Organizes thought or workflow but is not evidence for a physical claim. checks assumptions, certificates, counterexamples and stopping rules.
Exact assertion
Jordan algebras organize observables and positive state cones particularly well. Their strength is also their danger: many embeddings, real forms and idempotent choices are available. Without a selector, the theory can describe a landscape of possible measuring frames without choosing the one realized.
The claim supplies a map or analogy. It becomes a derivation only after an explicit carrier-preserving map and invariant are given.
Chapter “The exceptional horizon”, section “Jordan freedom and the need for selectors”. This is assertion 1 of 2 in that section.
Treat the passage as organization or analogy unless a cited carrier-preserving map is supplied.
checks assumptions, certificates, counterexamples and stopping rules.
Provide an explicit map that preserves the claimed structure, then identify an observable consequence that the analogy alone did not supply.
