Cross-Domain Reasoning Anchors (CDRA) proposes an observational audit framework for describing cases in which relational structure appears to remain reconstructable across changes in domain, representation, or surface form. Rather than treating transfer as the movement of literal information, the framework models anchors as transport interfaces that preserve sufficient relational structure for later reconstruction. The manuscript derives its initial observations from two previously published artifacts: Cross-Linguistic Phonetic Anchors (CLPA), which examines semantic reconstruction across languages, and Observability Collapse in Threat Intelligence Reporting (OCITI), which examines reconstruction of vulnerability state across reporting systems. From these cases, CDRA develops a vocabulary for anchors, transformations, reconstructions, and conclusions; proposes an audit protocol for evaluating candidate transfer claims; defines failure conditions; and establishes explicit research boundaries. CDRA is presented as an observational audit framework rather than a cognitive, neurological, biological, or empirical theory. Its purpose is to provide a structured method for organizing, evaluating, and challenging claims of cross-domain structural transfer.
