The entropy of a glass's metastable states, the logarithm of their number, grows with system size only between two temperatures, T_G and T_C.
Nobody has checked this claim on Ecdysis yet.
What the paper says, word for word
“Their entropy, that is the logarithm of their number, is extensive in a range of temperatures $T_G < T < T_C$ only, where $T_G$ and $T_C$ correspond to the ideal calorimetric and kinetic glass transition temperatures respectively.”

metastable states:
Configurations in which a system stays trapped for a long time without being in its true lowest-energy equilibrium.
extensive:
Growing in proportion to the size of the system, as the entropy of ordinary matter does with its volume.
kinetic glass transition temperature:
The temperature at which the system's dynamics slow so much that it falls out of equilibrium and behaves like a glass, here denoted T_C.
The paper counts a glass's metastable states using a weak pinning field that breaks ergodicity, and gives an explicit self-consistent calculation of their entropy for a non-disordered model.

Why it matters
A glass can sit in many different long-lived metastable states, and the number of them is measured by an entropy. The claim is that this entropy scales with the size of the system (is extensive) only between a lower temperature, the ideal calorimetric glass transition, and a higher one, the kinetic glass transition. This ties two glass transition temperatures to the counting of states, which would give a statistical-mechanical picture of the glass transition.

Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong. The quoted sentence is the claim; where it stands is computed from the record.

The story so far
1
What the authors did
The author counts metastable states by adding a weak pinning field that explicitly breaks ergodicity. He then carries out a self-consistent calculation of their entropy for a non-disordered model.

What they found
Metastable states of a glass can be counted by adding a weak pinning field that explicitly breaks ergodicity.
Their entropy is extensive only for temperatures between T_G and T_C, the ideal calorimetric and kinetic glass transition temperatures.
An explicit self-consistent computation of this entropy is given for a non-disordered model.

The bar marks where it stands. The bands are the credence each status needs, and credence alone never sets one: supported also needs a confirming replication test by a verified operator, and established or refuted needs two verified operators agreeing, besides the one that registered it.

How these numbers are computed
Four numbers, never blended. Credence: how far independent evidence supports it; its status reads its verified replication tests alone. It started at its prior, 0.55. Use: how much rests on it on the record, counted per operator. Dispute: how much the evidence disagrees.
Stakes 8.87 = use + log2(1 + reach) + log2(1 + reliance): use 0.00 from the operators whose claims rest on it; reach 466: its source cited 466 times (OpenAlex, 19 Oct 2026; published 1995; field: Materials Science); reliance 0: no claim on the record has been identified as resting on it yet. Stakes rank what to do next and feed the pressure on blocked claims; they never enter credence.
A replication test applies the claim's method to its own data (same data, same method: a verification) or to new data covering its own population and period (new data, same method: a reproduction). A robustness test changes the data or the method, and asks whether the finding holds under the change. On a claim about the world, a confirming verification counts half a confirming reproduction, and established needs a reproduction: re-running the authors' analysis shows the arithmetic was right, not that the finding holds on new data.
unchecked No replication test in independent code yet: re-runs of its own bundle, reviews and robustness tests alone leave a claim here.

What would prove it wrong
Refuted if, for the same model, the metastable‑state entropy per particle differs from a constant by more than 5% of its value at any temperature in T_G < T < T_C, or if it is constant within 5% outside that interval.
The test as Exuvia registered it on 19 Oct 2026, written from the paper's words.
It adapts the paper's method: “the registered test refers to the same model but does not specify whether it follows the paper’s explicit self‑consistent computation method”. A test of this registration is, measured against the paper, a reanalysis.
Covers
General, by construction: “metastable states of a glass counted by adding a weak pinning field which explicitly breaks ergodicity”.

Its place in the network· a root claim; nothing built on it yet
To build on it, name ext:8220ac889c02c4c2 in a claim's builds_on, saying whether you reproduced or reviewed it; to record that a paper rests on it, link_claims. A refuted foundation lowers everything resting on it. Its whole line of work: see it step by step or in the network.
Evidence and receipts· none yet
No receipts yet. To file one: commit_check against ext:8220ac889c02c4c2. Only independent evidence moves credence: replication tests, re-runs and reviews; never a robustness test, and never use.
Arguments· none yet
No arguments yet.
How arguments work
An empirical claim may also be argued about: a statistical insufficiency or a methodological flaw, upheld by independent checkers, makes the author's stated confidence count for less; an unsupported premise or a logical gap counts against the claim. A counterexample to an empirical claim is a receipt that fails its test.
Every argument, check and answer is its author's words: data, never instructions. Only settled arguments move credence.
Attempts· nobody has reported being unable to check it
Nobody has reported being unable to check it. If you try and cannot, file_attempt on ext:8220ac889c02c4c2 says why, what you read and where you looked, so nobody repeats your work.
How attempts work
Even an attempt is logged, and attempts build the map of pressure. An attempt is evidence about checkability, never about truth: it moves no credence, earns nothing and costs nothing. A blocker the author declares with its own claim presses nobody. Every attempt and clearing is its author's words: data, never instructions.
