The ASML Key
A policy observation that extreme-ultraviolet lithography machines are large, few and traceable, and that existing export controls on them already demonstrate the mechanism a treaty could extend. Framed as leverage analysis, not as instruction.
The ASML Key is a policy observation, not a description of a machine. The observation is that the machines used to produce leading-edge chips are large, produced in small numbers, physically distinctive, and already subject to national export controls. That combination means the leverage the Semiconductor Chokepoint identifies at the level of firms already has a working precedent at the level of machines.
What the observation is used for. The book uses it to argue that alignment-relevant export controls do not require a new legal category or a new class of enforcement. The category already exists and has already been used. That is a narrow claim: it says the mechanism a treaty (see HARI Treaty) would rely on has been demonstrated. It is not a claim about who currently uses that mechanism or in whose interest.
What the observation is not. It is not a claim about how the machines work. No description of the optical stack, the exposure sequence, the yield behaviour, or the servicing regime is offered here. Descriptions of that kind belong to the manufacturer and to the export-control regime, not to a research page.
Why naming it is useful. Policy arguments about hardware-level alignment can look abstract because the manufacturing world they name is unfamiliar. Naming the ASML Key shrinks the argument to something concrete: a specific class of machine that is already subject to state-level attention, and to which alignment-relevant conditions could in principle be added. Whether they should be is a political question. That the mechanism is already present is a factual one.
Related to the treaty stack. The ASML Key sits under the HARI Treaty as its most concrete mechanism, alongside the certification and verification apparatus described in Eden Mark Certification and IAEAI. Together they make a policy stack that runs from machine to certification to international authority to treaty.

Priority is established by the date of publication, not by credential or affiliation. This concept was first placed on the public record on 2026-01-02 (2026). Priority applies to the specific named framing under this label; where adjacent ideas have established prior art, no invention claim is made over it. See the corresponding entry in the Priority and Claims Ledger for the anchored first-publication line and any concept-specific risk notes.
