OPS.7:4.2 - Qualify the temporal claim before interpreting it
State the defining event, clock, observation time, horizon, and conditions. Decide whether the claim is current state, age, time remaining, rate, trend, or an intervention-sensitive temporal claim. Keep ordinary readings ordinary. Use C.27 only when an intervention is claimed to change rate, rhythm, recovery, inertia, or regime; keep the C.27.TA time-window, cadence, and currentness discipline for all temporal uses.
