Covariant Temporal Nucleation Theory (NTP-G): The Chronological Flow as a Scalar Field Generator of Dark Matter.

Title: Covariant Temporal Nucleation Theory (NTP-G): The Chronological Flow as a Scalar Field Generator of Dark Matter. Summary: This research presents the formalization of the García Temporal Nucleation Model (NTP-G), a theoretical framework where time (τ) is treated as a dynamic cosmological scalar field. Unlike the ΛCDM model, which assumes a constant comoving energy density for Dark Matter since the Big Bang, NTP-G proposes that the "Dark Sector" is a thermodynamically open system, receiving a continuous energy transfer from the temporal flow. Version 2 Update: Updated with High-Impact Science formatting, expanded Discussion section on Hubble/S8 tensions, and full CLASS v3.2.0 computational appendix.
