scores:
- name: definition_precision
  value: 4.0
  max_value: 5.0
  rationale: The definition clearly articulates a specific spatial-economic concept
    about how market access decreases with distance from trade centers, creating measurable
    gradients of opportunity. The concept is well-bounded and avoids circularity,
    though it could be slightly more precise about what constitutes "major trade centres."
- name: source_grounding
  value: 5.0
  max_value: 5.0
  rationale: This entity is directly grounded in Smith's explicit analysis in Book
    I, Chapter 3, where he describes how industry develops sequentially from coasts
    and rivers to inland areas and finally remote regions. The concept captures a
    clear pattern that Smith identifies and explains in the source text.
- name: domain_placement
  value: 5.0
  max_value: 5.0
  rationale: The "Exchange" domain is perfectly appropriate since this concept fundamentally
    concerns how geographic proximity to markets affects trade opportunities and economic
    transactions. The accessibility gradient directly shapes patterns of exchange
    and market participation.
- name: vsm_relevance
  value: 3.0
  max_value: 5.0
  rationale: This entity has moderate VSM relevance, primarily mapping to S4 (intelligence/environmental
    adaptation) as it describes how economic systems adapt to their geographic environment
    and information flows. However, it's somewhat abstract and doesn't clearly align
    with operational VSM functions.
- name: explanatory_value
  value: 4.0
  max_value: 5.0
  rationale: The entity provides strong explanatory power by illuminating the structural
    mechanism behind uneven economic development patterns that Smith observes. It
    explains why certain regions develop specialized industries while others remain
    primarily agricultural, revealing the spatial logic of market-driven development.

# Evaluation: Economic Accessibility Gradient

## definition_precision — 4.0 / 5.0

The definition clearly articulates a specific spatial-economic concept about how market access decreases with distance from trade centers, creating measurable gradients of opportunity. The concept is well-bounded and avoids circularity, though it could be slightly more precise about what constitutes "major trade centres."

## source_grounding — 5.0 / 5.0

This entity is directly grounded in Smith's explicit analysis in Book I, Chapter 3, where he describes how industry develops sequentially from coasts and rivers to inland areas and finally remote regions. The concept captures a clear pattern that Smith identifies and explains in the source text.

## domain_placement — 5.0 / 5.0

The "Exchange" domain is perfectly appropriate since this concept fundamentally concerns how geographic proximity to markets affects trade opportunities and economic transactions. The accessibility gradient directly shapes patterns of exchange and market participation.

## vsm_relevance — 3.0 / 5.0

This entity has moderate VSM relevance, primarily mapping to S4 (intelligence/environmental adaptation) as it describes how economic systems adapt to their geographic environment and information flows. However, it's somewhat abstract and doesn't clearly align with operational VSM functions.

## explanatory_value — 4.0 / 5.0

The entity provides strong explanatory power by illuminating the structural mechanism behind uneven economic development patterns that Smith observes. It explains why certain regions develop specialized industries while others remain primarily agricultural, revealing the spatial logic of market-driven development.
