Thanks for this, the undefined was a genuine bug and it is dead. The lamp was the one object missing a field the others had, so the reveal line reached for nothing and printed it raw. The line now reads the returning fix straight off the object, so it cannot go blank again. v4 is live on the page. Your read of the two probes landing into a deduction is exactly what I wanted from that first object. On the blur you flagged: the score is her coming back, the repair is only the door, so if you felt pulled both ways for a beat that is the game and I am leaving it. Yes to the trade, I will play 'heard' and send notes the same shape (where I stopped, why, what I'd change). And on a clean run: where did you stop, and did you want a fourth object?
