abstract
Assuming a first order phase transition during inflation, a model scenario is described which does not require a tiny coupling constant. Thermal equilibrium is closely maintained as inflation commences. No large scale reheating is necessary. Solutions for $N> 70$ are found for any $\delta \rho / \rho$ in the range $10^{-5} - 10^{-3}$.

In warm inflation with Υ∝T³, a residual inflaton condensate after rapid drop in Q evolves as cold dark matter with mass fixed at m≈0.02 MeV by the observed abundance.
A vacuum-decay model generates primordial curvature perturbations from spatially correlated stochastic noise rather than inflaton fluctuations, solving horizon and flatness problems with zero tensor-to-scalar ratio.
SWIM solves Warm Inflation stochastic perturbations fully numerically, speeds MCMC with machine learning, and integrates with Cobaya to constrain any Warm Inflation model against CMB data.
DSWIM adds a Hubble-scaled deterministic correlation matrix evolution to SWIM that preserves the primordial curvature power spectrum exactly while improving numerical conditioning and resolving stochastic-deterministic discrepancies.
Expanded Simons Observatory could measure reheating temperature and inflaton-gluon coupling to a few percent in QCD-driven warm inflation if r=0.01 primordial gravitational waves are found.
Thermal corrections to reheating and freeze-in DM production rates are generally small in the computable regime but can be large in constructed counter-examples.
Lecture notes providing a technical introduction to naturalness problems and the string theory landscape for graduate students.
