Lane–Seifert Pantheon+ Baseline Qualifier — Package 1 Terminal Result: STOP

This record reports the terminal result of Package 1 of the Lane–Seifert Pantheon+ Baseline Qualifier. Under the preregistered TA-01/TA-03 qualification procedure, the baseline qualifier reached a valid terminal scientific STOP at gate H_P1690_z004. The three-seed importance-nest...

A Licensing Audit of General Relativity in Late-Time Cosmological Channels

Cosmological tests of general relativity are often summarized at the level of a probe or a data set: a result is said to be consistent with GR, to constrain modified gravity, or to disfavor a named alternative. This paper asks a narrower evidential question: what, exactly, do sel...

From Fit to Attribution: What the Bullet Cluster and DESI DR2 Support

Strong cosmological evidence can support a model package without yet fixing what physical claim inside it is licensed. We ask a narrower question: where, in a published inferential pipeline, does the force of a component attribution enter, and where does it stop? We develop a con...

Structural Preconditions of Physical Description: A Functional Account of Applicability Conditions

Physical theories operate only if their claims can be about determinate targets, range beyond isolated tokens, impose non-trivial rule-governed structure on assignments, relations, transitions, or their weights, and—where change is described—distinguish ordered configurations. Th...

Preregistration: Pantheon+ Lane–Seifert Likelihood-Architecture Switch

Preregistration of a controlled likelihood-architecture switch analysis for Pantheon+ supernova cosmology. The primary objective is to determine how much the Bayes factor between timescape and spatially flat ΛCDM changes when the hierarchical Lane latent-variable architecture is...

When Physical Applicability Fails: A Token-Level Verdict Protocol for Physical Claims

A physical claim can be mathematically well formed, empirically non-trivial, and still leave open whether its asserted physical content is licensed by the commitments that carry it. This paper supplies the token-level verdict layer for an applicability framework developed in two...

Ruling Out Entirely? Modal Compression and Selective Scope Rendering in the Galactic Centre Excess Debate

On 5 December 2016, a preprint on the Galactic Centre gamma-ray excess announced at its citable surface that the point-like nature of the emission rules out the dark-matter interpretation of the excess ‘entirely’. We examine the relation between that surface and the argument bene...
