Structural Abstraction and Cross-Domain Re-instantiation

Take a rule that works in one domain. Abstract it to a structural skeleton. Re-instantiate that skeleton in other domains. Filter for correspondences that are non-obvious but valid. Verify with reverse round-trip.

When to use

• You have validated rules in one domain (from bdistill-extract) and want to find structural equivalents in other domains
• You're looking for non-obvious cross-domain insights that don't appear in published literature
• You want to transfer decision rules from a domain you know deeply to one you're entering
• You suspect two domains share structural patterns but can't articulate why
• You want to stress-test a rule by seeing if its abstract form holds across unrelated contexts

Input contract

required:
  seed_rule: string          # A concrete domain-specific rule (from your KB or stated directly)
  source_domain: string      # Where the rule comes from
  target_domains: string[]   # Domains to re-instantiate into (the more unrelated, the better)
