F.9:12.4 - Setpoint versus service target

CTRL:setpoint and ITIL:target share a familiar word but usually have only Partial-overlap or are Disjoint under the exact readings. A proposed substitution in a control calculation receives a negative bounded-use claim because its rule and tolerance cannot preserve the physical-reference meaning. A didactic comparison may receive a different affirmative claim. Neither claim changes which Bridge obtains.
