Device‑level weapon controls

Require consumer fabrication devices (3D printers, CNCs) to include tamper‑resistant, auditable software/hardware controls that block or log the manufacture of weapon parts, and pair that mandate with liability for manufacturers and standardized reporting for recovered fabricated firearms. — Mandating device‑level controls is a durable regulatory precedent that shifts debates from content/FILE availability to product design, enforceability, civil liability and the technical arms‑race between regulators and evaders.
