OCLM Phase 2: Adversarial Validation of Canonical Lineage Non-Substitutability

The Oracle–Child Lineage Model (OCLM) Phase 2 presents an adversarial validation campaign against the inherited Phase 1 Tamarin formal-model suite. OCLM distinguishes between a record that claims a particular history and the canonical lineage through which an entity was generated. A different record, identifier, certificate, ledger history, or consensus outcome does not become the canonical lineage of an existing Child merely by being recorded or accepted as such. Canonical continuity requires authenticated origin and succession. Under the stated symbolic models, attacker capabilities, cryptographic abstractions, and compromise conditions, the final Phase 2 evidence records: • 80 of 80 symbolic adversarial attack classes ruled out;• zero counterexample traces;• zero unresolved attack classes;• eight of eight health and reachability properties reachable; and• A48 H1, H2, H3, and the final past-epoch identity property verified together in one integrated Tamarin invocation. OCLM does not replace blockchain consensus. It is intended to operate as a higher lineage layer determining whether states accepted by different blockchains, ledgers, databases, certificate systems, or evidence systems belong to the same authenticated canonical lineage. The results apply to the exact preserved formal models and stated assumptions. They do not claim universal unbreakability, physical truth of every Oracle input, or automatic security of every implementation or deployment.
