An EFT with inflaton-dependent axion kinetic term organizes direct decay and annihilation production during reheating, yielding ΔN_eff contributions that scale as T_rh^{-2} and T_rh^{4/3} respectively and allowing a two-dimensional map of constraints on Wilson coefficients and reheating temperature.

An improved Bogoliubov numerical method computes the full primordial GW spectrum from inflation to reheating and shows that inflaton anharmonicity imprints distinctive features at high frequencies.
Perturbative inflaton decay emits an irreducible stochastic GW background with Ω_GW ∝ f spectrum whose amplitude is set by the hard decay rate and reaches O(10^{-17}) at GHz scales.
Bose enhancement from a transient condensate of inflaton decay products dramatically increases decay efficiency and amplifies stochastic gravitational wave production to potentially observable levels.
