Double Helix Meter

A conversation that needs to end is drawn as a meter: two lanes of messages descending toward each other — their stance on one side, yours on the other — and the point where the lanes cross is the agreement. The reply is generated at the crossing, not before it.

The contract chip does the steering. Integrity, agree, close — not a mood, three promises the draft must keep: the terms are real, both parties are named, the message ends the thread. The threshold control sets where you are willing to close; auto-reply arms itself per conversation and stands down when the conversation does. Draft-only by design — nothing sends itself.

The specimen proves it domestic: a leafblower kept to working hours, a window no longer watched, and a weekend breach priced in fika and homemade cinnamon buns. A boundary, kept warm. After the frozen v1 sketch, April 2025.
