  "abstract": "Ultracold molecules have attracted significant interest as promising platforms for exploring fundamental physics and quantum information science. As progress toward precision measurements with the ultracold SrOH molecule is currently underway [{\\it Phys. Rev. Lett. 134, 083401 (2025)}], we present a four-component relativistic coupled-cluster (RCC) study of various parity- and time-reversal-violating (P,T-odd) interactions in the ground electronic state of SrOH. In particular, we extend the application of the Z-vector (energy-derivative) approach within the RCC framework to a polyatomic molecule for the calculation of P,T-odd molecular sensitivity parameters. We obtain the following molecular parameters for SrOH: $E_\\text{eff} = 2.12 \\pm 0.27$~GV/cm, $W_S = 1.89 \\pm 0.21$~kHz, and $W_M = (2.04 \\pm 0.12) \\times 10^{32}$~Hz/e$\\cdot$cm$^2$. These parameters provide essential molecular inputs for the design and interpretation of precision experiments with SrOH. We find that the P,T-odd sensitivity parameters of SrOH are comparable to those of the isoelectronic diatomic molecule SrF. However, the polyatomic structure of SrOH offers enhanced capabilities for suppressing systematic errors, making it a particularly promising candidate for high-precision searches for P,T violation.",
