Applicability Diagnostics

One diagnostic architecture, and the domains in which it is applied.

The guiding question

When is a physical description licensed?

Physical theories do not apply merely because they are mathematically coherent, empirically successful elsewhere, or capable of producing predictions. Their use in a particular domain presupposes conditions that must be identified and examined.

Applicability Diagnostics investigates those conditions before interpretation or explanatory transfer. It distinguishes what must hold for a description to apply, what the theory asserts, and what an empirical result licenses.

The programme describes current questions without presenting them as completed results. Claims about findings are linked only where a stable publication, DOI, or ISBN provides an external anchor.

Programme architecture

Constitutive architecture, diagnostic protocol, domains of application

Applicability Diagnostics — programme architecture A constitutive architecture (levels of description L1 to L3 and applicability conditions A1 to A6), an operational diagnostic protocol (verdicts PASS, OPEN, LoA and recurring failure signatures S1 to S7), and eight domains in which the instrument is applied. 01 · CONSTITUTIVE ARCHITECTURE L1 Conditions of applicability what must hold for it to apply L2 Theoretical content what the theory asserts L3 Empirical application what the measurement licenses SIX APPLICABILITY CONDITIONS · L1 A1 TARGET A2 INTERFACE A3 DOMAIN A4 EMPIRICAL BASIS A5 CARRIER STRUCTURE A6 CONSTRAINTS 02 · DIAGNOSTIC PROTOCOL VERDICTS PASS SATISFIED OPEN UNDECIDED LoA OUTSIDE DOMAIN RECURRING FAILURE SIGNATURES S1 S2 S3 S4 S5 S6 S7 consolidated in a necessity argument 03 · DOMAINS OF APPLICATION Quantum interpretations applicability testing of interpretive frameworks AI discovery claims when machine-found regularities count as physics Origin strategies what an explanation of a beginning must presuppose Finality demands self-applicability of final-theory claims Standard cosmology licensing audit of the GR + ΛCDM framework Quantum foundations what no-go results establish about observation itself Evidence theory what an experimental result does and does not license History of cosmology idealisation and its domain of validity RECURRENCE ACROSS DOMAINS ESTABLISHES THE ARCHITECTURE
The recurrence of diagnostic signatures across domains supports the general architecture. Open the diagram separately.

Three levels of description

L1 asks what must hold for a description to apply at all. L2 states what the theory asserts. L3 states what an empirical result licenses. Keeping the levels apart prevents a question belonging to one level from being answered with the resources of another.

Six applicability conditions

A1 (Target) requires the target system, the observable and the mapping rule to be declared; without it no verdict can be assigned. A2 (Interface) asks whether the link between claim and data is direct or runs through intermediate models. A3 (Domain) asks whether a claim stays inside the validated regime or is extrapolated beyond it. A4 (Empirical basis) asks whether a verdict survives admissible variation of the data. A5 (Carrier structure) requires postulated entities to be supported by evidence that does not already presuppose the frame under audit. A6 (Constraints) counts the outcome-relevant modelling choices left undeclared; it demands their disclosure, not their elimination.

Three verdicts

PASS records that a condition is satisfied, OPEN that it is not settled, LoA that the claim lies outside the licensed domain. Verdicts are question-relative and diagnostically neutral: they locate where a question is currently undecidable and assert nothing about how it will be resolved. A1–A6 is an audit schema rather than a score, and not every condition is decisive in every case.

Seven failure signatures

S1–S7 record failure patterns that recur across otherwise unrelated cases. It is that recurrence, rather than any single application, which supports the general architecture — the argument the diagram traces on its right-hand edge.
