Experiment E36 has recorded stopped-­kaon decay data at the J­-PARC K1.1BR beamline for a precision measurement of the ratio of decay widths BR($K^+ \rightarrow e^+\nu_e$) and BR($K^+ \rightarrow \mu^+ \nu_\mu$), respectively, to test lepton universality, and to search for rare decay modes producing light neutral bosons. An overview of the experiment and analysis status will be presented.

This work has been supported by DOE awards DE­-SC0003884 and DE­-SC0013941 in the US, NSERC in Canada, and Kaken­-hi in Japan.
