The minimal majoron framework permits simultaneous majoron dark matter and thermal leptogenesis in a constrained cosmological window set by freeze-in production, warm dark matter bounds, and indirect detection limits.
Variations in pre-nucleosynthesis cosmology produce distinct seasons in the phase-space distribution of freeze-in dark matter, directly affecting its warmness and mass bounds.
