All computations are in one script, run_all.py, Python 3 with numpy only. Every model is written
from the standard formula and cited in-table by name rather than by reference. Randomised procedures are seeded
(default_rng(20261103)). Numbers in the pages are read from results/all_results.json;
none is typed by hand.
Computations performed:
If one sentence survives this batch: a model with a free coefficient will usually produce the effect you are looking for, and the count of free coefficients is the cheapest available estimate of how much of the result is the model rather than the world.
Part B · new hypotheses from the existing record
The hub currently carries, among others: I2 (a substrate-conductance bias in in-plane thermal conductivity, with a corrected crossover at λ = 0.4348); H0199 (reference-witness placement, with a 23% edge bias that is flat in N); N0751 (a differential swelling sensor with a matched-time control); H034 (elastic dipoles and MLIP error); H0346 (a hydrogel negative result); #13 (magnetic battery warning); #15 (sodium pulse charging); #24 (tactile calibration); and the storage-chronology analysis.
Two structural themes recur across them, and both are testable without a laboratory:
The new hypotheses below are derived from those two themes rather than from new physics.
Claim. For any measurement where a reference is subtracted, the spread of the reported quantity across accepted reference choices is predictable from the number of unmeasured reference parameters.
Test run. Pipe friction across flow regimes, where "regime" is the unmeasured reference parameter: spread 31.6× across regimes, 1.00× within a specified regime, 1.26× between two accepted turbulent correlations. The spread collapses exactly when the missing parameter is specified.
Disposition. test now — apply to I2's four literature cases and to H0199's six layouts. Both already have the numbers; this is a re-scoring, not a new experiment.
Claim. The probability that a proposed sensor appears to work rises with the number of free coefficients in its model, and the rise is steep enough to explain a substantial fraction of published sensor demonstrations.
Test run. A three-channel selectivity model at four levels of freedom: 0% of draws show an apparent reversal at one or two free coefficients, 13.2% at three, 24.0% at four.
Disposition. test now for N0751 — its 6.5% gain-matching requirement is precisely a free-coefficient count. The question is whether the published performance survives when the gain is fixed at the measured value.
Claim. A model with no saturating channel cannot produce a selectivity crossing; a reversal reported without one is a parameter artefact.
Test run. 600 random channel sets: 0 violations. Stress test with 0–4 forced saturating channels: maximum crossings observed 2 in every case, including S = 4, where a bound of S − 1 = 3 would have allowed more.
Disposition. test now as a screening rule; the tighter bound of 2 is unexplained and is itself a question (see N-11).
These are reported because they contradict what I expected, and one contradicts a claim made earlier in this batch.
I expected that a power-law exponent fitted over a narrow window would be poorly determined, supporting the view that fitted exponents are not measurements. The opposite happened. Recovering a known exponent n = 3 from data with 2% noise: over half a decade the fitted exponent has mean 3.00 and standard deviation 0.015; over three decades, 0.003. The exponent is recovered well even in the narrow case.
Consequence: my claim is withdrawn. The "fitted exponent is meaningless" argument does not survive at this noise level. It may survive at higher noise or with a systematic curvature, but I have not shown that, and the honest statement is that the test refuted my expectation.
I expected the reversal base rate to rise with the width of the parameter range. It did not: over 1, 2 and 4 decades the rate was 22.0%, 23.0% and 13.0% — non-monotone, and lower for the widest range.
Interpretation, cautiously. With a very wide range the parameters are more often far apart, which places the crossing outside the observation window rather than inside it. That is a plausible mechanism, but it is post hoc. The pre-registered expectation was wrong and is recorded as such.
| # | Hypothesis | Derived from | Disposition |
|---|---|---|---|
| N-04 | The I2 crossover λ* = 0.4348 is a universal constant of the Gaussian-spot geometry, and should be recoverable from any heat-spreading measurement regardless of material. | I2 | test now — reanalyse any published spot-size series |
| N-05 | H0199's 23% edge bias, being flat in N, is a boundary-value property rather than a sampling property; it should therefore appear identically in any smoother with a boundary condition at the domain edge. | H0199 | test now — swap the smoother; the bias should be invariant |
| N-06 | N0751's matched-time control is more diagnostic than its thickness fit, because a common-mode gain error cancels in the control but not in the fit. | N0751 | note — needs the device |
| N-07 | A two-parameter collapse (R, ζ) is minimal for second-order tracking; no one-parameter version exists for order ≥ 2. | batch 1 | note — small maths problem |
| N-08 | Any "intrinsic activity per area" figure is circular in the specific capacitance used to compute the area, so the circularity is diagnosable from the reported number alone. | hub Q010 | test now — check 20 papers for the assumed constant |
| N-09 | Catalytic rate constants normalised by total protein concentration will show a systematic offset equal to the unmeasured active fraction, and the offset should correlate with purification method. | hub Q016 | note — needs data |
| N-10 | The magnetic battery-warning signal is set by the return geometry, so a wire phantom can establish signal-to-background but cannot establish warning time; the two claims must be separated in any test. | #13 | note — apparatus |
| N-11 | The observed bound of two crossings, independent of the number of saturating channels, suggests the sign of N − D is determined by its two largest terms; a proof would give a much tighter screening rule than S − 1. | batch 1 T3 | test now — mathematics, no apparatus |
| N-12 | For a parallel-channel membrane, a reversal requires the two gases to be ranked oppositely by at least two channels; this is a necessary condition that can be checked without any simulation. | batch 1 | test now — check against reported reversals |
| N-13 | The spread at fixed dimensionless number predicts out-of-sample failure of a law, with a correlation too weak to be a screening tool on its own (measured 0.535). | batch 1 T6 | closed as a screen — too weak |
| N-14 | Handbooks constants that no one has re-measured will show a systematic bias toward round numbers, which is diagnostic of a copied rather than measured value. | hub U017 | test now — digit analysis on a handbook |
| N-15 | Storage-chronology results depend on the persistence control chosen, so any storage comparison that does not state its control is not comparable to another that used a different one. | storage record | note — editorial, not computational |
If one thing survives: of fifteen new hypotheses, three were cheap enough to test immediately, two of the three tests contradicted what I expected, and the hypotheses that survived are the ones that produced a number rather than an argument.
Part C · batch 2: estimator dependence, parity for Hill channels, eight more audits
Page 3 reported that H203's tail index (α ≈ 1.33–1.41) does not reproduce, getting α ≈ 0.26–0.62 by Hill. That left open whether the data or the estimator was at fault. Two estimators on the same 602-event catalogue settle it.
| Threshold (kt) | Exceedances | Hill α | PWM α | Hill drift |
|---|---|---|---|---|
| 1.0 | 602 | 0.440 | 0.325 | — |
| 2.0 | 590 | 0.619 | 0.325 | +41% |
| 5.0 | 369 | 0.722 | 0.323 | +64% |
| 10.0 | 237 | 0.781 | 0.321 | +78% |
| 20.0 | 133 | 0.745 | 0.318 | +69% |
The two estimators disagree by a factor of 1.4–2.4, and they behave differently. Hill drifts upward by 78% as the threshold rises — the classic signature of applying it outside its valid region, or of a catalogue whose completeness changes with energy. The probability-weighted moment estimator is stable to three digits (0.318–0.325) across a 20× threshold range.
Conclusion. The tail index of this catalogue is 0.32, not 1.35, and the number is estimator-dependent by a factor of two. H203's reported value cannot be reproduced with either estimator, which means the value should not be quoted until the estimator and the catalogue snapshot are both specified. This is a resolution, not a further failure: the discrepancy is now attributable to method rather than to data.
Transferable rule: a tail index reported without its estimator and its threshold-stability check carries an uncertainty of at least a factor of two, which is larger than the difference between the physical models such indices are used to distinguish.
Page 2 proved that the number of crossings has the parity of α at P→0 and P→∞, and verified it for Langmuir channels (S = 1). Two follow-ups:
600 trials with p ∈ {0.5, 2, 4}: 0 parity violations. The theorem does not depend on the functional form of the saturating term — only on monotonicity and finite limits, which every Hill term has for p > 0.
| Stratum | 0 | 1 | 2 | 3 | 3+ count |
|---|---|---|---|---|---|
| Equal counts | 1065 | 355 | 79 | 1 | 1 |
| Unequal counts | 1205 | 258 | 35 | 2 | 2 |
Hypothesis N-24 claimed three crossings require unequal channel counts. It is refuted: one three-crossing case occurred with equal counts. The rate is higher with unequal counts (2/1,500 versus 1/1,500) but the exclusion does not hold.
| Quantity | Group | Compared at | Spread | The missing parameter |
|---|---|---|---|---|
| Compressibility correction | Mach | M = 0.7 | 1.39× | order of the expansion |
| Wave resistance | Froude | Fr = 1 | 2.00× | hull form and wave regime |
| Droplet breakup threshold | Weber | critical | 1.40× | residence time, viscosity ratio |
| Mass-transfer coefficient | Péclet | Pe = 100 | 1.06× | flow geometry |
| Lumped-capacitance error | Biot | Bi = 0.1 | 1.03× | internal gradient, by definition |
| Drag-crisis onset | Reynolds | transition | 2.00× | free-stream turbulence |
| Forced-convection Nusselt | Reynolds | Re = 10⁴ | 1.18× | entry-length correction |
| Heat–mass analogy | j-factor | matched j | 1.25× | Prandtl–Schmidt difference |
These eight span 1.03× to 2.00×. The first eight spanned 0.09× to 125.9×.
That gap is not a property of physics. It is a property of how I chose the first eight — I picked pairs where the disagreement was known to be large, and reported the median as if it were representative. The honest combined statement is that the spread across sixteen laws ranges from 1.03× to 126×, with the upper end over-represented by selection.
This is the second time in this batch that a claim of mine has failed under its own test. The pattern: the dramatic cases get noticed and the boring ones do not, and a criterion built only from the dramatic cases will overstate itself.
Each branch takes an existing result and pushes it to a question that did not exist before this batch.
From §1: if a tail index moves by 2× between estimators, every discipline that quotes one has a hidden systematic at least that large. Tests: (A-i) recompute twenty published tail indices with three estimators; (A-ii) test whether the estimator choice correlates with the claim being made; (A-iii) build a "minimum-reporting" template and apply it to one field.
From §2: any ratio of monotone bounded sums obeys the parity constraint. Tests: (B-i) restate the proof for the general class; (B-ii) apply it to twenty published thermal and ionic rectification claims; (B-iii) determine the maximum crossing count for 6 channels per side.
From §3: my criterion overstates itself because the calibrating cases were chosen for drama. Tests: (C-i) recalibrate the spread criterion on a random sample rather than a curated one; (C-ii) test whether published review articles show the same bias; (C-iii) propose a sampling rule for calibrating any new screening criterion.
From page 3: I2's 75.8× spread is a reference effect. Tests: (D-i) compute the equivalent reference ratio for three other methods; (D-ii) test whether reporting the ratio removes the cross-study spread; (D-iii) find the methods where it cannot be removed.
From page 3: one live catalogue was re-analysed and half the claims changed. Tests: (E-i) queue five more public catalogues; (E-ii) automate the "derived-column" check (is one column a function of another?); (E-iii) publish a replication template.

If one sentence survives batch 2: the same catalogue gives a tail index of 0.32 or 0.78 depending on the estimator, which is a larger difference than the physical effects such indices are used to argue about — and my own spread criterion overstated itself because I picked its test cases.
Part D · from screens to designs: two-switch membranes and three reporting standards
The parity theorem says a crossing count is even when α(0) and α(∞) agree, odd when they differ. That rules out "at most two" and permits exactly two — a selectivity that switches off and back on as pressure rises. Whether such a design exists is a separate question from whether it is permitted. It exists.
A parameter search over three channels per side (equal counts) found three designs with two crossings, all with same-side limits as the theorem requires.
| Side | channel 1 | channel 2 | channel 3 |
|---|---|---|---|
| N | K=0.117, A=8.07, b=99.6 | K=1.276, A=1.40, b=5.95 | K=0.104, A=0.46, b=0.98 |
| D | K=0.414, A=4.31, b=0.33 | K=0.149, A=3.52, b=46.1 | K=2.087, A=4.10, b=89.3 |
α(0) = 0.584, α(∞) = 0.784, peak 1.006. Crossings at 0.0156 bar and 0.431 bar. The selectivity starts below 1, rises just above it, and returns — a two-state window roughly two decades wide.
α(0) = 0.846, α(∞) = 0.797, peak 2.001. Crossings at 0.00237 bar and 2.80 bar. This is the strongest of the three: a three-decade window in which the preferred gas reverses, with the ratio doubling at the peak.
α(0) = 0.250, α(∞) = 0.644, peak 1.032. Crossings at 0.142 bar and 0.782 bar.
This is the batch's first constructible output. The parameters are a blueprint for a membrane whose selectivity reverses twice. Whether any real material realises these Langmuir constants is a separate, material-specific question — but the target is now a number, not a hope.
The fireball tail index came out 0.32 (PWM) or 0.78 (Hill) on the same data, a factor 2.4. Any field quoting a tail index has at least this spread hidden. The design is a reporting standard:
| Required item | Why |
|---|---|
| Three estimators (Hill, MLE, PWM) | their spread is the methodological uncertainty |
| Threshold-stability plot | a drifting estimate signals an incomplete catalogue |
| Catalogue snapshot (n, date) | catalogues change; the index does not |
| Derived-column flag | a derived column makes the index non-independent |
Design rule: if the three estimators disagree by more than the effect being claimed, the index cannot support the claim. On CNEOS that threshold is a factor 2.4.
I2's four literature cases span 75.8× in reported conductivity purely through λ. The design is the same shape as branch A's:
A constructive inversion: a substrate-dominated measurement (λ ≫ 1) is a poor κ measurement but an excellent substrate measurement. Methods that fail at their intended quantity can be repurposed at the quantity they actually measure.
The CNEOS catalogue contains two columns correlated at 0.99992 in log–log with a residual of 0.0064 dex. That is not two measurements; it is one measurement and a recalibration. The detector:
if log-log R² > 0.999 and residual sd < 0.02 dex:
flag the pair as derived, not independent
Applying it to any catalogue takes seconds and prevents an entire class of double-counting errors. The rule generalises: before using two columns as independent evidence, check whether one is a function of the other.

| A1.7 | A tail index and its estimator spread should be reported as a pair, like value and uncertainty. | note |
| A1.8 | Derived columns are common enough that a repository audit would find several. | test |
| A1.9 | Threshold-stability curves could be a required figure in any tail-fitting paper. | note |
| A1.10 | The 0.32 value is a defensible reference for CNEOS and can be quoted with its stability. | test |
| A1.11 | Estimator dependence is worst where the data are most truncated. | test |
| A1.12 | A standard would make half of tail-based claims unpublishable as stated. | note |

| D1.1 | λ should be a reported quantity, like an uncertainty. | note |
| D1.2 | A two-spot protocol with one spot below λ = 1 is the minimum viable measurement. | test |
| D1.3 | Substrate-dominated measurements can be repurposed as substrate measurements. | test |
| D1.4 | The 75.8× spread is computable from reported spot sizes alone, so any reader can check it. | test |
| D1.5 | Three of four published 2D conductivities are substrate-limited. | test |
| D1.6 | The same λ structure exists for any measurement with a substrate term. | test |
| D1.7 | A reference ratio can be designed into a device to make it reference-insensitive. | note |
| D1.8 | Reference-dominated methods should report their reference, not their sample. | note |
| D1.9 | The two-spot rule generalises to two-condition protocols in other fields. | test |
| D1.10 | Inter-laboratory disagreement would halve on re-expression in one convention. | test |
| D1.11 | A reference-free measurement exists wherever the reference enters linearly. | test |
| D1.12 | Reporting the mechanism of failure (λ > 10) is more useful than reporting the number. | note |

| E1.1 | Half of publicly checkable claims change status on re-analysis; test on five more. | test |
| E1.2 | Derived-column detection automates the first check. | test |
| E1.3 | Snapshot dates should be mandatory for catalogue-based results. | note |
| E1.4 | Conditional claims survive re-analysis better than unconditional ones. | test |
| E1.5 | A five-catalogue audit would establish the base rate. | test |
| E1.6 | Replication takes an hour per claim once the data are public. | test |
| E1.7 | Most catalogues have at least one derived column; find them. | test |
| E1.8 | Re-analysis should be citable, and is not. | note |
| E1.9 | The residual of a derived relation recovers the hidden variable. | test |
| E1.10 | Public APIs are under-used relative to their accessibility. | note |
| E1.11 | Volume incompleteness is detectable from tail drift alone. | test |
| E1.12 | A replication template halves the time to a verdict. | note |
| Rank | Lead | Why | Cost |
|---|---|---|---|
| 1 | B1.2 / B1.9 | A new device class with a mapped design cube. First constructible output of the batch. | days, simulation |
| 2 | A1.1 | Three-estimator audit of twenty published indices could move a field. | days, no lab |
| 3 | D1.5 | If true, a large literature is measuring substrates. | hours, reanalysis |
| 4 | E1.5 | Establishes the replication base rate across five catalogues. | days, APIs |
| 5 | B1.4 | Three-switch design: tests the parity limit at its edge. | hours, simulation |
If one sentence survives: the parity constraint turned a screen into a design rule, and the rule produced three two-switch membranes with full parameters — the first thing in this batch that could be built rather than checked.
