Although close-orbiting, massive exoplanets -- known as hot and warm Jupiters-- are among the most observationally accessible known planets, their formationpathways are still not universally agreed upon. One method to constrain thepossible dynamical histories of such planets is to measure the systems'sky-projected spin-orbit angles using the Rossiter-McLaughlin effect. Bydemonstrating whether planets orbit around the stellar equator or on offsetorbits, Rossiter-McLaughlin observations offer clues as to whether the planethad a quiescent or violent formation history. Such measurements are, however,only a reliable window into the history of the system if the planet in questionorbits sufficiently far from its host star; otherwise, tidal interactions withthe host star can erase evidence of past dynamical upheavals. We present aWIYN/NEID Rossiter-McLaughlin measurement of the tidally detached ($a/R_* =13.18^{+0.35}_{-0.37}$) warm Jupiter WASP-106 b, which orbits a star along theKraft break ($T_{\mathrm{eff}}=6002\pm164$ K). We find that WASP-106 b isconsistent with a low spin-orbit angle ($\lambda=6^{+17}_{-16}\,^{\circ}$ and$\psi = 26^{+12}_{-17}\,^{\circ}$), suggesting a relatively quiescent formationhistory for the system. We conclude by comparing the stellar obliquities of hotand warm Jupiter systems, with the WASP-106 system included, to gain insightinto the possible formation routes of these populations of exoplanets.
