith's analysis rather than being imposed from external frameworks.

## domain_placement — 5.0 / 5.0

The placement in the "Exchange" domain is precisely correct, as navigable rivers fundamentally enable and expand market exchange by connecting inland producers to broader markets. This infrastructure directly facilitates the circulation of goods that Smith identifies as central to economic development.

## vsm_relevance — 3.0 / 5.0

While navigable rivers could be seen as S1 infrastructure (enabling primary operations) or S4 elements (environmental resources that shape adaptation), they don't map cleanly to any single VSM system. They're more accurately understood as foundational infrastructure that supports multiple VSM functions rather than embodying a specific cybernetic role.

## explanatory_value — 5.0 / 5.0

This entity provides excellent explanatory power by illuminating the structural mechanism through which geography enables economic development—specifically how natural transportation networks extend markets inland and thereby support division of labor. It reveals a key causal relationship between physical infrastructure and economic organization.
