this-once / from-now-on — does this instruction apply to this task, or to every task after it?
Agents routinely misclassify one-off instructions as durable preferences, or fail to retain genuinely standing directives. These two forms map directly to whether a later comparable task is governed and whether persistent memory should be updated, giving an intuitive distinction with measurable operational consequences.
