Structural Stability, Failure-Preserving Replay, and Runtime Governance: Public Research Notes v1

This public research note package collects non-confidential working materials on structural stability modeling, failure-preserving replay protocols, residual-topology risk readouts, and runtime governance audit concepts. The materials are intended to support external technical feedback, baseline correction, data-route discovery, and possible collaboration. They do not claim experimental validation, institutional endorsement, or proof of a new physical theory.
