Bridge Validation

Validate analogy depth and transfer viability before committing resources to transfer.

Stages

Stage 1: Analogy Quality Assessment

Apply analogy-quality-assessment SOP to each candidate analogy. Classify depth:

• Surface: Shared object attributes only (e.g., "both are round") — REJECT
• Structural: Shared relational structure (e.g., "both use negative feedback to maintain homeostasis") — ACCEPT
• Systemic: Shared higher-order constraints and causal structure — STRONG ACCEPT

Stage 2: Transfer Adaptation

For accepted analogies, test transfer viability using transfer-adaptation SOP:

• Can the principle be stated independently of source domain?
• Does the target domain have the necessary substrate for the principle?
• What adaptations are needed to fit target constraints?

Stage 3: Structural Consistency Check

Verify the adapted transfer maintains structural consistency:

• Mapped relations preserve directionality
• Higher-order constraints are respected
• No critical source elements are unmapped without justification
• The transfer does not violate known target domain physics/logic

Available SOPs

structural-mapping	Stage 3 — verify structural consistency
abstraction-extraction	Support — re-abstract if mapping fails

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
analogy-quality-assessment	Assess analogy depth (surface/structural/systemic). Determines whether an analogy warrants transfer investment.
structural-mapping	Map source→target structural correspondences. Identifies corresponding, missing, and extra elements between domains.
transfer-adaptation	Adapt transferred principle to target problem constraints. Produces concrete adapted solutions from abstract principles.
