I do not want to keep rebuilding follow-ups from cold memory.
If the first touch takes research, taste, timing, and a real reason for reaching out, the next touch should be born while that context is still warm. The system should capture the thread, the reason, the next useful move, and the timing window at the moment the first message is made.
That changes the job. It is not just sending a better message. It is making sure the message creates a small operating trail that future me can actually use.
