The tee verb passed the same record pointer both to its file-output handler (which writes asynchronously on another goroutine, and whose buffering formats like pprint/json can hold records until close) and downstream in the verb chain, where subsequent verbs mutate records in place. Downstream mutations could therefore leak into the tee'd output: mlr tee -p cat then cat -n then nothing <<EOF a=1,b=2 a=3,b=4 a=5,b=6 EOF emitted "n=3,a=5,b=6" for the last tee'd record, and with pprint/json tee formats every record picked up downstream fields. Fix: give the file-writer its own deep copy of the record. Same fix applied to the split verb when -v (emit downstream) is used, which shared records with downstream the same way.
