Reward
How a reward source accumulates, which is the one thing the epoch algorithm must know about it and the only place in the design that knows the three sources differ (§4.2.5).
TIME_INTEGRAL — a time-weighted quantity, whose accumulation is an area under a step function. Read as banked area plus area in flight: a time-weighted statistic banks the previous value's area only when a new value arrives, so for a quantity read every epoch and changed rarely the banked figure lags by the whole interval and every interval difference would be zero (§8.1.4).
OBSERVATION_SUM — the running sum of a response's observations.
COUNTER_TOTAL — a counter's value. A counter has nothing in flight.
