BB-FPM-2B: S-Brane Microscopic-Closure Audit

This project tests whether acquired S-brane and gauge-production models close the tension, junction normalization, produced stress tensor, and subsequent Kantowski–Sachs child evolution required by FPM-2A.

Result

FPM2B-B_conditional — predictive closure fails; an imported radiation realization recollapses or freezes.

• The action-normalized junction jump is retained at one half the printed magnitude, subject to normal orientation.
• The published tension remains a scaling estimate rather than a calculated coefficient.
• Imported isotropic and radial gauge-radiation realizations do not sustain a long-lived isotropizing child.
• The energy comparison remains a conditional microscopic bridge, not a source-derived conservation failure.
• This closes the acquired radiation realization, not every possible S-brane microphysics.

Scope

The black-hole S-brane decay channel is not independently derived by the acquired reheating source. Results are conditional on importing its radiation stress into the anisotropic child geometry.
