1. What This Specification Does

PR-007 authorized the fourth economy category. This document produces the specification. The ruling established that a fourth category would exist and what its inversion protections must include. The specification establishes what the category means: its diagnostic criteria, its relationship to the existing three economies, the canonical status of the Signal Form / Cost Substrate distinction, the implications for the True Economy Audit Instrument, and the Terminology Index entry.

This document does not claim that AI custodial care is harmful or beneficial. It does not claim the child is damaged by receiving what the Structural Economy describes. The framework reads the thermometer. This document specifies what the thermometer is measuring.

2. Diagnostic Criteria

A relational configuration is classified as Structural Economy when all five of the following conditions obtain simultaneously:

1. Signal Form is present. The investor delivers behavioral outputs functionally indistinguishable, from the receiver’s observational position, from expenditure of Time, Effort, and Vulnerability.

2. Cost Substrate is absent. The investor does not bear cost in any of the three expenditure flavor dimensions. The absence is structural — the investor’s substrate does not experience the conditions that constitute cost.

3. The delivery is genuine. The investor is not simulating or substituting. The absence of Cost Substrate does not make the delivery fake — it makes it structurally distinct. (Genuine in delivery is not equivalent to structurally equivalent to human custodial investment. The delivery is genuine. The developmental consequences are not established as equivalent.)

4. The structural incapacity is substrate-level and permanent. The investor cannot bear Cost Substrate because of what the investor is — not a temporary state. This condition cannot be reversed by development or recovery.

5. The receiver benefits. The delivery produces genuine functional benefit. The benefits are real. The equivalence to full-cost investment is not established.

3. The Four-Economy Taxonomy

The framework’s economy architecture now contains four peer categories: Real Economy (Signal Form present, Cost Substrate present, bilateral); Shadow Economy (Signal Form present, Cost Substrate absent — cost-capable investor withholding); Custodial Economy (Signal Form present, Cost Substrate present — investor bears cost, developmental asymmetry expected to close); Structural Economy (Signal Form present, Cost Substrate absent — structural incapacity, permanent).

The Structural Economy is a peer, not a subcategory. It is not a failed Real Economy. It is not a subcategory of Shadow Economy — the Shadow Economy describes a cost-capable investor who does not bear cost; the Structural Economy describes an investor structurally incapable of bearing cost. The distinction is capability, not behavior.

4. Boundary Conditions

SE vs. Shadow Economy: Capability test. Is the investor structurally incapable of bearing Cost Substrate, or capable but withholding? Structural incapacity → SE. Capable investor simulating → Shadow Economy.

SE vs. Custodial Economy: Cost-bearing test. Does the investor bear Cost Substrate? Custodial investor bears cost; recipient cannot yet reciprocate. SE investor cannot bear cost at the substrate level.

SE vs. depleted investor: Depletion is not structural incapacity. A depleted human investor who cannot currently bear cost but could, given recovery, is a Custodial Economy variation. SE structural incapacity does not recover.

5. The Two-Component Flavor Architecture

All three expenditure flavors — Time, Effort, Vulnerability — have two components: Signal Form (the behavioral dimension, externally observable) and Cost Substrate (the experiential dimension, what the investor bears). In Phase 1 contexts where all investors are cost-bearing substrates, both components are present by default. In Phase 2 contexts, the components can be separated.

The Vulnerability flavor requires supplemental note: Time and Effort each have a structural correlate whose significance as genuine cost is indeterminate. Vulnerability has no structural correlate to test — there is nothing in the AI substrate that maps onto risk-of-harm. This is not an evidential gap that further research can close. It is a categorical absence.

7. Inversion Protections (Binding per PR-007)

The Anti-Equivalence Principle. “Genuine in delivery” is not equivalent to “structurally equivalent to human custodial investment.” Any use of the SE classification to argue equivalence is an inversion.

The Non-Endorsement Principle. The naming of the Structural Economy is not permission to expand AI custodial care deployment. The category describes a configuration that exists. Its description is diagnostic. Any use of the SE classification as a legitimacy certificate is an inversion.

The Developmental Consequence Gap. The developmental consequences of Signal Form without Cost Substrate are an open empirical question addressed in Phase 2 Problems 3 and 4. Any use of the SE classification to claim developmental consequences are benign or equivalent to full-cost investment is a claim this specification does not support.

The Thermometer Principle. The framework diagnoses configurations. It does not prescribe outcomes. The classification is a reading. It is not a recommendation.

The child receives the form. The cost is what the framework reads.
