scores:
- name: definition_precision
  value: 4.0
  max_value: 5.0
  rationale: The definition clearly articulates a specific economic mechanism - the
    dual advantage of receiving transportation costs in selling prices while saving
    them in purchases. The concept is well-bounded and non-circular, though it could
    be slightly more precise about the exact mechanics of how this value transfer
    occurs.
- name: source_grounding
  value: 5.0
  max_value: 5.0
  rationale: This concept is directly grounded in Smith's analysis in Book III, Chapter
    1, where he explicitly discusses how proximity to towns affects both selling and
    purchasing advantages for rural producers. The entity accurately captures Smith's
    reasoning about spatial economic advantages without introducing foreign concepts.
- name: domain_placement
  value: 5.0
  max_value: 5.0
  rationale: The "Exchange" domain is perfectly appropriate, as this concept fundamentally
    concerns how market proximity affects the terms and costs of exchange transactions.
    The spatial dimension of exchange relationships is central to this concept's explanatory
    power.
- name: vsm_relevance
  value: 3.0
  max_value: 5.0
  rationale: This entity has moderate VSM relevance, potentially mapping to S4 (intelligence/environmental
    adaptation) as it describes how economic actors adapt to their spatial environment
    to gain advantages. However, it's more of a structural economic relationship than
    a clear cybernetic function.
- name: explanatory_value
  value: 5.0
  max_value: 5.0
  rationale: This entity provides excellent explanatory power by illuminating a specific
    mechanism that drives spatial economic inequality and land value differentials.
    It explains not just what happens (higher land values near towns) but precisely
    why it happens through the dual savings/revenue mechanism.

# Evaluation: Carriage Value Savings

## definition_precision — 4.0 / 5.0

The definition clearly articulates a specific economic mechanism - the dual advantage of receiving transportation costs in selling prices while saving them in purchases. The concept is well-bounded and non-circular, though it could be slightly more precise about the exact mechanics of how this value transfer occurs.

## source_grounding — 5.0 / 5.0

This concept is directly grounded in Smith's analysis in Book III, Chapter 1, where he explicitly discusses how proximity to towns affects both selling and purchasing advantages for rural producers. The entity accurately captures Smith's reasoning about spatial economic advantages without introducing foreign concepts.

## domain_placement — 5.0 / 5.0

The "Exchange" domain is perfectly appropriate, as this concept fundamentally concerns how market proximity affects the terms and costs of exchange transactions. The spatial dimension of exchange relationships is central to this concept's explanatory power.

## vsm_relevance — 3.0 / 5.0

This entity has moderate VSM relevance, potentially mapping to S4 (intelligence/environmental adaptation) as it describes how economic actors adapt to their spatial environment to gain advantages. However, it's more of a structural economic relationship than a clear cybernetic function.

## explanatory_value — 5.0 / 5.0

This entity provides excellent explanatory power by illuminating a specific mechanism that drives spatial economic inequality and land value differentials. It explains not just what happens (higher land values near towns) but precisely why it happens through the dual savings/revenue mechanism.
