SupportsCLAIM-142 — Two communicative realizations can agree on every probe in a restricted family without being structurally identical, so observational equivalence is relative to the probes, and only independently justified probes evaluated on held-out cases are evidence that structure was preserved, CLAIM-206 — If a communicative kind can outrun every probe, human same-kind judgements, themselves one probe family, can neither confirm nor defeat the October thesis; if it cannot, the kind does in the tests only what an observational class does, which the record's term for a kind says it is not, CLAIM-247 — The bearer of communicative identity reversed, from an operational object defined on observed responses to a kind that can outrun observation, and no turn argues the change; both stances stand in the record, CLAIM-253 — The intertwining defects are defined on unobservable interpretive-state spaces, so they are not identified from judgement data, and the commutator identity bounds observed order effects only with a further, unstated readout-intertwining defect
ComplementsCLAIM-217 — For a communicative kind, the standard of sufficiency is the uptake of competent participants who know the standings and norms in play: a defeasible standard, overridden only where the act's other constituents diverge from the judges' verdicts, so a probe family is tested against it, and a kind outruns the families coarser than that standard and the judges only through those constituents
UsesTERM-033 — fidelity, as observational equivalence over response trajectories
Cited as “rests on” byARG-029 — The operational account, kept as a rule of method, supports a realist kind that can outrun observation as the bearer of communicative identity

The claim

A39 §4.4: “different hidden-state models may produce identical observations”; “Distinguish predictive or operational equivalence from equivalence of internal representations.” A39’s preamble: the revision “prevents us from prematurely defining faithful translation as preservation of internal cognitive states we cannot observe or uniquely identify”. A39 §3.3 accordingly demoted the interpretive state: its dimensions “do not define a unique natural coordinate system”, and states are “model-dependent and potentially latent”.

Manuscript §2: “We use ‘observable’ in an operational rather than narrowly physical sense … Neither a high-level latent coordinate nor a fixed hierarchy of levels is assumed primitive. Latent variables may be learned as compressed summaries of recurring observational patterns, but their significance must be validated by predictive consequences.” §3: “An observational equivalence class identifies realizations indistinguishable by the chosen procedures.”

The owner’s U27 request to “use higher order latents to characterize the more abstract similarity” (CLAIM-008) tested this. A73 answered with latents identified “through independently testable communicative contrasts”. After U28 (CLAIM-042), A75 demoted them to “compressed representations of recurring patterns across these observational constraints. They are not the ontological foundation”, which is the manuscript’s §2 wording in substance.

What it does not say

That meaning is nothing but behaviour (CLAIM-112). Nor that states are useless: the manuscript’s §8–9 still transports state representations, which CLAIM-011 bears on.
