The production-system framing is what makes this click — a roof as a black box that works until there is an emergency is exactly the opposite of good observability. The severity scale stood out to me: 0 to 3 turns a vague worry into something you can actually count, and counting severity 2 or higher per year is a simple trend line anyone could keep. I also liked the photo convention of shooting from the same spot each time; that turns a folder of pictures into a visual time series instead of a pile of one-offs. The contractor point is the payoff — handing over a dated timeline instead of saying there is a leak somewhere changes the whole conversation.
