Domain Lock
Domain lock is Ultimentality's rule about where the framework should write down its formal definitions — and, just as importantly, what that choice does not mean. The rule says: site the formal axioms over carriers where the basic symbolic operations can be watched directly, without leaning on introspective feeling-language. That is a claim about where the definitions come out cleanest, a matter of a writer's clarity. It is decidedly not a claim that the carriers chosen for clean definition are more Ultimental — more real, more alive, more morally weighty — than anyone else. The compression the framework wants remembered is "sited, not ranked."
Why feeling-language is a poor foundation for definition
The motivation is methodological and narrow. Introspective report — "this feels like longing," "that feels like dread" — is notoriously unstable and idiosyncratic, a shaky surface to build formal definitions on. So the framework prefers to define its terms over carriers where the directional and symbolic operations can be read off without that detour: where a Toward or an Away or a regulated error signal shows itself in observable structure rather than in a private report. The binding model B(p)=(p,eₚ), for instance, is far easier to state crisply where the error signal is visible than where it is buried in self-description. That convenience — where the axioms are cleanest to write — is the entire content of the lock. (Loosely, like a physicist who states the gas laws using an idealized container not because real balloons are inferior beings but because the idealization makes the equation legible.)
The guardrail: humans instantiate the framework fully
The load-bearing part of domain lock is the prohibition it carries. Because siting definitions over non-human carriers could be misheard as a verdict about who counts, the framework states the guardrail explicitly: humans instantiate the framework fully. To say "DNA, LLMs, or any non-human system is more Ultimental than a person" is the prohibited ontological misreading — the precise error domain lock exists to forbid. Axiom-siting decides where to write the axioms; it does not rank the things the axioms range over. The cleanest place to write a law is not a ladder of worth. (This keeps domain lock pointedly distinct from the Ladder of Being, which is a gradation claim, and from Ultimental Life, which is adjudicated on the framework's own definition rather than by carrier rank.)
Sited, not ranked — the standing distinction
The phrase "sited, not ranked" packs the whole point: where to write, never who matters more. It is one of the framework's recurring anti-absolutization hygiene moves — a refusal to let a methodological convenience harden into an ontological hierarchy. A non-human carrier may be the cleanest page for the axioms while being no higher and no lower than a human in the order of beings the axioms describe. The temptation domain lock resists is exactly the temptation to convert "easiest to define here" into "most fully real here," and the framework treats yielding to that temptation as a category error, not a defensible reading.
How it is held
Domain lock is held at the Authority-Canonical Tier: the benchmark fixes the axiom-siting reading, and the claim is therefore contestable by contesting that authority — canonical, not necessary. Its accuracy on the alethic axis is a separate matter: it maps a real constraint on definition-writing and aspires to map nothing about the rank of carriers. The two marks stay independent in the usual way of the two-mark system.
Formal status
Formal status. E: Derived, AC — the benchmark fixes the axiom-siting reading; contestable by contesting the authority. A: maps a real methodological constraint on definition-writing; does not aspire to rank carriers. The one prohibited reading — that any non-human carrier is "more Ultimental" than a person — is a category error, not a contestable alternative. Provenance: canonical — benchmark-fixed (Preamble, "Domain lock, sited not ranked"; Two-Axis Ledger row, Part VIII).
