extract-generic-space

Purpose

Infer the shared abstract relational structure common across conceptual-blend input spaces.

Input contract

required: [input_space_set]
optional: [candidate_relations, blend_goal]
constraints: [generic relations must be present in at least two input spaces]

Procedure

1. Compare roles and relations across the input spaces.
2. Keep only shared structure and mark source-specific attributes.
3. Validate the generic space against the blend goal before projection.

If the generic space supports a coherent candidate blend, consider simulate-emergent-properties as the next tactic.
