Record a drill through its own verb, so S15 never counts a deliberate test as a repair

Two ADR 0240 drills recorded with hand-act record --cause drill raised
mesh.hand-acts.drill.healer-wanted. hand-act drill (seat verb drill) records
them as a person's decision; hand-act record now refuses the cause, so the
two recorded before it clear on the next tick and a repair cannot pass for a
drill by the word it gives.
