Paper 20 — Domain Design Reference Infrastructures in the AI+AGI Era: Hard-Tech, Built-Environment, Robotics, and Infrastructure Design as Non-Executable Coordinate-Reference Structures

This working paper develops Domain Design Reference Infrastructures as non-executable coordinate-reference structures for high-consequence design domains in the AI and AGI era. Generative systems increasingly produce or assist with semiconductor design artifacts, quantum circuit candidates, robotic design records, architectural drawings, BIM models, civil engineering drawings, infrastructure plans, plant layouts, facility records, safety references, inspection notes, and construction-related documentation. These artifacts may be valuable for human review, institutional coordination, technical comparison, preservation, cross-verification, economic reference, or later public-authority consideration. The framework positions domain design artifacts as coordinate-referable design reference objects, design candidate outputs, domain condition boundaries, verification records, human review records, time-history references, post-cloud preservation references, external execution environment references, and economic or contribution reference objects. The proposed framework does not manufacture semiconductors, operate electronic design automation tools, execute quantum circuits, control qubits, drive robotic motion, approve buildings, issue permits, construct facilities, certify safety, validate engineering correctness, calculate value, transfer assets, settle payments, or generate legal effect. Its contribution is a cross-domain structural vocabulary for treating design artifacts as referable, reviewable, preservable, and boundary-aligned before external engineering, construction, manufacturing, public-authority, regulatory, economic, safety, or operational processes act upon them. This working paper is Paper 20 of the AGI Structural Alignment Series.
