  We consider superstrings on the pure-Ramond-Ramond $AdS_3\times S^3\times
T^4$ background. Using the recently-proposed dressing factors for the
worldsheet S matrix, we formulate the string hypothesis for the mirror
Bethe-Yang equations, and use it to derive the canonical mirror thermodynamic
Bethe ansatz (TBA) equations of the model. For the first time, these equations
account for all massive and massless modes of the model, and do not resort to
any limit or special kinematics. We also discuss the simplified mirror TBA
equations and the Y-system of the model.
