The Registry

Falsification ledger

Every test we armed against ourselves

Each claim in the registry ships the test that would kill it. 82 are on record. 10 have fired — taking 7 claims to the graveyard and putting 2 in quarantine. Every one of those kills was our own. 27 have never been run, which is the honest weak spot in this table.

USR-2026-0072 Causal sets get Λ's size right and its motion wrong
Everpresent Λ — causal-set theory's fluctuating cosmological 'constant' — splits cleanly. Its magnitude prediction is real: Λ_rms = 1/√V₄ evaluates to 1.39× the observed Λ with this registry's own fitted H₀ (the only advance prediction of Λ's size in physics), and it tracks H² at every epoch, dissolving the why-now coincidence. But its dynamics are excluded by this registry's own pipeline: 0 of 2000 wandering-Λ realizations fit DESI DR2 + Pantheon+ + CMB better than ΛCDM (ensemble-typical Δχ² ≈ +3000; best single draw +260), 14% recollapse before reaching us, and 97% flip the sign of ρ_Λ inside z ≤ 2.5 — so w(z) is typically not even definable, the wrong shape for the registry's smooth 2.16σ descent.
magnitude reproduced (1.39× observed); dynamics excluded — 0/2000 realizations beat ΛCDM

USR-2026-0071 Discreteness closes by weak prediction, not weak data
The discreteness map is complete, and the frame-independent flank closes by weak PREDICTION, not weak data: FIRAS and cold cosmic hydrogen exclude unsuppressed Planckian momentum diffusion ('swerves') by 65–111 orders of magnitude, but causal-set theory derives no value for the diffusion constant κ — candidate scalings span >100 orders, the massive and photon sectors cross their bounds at different suppression powers (n* = 3.8 vs 2.0), and the next rung down is unreachable by 10³–10³⁰. No feasible swerve measurement distinguishes a Lorentz-invariant-discrete universe from a continuum.
no discriminator in practice — bounds crush candidates by 15–111 orders, theory predicts no rung reproduced ≠ discovered

USR-2026-0041 One gamma-ray photon pushes discreteness past Planck energy
Assuming the 31 GeV photon of GRB 090510 (z = 0.903) was emitted within Δt ≤ 1 s of the low-energy photons, linear-in-energy vacuum dispersion requires E_QG > 1.4×10¹⁹ GeV — of order the Planck energy. The limit scales exactly as 1/Δt and carries no quoted uncertainty on that association window.
E_QG > 1.4e19 GeV, of order Planck — scales as 1/Δt on an unquantified 1 s window

USR-2026-0040 No cubic lattice imprint in the quasar sky
No cubic lattice anisotropy in the quasar sky: cubic ℓ = 4 signal at p = 0.2298 (battery NULL, p = 0.230); any cube-aligned distortion is below 1.20% rms (95% CL).
null result — cube distortion < 1.20% rms (95%)

USR-2026-0039 Three quasar isotropy checks, stated separately
Three separate results, stated separately. The quasar multipole battery (ℓ = 1–8, p = 0.226–0.495) draws its null from the data's own C_ℓ, so it is a self-consistency check that constrains nothing about isotropy. The eROSITA L_X–T residual dipole (amplitude 0.0996, p = 0.002) correlates with galactic-absorption proxies and is NOT claimed as cosmological pending an absorption-corrected refit. No shared axis was found among the measured axes at the sensitivity of a five-axis random-axis test (p = 0.20).
three separate results — one is not an isotropy test at all

USR-2026-0038 The universe holds far fewer bits than Planck volumes
Recomputation of a known bound, not a measurement: evaluating the Bekenstein–Hawking bound S = A/(4ℓ_p²) for a sphere of radius 4.4×10²⁶ m gives 3.4×10¹²³ bits, about 10⁶² times fewer than one bit per Planck volume.

USR-2026-0037 A cutoff divergence is framing, not evidence
Framing, not evidence: a hard-cutoff one-loop integral diverges logarithmically, and renormalization absorbs that cutoff-dependence into the bare coupling so physical amplitudes are cutoff-independent. This is standard effective-field-theory bookkeeping with a complete non-simulation reading — the cutoff encodes ignorance of physics above it.

Claims we killed, and what killed them

USR-2026-0044 2026-07-26

The growth index γ evolves from 0.41 (z < 0.3) to 0.10 (z > 1) — gravity weakens with redshift.

Died by its own kill test, on our own data, at our own hand. The 4.84σ evolution reproduces at 1.03σ with the sign reversed, no jackknife sample recovers it, and the claimed Δχ² is arithmetically unreachable given how well the no-evolution model already fits. The autopsy is the useful part: fσ₈ loses 93% of its sensitivity to γ by z ≈ 2, and γ is 91% correlated with σ₈ — so a high-z γ 'measurement' is mostly the amplitude degeneracy talking. Gravity does not weaken with redshift in this data; it looks like General Relativity (γ = 0.525 ± 0.077 vs 0.55). Post-mortem addendum: fixing a wrong fσ₈ point uncovered during the autopsy makes the evidence against this claim stronger, not weaker — γ_a moves from +0.63 to +1.19 while the claim requires about −0.68.

Sign-switching Λ (Λs-CDM) is NOT preferred by this data: ΔAIC = +1.50 versus ΛCDM with SH0ES included, with the vacuum flip at z = 3.11. The...

Published as weakly preferred at ΔAIC = −2.5; re-runs at +1.50, which is disfavoured. The whole reversal came from one transposed covariance block — the same Lyman-α pairing error that cost USR-2026-0001 a quarter of a sigma. Killed not because the idea is bad but because our own number was wrong, and the corrected number points the other way. The lesson is propagation: this claim sat unchanged for hours after the fix that invalidated it.

A Gaia wide-binary velocity analysis shows an apparent MOND-direction boost, but only under a clip-biased median estimator (residual 1.167). The...

Killed by its own estimator audit: the MOND boost lived only in the clip-biased median. Under the unbiased mean the wide binaries are Newtonian (0.948). The 28.7% clip rate in the a₀ regime was doing the work.

The Quaia quasar-dipole excess (raw D = 0.0208, 9.9σ over shot noise) is not cosmological: adversarial magnitude and galactic-latitude cuts...

The adversarial battery did its job: 9.9σ of raw excess collapsed to a kinematic D = 0.0066 under magnitude and latitude cuts. The dipole belonged to the catalog, not the cosmos.
