33-facet audit registry
May 2026 headline bins: 20 PASS / 13 NEUTRAL / 0 FAIL after the homogeneous BAO null-geometry revision. This is not a generic “GR unit test” list: every row names a null baseline (\(\Lambda\)CDM structure, Einstein GR, Standard Model electroweak/QCD/BBN, or a spelled combination) and states how the DCT closure differs from that baseline. Machine source: facet_registry.json (validated by validate_facet_registry.py). Framing: audit_fails.py.
Columns Null baseline and DCT contrast are the discriminant: they record what \(\Lambda\)CDM / GR / SM would assert in isolation and what is distinctive about the DCT prediction, falsification mode, or inherited sector. Remaining columns link the derivation (cluster paper), per-observable detail where it exists, and /files/code/ verification scripts (plus empirical T-harness run.py when wired).
| ID | Facet | Verdict | Null baseline | DCT contrast | Paper | Observable | Scripts | Notes |
|---|---|---|---|---|---|---|---|---|
PASS-01 | Homogeneous background BAO / radial null χ(z) | PASS | ΛCDM + Einstein GR (homogeneous BAO / χ(z) with matched H(z)) | Retracted audit map inserted a uniform comoving D_M ∝ 1/√P₀ factor; homogeneous P(t) cancels from radial null geodesics. That is not an extra fitted degree of freedom in baseline ΛCDM and is geometrically distinct from standard ruler fitting. | DCT-BAO-01 | /observables/bao/ | exploratory/bao_conformal_null_check.py · dct_desi_bao_test.py | P(t) cancels in radial photon nulls; comoving χ(z) unchanged versus matched expansion history. |
PASS-02 | Hulse–Taylor binary pulsar orbital decay | PASS | Einstein GR (quadrupole radiation damping) | Radiation sector uses Brans–Dicke ω fixed by the master identity (ω₀=50,037 from P₀, c_BD); not a two-parameter scalar–tensor fit with free ω. | DCT-SBD-01 | /observables/hulse-taylor/ | gravity_tests.py | — |
PASS-03 | Double pulsar PSR J0737–3039 (orbital + PK parameters) | PASS | Einstein GR (binary pulsar PK + orbital timing) | Full J0737 suite tied to the same locked-ω Brans–Dicke sector as PASS-02; distinguishes DCT from unconstrained modified-gravity templates. | DCT-SBD-01 | /observables/double-pulsar-7pk/ | gravity_tests.py | Single facet bin for the J0737 system (orbit + post-Keplerian suite). |
PASS-04 | MICROSCOPE equivalence principle (η) | PASS | Einstein GR (exact Nordtvedt η=0 in pure GR) | Finite Nordtvedt parameter at the PPN values implied by (γ,β) locked to ω₀; EP observables are not the exact GR null once the scalar tie is fixed. | DCT-PPN-01 | /observables/microscope-eta-ep/ | gravity_tests.py | — |
PASS-05 | GW170817 gravitational-wave speed | PASS | Einstein GR (tensor graviton, c_GW=c) | Metric subclass forces luminal tensors; excludes coherence-field modified dispersion that would split from baseline GR at GW170817 precision. | DCT-SBD-01 | /observables/gw170817-cgw/ | gravity_tests.py | — |
PASS-06 | GWTC-3 BBH population / ringdown no-hair consistency | PASS | Einstein GR (Kerr no-hair, QNM ringdown) | No-scalar-hair inheritance with ω locked; LF constraints differ from generic Brans–Dicke where a light scalar can regenerate hair. | DCT-SBD-01 | /observables/bh-no-hair/ | gravity_tests.py · ligo_gravitational_wave_analysis.py | — |
PASS-07 | GW170817 neutron-star tidal deformability | PASS | Einstein GR (tidal Love numbers) | Tidal deformability stays on the GR+EOS band tested by GW170817; constrains scalar channels that would materially move Λ at fixed masses. | DCT-SBD-01 | /observables/gw170817-tidal/ | gravity_tests.py | — |
PASS-08 | Lunar laser ranging — Nordtvedt η | PASS | Einstein GR (η≡0) | Same finite-η PPN target as MICROSCOPE row but LLR-specific cadence; still fixed by (γ,β) from ω₀, not fit independently. | DCT-PPN-01 | /observables/nordtvedt-eta/ | gravity_tests.py | — |
PASS-09 | Lunar laser ranging — Ī/G | PASS | Einstein GR (Ī/G=0) | Brans–Dicke time evolution of G at amplitude set by locked constants, not a phenomenological Ī/G sweep. | DCT-PPN-01 | /observables/llr-gamma/ | gravity_tests.py | — |
PASS-10 | Vessot GP-A gravitational redshift | PASS | Einstein GR (gravitational redshift in Schwarzschild) | Classical redshift test with matter on the physical conformal metric; same null geodesics as GR for this observable class. | DCT-PPN-01 | /observables/gp-a-redshift/ | gravity_tests.py | — |
PASS-11 | Pound–Rebka redshift | PASS | Einstein GR (gravitational redshift) | Laboratory redshift check as for GP-A; ontology matter on Pg̃ versus bare GR, not an added fitted potential parameter. | DCT-PPN-01 | /observables/pound-rebka/ | gravity_tests.py | — |
PASS-12 | Atom interferometry (Newtonian acceleration) | PASS | Newtonian labs + Einstein GR weak field | Atom interferometry tracks SPI-sector prediction with polytope-locked inputs; distinct from ad hoc fifth-force additions. | DCT-SPI-01 | /observables/atom-interferometry-g/ | gravity_tests.py | — |
PASS-13 | GP-B geodetic precession | PASS | Einstein GR (Lense–Thirring / geodetic precession) | Frame-dragging and geodetic magnitudes from PPN (γ,β) tied to ω₀; not an independent free PPN fit per experiment. | DCT-PPN-01 | /observables/gp-b-geodetic/ | gravity_tests.py | — |
PASS-14 | Inner-planet perihelion precession (PPN suite) | PASS | Einstein GR (Shapiro + planetary perihelion) | Inner-planet precession bounded by the same locked PPN stack as Cassini-class tests. | DCT-PPN-01 | /observables/perihelion-precession/ | gravity_tests.py | — |
PASS-15 | CMB low-ℓ quadrupole amplitude | PASS | ΛCDM Gaussian CMB template (large-scale ℓ) | Low-ℓ quadrupole handled by the coherence-sector mechanism in DCT-CMB-01 rather than as a stand-alone stochastic draw with no structural link to P₀. | DCT-CMB-01 | /observables/cmb-low-quadrupole/ | cmb_analysis.py | — |
PASS-16 | Bullet Cluster lensing–baryon offset | PASS | ΛCDM + collisionless dark matter interpretation | Gas–lensing offset explained without particle DM via tie-field gradients + Yukawa interface; not the same microphysics as baseline ΛCDM halos. | DCT-DM-01 | /observables/bullet-cluster/ | astrophysical_tests.py | — |
PASS-17 | Gauge-sector conformal invariance at recombination (wall theorem) | PASS | Standard Model gauge sector + FLRW Einstein frame | Four-dimensional conformal-wall theorem pins dimensionless SM/CMB ratios at recombination; differs from treating Jordan→Einstein as arbitrary rescaling of fitted SM parameters. | DCT-CMB-01 | /observables/conformal-wall-theorem/ | cmb_analysis.py | Dimensionless CMB observables at last scattering inherit SM structure; checked via conformal-wall pipeline. |
PASS-18 | Muon g−2 (Fermilab E989 closure) | PASS | Standard Model (data-driven a_μ prediction gap) | Additive tie-field contribution fixed by (P₀,c_BD) closes the E989 gap without a dedicated new parameter tuned only to a_μ. | DCT-SM-01 | /observables/muon-g-2/ | muon_g_minus_2_analysis.py | — |
PASS-19 | Neutron-star maximum mass (J0740+6620, Shapiro delay) | PASS | Einstein GR + nucleonic EOS (NICER / mass–radius) | TOV band and Shapiro mass inherited through no-hair; falsifies branches that shift M_max while contradicting the locked weak-field PPN sector. | DCT-SBD-01 | /observables/ns-mmax-j0740/ | astrophysical_tests.py | Strong-field TOV sector; DCT inherits GR + nuclear EOS band. |
NEUT-01 | W boson mass | NEUTRAL | Standard Model electroweak fits (PDG) | W mass tracks the same SM-facing tension catalogued in PDG-era fits; not a separate DCT-only high-σ discriminator in this bin. | DCT-SM-01 | /observables/w-boson-mass/ | particle_physics_tests.py · T_PARTICLE_STRUCTURE/run.py | At or below current PDG tension for strict PASS/FAIL binning. |
NEUT-02 | Fine-structure constant α (null + quasar variation) | NEUTRAL | Standard Model local α + quasar spatial-drift literature | Conformal-wall enforces local gauge coupling invariance; large-scale spatial-gradient claims remain disputed between surveys — not a clean split from baseline cosmology here. | DCT-SPI-01 | /observables/inv-alpha/ | particle_physics_tests.py · T_PARTICLE_STRUCTURE/run.py | Conformal-wall protects local α; spatial-gradient claims remain qualitatively contested in the literature. |
NEUT-03 | Higgs sector (mass / couplings) | NEUTRAL | Standard Model Higgs EFT + PDG masses | Higgs couplings ride on the structural/particle sector without a private Higgs fit orthogonal to the SM baseline at current precision. | DCT-SM-01 | /observables/higgs-yukawa-running/ | particle_physics_tests.py · T_PARTICLE_STRUCTURE/run.py | — |
NEUT-04 | BAO sound horizon r_d drag scale | NEUTRAL | ΛCDM acoustic scale r_d | Homogeneous P(t) does not shift standard r_d at the null-χ level; discrimination moves to perturbation/cluster observables (see cluster papers). | DCT-BAO-01 | /observables/sound-horizon-rd/ | dct_desi_bao_test.py | Degeneracies with standard ruler calibration; not a sharp DCT-specific discriminator at background level. |
NEUT-05 | Planetary gravity multipoles / J₂ harmonic | NEUTRAL | Einstein GR solar multipoles + planetary interior models | Solar-system β / J₂ band; any DCT shift is below the facet precision relative to GR-led ephemerides. | DCT-PPN-01 | /observables/beta-ppn/ | gravity_tests.py | Solar-system quadrupole sector; binned as neutral in the headline 33-facet split. |
NEUT-06 | BBN helium-4 mass fraction Y_p | NEUTRAL | Standard Model big-bang nucleosynthesis | Y_p prediction inherits SM BBN; failures would be shared SM issues, not an isolated DCT falsifier in this row. | DCT-COS-01 | /observables/helium4-abundance/ | cmb_analysis.py | SM BBN inheritance; not a standalone DCT discriminator. |
NEUT-07 | EHT black-hole shadow diameter (M87* / Sgr A*) | NEUTRAL | Einstein GR Kerr imaging + plasma / scattering systematics | Shadow diameter agreement within EHT systematic floors; DCT does not yet advertise a contrasting ring size at this precision. | DCT-SBD-01 | /observables/m87-polarisation/ | astrophysical_tests.py | Agreement within current ring astrophysics / scattering systematics. |
NEUT-08 | Electron g−2 | NEUTRAL | Standard Model QED (electron a_e) | Tie-field contribution suppressed by m_e/m_μ; effectively the SM QED test at reported precision. | DCT-SM-01 | /observables/electron-g-2/ | particle_physics_tests.py · T_PARTICLE_STRUCTURE/run.py | DCT shift suppressed versus muon; experiment not yet at theory discriminating power in this binning. |
NEUT-09 | Large-scale cosmic dipole / spatial gradient puzzles | NEUTRAL | Statistically isotropic ΛCDM + Copernican priors | Large-scale directional anomalies and quasar-α dipole tensions are qualitative; literature is contested, so the row does not isolate DCT numerically. | DCT-COS-01 | — | particle_physics_tests.py | Qualitative directional systematics (CMB kinematic dipole, quasar α-dipole tensions); no dedicated observable slug. |
NEUT-10 | Cold dark matter density Ω_DM h² | NEUTRAL | ΛCDM (Ω_c h² bookkeeping) | Dark-matter density tracked only at order-of-magnitude in this audit bin, not as a sharp parameter prediction unique to DCT. | DCT-DM-01 | /observables/omega-m-h2/ | cosmological_tensions_analysis.py | Order-of-magnitude consistency only in this audit bin. |
NEUT-11 | BBN lithium-7 (shared SM tension) | NEUTRAL | Standard Model BBN (Spite plateau) | Lithium problem is SM-BBN shared tension unless a dedicated DCT thermochemical correction is isolated. | DCT-COS-01 | /observables/lithium7-primordial/ | cmb_analysis.py | Inherited SM BBN problem unless a sharp DCT correction is isolated. |
NEUT-12 | Cassini PPN γ precision floor | NEUTRAL | Einstein GR (γ−1=0 exactly) | DCT predicts γ−1=−1/(ω₀+2); Cassini precision ties GR and DCT — separation awaits BepiColombo-class radio science. | DCT-PPN-01 | /observables/cassini-gamma/ | gravity_tests.py · T_PPN_GAMMA/run.py | Consistent with DCT but does not yet separate from GR at designed precision. |
NEUT-13 | Cosmic chronometers H(z) / naive uniform BEC multiplier | NEUTRAL | ΛCDM distance-calibrated H(z) | Per-z cosmic chronometers reject a naive uniform H_BEC/H_ΛCDM=1.084 narrative; the row does not by itself pick DCT over ΛCDM without shape information beyond this scalar diagnostic. | DCT-COS-01 | — | dct_eddington_ratio_per_z.py · T_CC_NEUTRAL/run.py | Per-z Moresco compilation: mean ratio compatible with ΛCDM; rules out naive 1.084 uniform factor (see T_CC_NEUTRAL). |
FAIL-01 | KiDS-Legacy 2025 S₈ cosmic shear | FAIL | ΛCDM late-universe structure (KiDS-Legacy lensing) | Constant-P₀ growth lowers S₈ versus KiDS-2025 without an extra tuned late-time parameter on that branch — a direct amplitude split from baseline ΛCDM lensing fits. | DCT-COS-01 | /observables/kids-legacy-s8/ | cosmological_tensions_analysis.py · audit_fails.py | Canonical constant-P₀ growth predicts S₈ ≈ 0.776 vs 0.815 ± 0.018 (∼2σ). |
