audit-structural-equivalence SKILL.md skillA
audit-structural-equivalence from yogsoth-ai/de-anthropocentric-research-engine is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add yogsoth-ai/de-anthropocentric-research-engine/audit-structural-equivalence@git:20260923.cbc38aaPins git:20260923.cbc38aa in mdr.lock. Pin the fingerprint instead.

Audit a claimed isomorphism/equivalence by constructing an explicit mapping, testing which structures/operations/invariants are preserved, searching counterexamples, and downgrading the claim to the strongest defensible relation when full isomorphism fails.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# audit-structural-equivalence
## Purpose
Audit a claimed isomorphism or equivalence and downgrade it to the strongest defensible relation when preservation fails.
## Input contract
```yaml
mode_contracts:
isomorphism: &structural_audit_input
required: [source_structure, target_structure, equivalence_claim]
optional: [required_invariants, operations, constraints]
constraints: [mapping_domains_and_preservation_obligations_must_be_explicit]
substructure: *structural_audit_input
homomorphism: *structural_audit_input
shared-invariant: *structural_audit_input
analogy: *structural_audit_input
```
## Execution protocol
Do not perform called SOP operations inline; each loaded SOP owns its contract and thresholds.
1. You MUST load skill `extract-structural-mapping` to construct the object, relation, operation, and invariant mapping.
2. You MUST load skill `test-structure-preservation` to test preservation. You MUST load skill `generate-counterexample` to search minimal counterexamples.
3. You MUST load skill `downgrade-equivalence-claim` to downgrade the claim and record lost invariants.

How to install
mdr add yogsoth-ai/de-anthropocentric-research-engine/audit-structural-equivalence@sha256:11c63b40d55c0b1bThe line at the top of this page pins the label git:20260923.cbc38aa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
