Heterocrystalline chimeric technology: topology-gated multiphysics and risk-aware inverse design

A heterocrystal has been proposed as a structural state whose order is carried by the extensive incompatibility of inequivalent local cells or crystalline and non-crystalline environments. Here we derive the technology theory that follows from, but is distinct from, that foundational state theory. Heterocrystalline chimeric technology (HCT) couples the direct-sum unit-cell rupture field to conserved structural evolution, mechanics and response fields, and imposes a non-negotiable topology gate: local rupture, a selected finite wavevector, persistent interfaces and bicontinuity must coexist before a chimeric functional score is admitted. A 143-point dimensionless non-local phase-field sweep coupled to an interface-conductivity boundary-value problem yields only 7 strictly gated structures. The best continuous-score surrogate is topologically fragile, passing one of five independent-seed validations, whereas an ensemble risk objective selects a different design that passes four of five. The wide binomial intervals delimit the result as a mechanistic demonstration rather than a reliability certificate. A source-resolved audit anchors four work packages—crystal–amorphous mechanics, pseudo-field and ferroelectric devices, bionic and membrane networks, and superionic composites—while keeping proposed performance thresholds separate from observations. The theory predicts intervention experiments at fixed composition and rupture density: destroying connectivity must collapse the non-additive response. HCT thereby turns the heterocrystal state variable into an auditable design programme in which topology and reproducibility are primary material coordinates.
