braneworld

5D Gauss-Bonnet braneworld solution with holographic transfer function. First-principles derivation complete; observational test shows S₈/Lyman-α incompatibility. Falsification analysis published.

Direct literal-interval scalar second variation: healthy vacuum sector with sourced brane-bending closure still incomplete.

Action-normalized causal scalar response whose conformal lensing cancellation makes it unsuitable for the proposed halo role.

Warped tensor spectrum and cross-interface response: healthy tower, but no useful halo-like radial interval.

Convention-fixed literal-interval repair that closes the warped action at first variation and on the exact background.

Normalization and physical-scale dependency audit showing an empty galactic response domain for the frozen GP-2R benchmark.

Finite-bulk gravity-response audit deriving a healthy tensor kernel while recording scalar, lensing, and EFT closure failures.

Scalar-stabilization audit showing the minimal canonical completion is incompatible with the exact flat GP-1 background.

Backreacted warped scalar-gravity audit: the exact background closes while the coupled scalar and lensing response remains incomplete.

First-variation boundary audit showing that the written GP-2 interval action fails literal boundary closure.

Coupled scalar-spectrum audit proving positive norm and mass while rejecting the conformal scalar as a standalone lensing signal.

Induced-gravity scalar Hessian and rank archive preserving TEST 024 plus the unexecuted TEST 027 health-grid implementation.
