PAPER-FBT01C: A Conjectural Gravitational Reading of Dual-Phase Flux

The companion paper FBT01A revises the curvature-readout structure of the Fracture–Berry–Tension (FBT) carrier geometry. In the current formulation, the relevant scalar data are no longer organized as a rigid three-κ system. Instead, one distinguishes the global Liouville capacity of the six-dimensional carrier, Kvol =󰁝B61/3!Ω∧3B , the normalized reduced dual-phase flux Kphase =1/2π󰁝Σ2Ωeffphase, and the local horizontal–vertical mixed legibility density ρmix. The present paper proposes a restricted conjectural physical reading of these quantities, focused only on effective gravitational coupling. The central claim is conjectural rather than derived. The reduced dual-phase flux Kphase is argued to be the most natural candidate for controlling the dimensionless geometric factor ggrav in an effective four-imensional gravitational coupling. The argument is structural: Kvol measures the total Liouville capacity of the full carrier and is therefore too coarse to isolate the internal phase contribution, whereas ρmix is local and splitting-dependent and is therefore better interpreted as a modulation or dressing factor. By contrast, Kphase is global on the reduced dual-phase sector and thus supplies the most plausible bridge between internal phase geometry and an effective coupling factor. On this basis, we formulate the dual-phase gravitational closure conjecture at the dimensionless level: ggrav Kphase = F(Kvol). If the four-dimensional Newton-type coupling is written as Geff = ℓ2∗ ggrav, where ℓ∗ is a basic length normalization scale not derived in this paper, then the dimensional version becomes Geff = ℓ2∗F(Kvol)Kphase. The paper makes no claim to derive Newton’s constant numerically and deliberately avoids stronger assertions concerning Planck’s constant, mass formulae, or phenomenology. Its aim is narrower: to isolate the gravitationally most natural role of normalized reduced dualphase flux, while explicitly separating dimensionless geometric coupling from the additional dimensional scale required for a Newton-type coupling.
