 * each task invents its own window, connector queries disagree, and the run is
 * unreproducible — re-running tomorrow silently asks a different question.
 *
 * So the range is computed once, in code, stamped into the trace, and handed to
 * the planner as a fact. Resolution is deliberately conservative: an expression
 * that cannot be resolved unambiguously is left alone rather than guessed at.
